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} in. 
broad; petiole 1 in. more or Jess. 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, 1-1} lines long. Petals about 
twice as long as calyx, linear-spathulate, apex fimbriate-laciniate. Sta- 
mens 10, inserted upon a short sheath-like disk within the petals ; 
cae elliptic-oblong. Ovary hairy, 2-celled; stigma capitate, sub- 
entire. 
Upper Guinea. Nun river, Barter! Gaboon, Mann! 
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, estate obtuse or obtusely apiculate, but apex eroded in our 
specimens, base rounded, undulate-crenate, coriaceous, reticulation not 
prominent, 23-8 in. long, 14-2 in. broad; petiole 4-}in. Flowers 
numerous in rather close glomerules on the nodes of previous year, 
pedicels 1-1} 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 D. 
Barteri; anthers oblong. Ovary glabrous, 2-(3)-celled, the cells appa- 
rently confluent at the apex. 
Upper Guinea. St. Thomas Island, summit of the Peak, Mann! 
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, l-celled, 1-seeded. Embryo exalbuminous, axile ; cotyledons 0 
or minute” (Gardner and Thwaites). Pericarp in some species described
