 glabrous, about 3 in. long, l£ in. broad; petiole 1 line. Pedicels \-\ in., 

 very slender, like the petioles puberulous. Outer petals obtuse, plane, 5-7 

 lines long in our specimen ; inner petals 2-3 lines, more or less connivent. 

 Anthers linear, 2-3 times as long as broad, with a dilated, rhomhoidal, trun-

 Ovules 3 or 2, superposed. Fruit not seen.

5. O. patens, Benth. I.e. t. 51. A glabrous tree, attaining a height of 

 70 ft. Leaves rather coriaceous, at length oval-oblong or elliptical, some- 

 times narrow and elongate, acuminate, the base acute or cuneate ; shining, 

 with looped lateral nerves above ; 5-7 in. long, 1^-lf in. broad ; petiole 2-6 

 lines. Flowers greenish -yellow, on slender naked pedicels, f-1 in. long. 

 Outer petals obovate-oblong or oval, rather obtuse, 4-6 lines long, spreading; 

 inner petals broadly ovate or triangular, connivent. Anthers very short, 

 truncate; connective much dilated over the cells. Carpels about 10; ovules 

 2, sometimes with a septum more or less developed between them. Unripe 

 fruit-carpels very shortly stipitate, globose, 1 -celled, or 2-s'eeded with a dis- 

 sepiment between the seeds.

Dr. Welwitsch collected in the island of St. Thomas an Anonacea in fruit, which is pro- 

 bahly allied to this species. The leaves are broader and the stipes of the globose carpel*

 Flowers hermaphrodite. Sepals 3, nearly or quite free in the African species, 

 valvate or very slightly imbricate at the base. Petals 6, in 2 series, pla" e ' 

 spreading or the base more or less connivent around the genitalia, nearly 

 equal or the inner shorter or rarely wanting. Stamens indefinite, oblong- 

 quadrate or -cuneate ; connective thickened and globose or truncate and dilate" 

 above the anther-cells. Torus plane or convex. Carpels indefinite (3 lB

 the inner face (capitate in U. ? lepidota) ; ovules 2-oo, 1-seriate or sub-z- 

 seriate. Fruit-carpels usually stipitate, constricted between the seeds or con- 

 tinuous or ovoid.— Trees or shrubs, erect or scandent. Flowers solitary <*
