BAZZANIA, 381 
Folia arcte (ultra } lat.) imbricata, parum decurvula, ovato-cordatove- 
ligulata, insigniter gibboso-faleata, valde inzquilatera, apice 3- (raro 
4-) dentata, dentibus subineequalibus subdivergentibus peracutis, 
sinubus plus minus obtusis, basi antic& caulem vix exacte obtegentia, 
posticé valde rotundato-ampliata ibidemque paucispina, juxta caulem 
seepe 2-3-ciliata, angulo externo haud raro bastatim unispina ; 
ceetero margine undulato-repanda, postico (basi excepta) late incurva ; 
cellulee parvule pellucidé, pariete valde incrassato, trigonis seepe 
dimidiam cellulam excedentibus, guttulate, convexuli, inferiores 
mediz sensim majores subelongatz haud tamen in vittam dispositie. 
Foliola 4 folium excedentia, ovato-oblonga, apice rotundato-truncato 
varia, seepius bis bidentata, dentibus obtusis, acutis, apiculatis 
acuminatisve, basi profunde cordata spinisque paucis armata, inter- 
dum subhastata, juxta caulem sepe utrinque in spinam longam, 
cum spina contraria cruciatam, protracta, ceetero margine repanda 
vel subcrenata. 
Flores dioici. Bracteze 9 erecto-patule, foliis breviores, apice bifidee et 
ciliato-fimbriatz. 
B. robusta 8., ad eundem fluvium Uaupés lecta, differt foliis validis 
multo longioribus—vix autem latioribus—minus abrupte falcatis, basi 
postica minus lata solum eroso-denticulatis ; foliolis (pro foliis) breviori- 
bus, toto margine crenato-repandulis, auriculis baseos suborbiculatis 
integerrimis. 
Duz species, in Andibus Peruvianis lect, a B. spinigera differunt : 
B. acanthostipa 8. foliis magis elongatis, foliolis (pro ratione) minoribus 
quadratis ; 2. B. heteroclada 8. foliis majoribus, foliolis quadrato-oblongis 
basi inermibus.

Folia tenera distiche patula, parum decurvula, basi ad 4 lat. imbricata, 
subfaleata, valde oblique semicordato-ovato-lingulata, apice oblique 
truncato subacute tridentata, dentibus triangularibus apiculatis, basi 
antica caulem transeuntia, postico amplata ibidemque recurvula 4- 
spina, spina infima longiore supra caulem protracta; cellule pel- 
lucidee, trigonis maximis, mediz inferiores elongate lateralibus 
sensim duplo longiores nervum indistincte fingentes. 
Foliola 24plo breviora subcontigua cordato-quadrata, apice rotundato 
truncatove acute 4-crenata, crenulis oblongis rotundatis vel abrupte 
apiculatis, margine utrinque grosse 1—2-dentata, raro imermia, basi 
cordato-biauriculata, auriculis conniventibus imbricatis oblongis 
recurvo-crispis vario modo 2—4-spinis. 
B. spinigera diversa est foliis brevioribus insigniter arcuato-falcatis ; 
foliolis pro ratione multo majoribus, margine laterali integerrimis ; 
B. heteroclada statura humiliore, ramis posticis seepe foliosis ramulosisque, 
neque solum flagelliformibus ; foliis confertis apice longidentatis ; foliolis
