RHAMNACEAE 



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 

 the apex, shortly apiculate.

Arbor circiter 5 m alta, ramulis pubescentibus, spinosis ; foliis 

 parvis, suboblique ellipticis vel elliptico-ovatis, chartaceis, usque 

 ad 3 cm longis, obtusis, 3-nerviis, subtus parce pubescentibus; 

 fructibus globosis, glabris, 1.5 cm diametro. 



A tree about 5 m high, the branches terete, reddish-brown, 

 glabrous, the branchlets with very short sharp spines at the 

 nodes 1 to 2 mm in length, the younger branchlets ferruginous-
