FIG. 33.21 Monocot diversity and phylogeny. This diverse group of angiosperms includes (a) Agave shawii, a desert succulent; (b) Leucojum vernum, a spring wildflower; (c) bamboo, a forest grass; and (d) Costus species, which grow in the rain forest understory. (e) Monocot phylogeny indicates that orchids (~22,000 species) and grasses (~11,500) make up much of monocot diversity.
