dissitae, et in dentes marginales alternis vicibus excurrentes, subtus 

 prominulse costseformes, interspatiis plica percursis. 



Flores monoici, in diversis spadicibus, plerumque tribus (sc. unico ? , 

 caeteris duobus i ), ex eodem verticillo ortis*. 



S . Spathee 6 : 3 exteriores cuneata?, vaginaeformes, subtrigonae, 4-unci- 

 ales, primitus clausae, apiculatae, dein apice irregulariter ruptae, imbri- 

 catae, persistentes ; 3 interiores raajores, llx3-unc., e basi angustata 

 stipitiformi fusiformes, apiculo brevi compresso obtuso recurvo, per- 

 gameneae, minute crebre striatae, arete imbricatae, pro spadicis emis- 

 sione lacerae, cadueae ; omnes spathae pilis brevibus appressis fulves- 

 centibus subdeciduis vestitae. Spadicis stipes 6-une., obsolete trigonus, 

 fere teres, pro spatharum insertione annulatus, annulo supplementario 

 apicali vaginam bilabiatam (quasi spatham rudimentariam) gerente, 

 in ramos subocto, eonfertos, simpliees, 6-uneiales, praefloratione sinis- 

 trorsum circinatos postea subrectos, teretes, minute pannosos, spira- 

 liter areolatos, floribus dense obteetos, divisus. Sepala squamaeforraia, 

 crassa, rigida, eastanea, subpuberula, tubereulis paucis sparsa, aestiva- 

 tione valvata ; exteriora 3-5 (plerumque 4), late subulata, obtusiuscula, 

 lineam longa, libera vel nonnunquam duo in unicum bifidum coalita ; 

 interior a tria, longissima (7 lin.), anguste subulata, subflexuosa. 

 Stamina 12-16 (plerumque 13) ; anther cb pauUo supra basin in jila- 

 mento brevi (i-1 lin.) subulate compresso positae, lineares, 4 lin. 

 longae, obtuse 4-gonae, 2-loculares, longitudinaliter dehiscentes, pilis 

 albidis flexuosis deciduis vestitae, connective centrali tenui in mucro- 

 nem curvulum producto ; pollen globosum laeve. 



? . Spathee iis spadicis <? subconformes, ancipites tamen, compressulae, 

 bilabiatim rumpentes, labiis fissis ; 3 interiores, fructibus maturatis, 

 cadueae vel eorum reliquia sola persistentia. Spadicis stipes subcom- 

 pressus, 10-uncialis, adscendens, apice decurvus et ramos 5-7 eon- 

 fertos, fere verticillatos, rectos, patulos, 8-unciales, diametro (fructibus 

 inclusis) fere 4-unciali, proferens. Sepala exteriora tria, a basi prae- 

 lata triangulari brevi-subulata, 2-3 lin. longa, inter se subinaequalia ; 

 interiora tria, late subulata, subflexuosa, 5-6 lin. longa. Ovaria tria, 

 ovalia, 3i lin. longa, basi inter se et cum stylo coalita, villosa, 1-locu- 

 laria, 1 vel saepius 2 sterilia ; ovulum unicum ex baseos angulo intemo 

 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, 3 lin. longa. Baccce 1-spermae, siccae, in spadice den- 

 sissime collectae, pressione mutua 3-6-angulari-obpyramidatae, apice 

 lato convexo, pilis cinereis, basi solidis subfasciculatis, superne con- 

 tinue tubulosis, flexuosis, villosae. Pericarpium molliter lignosum, 

 tenuiu senium, apice incrassatum. Endocarpium membranaceum, 



* Spadices, with ripe fruits, are usually found on the fourth ring below tlie 

 fronds ; the other three rings (which are at first very close, but become more 

 distant as the trunk lengthens) have spadices in different stages of growth.
