Looking at Floral Structure BOT 127

Kanchi Gandhi, Botanist, Harvard University Herbaria
4 Sessions
Tue Jul 8, 15, 22, 29 6:30–8:30pm [HUH]

Charles Darwin called the origin of flowering plants an “abominable mystery.” The diversity found in floral structure makes it easy to understand his frustration. In this basic overview, Kanchi Gandhi will teach you to look at flowers as the complex structures that they are with slides, handouts, and dried and fresh specimens. You will learn floral characters of some of the major plant groups (families) such as magnolias, amaranths, mustards, legumes, roses, poinsettias, oranges, parsleys, mints, squashes, sunflowers, and orchids. Participants will also learn to use keys to identify plant families. Bring a hand lens if you have one. Click here for more info.
