They are all shrubs of tropical eastern Africa, continental and insular, with flowers in axillary cymes or glomerules often accompanied with pairs of connate bracts forming a sort of calicule. Beside Gremaspora are ranged Aulacocalyx and Belonophora, shrubs of tropical western Africa, which have axillary cymes, and a two-celled ovary with ovules of Ganthium. The Oremaspora microcarpa. former has pointed sepals and ex- serted stamens, whilst in the latter the calycinal divisions are shorter, obtuse, and the stamens shorter. With us these form only two sec- tions of the same genus. Their fruit is unknown. Galiniera, an Abyssinian shrub, which is in the same case and whose inflorescences are also axillary cymes, has penta- merous flowers, with a contorted corolla and two ovarian cells, sur- mounted by a style which may divide into two branches. Each of its cells may contain, it is said, two descending ovules; but most frequently there is in reality only one as in the preceding genera. The style has longitudinal prominences in the form of narrow wings, more marked in the plant of Zanzibar called, for that reason, Ehabdostigma; and Octotropis, of Travancore, may be considered as a Rhabdostigma with tetramerous flowers, eight stylary ridges and two incomplete ovarian cells. With the same gynseCium and a general floral organization quite analogous. Alberta, trees of Madagascar and southern Africa, have sepals of which two, three or four are accrescent above the fruit in membranous spathulate and veined wings. The style is long fusiform, and the inflorescences are terminal. The same is the case with Nematostylis, a shrub of Madagascar, of which only one of the five sepals becomes foliaceous, the corolla is contorted and the long exserted style divides above into irwo lobes; so that this plant connects the preceding types with those of Ixora
