116 DIDYNAMIA ANGIOSrERMlA, 



* 



Root annual. Stem firmly erect, 3—5 feet high, marked with Uuesde^ 

 current from the leaves^ very scabrous. Leaves Unear^ acute^ producing 

 in each axil^ small branchlets^ witli 8 or 10 small leaves, these towards the 

 summit of the stem, become real branches. The Leaver m\d Flowers 

 near the summit of the branches are sometunes alternate, but this is evi- 

 dently accidental. The Pedunc^'^s are very short, rarely exceeding 2 lines in 

 length. Cali/x truncate, the teeth subulate, acute, longer than any other 

 species in this division. CGrolla 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- 

 Tiate, refiexed and very villous, 3 lower pubescent and fringed- Filaments 

 very villous, the 2 longer as long as the tube of the corolla. Sti/Ie 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 Eding^s Island near Beaufort very common, 

 flowers August — October. ■

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 

 nearlv a?i inch and a half lonfj. Nuttalt^ 



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 accideutally as in. the preceding species alternate.
