VENTILAGO Gaertner 
VENTILAGO LANCEOLATA sp. nov. 
Frutex scandens, partibus junioribus exceptis glaber; ramulis 
tenuibus, teretibus; foliis lanceolatis, chartaceis, integris, usque 
ad 8 cm longis, brevissime petiolatis, sursum angustatis, obtusis, 
basi subacutis ad subrotundatis, nervis utrinque circiter 9, tenui- 
bus; racemis axillaribus, tenuibus, sub fructu usque ad 6 cm 
longis, solitariis; fructibus 4 ad 5 cm longis. 
A scandent shrub, glabrous except the younger parts. 
Branches slender, terete, the branchlets glabrous or slightly and 
obscurely pubescent. Leaves lanceolate, chartaceous, 5 to 8 cm 
long, 1 to 2.5 cm wide, rather pale when dry, shining on both 
surfaces, entire, gradually narrowed upward to the obtuse apex, 
the base subacute to subobtuse; lateral nerves about 9 on each 
side of the midrib, very slender, curved-ascending, obscurely 
anastomosing very close to the margins, the reticulations fine, 
close, evident on both surfaces; petioles glabrous, 2 mm long 
or less. Racemes axillary, solitary, slender, in fruit up to 6 
cm long, slightly pubescent. Fruits, including the wing, 4 to 5 
cm long, the basal part nearly 5 mm in diameter, quite glabrous, 
the wing 7.5 to 10 mm wide, reticulate, somewhat rounded at
