Observations. — Scarcely distinct from P. rosea, but 

 bearing white flowers like P. scandens^ of which it may be 

 perhaps a variety.

 P- An^chia herniaroides^ ElJiot, not of Michaux. 



Perhaps the supposed Camphorosma glabra 9 The 

 stem is clothed with a minute retrorse pubescence. Th 

 clusters of flowers contain from about three to five ; the 

 upper and inner part of th' calyx is wliitish.

Obskrvations. — Stem herbaceous, and terete with^ an 

 alternating line of pubescence. Leaves opposite, la c o- 

 late and acuminate, petiolate. Umbels axillary on loagish 

 peduncles. Ca^ix five parted, segments acuavinatep (Co- 

 rolla not seen.) Follicle acuminated at either extremity, 

 smooth and even. Seeds destitute ofpapp.:^s. (but in otl]er

?^«, I am fully satisfied that it is a. congener of ?he p* i 

 plant, although we are yet unacquainted with the coroHn of 

 this species. The anthers, as they were then consici^. J, 

 though so singularly described by Persoon, (Synopis, 1. p. 

 276,) are evidently on the authority of Aublet's descrip- 

 ^00, similar to those of Asclepias and Cynanchum, to which 

 the genus holds a near affinity. The specimen albo collec-

ken for an Asclepias. 



Cynanchum * scoparium^ dcnudatum; caule volubili 

 perenne, foliis liearibus remotis, umbellis subsessilibus

OBSERVATIo^^ — Stem green and perennial, striated, and 

 ^ith the exception of the recent branches naked ; branch- 

 es opposite, furnished with an alternating pubescent line.
