Catalogue ofPlanls groztsing in East-Florida. 291 



Observations, — Scarcely distinct from P. rosea, but 

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

 perhaps a variety. 



Rhamnus minutiflorus. Mich. 



Ceanothus microphylJus. Mich. 



Herniaria * «/V?enca.>ift, procumbens, glabriusculis, foliis 

 lineari oblongis intornodiis multo brevioribus, stipulis rai- 

 nutis, fasciculis, paucifloris, cal, lacisjiis obtusis coarctatis. 

 P. Anychia h^rniaroides, Elliot, not of Michaux. 



Perhaps the supposed Camphorosma glabra ? The 

 stem is clothed with a minute retrorse pubescence. The 

 clusters of flowers contain from about three to five ; the 

 upper and inner part of the calyx is whitish. 



Matelea ? * IcBvis, foliis lanceolatis utriaque acuminatis, 

 umbellis longe pedunculatis, axillaribus, folliculi lasvi tereti. 



Observations. — Stem herbaceous, and terete with an 

 alternating line of pubescence. Leaves opposite, lanceo- 

 late and acuminate, petiolate. Umbels axillary on longish 

 peduncles. Caiix five- parted, segments acuminate. (Co- 

 rolla not seen.) Follicle acuminated at either extremity, 

 smooth and even. Seeds destitute of pappus, (but in other 

 respects resembling those ofAsclepias, elliptic, with a broad- 

 ish membranaceous margin, imbricately attached to a some- 

 what slender unconnected central receptacle. On a care- 

 ful examination of Aublet's figure and descriptiou of mate- 

 lea, I am fully satisfied that it is a congener of the present 

 plant, although we are yet unacquainted with the corolla of 

 this species. The anthers, as they were then considered, 

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

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

 tion, similar to those of Asclepias and Cynanchum, to which 

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

 ted by Mr. Ware, might from its whole habit be readily ta- 

 ken for an Asclepias. 



Cynanchum * scoparium, denudatum; caule volubili 

 perenne, foliis liearibus remotis, umbellis subsessilibus 

 parvifloris. 



Observation. — Stem green and perennial, striated, and 

 with the exception of the recent branches Jiaked ; branch- 

 es opposite, furnished with an alternating pubescent line.
