elongated 3-bracteate peduncle and persistent calyx, ovoid, longi- 

 tudinally 2-costulate; epicarp coriaceous, 2-valved; putamen cliar- 

 taceous, incompletely 2-localar ; seeds descendent ; cotyledons of 

 exalbuminoiis embryo struiglit flat;' radicle short superior. — A small 

 tree ; coma loose ; branches tuberculate cicatrised ; leaves at summit 

 of twig's, alternate petiolate, digitate-3-7-foliolate ; flowers (small) 

 axillary; male crowded cymose-fesciculate ; cymes contracted in 

 dense bracteate involucrate capitules ; female sub-solitary at external 

 side 3-bracteolate.~ {Angola.^) 



9. Boswellia Koxb.' — Flowers hermaphrodite, 5-merous ; calyx 

 gamophyllous, imbricated, ^-dentate. Petals longer, imbricated,

 annular crenate disk, 2-seriate ; filaments free ; anthers introrse, 

 2-rimose. Germen sessile, 2- or oftener 3-locular ; style short, stig- 

 matiferous capitate at apex, 2-3-lobed ; ovules collateral 2 (of Bur-

 pyrenas 2, 3, afterwards naked, inserted in central angle of wing, 

 finally solute. Seeds solitary in pyrenas compresso-marginate ; co- 

 tyledons of exalbuminous embryo, contortuplicate multifid. Bal- 

 samic trees ; leaves alternate imparipinnate, often collected at summit 

 of twigs, deciduous ; flowers in terminal or axillary recemcs, sparsely
