Palmier Tucubiba-iyi, d'Oib., n." 24, ciiin icône. (Specimina nulla suppetunt, quare e

Caiidices pleiumque 4 avit 5 cœspitoso-congesti, 18 — 20 pedes alti, recli, cylindrici, 

 diametro 3 — 4-pollicari, epidermide grisea, insculpli aniiulis subregularibus in infe- 

 riore parle remotis in supeiiore approximalis , inter annulos aimati aculeis subulatis 

 nigricantibus quaquaversus diieclis, e tuberculo parvo orlis, 3 — 4 poil, longis. 



Frondes 6 — 7 pedes longse; nonnulke siccalfe de caudice dependentes, leliquœ (5 — 8) 

 virides, ereclo-patenles et patentes. Vagina brevis in pctiolum abiens infia oonvexulum 

 supra leviter concavum , uli rhachis aculeis longis nigricantibus armata. Pinnœ in 

 quovis rhacbeos latere ad 100 usque, ternae, quaternse aut c^uinee dispositse in greges 

 subirregulariter alternantes, rigidœ, saturate virides, lineari - lanceolalœ , acuminalse, 

 margine munitœ selulis tandem dilabenlibus, nervo medio supra prominulo el passim 

 aculeato percursœ , sesquipedem longse , 2 centim. latse. Directio pinnarum haud regu- 

 laris, ita ut liabitus comae subcrispatus. 



Delapsis frondibus apparent Spalhœ plerumque 2, 3 vel 4, obovato-fusiformes , 

 densissime horridœ aculeis, intus glaberrimae. Spadix ramosus, pedem longus , dense 

 floribus obteclus, quorum masculi plures sunt et versus extremitales ramorum fre-

Hsec species inter congénères Bactridi setosœ videtur prœ aliis affinis, attamen diversa 

 aculeis nigris, nec fuscis aut expallidis, caudice rectiore, aculeis crebrioribus raajori- 

 bus per internodia armato , drupa majore flava nec purpureo-nigricante. Ulteriora 

 innotescent, dum stirpis specimina examinandi data fuerit occasio. 



Crescit in sylvarum locis uliginosis in regione Indorum Guarayos, e. g. prope vicum
