Ramus albo-corticatus, 4 mm. cliam. Folia 10-13 X 6-6*7 cm., 

 margine pauUo revoluta ; petioli 3 cm. long, Spica 28-5 cm. long. ; 

 hujus axis interne 2 mm., superne l-*5 mm. crass. ; pars florifera 

 verisimiliter 10 cm. long., exemplarii unici nobis obvii ob flores 

 delapsos modo 3 cm. Bracteae '65 mm. long. Calyx 1 mm. alt., 

 2-.3 mm. diam. Corolla saltem in siccofusca, 5 mm. long. Filamenta 

 1*3 mm., antherse fere 3 mm. long. Kudimentum $ oblongo-ovoideum, 

 sursum attenuatum, apice obtusum, 2'75 mm. long. 



Distinguished easily from *S'. Zenkeri Engl, by the leaves, the 

 long spikes; ampler nearly glabrous calyx, stamens with shorter 

 filaments and longer anthers and larger rudimentary gynoecium. 

 The hexamerous flowers were at first thought to be another point of 

 difference ; but examination of Zenker 1093, on which the genus 

 Avas founded, proves Engler to have been wrong in describing the 

 flowers as pentamerous, for both species have a 6-denticulate calyx, 

 6 petals and 6 stamens.

Gossweiler's 6521, also from Buco Zau, is evidently the same 

 thing with still larger leaves (up to 20 X 10 cm. 



Differs from S. Zenkeri Engl., which it closely resembles exter- 

 nally, in the broader leaves wider at the base, the more conspicuous 

 calvx, the longer filaments and the bent nearly glabrous rudiment of
