472 RYDBERG: STUDIES ON THE Rocky MOUNTAIN FLORA 
two specimens under the forma candida, viz. Nelson 4198 (should 
have been 4189) 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 Bridgesti A. Gray. Nelson 
in the New Manual has also confused things. Giulia 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 arizonica (Greene) Rydb. 
Callisteris arizonica Greene, Leaflets 1: 160. 1905. 
Gilia aggregata typica arizonica Brand, Pflanzenreich 4”°: 115. 
1907. 
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, nearly 4 cm. long; tube slender, 
1 mm. thick below and 2 mm. at the throat; lobes narrowly lanceo- 
late, attenuate, nearly 1 cm. long; stamens unequally inserted 
far down the corolla-tube, included; style slender, about equaling 
the corolla-tube. ; 
Uran: Beaver City, 1877, E. Palmer 329 (type, in herb. 
Columbia Univ.). This is also related to G. aggregata. 
Gilia hutchinsifolia Rydb. sp. nov. 
Gila arenaria rubella Brand, Pflanzenreich 42°: 103. 190 
This differs from G. arenaria Benth. and G. sinuata Dougl. in 
the acute corolla-lobes and broad and again lobed divisions. of the 
leaves. The description ‘‘Caulis inferne (an morbo?) rufo- 
lanatus,” from which Dr. Brand adopted the varietal name, is 
wholly erroneous. The red coloring i 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
