is one of the original collection. It has narrower, more 

 falcate pods, perfectly glabrous and glossy. These two 

 species are excellent types of insular variation ; for 

 undoubtedly they had a common origin. They seem most 

 closely related to A . arrecttis judging from the character of 

 the pod. 



It was collected in two places, in high, dry gulches, 

 where it was abundant. 



To name this in honor of the discoverer, the zealous col- 

 lector, Mrs. Trask, is a small tribute to her courage and 

 enthusiasm. It is one of the most showy plants on the 

 island and perhaps the most interesting. The contrast 

 between the white stems and leaves and the nearly black 

 calyx would at once attract the attention of even careless 

 observers. 



42. Hosackia venusta, sp. nov. 



Plate VIII, Figs. 2a-2d. 



Sericeous-tomentose, loosely branching from near the base, with stems 

 2-3 dm. long: leaves scattered at internodes of 2-3 >^ cm.; lower leaves 

 unequally odd-pinnate, with two leaflets on the upper side of the rhachis, 

 three below, and one terminal ; upper leaves with five leaflets, two on each 

 side and one terminal ; rhachis 5-15 mm. long ; leaflets oblong to obovate, 

 obtuse or mucronate, 10-12 mm. long, 3-5 mm. wide : heads 2 cm. in diam- 

 eter, on peduncles 2-3 cm. long, with one simple bract subtending the head ; 

 flowers yellow streaked with brown and turning brownish red in fading, on 

 pedicels i mm. long; calyx densely villous, especially the narrow, linear 

 divisions, which are longer than the campanulate tube ; corolla surpassing 

 the calyx by about 5 mm. ; standard bright yellow, brown-veined near the 

 base of the obovate-pandurate, emarginate blade ; keel and wings brownish 

 yellow, short clawed : immature pods densely pilose with ascending hairs, 

 interiorlj- mottled with brown, exserted from the calyx and inclined to be 

 falcate ; immature seeds two, elliptical. 



This species is one of several insular types closely related 

 to H. argophylla. Two have been described by Professor 

 Greene; one, as Syrmatium niveum'', "Santa Cruz 

 Island," and Hosackia Ornithofus'^ , "Guadalupe Island." 

 On San Clemente and Santa Catalina two others occur.
