7. X. acutiflora, A. Rich. II. Cub. 55 {in note). A much-branched shrub 

 or small tree, with slender, minutely pubescent or pilose extremities. Leaves 

 oval- or lanceolate-oblong, usually narrowed to a rather obtuse or scarcely 

 acute point, more or less coriaceous, glabrous and rather shining above, mi- 

 nutely silky-pilose beneath or glabrescent, midrib pubescent or pilose ; 2-3 

 in. long, 7-12 lines broad; petiole 1-2 lines. Flowers axillary, 1-li in. 

 long ; pedicels with 1 or 2 small bracts ; buds narrow, acuminate. Sepals 

 ovate, acute. Petals linear-subulate, at length more or less spreading ; styles 

 connivent in a subulate cone. Ovules 8-10, 2-seriate or sub-2-senate. 

 Fruit-carpels oblong, scarcely torulose. — Unona acutiflora, Dun. Anon. 116.

8. X. ? polycarpa, Oliv. Leaves ovate or elliptical-oblong, subacumi- 

 nate, coriaceous, shining above ; pedicels short, axillary, solitary or in pairs. 

 Sepals lanceolate, 4-5 lines long. Petals about 1 in. long, thick, triquetrous, 

 tomentose externally. Fruit-carpels 30 or more, oblong, f in. long, gla- 

 brous, on stipes of 1-1 i in. — Anona? polycarpa, DC. Syst. Veg. i. 499.

11. OXYMITRA, Blume ; Benth. et Hook. f. Gen. PI. i. 26. 



Flowers hermaphrodite. Sepals 3, valvate in aestivation, free or connate 

 at the base. Petals 6, valvate in 2 series in sestivation ; the outer exceeding 

 the inner, often very much longer, tapering, erect or spreading ; inner petals 

 ovate oblong or ovate-lanceolate, connivent around the genitalia. Stamens 

 indefinite, linear, oblong or quadrate ; the connective usually produced be- 

 yond the cells of the sessile or subsessile anther, dilated and truncate (ex- 

 cepting in species 1 and 2). Torus more or less conical. Carpels 10-*" 

 style linear, oblong or obovoid, with 1 basal ovule or 1 to 3 superposed. 

 Fruit-carpels (known only in one African species) stipitate, 1- or 2-seeded. 



Trees or shmbs, with penniveined leaves, glabrous or glabrescent in the African specif 

 Flowers tolerably large, pedicellate, extra-axillary or axillary, solitary or fascicled, usually 

 yellow or greenish-white in the African species. 



I follow Mr. Beutham in including 0. hamaia in the same genus with the three other 

 African species, which he associated with it in Oxymitra, although that species and 0. my T # 

 ticifolw appear to me generically different from the rest. They differ in the form of «* 

 inner petals, their anthers without a dilated connective, and in their solitary erect ovules. 



The genus is confined to the tropics of the Old World. None of the African specK* 

 occur out of the continent, and none have been met with on its eastern side. 

 (§ Stenanthera.) Anthers linear, at least 5 times as long as broad ; 

 connective not dilated and truncate. Ovules solitary. 

 Leaves oblong-elliptical. Sepals minute, triangular, acute, about 

 1 line long. Outer petals elongate, linear-lanceolate, often 

 booked \ q. hamata.
