VOL. IV.] Plants Collected in Southeastern Utah. 123 



the opposite is the case; the ovules are much more numerous in 

 this species, and shaped differently. 



The plants were collected at Hatch's Wash, in southeastern 

 Utah, between Moab and Monticello, on May 29, 1892. They 

 were abundant in a limited area, on sandy knolls formed by the 

 accumulated sand that had been washed down from the basin^ 

 like sides of the shallow caiion, and were not met with at any 

 other place. 



96. Phlox nana. Growing at the base of a cliff between 

 Hatch's Wash and Monticello. 



y 97. Phacelia nudicaulis n. sp. Annual, low, and almost 

 prostrate, stems several (4-7) from the root, naked to the inflor- 

 escence, nodes 1-2 cm. long, internodes shorter; glandular and 

 hirsute, with short, white bristles; leaves thick, orbicular, or 

 broadly ovate, abruptly tapering to the petiole, blade about i cm. 

 long by not quite so broad, petiole equalling or surpassing it in 

 length, margins slightty undulate and revolute; radical leaves 

 few; cauline, crowded at the ends of the branches, surrounding 

 and almost hiding the flowers, which are solitary in the forks of 

 the branches or in few flowered spikes which are cymosely 

 arranged; sepals linear-spatulate, united at base, spreading, and 

 surpassing the capsule; corolla 3 to 5 mm. long, surpassing the 

 immature calyx, violet, tubular funnel-form, with rounding lobes 

 acute or obtuse, hairy on the outside but smooth within, the folds 

 at the base linear and attached to the stamens; filaments smooth, 

 equally inserted, but of unequal lengths; style cleft half-way 

 down, with capitate stigmas, hairy to the forks; capsule blunt, 

 hairy; seeds about 16, oblong, pitted, variable in thickness, from 

 flat to lens-shaped, probably modified by the pressure from each 

 other in the crowded cells. 



This desert Phacelia was collected on the road from Thomp- 

 son's Springs to Moab, May 24, 1892. It grew on a flat, adobe 

 desert with Cleomella plocasperma {?), and was abundant 

 over a very limited area. It most nearly approaches P. cephalotes 

 Gray, from which, however, it is quite distinct. 



98. Phacelia cephalotes Gray. This presents some very 

 interesting variations in the style branches. In some flowers it
