ticellis flavidis concavis verruculosis; ramulis fuscioribus tenuioribus, subangulatis,

tusis e£ in acumen brevissimum subaeutum naviculari-recurvum repente constrictis, 
integris, margine cartilagineo subundulatis, coriaceis, glaberrimis, nervis utrinque 
circa 15 patentim divaricatis in margine arcuatim nexis, venis transversim reti- 
culatis utraque facie prominentibus, supra viridibus, subtus pallidiusculis, opacis, 
minutissime granulosis; petiolo crassiusculo, supra suleato, subtus ruguloso, limbo 
20-plo breviore: paniculis in ramulis brevibus alaribus axillaribus aut terminalibus, 
binis aut a basi subternis, folio multoties brevioribus, alternatim ramosis, vel in 
axillis annotinis efoliaceis fasciculatim ramosis et multiramulosis, ramulis cre- 
berrime approximatis, alternis aut dichotome divisis cum ramulo breviore in dicho- 
tomiis, valde compressis, rubiginoso-tomentellis; bracteolis alternis acute ovatis, 
divaricatis, denticulatis; floribus majusculis, pedicellatis ; sepalis rotundatis, crassis, 
margine membranaceis, patentibus; petalis triplo longioribus, late ovatis, crassis, 
glabris, marginibus anguste membranaceis et eroso-denticulatis, rotatis; disco ma- 
jusculo, carnoso, conice pulvinato, basi valde et latiuscule expanso, granulatim 
ruguloso; staminibus longe exsertis, demum reflexis; antheris valde membranaceis, 
lobis divaricatis; ovario subtrigonoideo, depresse conico, intra discum occulto; stylo 
subulato, paulo exserto. In Guiana: v. s. in herb. Hook., Surinam (Hostmann, 232). 
In the older branches the axils are remote; but in the younger and more slender 
branchlets they are approximated, being only 3 or 4 lines apart, and opposite: the leaves 
are 8 inches long, 4i in. broad, on a petiole 5 lines long; the panicles are crowded 
towards the ends of the short alary branchlets, and are 14-14 in. long, the peduncles 
being 4-9 lines long, subangular, rufously and scabridly tomentose on the angles: the 
flower expanded is 5 lines in diameter; the sepals and petals are of a dark fuscous 
colour, opaque, with narrow reddish margins in the dried state; the disk is 12 line in 
diameter; the anther-lobes are small, and greatly divaricated at their base.
