* Gilia parvula. 



Annual, only 2-3 cm. high, glabrous ; stem naked from the per- 

 sistent small cotyledons to the inflorescence, which is capitate ; bracts 

 foliaceous, ovate-lanceolate, 5-15 mm. long, often tinged with red; 

 calyx about 3 mm. long, its lobes ovate, acute ; corolla white or 

 pinkish, 6-8 mm. long, salverform, the tube somewhat cyanthiform- 

 dilated at the throat ; limb with narrowly obovate acutish lobes 

 I— 1.5 mm, long; anthers short, sessile in the throat of the corolla; 

 capsule 3-4 mm. long, ovoid, containing about a dozen seeds. 



This has been confused with G. midicatdis, to which it is nearest 

 related ; it differs, however, in being smaller and having smaller 

 flowers. In G. midicanlis the lobes of the corolla are broadly 

 cuneate, truncate, undulate-toothed at the apex, and 3-4 mm. long- 

 In sandy places, at an altitude of 1500—2500 m. 



Yellowstone Park: Swan Lake, 1885, Tzvecdy, 82J.
