which is more or less pilose-pubescent at first ; lateral leaflets |— | in. long ; 

 common petiole winged between the pairs of leaflets, pubescent beneath. 

 Cymes few-flowered, racemose in the axils of, and shorter than or equalling, 

 the uppermost leaves. Calyx 5 -partite, with ovate pubescent lobes. Petals 

 elliptical, subvalvate, pubeinlous outside. Stamens 10 ; filaments with an 

 adnate, entire, pilose scale. Ovary 5-lobed, with a short central simple style 

 and 5-toothed stigma. Fruit not seen. 



Nile Ijand. Madi, "White Nile, Speke and Grant ! 



Very nearly allied to H. {Lasiolepis) paudjuga, which differs principally in its longer 

 style, more capitate stigma, and less distinctly lobed or merely sulcate ovary. The relative 

 length however of style and stigma appears variable in the Malayan plant, the difference 

 being probably sexual. 



5. QUASSIA, Linn. ; Benth. et Hook. f. Gen. PL i. 3Q8. 



Flowers hermaphrodite. Calyx small, 5-paitite ; lobes imbricate. Petals 

 5, many times longer than the calyx, erect or ascending, broadly iuibricate. 

 Stamens 10 ; filaments filiform or linear, with an adnate pilose scale. Ovary 

 5-lobed; lobes free, inserted upon a fleshy disk ; styles united throughout; 

 stigma obtuse, subcapitate or 5-sulcate. Ovules solitary, pendulous. Drupes 

 5 or fewer. — Glabrous trees, with an intensely bitter taste. Leaves alternate, 

 imparipinnate; lateral leaflets opposite. Eacemes terminal, simple or 

 branched. 



The only other species, the well-known Bitter-wood, is tropical American. It differs from 

 ihe African plant in its much larger flowers, longer filaments, glabrous ovary, the broadly 

 alate rachis of the leaves, etc. 



1. Q. africana, Baillon in Adans. viii. 89. Eight or twelve feet in 

 height, perfectly glabrous. Leaves 5-7-9-foliolate, 1 ft. or more in length ; 

 rachis slightly margined, 3-4 in. to the first pair of leaflets. Leaflets rather 

 coriaceous, oblong-elliptical with a very narrow obtuse acumen, rather oblique 

 at the base and narrowed to the rachis ; terminal leaflets equalling or scarcely 

 larger than the lateral ones, more gradually narrowed above and below, 4-5 

 in. long, 1^-2 in. broad. Inflorescence terminal, racemose, 2^-4 in. long. 

 Flowers about \ in. long, rather crowded and fascicled 2 or 3 together or on 

 very short lateral peduncles ; bracts minute, triangular ; pedicels much 

 shorter than the flower. Calyx-lobes rotundate, ciliolate. Petals linear- 

 oblong, ascending, free. Lobes of the ovary free, pubescent ; disk scarcely 

 as broad as the ovary. Fruit not seen. — Simaba africana, Baill. in Adans.

The description is based on Mr. Mann's specimens, the leaves of which are 7-9-foliolate. 



6. MANNIA, Hook. f. ; Benth. et Hook. f. Gen. PI. i. 309. 



Flowers hermaphrodite. Calyx 5 -partite ; lobes orbicular, imbricate. 

 Petals 5, oblanceolate-oblong, obtuse, rather fleshy, imbricate. Stamens 15 ; 

 filaments narrow-linear, with a short, adnate, pilose, narrow scale near the 

 middle; anthers linear. Disk flattish, fleshy, within the stamens. Ovary of
