gameneze, minute crebre striatz,, arcte imbricate, pro spadicis emis- 
sione lacerz, caduez ; omnes spathe pilis brevibus appressis fulves- 
centibus subdeciduis vestita. Spadicis stipes 6-unc., obsolete trigonus, 
fere teres, pro spatharum insertione annulatus, annulo supplementario 
apicali vaginam bilabiatam (quasi spatham rudimentariam) gerente, 
in ramos subocto, confertos, simplices, 6-unciales, preefloratione sinis- 
trorsum circinatos postea subrectos, teretes, minute pannosos, spira- 
liter areolatos, floribus dense obtectos, divisus. Sepala squameformia, 
crassa, rigida, castanea, subpuberula, tuberculis paucis sparsa, sestiva- 
tione valvata ; exteriora 3-5 (plerumque 4), late subulata, obtusiuscula, 
lineam longa, libera vel nonnunquam duo in unicum bifidum coalita ; 
interiora tria, longissima (7 lin.), anguste subulata, subflexuosa. 
Stamina 12-16 (plerumque 13) ; anthere paullo supra basin in fila- 
mento brevi (4-1 lin.) subulato compresso positz, lineares, 4 lin. 
longer, obtuse 4-gonz, 2-loculares, longitudinaliter dehiscentes, pilis 
albidis flexuosis deciduis vestite, connectivo centrali tenui in mecro- 
nem curvulum producto; pollen globosum leve. 
. Spathe iis spadicis d subconformes, ancipites tamen, compressule, 
bilabiatim rumpentes, labiis fissis; 3 interiores, fructibus maturatis, 
caducee vel eorum reliquia sola persistentia. Spadicis stipes subcom- 
pressus, 10-uncialis, adscendens, apice decurvus et ramos 5-7 con- 
fertos, fere verticillatos, rectos, patulos, 8-unciales, diametro (fructibus 
inclusis) fere 4-unciali, proferens. Sepala exteriora tria, a basi præ- 
lata triangulari brevi-subulata, 2-3 lin. longa, inter se subineequalia ; 
interiora tria, late subulata, subflexuosa, 5-6 lin. longa. Ovaria tria, 
ovalia, 33 lin. longa, basi inter se et cum stylo coalita, villosa, 1-locu- 
laria, 1 vel szepius 2 sterilia; ovulum unicum ex baseos angulo interno 
fere erectum, sessile, anatropum. Stylus unicus centralis, 7 lin. longus, 
subulatus, subtrigonus, villosus, plerumque cum ovariis abortivis ad 
ovarii fertilis basin persistens, rarius deciduus; stigmata tria teretia, 
erecto-flexuosa, З lin. longa. Bacce 1-sperme, sicce, in spadice den- 
sissime collecte, pressione mutuá 3-6-angulari-obpyramidate, apice 
lato convexo, pilis cinereis, basi solidis subfasciculatis, superne con- 
tinue tubulosis, flexuosis, villosae. Pericarpium molliter lignosum 
tenuiusculum, apice incrassatum. Endocarpium membranaceur

* Spadices, with ripe fruits, are usually found on the fourth ring below ! 
fronds ; the other three rings (which are at first very close, but become nj 
distant as the trunk lengthens) have spadices in different stages of growth.
