or serrate often coriaceous pellucid-punctuate ; racHs simple or

5 ? Crepidospermum. Hook, f.^ — Flowers polygamous-diajcions 

 (nearly of Bursera); calyx small, 5-dentate. Petals 5, longer, 

 valvate, incurved at apes. Stamens 5, alternipetalous, inserted 

 below thick pulvinate disk ; filaments free ; anthers oblong in- 

 trorse. Germen rudimentary thin subulate. Female flower? Fruit 

 drupaceous,'^ compressed-subquadrate apiculate ; pyrenas 1-3, char- 

 taceous and crustaceous ; seeds 1, 2, desceudent ; others usually ab- 

 ortive very small ; cotyledons of exalbumiuous horseshoe-shaped em- 

 bryo oblong uncinate-incurved ; radicle short superior. — A balsamic 

 shrub ; branches elongate-sarmentaceous ; twigs, leaves and inflores- 

 cence pubescent ; leaves alternate imparipinnate ; folioles petiolate ser- 

 rate acuminate ; axillary inflorescence of Bursera. {East PeniJ) 



6. Balsamea Gled.^ — Flowers polygamous (nearly of Bursera) 

 rarely 5-6merous, very often 4-merous ; calyx cupular or urceolar 

 dentate, valvate, persistent. Petals elongate erect or patent at apex, 

 valvate or induplicate. Stamens 2 -senate, twice as numerous as 

 the stamens sub-hypogynously or much oftener slightly perigyn- 

 ously inserted with them on margin of usually rather concave recep- 

 tacle ; filaments free, moi'e or less dilated at base ; the oppositi- 

 petalous shorter ; anthers introrse, 2-riniose (effete in female flower). 

 Gormen free (rudimentary in male flower), inserted on summit of 

 depressed disk; germen 3- or oftener 2-locular ; style short, stigma- 

 tiferous obtusely 3-4-lobed at apex ; ovules in cell 2, collaterally 

 descendent ; micropyle extrorse superior. Drupe ; exocarp 2-6-valved ; 

 pyrenas 1-4, 1-spcrmous; cotyledons of exalbuminous embryo
