PHANEROGAMS— PROFESSOR BAYLEY BALFOUR. 55 



The foliage of our plant, especially the shape of the leaflets, with their pellucid 

 veins, easily distinguishes it. With B. Myrrha, Nees (Plant. Medic, ii. 1828, 

 t. 357), a Somali Land plant, there are also resemblances. 



A species sent by Hildebrandt from Somali Land, n. 1383, Schweinfurth 

 suggests may be our plant. I doubt it. Dyer regards it as B. opobalsamum, 

 Kth.

 Appendix and Introductory Chapter.

Another gum-resin producing tree, with pinnate leaves, and quite distinct 

 from all others in the genus by its small leaflets, which are almost glabrous, and 

 its contracted branches, which are larger than is common. 



Our specimens are very poor, and do not afford sufficient data for a very 

 good description. We found the plant on the limestone plateaux west from 

 Kadhab plain. 



Its nearest ally is probably B. pubescens, Stocks (in Bomb. Trans. 1847, ex 

 Hook in Kew Journ. Bot. i. (1849), 264, t. ix. ; A. Benn. in Hook. Flor. Brit. 

 Ind. i. 529) ; a Scindh plant.
