This page has been created for people who want to learn more about plants, especially in the context of their taxonomy (Latin names, etc.). This is by no means an exhaustive list of all available Web resources for a particular genus.
If you like this page, you might also want to visit the Land of the Glandular Trichomes , a microscopic look at plants in the Lamiaceae family. Also, you can see my contribution to the Conservation New England web site, entitled "The Introduction of Non-Native Plants into Massachusetts".

Subclass: Dicotyledoneae
Superorder: Asteridae
Order: Scrophulariales
Family: Scrophulariaceae (occasionally placed in the Orobanchaceae)
Subfamily: Rhinanthoideae
Number of Species: about 200
Root: Named for the Spanish botanist Domingo Castillejo (Ref)

The genus Castilleja is semi-parasitic; individual plants can tap into the roots of their neighbors if they need a nutrient fix. Species in this genus are frequently grown for ornamental purposes. Their spectacular floral displays are enhanced by brightly colored bracts and bracteoles, which are not petals but are in fact modified leaves.

Here are a few links to images and descriptions of different Castilleja species:
