Accessions to Apocynum. 



Apocynum cordigerum. Stem low for one of the A. can- 

 nabinum group, hardly 2 feet high, very robust, densely leafy 

 throughout with an ample firm yellow -green glabrous foliage, 

 the inflorescences small, dense, none rising above the height 

 of the foliage, all terminal : middle stem leaves oval, 2/4 

 inches long, 1/4 in width, very obtuse, closely sessile by a 

 deeply cordate-clasping base : flowers small, green : fruit not 

 known. 



Plant said to be common in South Dakota, near Brookings, 

 whence specimens by Thos. A. Williams were obtained, and 

 are in U. S. Herb. 



Apocynum incanum. Leaves elongated-ovate, very acute, 

 short-petiolate, grayish above and much whitened beneath 

 with a fine short tomentum ; flowering branches all near the 

 summit, densely cymose, collectively forming an almost flat- 

 topped compound corymbose inflorescence : sepals lanceolate, 

 acuminate, tomentulose like the pedicels and bractlets : corollas 

 small, erect, with short-cylindric tube and abruptly spreading 

 limb, the lobes narrow, acute, the whole flesh-colored : fruit 

 unknown. 



Almost silky-hoary species, known only from southern 

 Oregon, as collected at Bolt, Jackson Co., July, 1892, by 

 E- W. Hammond. 



The species appears to be of that group, somewhat inter- 

 mediate between the Cannabina and the Androsaemifolia to 

 which A . medium of the East and several others belong. 



The specimens are too fragmentary, consisting of the tops 

 only of the stems; but there is no doubt that they repre- 

 sent a species until now unknown.
