FLORA OF P0RTUGUP:SE EAST AFRICA. 299 



The Baobab and Borassiis both appear in the northern por- 

 tion and Coffee occurs wild. A species of Miniusops yields* 

 Caoutchouc and Laudolphia species yield rubber. 



\^ Extra-Tropical ]\Iouxtain Range. 



This includes the Lebombo Range along- the Natal. Swazi 

 and Transvaal borders — a broken, rocky, rising country, often 

 almost destitute of soil, more or less gras^-clad, but contain- 

 ing occasional kloofs in which trees are abundant and of many 

 kinds, the Cape and Xatal forest species intermingling with 

 species from fiu^ther north, further inland and further coast- 

 ward. This is, consequently, a comparatively rich flora, alike 

 in ligneous, herbaceous and bulbous plants, and includes many 

 tnidescribed species. Combrctum is the prevailing genus, 

 Acacia species occur, Ficns is well represented, Podocarpus 

 is sparingly present, Nuxia oppositifolia forms a large tree, 

 Pcltophorum afyicaiiuin is frequent, Dombcya nntltiflora is a 

 frequent overlap from the high-veld, Adiiia. Artocarpus and 

 Afjjclia overlap from the tropics, while one gregarious tree 

 {WciJicaf subpcltata, Sim) occurs here in abundance and has 

 not been seen elsewhere except specimens from Mozambique. 

 The new genus Diacarpa, having samaroid fruits and pinnate 

 leaves and apparentlv allied to Ptccro.v\lon belongs liere. 



Vl. Tropical Forest Region. 



The whole of the tropical coast belt for loo miles inland or 

 thereby, may be described as one forest, except where too wet 

 for trees to grow. It is a comparatively level tract, alluvial 

 in the low lands, somewhat sandy in the higher, sparsely in- 

 habited, formerly a slave-raiding area, abundantly supplied 

 with tidal rivers, and with considerable lagoons near the coast. 

 The forest is of the evergreen broad-leaved type, but the term 

 broad-leaved must here be understood as including" Legum- 

 inos£e, which order predominates, with pinnate or bipinnate 

 leaves. The Leguminous trees, which include very few 

 Acacias, are of medium size (say, lo to i8 inches stem- 

 diameter) and stand sufficiently far apart to allow a light grass- 

 veld underneath; shrub undergrowth is absent, and dead 

 stumps of former generations are remarkable by their absence, 

 probably through the action of white ants. 



Ptcrocarpus crinaccus, Lonchocarpiis niossanibicciisis, 

 Szi'artcia madagascaricnsis, Bauhinia raticiilata, Afcclia quan- 

 ccusis, Brachystcgia (several species), Tauiarindns indica, 

 Parkia filicoidca, Tctraplcura obtnsaiigiila, and several species 

 of Albiacia are some of the Leguminous trees. 



Much larger and more soft-wooded trees occur of such kinds 

 as Ficus species. Commiphora species, Combrctum species, 

 Cordyla africaiia, Soriiidcia trimcra, Rhus longifolia, Khaya 

 scucgaloisis, Milicia africana, Barrcftia umbrosa, Bcrsama 

 mossambiccnsis, Blighia sapida. Irvingia mossambicctisis, and 

 species of Cola and Stcrculia. 



There are several possibly exotic trees which are now widely 

 scattered throughout these forests, including the Mango, the
