ACCESSIONS To AfOCYNUM. 189 



Apocynum luridum. Low, widely branched from an inch 

 above the base, but only 8 inches high, the branches copiously 

 leafy, but the leaves ascending, or only spreading, large for 

 the plant, those at summit as large as those near the base, and 

 fully equalling when not surpassing the sessile inflorescences ; 

 lowest leaves small, orbicular, the next large, suborbicular, 

 retuse, the rest oval, obtuse, mucronulate, average length of 

 leaves more than 1 inch, all glabrous, deep but hardly dark 

 green above, glaucous beneath ; sepals ovate, acuminate, short 

 for the corolla, this nearly cylindric as to the rather broad 

 tube, the oval obtuse lobes of more than one-third the length 

 of the tube and spreading, the whole of a deep lurid purple 

 like that of some solanaceous flowers. 



Lassen Creek, Modoc Co., California, Aug., 1894, Mrs. 

 Austin, the only specimen being in my own herbarium, n. 

 7107. 



Apocynum diversifolium. Plant 10 inches high, simple, 

 rather closely leafy from base to summit, sparsely pubescent 

 as to stem and both faces of the leaves, of which the lower 

 pairs are orbicular, % inch across, those in the middle portion 

 of the stem ovate, 1% inches long, the uppermost pairs oval 

 and smaller, all obtuse, faintly mucronate, dark green above, 

 paler beneath ; terminal inflorescences borne well above all 

 foliage, the lateral cymes when present surpassing the leaves 

 subtending them ; sepals short, ovate, scarcely acute ; corolla 

 purplish, of a broad cylindric tube and rather large oval obtuse 

 reflexed segments. 



Collected at Fredalba in the San Bernardino Mts., south- 

 ern California, 22 July, 1902, by LeRoy Abrams, distributed 

 for A . pumilum as many another excellent undescribed species 

 has been. This one, like several other of the dwarf kinds of 

 California and Oregon, departs somewhat from the general 

 characteristics of androsaemifolium allies in that the corollas 

 are nearly erect, never quite nodding.
