472 Rydberg: Studies on the Rocky Mountain flora 



two specimens under the forma Candida, viz. Nelson 41Q8 (should 

 have been 41 8q) and Clements 13. The former is a white-flowered 

 form of G. pulchella, the latter belongs to Gilia scariosa Rydb. 

 Dr. Brand did not notice the different structure of the calyx, which 

 places G. scariosa close to G. aggregata Bridgesii A. Gray, Nelson 

 in the New Manual has also confused things. Gilia scariosa is 

 made a synonym of G. aggregata and G. Candida of G. attenuata. 

 He has also overlooked the characters of the calyx of G. scariosa 

 and the rounded corolla-lobes of G. Candida.

Gilia tenuituba Rydb. sp. nov. 



Biennial; stem about 3 dm. high, finely glandular-puberulent; 

 leaves pinnatifid with narrowly linear, puberulent, cuspidate divi- 

 sions; inflorescence a thyrsoid panicle, puberulent; flowers short- 

 pedicelled; calyx campanulate, glandular-puberulent, distinctly 

 scarious in the sinuses; teeth lance-subulate, cuspidate, longer 

 than the tube; corolla flesh-colored, nearl}^ 4 cm. long; tube slender, 

 I mm. thick below and 2 mm. at the throat; lobes narrowly lanceo- 

 late, attenuate, nearly i cm. long; stamens unequally inserted 

 far down the corolla-tube, included ; style slender, about equaling 

 the corolla-tube. 



Utah: Beaver City, 1877, E. Palmer J2Q (type, in herb. 

 Columbia Univ.). This is also related to G. aggregata. 



Gilia hutchinsifolia Rydb. sp. nov. 



Gilia arenaria rubella Brand, Pflanzenreich 4-^": 103. 1907. 



This differs from G. arenaria Benth. and G. sinnata Dougl. in 

 the acute corolla-lobes and broad and again lobed divisions of the 

 leaves. The description " Caidis inferne (an morbo?) riifo- 

 lanatus," from which Dr. Brand adopted the varietal name, is 

 wholly erroneous. The red coloring is simply grains of red sand 

 adhering to the specimens. This is the reason of my not adopting 

 the varietal name. 



Gilia straminea Rydb. sp. nov. 



Annual; stem 2-3 dm. high, glabrous, or rarely slightly glandu- 

 lar-puberulent above, straw-colored, simple below, with a few
