conveniently take the name of Dicfyolohus, using here the Greek word 

 in the sense of lobe, instead of pod. 



The North American Gonolobi, of the Atlantic United States, are 

 confused and dilfitnilt, partly because flower and fruit have seldom 

 been had from the same plant. The subjoined conspectus gives the 

 result of my study of the present available materials, aided by notes 

 and sketches from Dr. Enoelmanu. * 



* GONOLOBUS, Michx. Fl. i. 119. 



§ 1. DiCTTOLOBUS. Corolla rete subtili conspicuo saepius colorato venosissima, 

 nunc rugulosa ; lobis plerumque hitis. ilores in nostra parvuli, in pleris 

 majusculi. 



G. RETicuLATUs, Engelm. Mss. G. qramtJntna, Torr. Bot. Mex. Bound. 165, 

 non Scheele in Linnsa. — Texas and adjacent borders of Mexico. Well described 

 (except as to antlier-tips, which really overlie the edges of tlie stigma), but 

 wrongly referred, by Dr. Torrey. Scheele's description of the peduncles as 

 shorter than the petiole, the pedicels as barely equalling the flowers, and the 

 lobes of the corolla as lancei)late-attenuate from a broader base, is incompatible 

 with the present species, and relates to a variety of G. Items, Michx. 



§2. EcGONOLOBUs. Corolla baud reticulata, lobis angustioribus : corona sim- 

 plex, intus inappendiculata, columnae basi sspius iuserta : stigmatis anguli 

 parura prominuli : caules herbacei. 



* Pedunculi pauci-pluriflori : corolla 5 partita, rotata, patentissima, 



••- Crassiuscula, viridula, extus cum calyce pedunculo brevi pedicellisque gla- 

 bra : corona sub gynosteraio pateriformis undulatocrenata, carnosa : antherae 

 membrana tenuiter scariosa super marginem stigmatis inflexa : folliculi laeves 

 5-angulati.

 excl. syn. Gronov. Periplocn Carnllnensis, etc., Dill. Elth. 300, t. 229, f. 296. G. 

 macroplii/llus, Chapm Fl. 368. Corolla in alabastro late conica, lobis ovato-trian- 

 gularibus a basi sensim angustioribus acuminatis supra albido-hirsutulis nunc 

 glabratis. — Although Hermann's Brazilian plant, referred to, suggested the 

 name, we may consider the Linnaean species as founded on the Dillenian plant, 

 the figure of which very well represents what we take for this species. More- 

 over tlie Grouovian synonym belongs to G. hirsidns or G. Camfinensis. De- 

 caisne's G. siiber<>s>is, with ovate pubescent sepals, and corolla glabrous within, 

 must be some quite other species. 



G. l;evis, JMiclix. Fl. i. 119. Minus pilosus vel glahellus ; nmbellis 5-10-floris 

 petiolo vix aequilongis: foliis oblongo-cordatis ; corolla in alabastro elongato- 

 conica, lobis lanceolatis sen lineari-lanceolatis glabris ; folliculis laevibus 5-angu. 

 latis. — Mississippi to Arkansas and Texas. Pursh introduces some confusion 

 by adding a wrong synonym, and a consequent misstatement of the color of the 

 corolla. It passes freely into
