ACCESSIONS TO APOCYNUM. 167 



feather veins ; properly cauline leaves very large, conspicu- 

 ously and stoutly petiolate, the blades of long-oval outline, 4 

 inches long, 2% inches wide, obtuse at both ends, at apex 

 strongly mucronate, those of the branches less than half as 

 large, varying from oval-elliptic to elliptic, all of very firm 

 texture, even rigid, and pale beneath as with bloom, but also 

 roughened along the veins and all veinlets with stiffish white 

 hairs : cymes rather many, those of the lateral branches far 

 surpassing the terminal ; sepals broadly lanceolate, acute or 

 acuminate, more than equalling the tube of the short and sub- 

 cylindric green corolla the lobes of which are broad and obtuse 

 as well as very short. 



Wells County, Indiana, in low ground, bordering lakes in 

 Jackson Township, Chas. C. Deam, 23 July, 1895. 



Apocynum Sarniense. Perhaps a yard high, but with 

 few and suberect branches, both stem and branches purplish 

 and pubescent with short curved dark-colored hairs ; cauline 

 leaves 3 inches long, more than half as wide and of long-ovate 

 outline, short -petioled, rounded at base, the apex rather acute, 

 sharply mucronate, the upper face rather bright green, glab- 

 rous, the lower paler and with a thin coat of whitish tomentum : 

 cymes few-flowered, terminal on both main stem and each 

 branch, but the branches subequal ; sepals triangular-lanceo- 

 late, acute, these and the exterior of the corolla tomentulose ; 

 corolla pinkish, very large for the cannabinum group and dis- 

 tinctly campanulate, cleft well toward the middle and the 

 lobes acutish. 



Type specimen in U. S. Herb, sheet 444,792, collected 3 

 Aug., 1902, at Sarnia, Lambton Co., Ontario, by Charles K. 

 Dodge. The species, though of the cannabinum group, has 

 flowers as much like those of the other section as have some 

 of the Pacific species ; but the flowers are not quite erect, 

 another circumstance to render the plant another connecting 

 link between two groups which one would like to regard as 

 subgenerically distinct.
