B. hispinosa, Vahl, is an Arabian plant with pale-purple flowers. B. induta is 

 very near B. Priotiifis except as to the many hairs permanent on the leaves.

Interpetiolar spines 2 or 3 together, some short, some 1 in. long. The present 

 plant is distributed by Schweinfurth and Barbey (specimens collected in Arabia 

 Felix) as the true B. trispinosa, Vahl, and doubtless rightly, as Forskal in his 

 original description says the flower was fulvous-yellow, 2-lippedj and the spikes 

 strobilate.
