I. Quamoclit, L. (Cypress- Vise.) Slender: leaves pinnately parted into linear-filiform

 the tube clavate ; limb obscurely lobed, half to two-thirds inch wide : sepals mostly with 

 slender appendage below the tip. — Sims, Bot. Mag. t. 221 ; Andr. Bot. Rep. t. 400. /. luteola, 

 Jacq. Ic. Rar. t. 35, with orange-colored corolla. Quamoclit coccinea, Mcench, Mcth. 453 ; 

 Choisy in DC. — River-banks, &c, Middle and S. Atlantic States (apparently introduced,
