The alliance of this species is manifestly with Pipturus argen- 

 teus Wedd., from which it is readily distinguishable by its un- 

 usually narrow, lanceolate leaves. 



POLYCHROA Loureiro 

 (Pellionia Gaudichaud) 

 POLYCHROA MULTINERVIA sp. nov. 



Suffruticosa, erecta vel subscandens, usque ad 50 cm alta, par- 

 tibus junioribus et subtus foliis f errugineo-pubescentibus ; 

 foliis membranaceis, lanceolatis, aequilateralibus, 15 ad 20 cm 

 longis, tenuiter acuminatis, basi obtusis, margine grosse et 

 regulariter dentatis, nervis utrinque circiter 30, perspicuis; 

 cymis axillaribus, parvis, circiter 1 cm diametro; floribus $ 

 5-meris, sepalis omnibus corniculatis, sub anthesin 3 mm longis, 

 accrescentibus et sub fructu 6 mm longis, partibus inferioribus 

 ellipticis; staminoideis sub fructu valde incrassatis. 



An erect or somewhat scandent simple suff rutescent plant 

 up to 50 cm high, the younger parts and the nerves and midribs 

 on the lower surface of the leaves distinctly ferruginous-pubes- 

 cent. Stems somewhat woody, terete, brown when dry, 2 to 

 2.5 mm in diameter, the younger parts somewhat sulcate or 

 angled. Leaves membranaceous, lanceolate, 15 to 20 cm long, 

 2.5 to 4 cm wide, equilateral, the base usually obtuse, gradually 

 narrowed upward to the slenderly acuminate apex, the margins 

 coarsely dentate except at the very base, the teeth 5 to 8 mm 

 apart, the upper surface olivaceous, shining, glabrous, smooth, 

 minutely and densely pitted, the pits very shallow, cystoliths 

 entirely wanting; lateral nerves about 30 on each side of the 

 midrib, very distinct on the lower surface, the reticulations 

 lax; petioles ferruginous-pubescent, 5 to 8 mm long; stipules 

 lanceolate, acuminate, glabrous, brown, about 1 cm long. Cymes 

 axillary, solitary, rather dense, about 1 cm in diameter, their 

 peduncles up to 5 mm long, the pedicels less than 1 mm long. 

 Female flowers, in anthesis, 3 mm long, green. Sepals 5, the 

 basal part elliptic, about 1 mm long, somewhat cucullate, all 

 spurred from the back, the spurs slender, about 2 mm long. The 

 sepals in fruit accrescent and including the spur up to 6 mm 

 in length, the spur obscurely ciliate. Staminodes in fruit much 

 thickened, obovate, somewhat 4-angled, truncate, about 1 mm 

 long, and 0.8 mm wide. Achene elliptic-ovate, somewhat com- 

 pressed, about 2 mm long.
