articulated below the middle : bracteoles ovate -roundish ; petals yellow ; pericarp smooth : 

 wing obovate, arcuate-ascending or horizontal : superior margin produced into a basilar del- 

 toid appendage.— Plum. Ed. Burm. t. 14. Cav. Diss. 8. t. 242, 9. t. 243. Bot. Reg. t. 

 937- — Banisteria, L., Sw. B. cserulea, Lam. Heteropteris cserulea, Kth., Juss.!: there is 

 no character to distinguish this : the blue colour of its petals rests merely upon the authority 

 of Plumier, and is probably an old mistake, as the petals are undoubtedly yellow {Si., Mac/.), 

 or a change of colour may perhaps take place with age, as according to the figure of the Bot. 

 Beg. the pedicels are blue, while the petals are yellow.- 1 — A twining climber ; leaves 3"-6' 

 long ; samara; 12"'-20" r long, variable just as in the preceding, the Wing being either con- 

 • stricted at the base, and asceuding in an angle of about 40°, or not constricted and exactly 

 horizontal. — Hab. Jamaica !, Hartw., Al., March, common, among shrubs ; [Cuba ! to

 articulated at the middle : bracteoles minute, deltoid ; petals yellow ; pericarp smooth : wing 

 large, oblong or seuriobovate, straight : superior margin produced above the cell— Juss. 

 Monogr. t. 14 : the samara. — A climber ; samarse 2-j" long, 10'" broad above in the Trinidad 

 form. — Hab. Trinidad!, Or.; [Guiana, New Granada!, equatorial Brazil!]. 



Teibe III. HLRJEACEM— Stamens mostly 10. Styles 3 (-1). Samaroid nuts, with the 

 principal wings lateral, inserted upon a pyramidal torus. 



8. TRIOPTERIS, L. 



Calyx 8-glandular. Stamens all fertile. Styles 3 : stigmas obliquely truncate. Samara 

 with 3 lateral wings : two superior spreading, the third inferior, descending : dorsal line of 

 the pericarp shortly crested. — Glabrous climbers ; panicles lax, constituted of distant ra- 

 cemes ; flowers blue. 



39. T. ovata, Cav. Leaves chartaceous, elliptical-oblong, with 2 minute glands beneath 

 and close to the petiole : veins irregularly reticulated ; samara-wings setniobovate-oblong. ■ 

 Cav. Diss. 9. t. 259. Juss. Monogr. t. 18. — T. jamaicensis, Sw. ! Malpighia paniculata, 

 Mill.! (Bunchosia, DC). Hirsea Jussiaeana, Miq! (exclus. descr. fruct.). — A twining 

 climber ; leaves usually 2"-2g" long ; samara-wings 6"' long. — Hab. Jamaica !, Sw., Macf, 

 Wils., March ; [Haiti; Surinam!]. 



40. T. rigida, Sw.! Leaves rigid, coriaceous, orbicular-obovate, elliptical or oblong- 

 linear, eglandular, lineale with many parallel and anastomosing veins ; samara-wings semi- 

 obovate. — A twining climber ; leaves shining ; samara-wings 5"' long, inferior sometimes 

 shorter. 



a. Leaves broad, retuse or blunt. — Kth. Nov. Gen. 5. t. 451. — T. lucida, Kth. T.^hava- 

 nensis, Kth.— Leaves 1\" long, 16"'-8'" broad. 



£. leaves narrow. — Jacq. Observ. 3. t. 57. — T. jamaicensis, L., Cliff.! (non Sw.). Ba- 

 nisteria microphylla, Jacq. Triopteris parviflora, Juss.! — Leaves 12"'-6''' long, 6"'-3'" broad. 

 Linnseus's name is not to be adopted : for he confounded different plants amoug his syno- 

 nyms, and the species has not been observed in Jamaica ; Swartz's homonym besides be- 

 longs to the preceding species. 



Hab. Bahamas!, Swains. (/3) ; [Cuba!, Haiti!]. 



9. TETRAPTERIS, Cav. 



Calyx usually 8-glandnlar. Stamens all fertile. Styles 3 : stigmas truncate. Samara 

 with 4 lateral wings, 2 of which are superior, 2 inferior : dorsal line of the pericarp crested.
