Floni, of the Malayan Peninsula. 423 



olivaceous and shining on the upper surface, dull and rather paler and 

 minutely rusty-puberulous on the lower ; margins recurved ; 3 to 4 in. 

 long, 1 to 1-25 in. broad; midrib stout, impressed above, raised beneath; 

 main nerves very many, 25 to 30 or more, difficult to distinguish from 

 the similar but rather fainter secondary nerves, these latter recurrent- 

 branched, all meeting an obscure intramarginal nerve, nearly at right 

 angles to the midrib, obscure on both surfaces but slightly raised on 

 the upper ; petiole "25 in. long, rusty-pubescent, bordered by the 

 decurrent margins of the blade. Floivers not known, but fruiting cymes 

 axillary, scarcely longer than the petiole, few-flowered. Fruit of 1 or 

 2 long-pedicelled drupes ; pedicels "3 to 4 in. long ; drupes oblong 

 ellipsoid, acute at both ends, -75 in. long, -35 to 45 in. broad ; pericarp 

 black and wrinkled when dry. Seed conform to the drupe but rounded 

 at the ends, grooved on one side where it is attached to the placenta ; 

 testa thin, separated ; albumen horny, much ruminate in horizontal 

 lamellae ; cotyledons oblong, -2 in. long, -075 in. broad ; radicle stout, 

 cylindric, '225 in. long.

6. Rauwolfia, Linn. 



Trees or shrubs, glabrous or rarely pubescent. Leaves 3- to l-nately 

 whorled or opposite (rarely) ; nerves slender. Floivers in corymbose or 

 umbellate cymes, usually compound, alternate with the terminal leaves 

 or axillary to the upper leaves. Calyx short, 5-lobed, eglandular. 

 Corolla-tube cylindric, sometimes dilated opposite the stamens, con- 

 stricted at the mouth, the throat usually hairy within ; lobes 5, broad, 

 overlapping to the left. Stamens included in the corolla-tube above the 

 middle ; filaments short ; anthers small, acute, rounded at base. Disk 

 cup-shaped or annular. Cari^els 2, distinct or connate ; style filiform ; 

 stigma broad, calyptriform or peltate ; ovules 2, collaterally placed, in 

 each carpel. Fruit of 2 connate or distinct drupes, each with a 

 crustaceous 1-seeded pyrene. Seeds ovate ; testa thin ; albumen thin, 

 fleshy; cotyledons flat; radicle large, superior. — Disteib. About 

 50 species, chiefly tropical American ; about 10 from India and the 

 Malay Peninsula and islands.
