pendulous. Fruit not observed. — Trees or shrubs ; glabrous. Leaves 

 opposite, petiolate, elliptical, undulate-crenate or entire, coriaceous. 

 Stipules interpetiolar, caducous. Flowers small, numerous, in dense 

 axillary fascicles or glomerules or from the nodes of previous years. 

 A small genus, restricted to Africa and the Mascarene group.

1. D. Barteri, Hook. f. mss. in Herb. Kew. Shrub or small tree; 

 wholly glabrous. Branches terete with thickened floriferous nodes. 

 Leaves coriaceous, broadly elliptical, rounded above or shortly broadly 

 and obtusely apiculate, rounded often broadly at base, entire, reticula- 

 tion more or less obvious above and below ; 4—7 in. long-, 2-3 J in. 

 broad ; petiole \ in. more or less. Flowers numerous, small, in dense 

 subglobose fascicles on the thickened nodes chiefly below the leaves of 

 the present year, subsessile or pedicels about 1-2 lines. Calyx cam- 

 panulate, shortly 5-deltoid-dentate, 1-1J lines long. Petals about 

 twice as long* as calyx, linear-spathulate, apex flmbriate-laciniate. Sta- 

 mens 10, inserted upon a short sheath-like disk within the petals ; 

 anthers elliptic-oblong-. Ovary hairy, 2-celled ; stigma capitate, sub- 

 entire.

2. D. Mannii, Hook: f. mss. in Herb. Kew. Tree of 25 ft., wholly 

 glabrous. Branches terete, the nodes hardly thickened, young extre- 

 mities slightly compressed., Leaves oblong or ovate- elliptical or ellip- 

 tical, probably obtuse or obtusely apiculate, but apex eroded in our 

 specimens, base rounded, undulate-crenate, coriaceous, reticulation not 

 prominent, 2±-3J in. long, 1^-2 in. broad • petiole \-\ in. Flowers 

 numerous in rather close glomerules on the nodes of previous year, 

 pedicels 1-lj lines, articulate. Calyx campanulate-urceolate with 4 

 short triangular teeth. Petals about \ as long again as calyx, linear, 

 slightly dilated and fimbriate at apex. Stamens 8, inserted as in B. 

 BarteHy anthers oblong. Ovary glabrous, 2-(3)-celled, the cells appa- 

 rently confluent at the apex.

6. ANISOPHYLLEA, R. Br. ; Benth. et Hook. f. Gen. Plant, i. 683. 



Flowers small, hermaphrodite or unisexual by abortion. Calyx-tube 

 adnate to ovary, ovoid, limb 4-partite with erect valvate lobes. Petals 

 as many as .calyx-lobes, equalling or scarcely exceeding them, apex 

 lobed or laciniate (or entire). Stamens 8, inserted with the petals; 

 filaments subulate or narrow-linear ; anthers small, ellipsoidal, dorsi- 

 fixed. Ovary inferior, 4-celled; styles 4, short, subulate, dilated at 

 base into epigynous disk; ovules solitary, pendulous. Fruit " indehis- 

 cent, 1 -celled, 1 -seeded. Embryo exalbuminous, axile ; cotyledons 

 or minute" (Gardner and Thwaites). Pericarp in some species described
