Linking physiological traits to impacts on community structure and function: the role of root hemiparasitic
Heckard (1962) examined hemiparasitic
Castilleja species growing with and without hosts and noticed that generally plants growing as parasites are more vigorous, branch more profusely, and exhibit early flowering.
upon their host plants have not been methodically evaluated, but 5 or more of these hemiparasitic
plants may occur per host tree.
auriculata's annual and hemiparasitic
habit, our "snap shot in time" genetic analyses offer additional insights into the biology of the species and establish base-line data that can be used to compare additional populations throughout its range as well as assessing how the populations in Illinois may change through time.

Transpiration and carbon acquisition in root hemiparasitic angiosperms.
The genus Castilleja (Scrophulariaceae), commonly known as Indian paintbrush, is a group of hemiparasitic
root parasites, many of which are able to parasitize an enormous range of angiosperm taxa (Heckard 1962).
Here I report the results of a greenhouse study on the direct interactions of a hemiparasitic
, or partially autotrophic, plant with three of its major host plant species as well as the indirect effects of this parasitic interaction on an aphid herbivore of the parasite.
