» Life History
Populations of T. aorica generally occur with galleta and salt desert shrubs In small barren openings of pinyon—juniper vegetative communities. The surface geology in the area is highly mixed and contains a wide variety of soils having unusual soil chemistries. Most known populations grow in soils derived from shale lens, that have a very fine silt texture and very high alkalinities and occur at the surface in small, isolated pockets. These pockets effectively form “islands” of suitable habitat within a nea of unsuitable geologic substrates with their resultant soil types. Although found association with several geological formations, it is limited to a small band within the shale derived soils of these formations, and has a very restricted distribution.
Movement / Home Range
Currently known from a series of small populations in Emery, Sevier, and Wayne counties, in central Utah.
Sexual reproduction, flowering occurs from April to May and fruiting occurs May to June. Self—pollination is virtually non—existent. Pollination is accomplished by several species of solitary bees: eight species of metallic blue and green inegachilid bees In the genus Osinia, and the anthophorid bee Tetralonia fulvitarsis. A few species of flies also visit the flowers. Seed set seems frequently to be pollinator—limited. Lack of pollination may be due to various reasons including low pollinator numbers, inclement weather affecting pollinator flight activity, and possibly other unidentified factors.
