DIDYNAMIA ANGIOSPERMIA. 
Root annual. Stem firmly erect, 3- — 5 feet high, marked with lines de- 
current from the leaves, very scabrous. Leaves linear, acute, producing 
in each axil, small branchlets, with 8 or 10 small leaves, these towards the 
summit of the stem, become real branches. The Leaves and Flowers 
near the summit of the branches are sometimes alternate, but this is evi- 
dently accidental. The Peduncles are very short, rarely exceeding 2 lines in 
length. Calyx truncate, the teeth subulate, acute, longer than any other 
species in this division. Corolla as large as that of G. Purpurea., bright 
purple, hairy along the side of the tube, marked with 2 yellow streaks, 
spotted with red, the border equally 5-cleft, the two upper segments emargi- 
nate, reflexed and very villous, 3 lower pubescent and fringed. Filaments 
very villous, the 2 longer as long as the tube of the corolla. Style longer 
than the corolla. Stigma obtuse. Seeds very numerous and small, attach- 
ed to a central receptacle. 
Grows principally in lands subject to occasional inundation from the 
ocean — on E ding’s Island near Beaufort very common. 
Flowers August — October.

Stem terete, branch- 
ing ; leaves filiform, 
somewhat clustered, 
glabrous, alternate ; 
segments of the calyx 
acutely toothed ; pe- 
duncles longer than 
the leaves. 
Leaves filiform, about an inch long, nearly terete, smooth and very slen 
der, collected in axillary clusters. Flowers purple, as large as those of G. 
Purpurea. Orifice of the Corolla pubescent and ventricose. Peduncles 
nearly an inch and a half long. Nuttall. 
This species has a close affinity to the preceding, but its smooth leaves 
and long peduncle render it sufficiently distinct. The leaves perhaps 
are only accidentally as in the preceding species alternate. 
Found by Dr. Baldwin near St. Mary’s and along the coast of E. Flo- 
rida. 
Flowers probably from August to October.
