 tudinally 2-costulate; epiearp coriaceous, 2-Talved; putamen char- 

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

 exalbuminous embryo straight flat;^ radicle short superior.— A small 

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

 of twigs, alternate petiolate, digitate-3-7-foliolate; flowers (small) 

 axillary; male crowded cymose-fasciculate ; cymes contracted in 

 dense bracteate involucrato cai^itules ; female sub-solitary at external 

 side 3-bracteolate." {Angola.^) 



9. Boswellia Roxb.* — Flowers hermaphrodite, 5-merous ; calyx 

 gamophyllous, imbricated, 5-dentate. Petals longer, imbricated, 

 finally very patent. Stamens 10, subhypogynously inserted below 

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

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

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

 sera). Drupe 2- or oftener 3-agonal; angles obtuse shortly promi- 

 nent of thick wing-shaped {Triomma ;^) exocarp finally 2-3-valved ; 

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

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

 tyledons of exalbuminous embryo, contortuiîlicate multifid. Bal- 

 samic trees ; leaves alternate imparipinnate, often collected at summit 

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

 or richly composite-ramified. (South West. Asia, 3Ialacca, Trop.
