Paullinia triantennata Silveira in Arch. Jard. Bot. Rio de Janeiro V. (1930) 223. — 

 »Scandens fruticosa pilosa gigantea; rami subteretes, lenticellosi, pilosi; petiolus 

 pilosus, folia ternata; foliola elliptica, apice acuta vel subacuminata, basi acuta, serrato- 

 dentata, foliola lateralia breviter petiolulata, foliolum medianum petiolulatum, rigidius- 

 cula coriacea, reticulato-venosa, pilosa, glandulis microscopicis adspersa; thyrsi 

 solitarii, dense cincinnigeri, pilosi; flores sat robusti sepalis subcoriaceis, 3 et 5 omnino 

 connatis, Capsula globoidea apice trialata, pedunculata ellipsoidea, alis arcualibus 

 transverse oblongis divaricato-patentibus, rigidis.<< 



>>Desta seccäo so se conheciam duas especies; 1) P. neuroptera Radlk. e P. vesper- 

 tilio Swartz, mas a P. triantennata se distingue perfeitamente de ambas. Da primeira 

 se separa perfeitamente pela pillosidade, pelos foliolos dotados de peciolo, principalmente 

 o central, pelos recortes da linha marginal dos foliolos e pelas azas rigidas dos fructos. 

 Da segunda se distingue pelo numero de foliolos, pois possue tres emquanto que P. ves- 

 pertilio Swartz tem 5, pela forma de limbo e pela forma globoide da Capsula. <<

Paullinia Hitchcockii Gleason in Bull. Torrey Bot. Club LIV. (1927) 614. — »Stern 

 nearly terete, very finely puberulent, rufescent; leaf-rhachis angled or channeled, 

 puberulent; leaflets 5, their blades subcoriaceous, somewhat shining above, obovate, 

 the lower 35 — 50 mm wide, 65 — 100 mm long, the uppermost 55 — 75 mm wide, 110 — 

 150 mm long, all abruptly acuminate into an oblong blunt cusp nearly 1 cm long, 

 conspicuously sinuate-dentate along the distal half, long-cuneate (terminal leaflet) to 

 short-cuneate or obtuse (lateral leaflets) at base, glabrous above or minutely puberulent 

 on the midvein, sparsely pubescent beneath; lateral veins about 8 pairs, almost straight, 

 the veinlets elevated on both sides and conspicuously reticulate; flowers lacking; spikes 

 5 — 12 cm long, Single in the axils; fruit red-brown, ellipsoid, 12 mm long, 7 mm in 

 diameter, tri-alate above the middle, the surface and the wings conspicuously veiny.<< 



In Guiana anglica: Hitchcock n. 17120 (Penal Settlement, Dec. 1919). »Here 

 are referred also La Cruz n.l617 (near Wismar), La Cruz n.l725 (Dadanawa) and 

 La Cruz n. 3916 (W^anama River, Northwest District).<< 



>>P. Hitchcockii may be distinguished at a glance from P. rufescens by its leaf 

 characters, especially the obovate leaflets, the conspicuous terminal cusp, the prominent 

 dentation, an^ the cuneate bases. The pubescence is of the same morphological character, 

 but in P. Hitchcockii the hairs of the lower surface average 0,03 — 0,05 mm long and 

 stand 0,10 — 0,15 mm apart, while in P. rufescens they are 0,05 — 0,10 mm long and 

 stand only 0,03 — 0,05 mm apart. The fruit-wings of the latter species are decurrent 

 nearly or quite to the base, while in P. Hitchcockii the basal portion of the fruit is 

 quite wingless.<< 



Paullinia arenicola Gleason in Bull. Torrey Bot. Club LIV. (1927) 615. — »A vine 

 4 m long; the finely striate stem minutely puberulent; leaf-rhachis prominently angled 

 or channeled, minutely puberulent; leaflets 5, subcoriaceous, duU green or somewhat 

 shining, narrowly oblong-elliptic or oblong-lanceolate, 8 — 10 cm long, 30—38 mm wide,
