A tree, 30-70 ft., branchlets woody. Leaves 6-12 in., base contracted rounded 

 or subcordate, above glabrous except sometimes the midrib, beneath more or less 

 rusty-tomentose ; nerves 15-20 pair, crosa-nervules impressed above, much raised 

 beneath ; petiole ^ to in. ; stipules subulate. Male spikes 3-5 in., very stout and 

 as well as the flowers densely brown velvety ; flowers shorter than the bracts, solitary 

 or clustered, sessile or shortly stoutly pedicelied, globose in bud, expanded about in. 

 diam. ; sepals broadly elliptic or oblong, leathery, glabrous within; stamens 100 or 

 more, contorted in bud, glabrous. Clusters of fern. fl. $ in. diam., covered with 

 lanceolate velvety bracts like those of the male ; sepals about in. long. Fruit 

 1-1^ in. diam. ; pericarp thin except at the thick wavy close-set ridges ; endocarp 

 thin. Seeds immature. I refer this with little hesitation to Miquel's Ptychopyms, of 

 which its author had very imperfect specimens. It agrees in the foliage with his 

 description and with a slight sketch made by Professor Oliver from the type speci- 

 men lent to Kew from Leyden, when the Tlliaceoe, (to which the genus was doubtfully 

 referred by Miquel) were being examined for the ' Genera Plantarum."
