Forest Flora of Portuguese East Africa. 
with solitary ovule pendulous from a basal funicle. Styles 3, free or connate below; ovary of male flower abortive or absent. Drupe usually dry, with a coriaceous 
or ligneous putamen, 1 -seeded, exalbuminous. Many species, of which nearly half are South African, and of these a good few extend into the^southern forests of 
this Province. These are 3-foliate useless shrubs or shrublets, for which see “Flora Capensis,” I. 506, and “ Forest Flora of Cape Colony," page 192. Among the 
vcrn. names for these I noted the following, viz.: — 4, Hlaba-kunkune ; 6, Gandasendua; 10, Anamaka and Siwawe; 15, Illongoshan, Umhlanyoni and Pembet. 
Of the i-foliate species which constitute the sub-genus Anaphrenium, the following occur : — 
R. longifolia, Sond. A large tree found throughout the Province, as also in Cape Colony and Natal. Leaves alternate, oblong or elliptical, tapering to each end, 
undulate, 10-15 c.m. long, 34 c.m. wide, petioled, glabrous, green above, pale below. Panicles terminal on main and side branches, large or small, canescent. 
Drupe oblique, 1-1*5 c - m - long, almost black. This and the 2 following species are not separated in native opinion, and the following names are used for the 3, 
viz. 4, isi-nungu-mafe ; 5, 6, Sassa, Satsa or Intsatsa ; 10, Na-kadi, Mkakambi, or Mikatanguo ; 12, isi-fuce or isi-fika ; 13, Umkomiso; 15, Siete. 
R. insignis, Delile. A smaller tree than the last, often only 3-5 metres high ; leaves 9-10 c.m. long, 2 c.m. wide, glabrous above, silvery below, usually ternate. Panicles 
pubescent. Abundant Maputa to M’Chopes, present but less frequent on the Zambesi and northward. Too near R. mucronifolia, Sond. 
R. Salicina, Sond. Small tree 3-5 metres high ; leaves oblong, mucronate, hairy on the upper surface, pubescent and somewhat silvery below, alternate, sub-opposite and 
ternate. On the top of the Lebombos near Estatuene. 
In the forests of Magenja da Costa coppice shoots were found where the roads had been cut, which had elliptical leaves 12-15 c.m. long, 4-6 c.m. wide, green 
and softly pubescent on both surfaces, which surroundings indicated to be coppices of Rhus longifolia. If so, the 3 species here mentioned should be regarded as 
forms rather than species. 
83. SORINDEIA. Flowers small, polygamous or dioecious, in terminal or axillary panicles. Leaves pinnate. “ Petals valvate or sub-valvate. Ovule suspended near middle 
of cell.” As the only species found in the Province is included in the genus with doubt by Prof. Oliver in “Flora of Tropical Africa," and differs generically from 
the other species, further characters are here omitted and given only for that species, of which my material is insufficient to constitute the new genus which will be 
required when complete material is obtainable. 
S. (?) trimera, Oliv. Vent, name — 10, Msamba. A very large glabrous tree, growing near streams in Magenja da Costa and Nhamacurra. Leaves alternate, 22-30 c.m. 
long, imparipinnate ; leaflets about 4 opposite pairs and terminal one; 5-10 c.m. long, 5 c.m. wide, elliptical, bluntly pointed, entire, firm, glabrous, with stout 
petiole 5-10 m.m. long and pronounced midrib. Panicle terminal 8-20 c.m. long, many-flowered, seen by me in fruit only. Fruit 3 c.m. long, 2 c.m. diameter, ovate, 
green, seated in the persistent 3-lobed calyx, within which and under the fruit 3 oblong petals and 6 filaments often remain under a membranous disc-ring. The 
filaments do not show whether all are stamens or 3 staminodia. Fruit with hard bony putamen, 3-celled, usually only 1 cell fertile, 1 -seeded, the seed nearly flat, 
pendulous from near the top of the axile placenta, exalbuminous. Juice of the fruit resinous, exceedingly viscid, and smells strongly of turpentine. Juice of stem 
watery or somewhat milky, flowing freely and drying to a gum used for caulking boats. Formerly recorded only from West Africa. This will probably prove a 
valuable timber tree, and is often 100 to 150 c.m. diameter. The 3-celled fruit, 3-merous flowers and opposite leaflets all indicate that this tree is out of place in 
this genus.

84. MANGIFERA. Mowers polygamous or dicecious. Calyx 5-lobed ; petals 5, imbricate in aestivation; stamens by abortion usually 1 ; ovary free, sessile, 1 -celled ; drupe 
1 -seeded, more or less edible, with a fibrous fleshy mesocarp and a large bony putamen. Leaves simple, entire, alternate. 
M. indica, Linn. Fern, names 1, Mango; 2, Manguiera. A large glabrous tree, having many more or less permanent varieties differing among themselves in foliage 
and fruit, leaves oblong-lanceolate or wider, 12-24 c.m. long, 3-6 c.m. wide, acute, petioled. Panicle terminal, many-flowered, 10-30 c.m. long. Fruit obliquely 
oblong, ovoid, or curved 8-16 c.m. long, 4-8 c.m. wide, somewhat compressed, and variable in regard to colour, flavour, and amount of fibre, but including varieties 
whiih are first-rate dessert fruits. Male flower— calyx-segments 5 ; petals 5 ; stamen 1 among incurved glands. Female flower — no stamens; ovary 5-lobed, with 
central subulate style. Probably originally introduced from Asia, but now widely dispersed throughout the tropical forests, and usually the largest trees in these 
forests, often up to i£ metres diameter, and used to make the largest dug-out boats (Mandea).
