Var. tenuifolia. Leaves thinly coriaceous or snbmembrauous, broadly elliptical or ob- 

 ovate-elliptical, obtuse or shortly and broadly apiculate.— I. tenuifolia, Hook. f. 1. c,

Barter calls this the " Wild Mango " of the " Sierra Leone people." I have not seen 

 specimens from Sierra Leone. In the var. tenuifolia the style in uninjured flowers is slender 

 and elongate as in the type. 



2. I. Smithii, Hook. f. I. c. A perfectly glabrous tree of 40 ft. {Barter), 

 ultimate branchlets usually slightly furrowed when dry. Leaves very coria- 

 ceous, ovate-elliptical, acute or broadly pointed, broadly rounded at the base 

 and usually more or less narrowly cordate at the insertion of the petiole, Sf-4 

 in. long, lf-21 in. broad ; petiole 1 in. Flowers numerous, pale yellow, 

 fragrant, " in spreading axillary and terminal subpaniculate, narrow racemes, 

 equalling or exceeding the leaves." Pedicels singly inserted along the raehis, 

 patent, equalling the flowers. Style about equal to the ovary at flowering. 

 Fruit oblong (in our dried specimens), nearly 11 in. long, with a thick woody 

 pericarp. Seed, according to M. Baillon (Adans. vii. 381), albuminous.

 Mr. Barter says the fruit is much sought after by monkeys.
