NEW SPECIES OF APOCYNUM. 65 
A. OBLONGUM. As to hue of herbage, mode of branċhing, 
etc., quite like the last, but leaves very different, their outline 
being precisely oblong, the apex neither acuminate nor mucro- 
nate, but cuspidately acute, the base tapering to the short petiole, 
the proper cauline and those of the branches (these also mostly 
sterile) much the same as to size, 24 or 3 inches long, cyme 
mostly solitary, few-flowered; lanceolate sepals often obtusish, 
not equalling the tube of tie cylindric white pape oat follicles 
small (24 inches long). 
Species of the interior of middle California; the type being 
Geo. Hansen’s n. 1162 (of my set), collected on the Mokelumne 
River, at Clinton Bar, in July and October, 1895. In the fruit- 
ing state this bears a close resemblance to the eastern A. album. 
A fragmentary flowering specimen sent me from Monterey Co., 
by Mr. Hickman, in 1886, I now refer somewhat confidently to 
the present species; also less confidently a good specimen from 
Piute Creek, in southern California, 1893, by N. C. Wilson. 
A. SuKsporFi. Allied to the two foregoing, and with the same 
tendency to bear a single few-flowered terminal cyme and many 
very leafy but flowerless lateral branches, but hue of herbage 
very different in this and the foliage much more like A. canna- 
binum, the upper face of leaves of a rather vivid green, only the 
lower pale and glaucous; cauline leaves 4 inches long, often 2 
in breadth, elliptic-lanceolate, the lowest subcordate, all mucro- 
nately acute: flowers of the small cymes wholly white, even the 
ovate-lanceolate short sepals as white as the corolla. 
thus name, in compliment to Mr. Suksdorf, an Oregonian 
Species best represented in his n. 1522 (of my set) from sandy 
banks of the Columbia River. Both the habit of the plant, 
and its exceedingly few and white flowers forbid its being re. 
ceived as identical with the rank, freely flowering and green- 
flowered real A. cannabinum. 
A. Cero. of the A. oleate alliance, of a lighter and © 
brighter green ast lał face of the leaves, asic
