182 LEAFLETS. 



Near the boundary between the United States and Canada, 

 for northwestward, between the Columbia and Kettle Rivers, 

 within Canadian territory, collected by J, M. Macoun, 6 June, 

 1902, GeoL Surv. No. 66,555 as in my herbarium ; distributed 

 for A, androsaetnifolium. 



Apocynum ovALiifOLiUM. Plant a foot high or more, stout- 

 ish and with few and opposite brachiate branches : leaves firm, 

 even subcoriaceous, short-petioled, of exactly oval outline, 

 obtuse, inconspicuously mucronate, of a very dull dark-green 

 above and very minutely and somewhat granulately puberulent, 

 the lower face glaucescent, glabrous : cymes pedunculate, 

 terminal and subterminal, few-flowered ; sepals lanceolate, 

 acuminate, very long, equalling the tube of the corolla ; corolla 

 rather small, flesh-purple, its segments elongated-oval, almost 

 as long as the tube. 



Collected along Rogue River, Jackson Co., Oregon, 21 Aug., 

 1897, by Mrs. R. M. Austin. Manifestly of the group of A. 

 androsaemifolium despite the fact that its corolla-tube, though 

 short, is not campanulate but short-cylindric ; also the flowers 

 are nearly erect, which is also out of character for the group. 

 The indument of the surface of the leaf is very minute ; perhaps 

 a g^ranular coating merely, but it imparts a dulness of color 

 that is peculiar. 



Apocynum rubicundum. Plant large and stout, glabrous 



in every part, the foliage spreading or deflexed, of a firm 

 almost coriaceous texture, all the leaves oval, the largest 3 

 inches long, 2 inches wide, distinctly petiolate, the base very 

 obtuse, the apex also rounded, but conspicuously mucronate, 

 dark-green above, pale beneath : flowers many in clusters 

 terminal and subterminal and borne beyond the leaves ; sepals 

 ovate-lanceolate ; corolla small, rather narrowly campanulate, 

 but deeply cleft, of a pale rose color. 



Collected by Kirk Whited, at Stines, Chelan Co., Wash- 

 ington, 11 Aug., 1901, and distributed with no show of reason 

 for A, pumilum. The plant is larger and stouter than the 



t".
