7. X. acutiflora, A. Rich. Fl. 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. Elowers axillary, 1-1 1- 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-seriate. 

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

8. X.? polycarpa, OUv. 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, 

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

 brous, on stipes of 1-1 1^ 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 lO-oo ; 

 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 shrubs, with penniveined leaves, glabrous or glabrescent in the African species. 

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

 yellow or greenish-white in the African species. 



I follow Mr. Beuthara in including 0. hamata in the same genus with the three other 

 African species, which he associated with it in Oxymitra, although that species and 0. myris- 

 ticifolia appear to me generically different from the rest. They differ in the form of the 

 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 species 

 occur out of the continent, and noue 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 

 hooked \. 0. hamata.
