Notes
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-lipped, and the spikes strobilate.
