tinct sp. stem iiedal, leaves small seliiiuncial, 

 peduncles uncial, corolla nearly entire, stamens 

 subequal, styles deeper cut, stigmas really glo- 

 bose. Evidently not the C. tenellus of Elliot. 



870. Stylisma elliptica Raf. stem twining 

 terete pilose, leaves petiolate elliptical hardly 

 pubescent, base subcordate, end obtuse mucro- 

 nate, peduncles uniflore subequal to leaves with 

 two minute bracts, calix smooth, segments ovate 

 acuminate, capsule hirsute — sent me from Ala- 

 bama and Georgia, traihng or twining for 2 or 

 3 feet, leaves uncial, style bifid, 2 globose stig- 

 mas. My Styl. sherardi, Convolv. do Pursh. 

 Elliot, a doubtful plant differs from this by leaves 

 retuse and sessile flow^ers. 



871. Stylisma peduncularis Raf. Convolv. 

 tenellus Lin ? Elliot Slc stem flexuose pilose, 

 leaves subpetiolate elliptical obtuse mucronate 

 ciliolate, base subcordate, peduncles elongate 2 

 or 3 times the length of leaves 2 or Sflore, calix 

 smooth, segments ovate acuminate bracts mi- 

 nute, capsule bearded — Alabama and Florida, 

 near the last but larger leaves, stiff long pedun- 

 cles, style deeply divided, stigmas obtuse. The 

 Conv. tenellus of Elliot only differs from my 

 specimens by peduncles 3-5flore, calix ciliate 

 <^c. — But his C. trichosanthes my ^tylisma do, 

 differs much being quite tomentose &c. 



Having obtained both the Evolvulus sericeus 

 of Cuba collected by Jalambic and that of Flo- 

 rida from Baldwin ; they appear alike, except 

 that the stem is nearly smooth in the Cuban 

 specimen, pilose in the Floridan.

 gular subbilabiate, lips 2 and Slobed, Stamens
