hemispheres,— and is usually restricted to the vicinity of salt water; tut I have a 

 Kentucky specimen form Prof. Short. It is the only known species of the genus.

 Pursh, Torrey, Meek, &c. is probably a Sytionym of tins.

 stolones of this species, become rathe?' thick and coriaceous in the 

 latter part of the season.

 {Greek, Gonia, an angle, and Lobos, a pod ; from its ribbed or angular follicles.] 



Calyx much smaller than the corolla, 5-parted. Corolla rotate, deep- 

 ly 5-parted. Lepanthium scutellate, 5-lobed, equalling the antheridi- 

 um. Antheridium depressed, discoid, pentangular, without either 

 winged angles, or scarious cusps. Pollinia 5 pairs, transverse. Fol-

1. G. macropiiylltjs, Mx? Leaves roundish-cordate with the sinus 

 nearly closed, abruptly acuminate ; follicles muricatc ; lobes of the 

 lepanthium divided. Ell ? Sk. 1. p. 327.

Long, or large-leaved Gonolobus. 



Root perennial. Stem several feet long, slender, hirsutely pubescent, twining 

 and climbing over shrubs. Leaves 3 to 5 inches long, and often nearly as wide as 

 long, orbicular-cordate, with a short abrupt acumination, entire, of a thinnish tex- 

 ture, finely pubescent, especially beneath and on the margin, pilose on the nerves; 

 petioles 1 to 2 inches long, hirsute with spreading hairs. Flowers in loose cymose 

 umbels, on axillary common peduncles 1 or 2 to 4 inches in length. Calyx small ; 

 segments linear-lanceolate, hirsute. Corolla deeply 5-parted ; lobes about half an 

 inch long, linear-oblong, rather obtuse, greenish and pubescent externally, of a 

 dark dingy-purple on the inner surface. 



Hab. Chesnut hill, near Pughtown: rare. Fl. Fr. 



Obs. Found in the above locality, in Aug. 1836, by Mr, Joseph Rinbhart, who 

 collected a specimen without flowers. The leaves are more orbicular, and with a 

 shorter acumination, than in my specimens from the South and West; but Mr. 

 Nuttall unhesitatingly pronounced our plant to be G. macrophylltia. I suspect, 

 however, it must be the same with that described as G. obliquus, by Dr. Torrey— 

 and given on the authority of Z. Collins, Esq. as " certainly indigenous near the 

 falls of the Schuylkill." See Tort. Fl. 1. p. 278. Three or 4 additional species are 

 enumerated in the U, States.
