Rydberg: Studies on the Rocky Mountain flora 471 



Dr. Brand evidently drew his description from Jones 5949, the 

 only specimen he cited. He described the stamens as being in- 

 serted in the middle of the corolla-tube, while Nuttall described 

 them as inserted in the throat. I have not seen Nuttall's type, but 

 I have collected in the region of the type locality, Scott's Bluffs, 

 Nebraska. The only species growing there are G. spicata and G. 

 iberidifolia. I believe that Dr. Gray interpreted G. trifida Nutt. 

 correctly as a depauperate form of G. spicata. If this is correct, 

 Brand's G. trifida must receive a new name. 



Gilia frutescens Rydb. sp. now 



Fruticose, perennial; stems woody below, branched above, 3-5 

 dm. high; herbaceous branches 2-3 dm., sparingly pubescent; 

 leaves linear, glabrous or nearly so, simple, 2-5 cm. long, 1-2 mm. 

 wide, callous-tipped; flowers capitate at the ends of the branches; 

 calyx crisp-hairy; teeth lanceolate, cuspidate, shorter than the , 

 tube; corolla white, 5-6 mm. long, salvershaped ; tube barely 

 exserted; lobes about 2.5 mm. long, oval, acute; stamens inserted 

 in the throat; filaments short; style glabrous, nearly as long as 

 the corolla tube. 



The type was labeled Gilia multiflora, to which it is not related. 

 It belongs to the G. iberidifolia group, and has as entire leaves as 

 G. spergidifolia and G. crebrifolia, but the habit is different. It 

 differs from all its relatives in the tall shrubby habit. The other 

 species are at most suffruticose and less than 3 dm. high. 



Utah: Springdale, May 14, 1894, M. E. Jones 5247 (type, in 

 herb. N. Y. Bot. Gard.; duplicate in U. S. Nat. Herb. no. 326910). 



Dr. Brand has treated the G. aggregata group as carelessly as 

 that of the G. congesta relatives. It is evident that he has had no 

 specimens of G. Candida Rydb. and still he makes it Gilia aggregata 

 var. attenuate forma Candida, giving Callisteris leucantha Greene 

 as another synonym. If he had only read my description, he 

 would not have committed this blunder, for I distinctly pointed 

 out that the lobes of the corolla in G. Candida are rounded or 

 obtuse at the apex like those of G. longiflora. It is a plant with the 

 habit and leaves of G. aggregata and the corolla of G. longiflora. 

 Both Callisteris attenuata and C. leucantha have attenuate corolla- 

 lobes and the former is a white-flowered form of Gilia pidchella 

 Dougl.,* a species wholly omitted by Dr. Brand. Dr. Brand cited 



* Hook. Fl. Bor.-Am. 2: 74. 1838.
