80 DiADELPHIA. DECANDRIA. 



271. AMPHICARPA. Nutt. Gen. 615. 



[Gr . Antphi, both, or about, and Karpos, fruit; producing fruit both above and at the surface of the earth.] 



Cal. 4 toothed. Cor. petals oblong, equal ; banner with the sides appressed. Legume compressed, stipitate. 

 A. MowoicA. Ell Racemes of the stem clustered, mostly sterile; peduncles below apetalous, fertile. 

 Synon. Glycine mouoica. Willd. Mx- Muhl Ph. Vulgo— Wild Bean-vine. 



Fl- Middle of August. Fr. mat. Last of September. 



Hab. Woods, thickets, fence-rows, &c- common. 4, to 6 or 8 feet long: flowers white, or pale purple. 



Obs. This slender vineis mostly found twinin?; round shrubs: the racemes of the stem in pendulous clus- 

 ters, and generally sterile— though I have several specimens bearing short falcate pods, about an inch longy 

 and each for the most part containing three dark purple, or nearly black, compressed, subreniform seeds. 

 The fruit, produced at the surface of the earth, I have not satisfactorily examined. 



A. sARMETiTOSA? Ell. Leaves rhomb-ovate; racemes sub-terminal, filiform; flowers few, incomplete- 



Synon. Glycine sarmentosa? fVilld. Muhl. Ph. 



Fl. Beginning of August. Fr. viat. 



Hab. Woodlands, along Brandywine; C. Brinton's, jr: rare. 2 to4 feet high: flowers white. 



Obs. I have met with this plant but once, in the ^yoods above Brinton's ford, near the forks of the Bran- 

 dywine. The whole plant is pilose — the leaves sprinkled with hairs on both sides, and ciliate on the mar- 

 gms,— rhomboid- ovate in figure, and acute. The racemes filiform, subterminal, and few flowered, (3 to 6) 

 — the flowers small and incomplete, there being no carina; — but there is a partial corolla — viz. banner and 

 wings, — which are spreading and white. The germ is villous— the mature fruit I have not seen. 



b. Legume mostly 1 seeded. 



272. TRIFOLIUM. Nutt. Gen. 604.

Fl. Latter end of May, and after. Fr. mat. July, and after. 



Hab. Pastures: woodlands, &c. common. 6 to 12 inches long; flowers white. 



Obs. It has been doubted, by some, whether this species of clover is a native. If not, it is certainly most 

 comoletely naturalized. Mr. Pursh, who by the way seem?! to have been tinctured with the doctrine of 

 equivocal generation, remarks that this is one of the plants "whose dissemination is really problematical:" 

 -— meanin"-, that it often makes its appearance in situations, and under circumstances, which he could not 

 explain— for Want of facts and observation ! Mr. Elliott says it is eaten but sparingly by stock of any kind; 

 and often produces salivation. In this region, however, it is esteemed as excellent pasture. It if rarely, if 

 ever cultivated artificially; but comes in, as the farmers term it, in good soils which are permitted to repose 

 a few years. Honey-bees are remarkably fond of extracting the nectar from its flowers.

JIab. Gravelly soil: Wilmington road, 4 miles below Dilworthtown: rare. 3to6mcheslong: flowersyellow. 



Obs This humb'e species is believed to be a foreigner; and has not yet extended itself into this immedi- 

 ate vfcinity ■ though it is gradually approaching. Mr. Schweinite, m a note to me, remarks that " it ought 

 to b^ noticed m your publication, on account of the curious steadmess;^of Us peregnna ions. I have been 

 assured by the fa?e Rev. S. Kramsch, that when he came to Salem, N. C about ITOO, no trace of it was 

 ^P^n there It is at this dav (1825,) by far the most common plant in all old fields &c. I myself noticed 

 Us r4''^''^dvJnces deeper into the western country, for 10 years. Here, at Bethlehem, I have nolob- 

 fservedit." ,. ,, ,..,,,
