Squamas strobili masculi axi perpendiculares, confertae, obovato-cu- 

 neata?, subtus medium usgue loculigerae, apice latiore truncato et dia- 

 metro transverso longiore hexagono. Squamas strobili feminei (ex F. 



Muell.) deltoideo-rhombese, peltatae, crassae, angulis peltaa , sti- 



pite longo. Semina ovato-globosa. — Arbuscula bumiljs, Novse Hol- 

 landiee; foliis bipinnatisectis, segmentis primariis paucis, inferioribus 

 ternatis quinatisve, aliis oppositis, secundariis parallele multinerviis. 

 — An genus servandum? Vix dicerem si fiores masc. et fem. vere iis 

 Encephalartos similes, ut affirmavit cl, F. Mueller, nam divisio limbi 

 foliorum variare videmus in generibus admodum naturalibus, ut 

 Clematis, Ranunculus, Aralia, Begonia , Manihot, etc. Adsunt t-a- 

 men queadam diversa m fiore masculo, ex squamis adpressis clineatis, 

 pelta hexagona; peltae femineorum non sufficienter sunt cqgnit», semen 

 non dicitur costatum, et putamen forsan aliter crescit, quibus causis ge- 

 nus provisorie admisi.
