semipollicem circiter longs, erectze, deciduæ. Flores polygami, ex speciosissimis inter congeneres, 
diametro 4-pollicares, quondam in eodem ramo multo minoribus mixti, ad ramulos vetustiores vel 
imo ad truncum ipsum nascentes, plerumque 3 vel 4 fasciculati, pedunculis 1-14 poll. longis colo- 
ratis basi minute bracteolatis suffulti, evolutione successiva aperti. Alabastra globosa, apiculata,

tione late imbricatis, concavis, obtuse carinatis, pollicem longis, semipollice latioribus, extus pube 
minutissima caduca subvelutinis, fusco-rubentibus, demum deciduis. Petala 9-12, plerumque 10 vel 
ll, alba vel albido-rosea, obovato-spathulata, patentia, membranacea; lamina obovata 1-14 poll. 
longa, venulis sursum divergentibus percursa, margine integro obiter undulata, sensim in unguem 
3-1 poll. longum compresso-planum 1 lineam latum attenuata, una cum staminibus decidua. Sta- 
mina numerosissima ; filamenta filiformia, ascendentia, albida, pollicem longa; antheræ terminales, 
intense flavæ, oblongo-lineares, basi subcordatæ, quam filamenta multoties breviora, biloculares, 
longitudinaliter dehiscentes; pollinis granula globoso-ellipsoidea, levia. Ovarium ovoideum, papillis 
acutiusculis undique echinulatum ; ovula juxta placentas parietales 5 vel 6 perplurima; stylus 
rectus, cylindricus, fere pollicem longus, apice radiato 5—6-lobus, demum indurescens, in fructu 
persistens. Capsula matura globosa vel sepius ovoidea, undique aculeis rigidulis 1 pollicem longis 
leete aureo-flavis echinata, tarde dehiscens, 5- vel 6-valvata, valvis crassis, lignoso-duris, demum 
arcuato-recurvis, intus nudiusculis, medio placentiferis. Semina permulta in pulpa nidulantia, par- 
vula, duabus lineis vix longiora, ovoidea, fuscula, crebre verruculosa, vertice truncato areola in centro 
umbonata instructa ; testa crustacea ; embryo rectus ; cotyledones planz, ovatz ; radicula crassiuscula 
cotyledonum fere longitudine, hilo proxima.
