Rated 5 out of 5 by from Great course for learns at many levels Professor Kleier has a contagious enthusiasm for Botany. The variety within the world of botany is truly amazing. But, with that variety professor Kleier teaches us the basic indicators to help identify plants. The course will deepen my appreciation for the plant world has we travel about North America.

Rated 5 out of 5 by from Boyany For the Common Man What I enjoyed most about this course is the enthusiasm that the guest lecturer brings to the subject. Too many times I have sat in college courses listening to the drone of a professor who has tired of the academic process. But here...the teinkle in her eyes, the smiles, the enthusiasm is contagious...One can tell that she absolutely loves her subject and is excited to bring to the public her knowledge.

Rated 5 out of 5 by from So interesting and professionally taught I love this course! It’s my first course on GC and I am very satisfied. I find the teacher very relatable and friendly, it’s fun to learn with her instruction. The little anecdotes and “jokes I made up” make it all more human. I’m impressed by the density of information in this course. I chose this as something good to do for myself during a pandemic lockdown and I am so glad I did! I’ve already been looking at the irises and daffodils in the vase with a new “botanist’s eye”.

Rated 5 out of 5 by from Took my wildflower hikes up several notches! I've been a wildflower enthusiast for decades, know my way around my old Peterson wildflower guide, and am pretty good at identifying many common U.S./Canadian plant families, but this course has upped my wildflower *and* gardening game, and given me a more precise vocabulary for describing the differences I see between related plant species. Dr. Kleier has once again presented a fun, accessible, informative course that has prepared me to ask yet more detailed questions. I listened to the whole course but selected a few minutes in a couple of lectures where it was useful to watch the video.

Rated 5 out of 5 by from Up to Date Information I asked for exactly such a course in a Great Courses survey a year or so ago. This class is precisely what I needed since my education is 50 years out of date. The instructor, Dr. Kleier, is even better than in her previous course, Plant Science. Thank you for this course!

Rated 5 out of 5 by from So excited to learn this I love that this course is really dense in the facts. I don't want a lot of blah blah just stick to the facts, and Prof. Klein does that. I am on lecture 2 and so far really enjoying that it is information dense and really interesting.

Why Learn the Names of Plants?
1: Why Learn the Names of Plants?

Knowing how to name plants can help you develop a better relationship with the outdoors. In this introductory lesson, get a brief overview of how life is divided and classified, walk through an example of taxonomy using a ponderosa pine tree, and consider helpful tools every good casual botanist may need.

30 min
Before There Were Flowers
2: Before There Were Flowers

Non-flowering plants have been on Earth longer than plants with flowers. Here, start with mosses, liverworts, and hornworts. Then turn to ferns and fern allies and discover tried-and-true methods for identifying them. Lastly, consider several phyla of gymnosperms and their species, including the Gingko tree.

30 min
Plants Are Named like People
3: Plants Are Named like People

Dive into the many classification systems botanists used (and still use) to name plants. Among these are the binomial system popularized by Carl Linnaeus; the phenetic classification system, which aimed at revealing relationships based on shared characteristics; and the three ways botanists determine the ancestral traits of plants.

32 min
Organizing the Huge Diversity of Plants
4: Organizing the Huge Diversity of Plants

Professor Kleier helps you to make sense of the Angiosperm Phylogeny Group (APG), which botanists now use to classify flowering plants. You’ll learn how APG came about, what it does, and why it’s so important to field botanists. Then you’ll explore the six guiding principles for naming a plant species.

30 min
The Language of Botany
5: The Language of Botany

From roots and stems to leaf hairs and fruits, learn to determine the parts of plants so you can make your own identifications in the field. What are the two main types of root systems? What are the most common leaf arrangements? What are the three different symmetry types for flowers?

32 min
What the Terms Monocot, Dicot, and Eudicot Tell You
6: What the Terms Monocot, Dicot, and Eudicot Tell You

Embark on your in-depth exploration of the major plant families. First, learn to recognize the difference between monocots and eudicots. Then, explore the most ancient plant family in North America and four basal angiosperms. Among the plants you’ll encounter are: water lilies, magnolia trees, pawpaws, and avocado trees.

26 min
Parts of Three: The Monocots
7: Parts of Three: The Monocots

In this lesson, investigate monocot plants, which grow from bulbs and tend to bloom early in the spring. You’ll cover the Easter lilies of the Liliaceae family, the purple heart of the Commelinaceae family, the corpse flower of the Araceae family, and the Arecaceae (or Palmae) family with its instantly recognizable palm trees.

28 min
Monocots: Orchids, Asparagus, and Irises
8: Monocots: Orchids, Asparagus, and Irises

Continue your look at monocots with a lesson on four more plant families: the Orchidaceae (the second largest family of flowering plants); the Asparagaceae (which does include asparagus as well as agave plants); the Amaryllidaceae (which includes daffodils and paper whites); and the iris family, or Iridaceae.

31 min
Grassy Monocots: Grasses and Relatives
9: Grassy Monocots: Grasses and Relatives

The grasses, or Poaceae, are fairly easy to recognize—but are rather difficult to break down into individual species. There are four families you’ll learn about in this lesson: three which look superficially like grasses (rushes, sedges, and cattails), and the Bromeliaceae, or the pineapple family.

30 min
Early Eudicots: Buttercups and Poppies
10: Early Eudicots: Buttercups and Poppies

Now, enter the largest group of flowering plants: the eudicots, which all form a good group because they all have a similar pollen structure. Professor Kleier discusses three families (Ranunculaceae, Berberidaceae, and Papaveraceae) and also shares the floral diagrams and formulas botanists use to remember plant family characteristics.

