 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 ; f ructibus 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 

 the apex, shortly apiculate.
