Yellow cryptanth), the petals are united to form a trumpet­shaped tube. ) The generic name, Lithospermum, refers to the plant's rock­hard seeds.  Like prince's plume, seed pods and flowers of tansy mustard will grow on the same plant.  François Descurain was an eighteenth­century French botanist.  Narrow, linear leaves are concentrated at the base with a few leaves ascending the stem.  Western wallflower's elevation range, from 2,490 to 12,467 feet, is the broadest among plants in Utah. Twinpod Physaria sp.

The group of petals makes up the corolla.  It is topped by the stigma, which rests atop the style, which in turn connects to the ovary. Page 50 Plants can have either both male and female parts on the same plant (monoecious) or on separate plants (dioecious).  This disk, in turn, surrounds a tinier tube of five fused stamens.  The pollinator then flies or crawls to the next flower where the pollen is deposited onto the stigma and pollination takes place.  Most pollination, though, occurs during the day, so color and shape are important for attracting visitors.

Snakeweed leaves are 1 to 3 inches long and often sticky.  A corollary to this deep root development is that these southern plants have larger canopies and drop fewer leaves during the summer than their northern counterparts. The generic name refers to Pedro Gutierrez, a nineteenth­century correspondent for the Botanic Garden in Madrid.  Although they often grow along roadsides, encelia also can be found on talus and slickrock associated with blackbrush and shadscale. The genus name honors Christopher Encel, an English botanist who wrote a book on oak galls in 1577.
