In many respects S. prunifoJiinn, Klotzscli, resembles S- Aucupariuvf, 

 Jacq., whicli has very long androgynous flower-spikes. The venation 

 of the leaves is less conspicuous than one might suppose from the 

 figure. Ule compares this species with his >S. Tabinu (t. 2898), and 

 S. cglandulosnm (t. 2899).— W. BoTTiyc Hemsley,
