Only one collection (Reveal 1972) has been found on sandstone. The flower color changes from a whitish tinge to a pink or deep rose or even an orange color in fruit, giving tlie plants a unique color not seen elsewhere ni the spe- cies. In general the var. lupliliaila grows with sagebrush under pinyon-juniper. hi eastern California the plants grow on more exposed ridges than on the sites in Nevada, and thus the plants tend to be somewhat less spreading in the Inyo Mountains. The variety is clearly related to var. kixijlcruin although it is believed to have evolved from an ances- toral group similar to vin. pafwiniiitense. it Is with the latter variant that var. lupiJicola seems to merge based on a small sample of specimens from eastern California; however, the significance of this remains to be studied in the field. Two discordant elements related to, and likely associated with, var. hipidicola can be mentioned here. One phase is a highly depauperate population found on sandy calcareous clay soils in Lander and Eureka cos., Nevada {Ripley & Barneby 9330). These plants are similar to var. foliosum populations in northeastern Utah in size and stature, but are distinct in a number of minor moiphological Fig. 16.
