ACCESSIONS TO APOCYNUM. 187 



orbicular, 1 inch across, the next slightly verging to ovate, 

 1/i inches long, all nearly sessile, widely spreading, none 

 deflexed, of subcoriaceous texture, dark green above, very 

 glaucous beneath, cymes both terminal and axillary small and 

 on short peduncles ; sepals broadly and deltoidly lanceolate, 

 their slender tips recurved ; corolla purplish, large, the tube 

 subcylindric, slightly ventricose, being a trifle constricted 

 under the comparatively very short lobes, these of barely one- 

 third the length of the tube, obtuse and recurved. 



Known chiefly as collected in the Sierra Nevada of Califor- 

 nia, somewhere in Placer Co., in Sept., 1892, by A. M. Car- 

 penter. 



Apocynum arcuatum. Dwarf barely 7 inches in height, 

 but the plant by virtue of its long and recurved branches 

 measuring more than a foot across ; all the herbage puberu- 

 lent, both faces of the leaves hirtellously so, the lower quite 

 pale with bloom, the upper dull dark green : all the lowest 

 leaves small and subreniform, those next them orbicular, the 

 others round-oval, the largest about an inch wide : flowers 

 very large, but not very numerous, in short and subsessile 

 terminal and lateral cymes ; sepals short, lance-ovate, these 

 and the pedicels villous-pubescent : corolla with subcylindric 

 tube only very slightly wider above than below, the segments 

 in length approaching that of the tube, elongated-oval, little 

 spreading. 



The plant is known to me only as collected in 1892 by Mr. 

 Jepson, the locality being the South Fork of Eel River, Cali- 

 fornia, a station that might lie in L,ake County or Mendocino, 

 probably Lake. It forms part of my ^. pumilum published in 

 the Bay-Region Manual, and is my sole warrant for attributing 

 to the species there so. named the character of subreniform lower 

 leaves. By this mark, fortified as it is by the arcuate and 

 elongated branches, and flowers of their own peculiar pattern, 

 the plant must claim specific rank ; and since nothing of this, 

 nor of anything much like it, was ever seen by Asa Gray, it
