179. LANDOLPHIA. Widely rambling shrubs, with opposite exstipulate simple entire leaves, terminal small corymbose or paniculate inflorescence, syncarpous i-celled 
ovary, pear-shaped, many-seeded, i-celled fruits, and tendrils which represent more or less modified inflorescence. Style short, not or hardly exserted from the calyx ; 
calyx short, without glands inside. A considerable group, mostly belonging to Tropical Africa and its islands, and yielding much of the rubber exported from East 
and West Tropical Africa. In this Province L. Kirkii is the only Landolphia considered worth tapping under present conditions ; other species occur but are not 
tapped. Concerning rubber see chapter V. L. Kirkii is well known and distinct ; the other species, with the exception of L. florida, were not in condition for 
determination at the time of my visit. 
L. Kirkii, Dyer. Vent, names — 4, i-bungu ; 6, Mungu ; 10, Impela. The rubber is called Dande. A slender and comparatively small-leaved creeper, the old stems 
however sometimes 10-15 c.m. diameter; smaller, more wiry and more sub-erect on sandy coast-lands than further inland. Leaves lanceolate or oblong, 3-8 c.m. 
long, 1-2-5 c.m. wide, shining dark-green above, shortly petiolate. Side veins close, numerous. Inflorescence rather lax in terminal corymbs on side branches. 
Flowers small, corolla-tube 4-7 m.m. long ; ovary glabrous. Fruit globose or somewhat pear-shaped, 5-6 c.m. diameter, with a hard rind, yellow when ripe, dotted 
red or brown. Seed any shape by compression, 1-5 c.m. diameter. Fruit sweetly acidulous, edible, but rather stringy. Abundant in every part of the Province 
north of the Limpopo, present but less plentiful south of the Limpopo extending to the Umhlatuse in Natal. Enjoys best light sandy soil and much exposure, but 
rubber collecting is mostly done in fairly dense forest where the Landolphia is hanging on large trees.

L. florida, Benth. Vern. names — 4, Tamunga ; 10, Mtyili or Moembe, when near water; Mogo, when on dry ground ; or some of these names may refer to other 
species, not L. Kirkii. A strong climber, having the flowers in sessile dense clusters on thick branches of the terminal panicle ; these branches are usually curved 
backward, and with the occasionally twining habit of the main panicle-rachis aid the plant in its scandent habit. Leaves 3-7 c.m. long, 15-4 c.m. wide, elliptical, on 
1 c.m. petioles. Flowers white, scented, beautiful, resembling some Jasminum. Calyx 4 m.m. long, corolla-tube 2-5 c.m. long, 2 m.m. wide, swollen just above the 
calyx ; the lobes 2-5 c.m. long, acute, lanceolate, twisted, 6-7 m.m. wide. Fruit pear-shaped, 5-7 c.m. diameter, yellow, with a thick rind and many seeds. Frequent 
at Rueben Point, Polana, and round Lourenzo Marques. Present also, though less plentiful, throughout the Province.

L. Buchananii, Stapf. This, or a variety of it or allied species, is the Kew identification of specimens sent from Manica and Sofala by Mr. VV. H. Johnston, Director of 
Agriculture to the Mozambique Company, and the species is also recorded from Nyasa-land and Shire Highlands. It is described as a glabrous climber with leaves 
oblong or sub-obovate-oblong, obscurely and obtusely acuminate or obtuse, rounded at the base, 2-4 inches long, g - 1 i inches broad. Corymbs small, few-flowered, 
dense, glabrous, very shortly peduncled or sub-sessile, much shorter than the leaves. Calyx slightly over 1 line long, glabrous. Corolla 2^-3 A lines long, lobes 
oblong, obtuse 42-5! lines long. Ovary glabrous. Fruit globose, i£-if inch diameter. Said to yield india-rubber. 
L. Petersiana, Dyer. Scandent, hanging by sensative inflorescences; young parts pubescent ; leaves elliptic to elliptic-oblong, sub-acute or obtuse at both ends, 6-10 
c.m. long, 3-5 c.m. broad, at first pubescent. Panicle peduncled, bearing clusters of many sessile flowers at the ends of short spreading or recurved rusty-pubes- 
cent branches. Calyx about 1 line long. Corolla white, scented, 8-13 lines long in bud; tube 3 to 4J lines long, lobes 6-8 lines long, curled-ciliate. Fruit globose, 
up to 2J inches in diameter, finely velvety. Zambesia. 
L. Monteiroi (Dyer M.S.), Stapf. A rambling' shrub from Delagoa Bay, described in “Flora Capensis” as having oblong to lanceolate-oblong leaves 46 c.m. 
long, 2-2 5 c.m. wide, shortly petioled ; panicle peduncled, bearing 2-3 dense clusters of sub-sessile flowers at the ends of spreading or recurved branches ; corolla 
white, sweet-scented, up to 4 c.m. long in bud ; tube 2 c.m. long, slightly inflated just above the calyx. Fruit yellow, about the size of a small orange. I ossibly 
this is the same as what is described above as L. florida. 
L. Klainer, Pierre. Is also claimed in the “ Annuario de Mozambique,” 1908, to be one of the rubber-producing species in Mozambique district and to be used as root 
rubber. I cannot say if this identification is correct. L. Klainei as a west coast species belongs to the same group as L. Kirkii, with small flowers ; it has however 
oblong leaves 5 6 inches long, by r£-2 inches wide, and very large globose fruits 6-10 inches in diameter. 
180. CARISSA. Rigid shrubs with opposite simple leaves, terminal or axillary inflorescence, and dichotomously forked branches with once or twice dichotomously forked 
spines in the axils of the branches or where a fork would have been but for the abortion of one part. Flowers scented, white. Calyx small, tubular, 5-parted .
