Rocky Mountain Flora 249 



Cleomella cornuta sp. nov. 



Annual : stem straw-colored, 2—3 dm. high, branched below 

 with ascending branches, glabrous throughout : leaves ternate ; 

 petioles 1-1.5 cm. long ; leaflets 1—2 cm. long, oblong or oblong- 

 oblanceolate, obtuse, mucronate : inflorescence short : pedicels 

 very slender, almost i cm. long : sepals yellowish, ovate, cuspi- 

 date, less than i mm. long : petals light yellow, narrowly oval, 

 clawless, about 3 mm. long : filaments about twice as long : fruit 

 broadly rhombic, broader than long, about 3 mm. long and 4 mm. 

 broad ; the corners often produced into short processes : stipe 6— 

 8 mm. long; beak over i mm.: seeds about 2.5 mm. long, 1.75 

 mm. wide, smooth and unmarked. 



This is related to C. oocarpa and C. plocaspcniia, but has 

 broader leaflets. From the former it also differs in the strongly 

 rhombic pod and from the latter in the broader and unmarked 

 seeds. The type grew at an altitude of 1350 m.

Cerastium Earlei sp. nov. 



Perennial with a slender branched and stoloniferous root- 

 stock : stems weak, ascending, 2—3 dm. high, viscid-puberulent, 

 branched : leaves oblong or oblanceolate, obtuse, viscid-puber- 

 ulent, 1.5—3 cm. long, 3-8 mm. wide: inflorescence open; 

 bracts ovate or ovate-lanceolate, not scarious ; pedicels 2—2.5 cm. 

 long : sepals lanceolate, acute, sparingly pubescent, scarious on 

 the margins, about 5 mm. long : petals about i cm. long or more, 

 fully twice as long as the sepals, not very deeply cleft. 



The type number was determined by M. E. Jones as Cerastium 

 alpiiium near var. glabratia>i, and the other two numbers of the 



Baker, Earle and Tracy collection are labeled Cerastiinii , 



and Cerastium arvcuse oblongifoliuui, respectively. The six sheets 

 (two of each number) in the N. Y. Botanical Garden herbarium 

 (except one of number 621, which represents a luxuriant state) 

 are so alike that it is impossible to refer them to different species. 

 In the size of the flowers, form of the leaves and general habit, 

 the species resembles most C alpiiium, but the pubescence is 

 different : in C alpiiium long-villous and less viscid, in C Earlei 

 very short and very viscid. The latter grows at an altitude of 

 2700-3600 m.
