Cochin-China consists chiefly of an immense plain, flat and monotonous, traversed by the Mekong and extending from Ha-Tien in the west to Baria in the east, and from Bien-Hoa in the north-east to the southern point of the peninsula of Ca-Mau in the south-west.
The last spurs of the mountains of Annam, which come to an end at Cape St Jacques, extend over parts of the provinces of Tay-Ninh, Bien-Hoa and Baria in the north-east and east of the colony, but nowhere exceed 2900 ft.
Cominia), jigiie (jique, Lysiloma sabicu), mahague (Hibiscus tiliaceus), granadillo (Brya ebenus), icaquillo (Licania incania) and agua-baria (Cordia gerascanthes) are perhaps the most beautiful.
Other woods, beautiful and precious, include guayacan (Guaiacum sanctum), baria (varia, Cordia gerascanthoides) - the fragrant, hard-wood Spanish elm - the quiebra-hacha (Copaifera hymenofolia), which three are of wonderful lasting qualities; the jiqui (Malpighia obovata), acana (Achras disecta, Bassia albescens), caigaran (or caguairan, Hymenaea floribunda), and the dagame (Calicophyllum candidissi- mum), which four, like the culla, are all wonderfully resistant to humidity; the caimatillo (Chrysophyllum oliviforme), the yaya (or yayajabico, yayabito: Erythalis fructicosa, Bocagea virgata, Guateria virgata, Asimina Blaini), a magnificent construction wood; the maboa (Cameraria latifolia) and the jocuma (jocum: Sideroxylon mastichodendron, Bumelia saticifolia), all of individual beauties and qualities.
Of Asmara, is the centre for a district (Bogos) fertilized by the upper course of the Anseba; Agordat, on the river Baraka, on the road from Keren to Kassala, is the centre of the Beni-Amer, Algheden and Sabderat tribes; Mogolo, on the lower Mareb, is the rendezvous of the Baria and Baza tribes.
