474 Rydberg: Studies on the Rocky Mountain flora 



a matter of taste, but Dr. Brand in his treatment usually meant 

 by the variety a the typical form. If that is his intention here, he 

 is wholly mistaken, for the type is not viscid. Torrey's type 

 should be placed under his variety b. caespitosa, and is exactly 

 like Goodding 32 and Parry 236 from Wyoming, which Dr. Brand 

 also refers to that variety. In fact Dr. Brand seems not to know 

 Leptodactylum caespitosum Nutt. (Gilia pungens caespitosa A. 

 Gray) , although he adopts this name for a variety which proves to 

 be the original G. pungens. Leptodactylon caespitosum is amply 

 distinct, not only by the characters given by Dr. Gray, but also 

 by the 4-merous flowers and the stamens inserted in the tube. 

 All the other species have 5-merous flowers. Gilia Hookeri is 

 confined to the western slope and does not extend into Utah, 

 Colorado, New Mexico, and Arizona, as stated by Dr. Brand. The 

 following specimens are wrongly referred to it: Elmer 302 is 

 typical G. pungens; Jones 1784 and MacDougal 183 belong to G. 

 pungens squarrosa A. Gray. The Matthews' specimens I have not 

 seen, but I think they also are wrongly referred to it. Of the 

 specimens cited under the variety devestita, all I have seen belong 

 to typical G. pungens, some of them having slightly longer leaves 

 than the type, but not all. 



Leptodactylon brevifolium Rydb. sp. nov. 



Suffruticose, branched perennial, 1-2 dm. high; stems puberu- 

 lent and slightly glandular above; leaves 3-5 mm. long, glandular- 

 puberulent or glabrate, 3-5-divided into subulate, acerose, ascend- 

 ing divisions; calyx about 8 mm. long, glandular-puberulent; 

 teeth subulate-acerose, much shorter than the tube; corolla trum- 

 pet-shaped, about 15 mm. long; stamens inserted in the throat of 

 the corolla. 



This is related to Leptodactylon pungens (Torr.) Nutt. and L. 

 Hookeri (Dougl.) Rydb. (Phlox Hookeri Dougl.; Gilia Hookeri 

 Benth.) but has much shorter leaves. The habit and flower are 

 more like the former, but the calyx and young foliage are more or 

 less glandular, though not so copiously so as in the latter.
