quo recedit trunco magis elato, foliorum pinnis firmioribus pro longitudine 
latioribus plerumque supra spinis marginalibus longius attenuatis, praeser-

spinescentibus ad 24 cm. longis 1°5-2°5 cm. latis utrinsecus spinis 4-1 
(saepissime 8-2) armatis, spina summa plerumque ab apice remota, rigide 
coriaceis glaberrimis obscure parallele nervosis, pinnis inferioribus per-

The stately Cycad here described and figured was first, 
discovered by Sir John Kirk near Dar-es-Salam on the 
East African Coast in 1868. The material originally 
sent home consisted of some pinnae and a few seeds and 
proved too incomplete for description. Two years later 
he made the first attempt to introduce the plant to 
European cultivation, but the stem which he sent home 
January, 1915.
