ACCBSSIONS *0 APOCYNUM. 171 



Green Tree Falls, not far from Ithaca, New York. ' ' I refer here, 

 with some hesitancy, a plant gathered in southern Pennsylvania, 

 at the "mouth of the Yucquan," in 1893, by Mr. Heller. 

 While much like the present species in most particulars, it is 

 much more whitened with bloom ; and the different shades of 

 color in herbage are not to be disregarded in classifying plants 

 of high organism. 



Apocynum subuwgerum. Plant probably tall, and simple 

 up to the ample compound-cymose and altogether terminal 

 inflorescence, all parts glabrous, glaucous ; cauline leaves 

 somewhat lance-oval, 2/^ to 3/4 inches long, sessile by a sub- 

 cordate base, acutish at apex and almost subulate-mucronate, 

 upper face of a deep copperas-green , the lower paler ; rameal 

 leaves of half -size and tapering to both base and apex, are 

 elliptical : inflorescence of 1 or 3 large corymbose panicles at 

 summit of stem and borne on long peduncles quite above the 

 foliage, the branches of it conspicuously beset at the joints by 

 long slenderly subulate or almost aristiform bracts ; sepals 

 similarly subulate-attenuate above the lanceolate base and 

 equalling the corollas, these small, not cylindric as in most 

 cannabinum allies, but distinctly campanulate, erect, their lobes 

 deltoid-ovate, slightly acutish. 



Type specimens in my own herbarium, sheet 7022, com- 

 municated to me many years since by Dr. J. Bernard Brinton, 

 but as having been collected somewhere in the State of Maine 

 as long ago as 1878, by F. I/. Scribner. I have seen no eastern 

 specimens making any approach to this in mode of growth and 

 inflorescence. This, in the larger of the two specimens, is as 

 a whole almost flat-topped, measuring seven inches across. 

 In this particular it recalls my far-away Calif ornian A . flori- 

 bundum and some others of the West. I name it in allusion 

 to the great length and slenderness of the bractlets and sepals. 



Apocynum littorai,e. Akin to A. album, taller and 

 more robust, less widely branching, herbage of a darker green;