28 min
Eudicots: Crassula, Euphorbs, and Willows
11: Eudicots: Crassula, Euphorbs, and Willows

You’ve already met some succulents in the Asperagaceae family, which includes agaves. Here, meet two other families that include succulents, the Crassulaceae and the Euphorbiaceae, and some other plant families that decidedly don’t include succulents but are related: Saxifragaceae, Violaceae, and Salicaceae.

29 min
Eudicots: Peas and Beans
12: Eudicots: Peas and Beans

The Fabaceae family is so diverse and so prevalent in the Northern Hemisphere that it deserves its own lesson. Home to important crops such as soybeans, green beans, peas, and alfalfa, this fabulous family is easily recognized by the “wings, banner, and keel” arrangement of the flowers.

27 min
Rose Eudicots: Roses, Mulberries, and Elms
13: Rose Eudicots: Roses, Mulberries, and Elms

The economically important rose family produces many tree fruits, including cherries, plums, apricots, nectarines, peaches, and almonds. Here, explore the rose family, the Rosaceae and some closely related families: the Moraceae, the mulberry or fig family; the Ulmaceae, or elm family; and the Cannabaceae, the hemp, hops, and hackberry family.

28 min
Eudicots: Squashes, Oaks, and Birches
14: Eudicots: Squashes, Oaks, and Birches

In this lesson, look at the Cucurbitaceae, the cucumber and gourd family, and the Fagaceae, the oak family, both of which are defined by their fruit types. Also consider three families closely related to oaks: the walnut family (Juglandaceae), the birch family (Betulaceae), and the “she-oaks” common to tropical beaches (Casuarinaceae).

28 min
Eudicots: Maples, Cashews, and Chocolate
15: Eudicots: Maples, Cashews, and Chocolate

Meet five plant families that are mixed in terms of woody and herbaceous members. Begin with the Sapindaceae, which in addition to maples, includes lychee. Continue with the cashew family, the Anacardiaceae; the Malvaceae, the mallow family, which includes hibiscus, cotton, and chocolate; and the Geraniaceae, or the geranium family.

29 min
Brassica Eudicots: The Mustards
16: Brassica Eudicots: The Mustards

Why learn to recognize the Brassicaceae? Because, as you’ll learn, it's the sixth largest family in North America, including around 650 species. And one of them, Brassica oleracea, has been cultivated into kale, collard greens, Brussels sprouts, broccoli, cauliflower, red and white cabbage, Chinese broccoli, and other delicious vegetables.

30 min
Pink Eudicots: Pinks, Cacti, and Relatives
17: Pink Eudicots: Pinks, Cacti, and Relatives

In this lesson, learn the easiest way to recognize a carnation in the wild (hint: look at the leaves); gain a greater appreciation for the humble tumbleweed (also known as the Russian thistle); and explore the cactus family, with their iconic modified leaves (botanically called spines) and smaller bristles (called glochids).

28 min
Heath and Dogwood Eudicots
18: Heath and Dogwood Eudicots

Which plant genus produces berries that are almost all edible? What relationship exists between roses and rhododendrons (Greek for “rose tree”)? How can you determine whether or not a tree or shrub belongs to the dogwood family? Discover answers to these and other questions about heath and dogwood eudicots.

27 min
Gentian Eudicots from Milkweed to Coffee
19: Gentian Eudicots from Milkweed to Coffee

First, take a closer look at the milkweeds and dogbanes of the Apocynaceae family, known for their opposite leaves and milk sap. Second, learn about the Rubiaceae family, which gives us gardenias, quinine, and coffee. Lastly, consider the beautiful blue gentians in the Gentianaceae family—some of the only true-blue plants around.

29 min
Tomato-Type Eudicots
20: Tomato-Type Eudicots

Most of the plants you’ll meet in this lesson are herbaceous and have petals joined at the base. They are the Solanaceae, or nightshade family (which includes tomatoes and peppers); the Convolvulaceae family, whose members are usually vines; and the Boraginaceae, whose generally hairy members include the forget-me-nots.

28 min
Minty Eudicots with Liplike Flowers
21: Minty Eudicots with Liplike Flowers

In this lesson that focuses on liplike flowers, Professor Kleier introduces you to one of the easiest plant families to identify—the Lamiaceae, or mints—and one of the hardest: the Plantaginaceae, or plantain family. Plus, explore an intriguing plant family, the Orobanchaceae, whose plants are partly (if not all) parasitic.

28 min
Sunflower Eudicots: More than You Think
22: Sunflower Eudicots: More than You Think

What makes a weed a weed? Turns out, it’s not a botanical term at all—it’s just the name for plants that grow where they’re not wanted. In this lesson, you’ll meet two families: the bell-flower family, or the Campanulaceae; and the sunflower family, or Asteraceae, which includes everyone’s favorite weed, dandelion.

31 min
Parsley Eudicots: Plants with Umbels
23: Parsley Eudicots: Plants with Umbels

Examine a family of plants (known for their compound umbel inflorescences and hollow stems) that include a great many herbs and spices—coriander, cumin, cilantro, dill anise, and fennel—as well as some very toxic plants including poison hemlock. Also, consider examples from the ginseng family and the honeysuckle family.

27 min
Now You See Plants
24: Now You See Plants

To conclude the course, Professor Kleier gives you a brief review of 20 plant families: 10 of the most speciose and 10 she considers just as important. Then, she offers her insights on the future of botany and how new genetic evidence could change how we identify certain plants.
