 et molliter barbato-papillosis, papillae elongatae, stellato-tomen- 

 tosae; foliis alternis, longe petiolatis, late ovatis, usque ad 

 36 cm longis, basi rotundatis, alte peltatis, apice perspicue 

 caudato-acuminatis, margine irregulariter dentatis vel subin- 

 tegris, subtus densissime griseo- ad ferrugineo-tomentosis ; 

 inflorescentiis S circiter 20 cm longis, parce ramosis, floribus 

 pedicellatis, 5 pedunculatis, spiciformibus, densis, cylindra- 

 ceis, 1 ad 1.5 cm diametro, floribus sessilibus; infructescentiis 

 densis, cylindraceis, circiter 10 cm longis et 3.5 ad 4 cm dia- 

 metro, capsulis echinis mollibus incurvis subulato-filiformibus 

 stellato-tomentosis densissime obtectis. 



A dioecious shrub up to 7 m in height, prominently stellate- 

 tomentose. Branches terete, rather stout, 5 to 10 mm in diam- 

 eter, the leaf-bearing parts densely covered with pale-brown- 

 ish, soft, stout, densely stellate-tomentose papillae about 5 mm 

 in length, the younger petioles often with similar papillae. 

 Leaves alternate, broadly ovate, long-petioled, chartaceous, 13 

 to 36 cm long, 10 to 25 cm wide, the base broadly rounded 

 and peltate, the petiole inserted 1.5 to 5 cm from the margin, 

 the apex prominently caudate-acuminate, the margins suben- 

 tire to irregularly dentate, the teeth never large, usually mi- 

 nute, the upper surface eventually glabrous, or the nerves 

 somewhat stellate-tomentose, pale-olivaceous or brownish-oliva- 

 ceous, the lower surface very densely stellate-tomentose with 

 grayish to subferruginous, short hairs; petioles up to 18 cm 

 in length, those of the smaller leaves very much shorter, some- 

 times but 3 to 4 cm in length, uniformly and densely stellate- 

 tomentose, the younger ones with projecting stellate-tonientose 

 papillae. Staminate inflorescences about 20 cm long, densely 

 stellate-tomentose, sparingly branched, the branches 3 cm long 

 or less. Pedicels about 3 mm long. Sepals 4, oblong-elliptic, 

 2.5 mm long. Stamens about 70, their filaments 2 mm long. 

 Pistillate inflorescences solitary, simple, peduncled, the flower- 

 bearing part dense, cylindric, spiciform, 4 to 5 cm long, 1 to 

 1.5 cm in diameter, the peduncles densely stellate-tomentose 

 and often papillose. Calyx-lobes lanceolate, acuminate, 3 mm
