OF WEST EQUINOCTIAL AFRICA. 155 
regions appears at one time pink, at another time sky-blue. A 
large Kniphofia, of 6 to 8 feet, is the queen of the lilies, whilst 
several new genera allied to Anthericum and Scilla, together with 
Chlorophytum, Sanseviera, and pretty Asparaginee, form as it were 
the underwood of the lilies. One Tacca and two Hamanthi, 
together with Crinum and a small-flowered Narcissea, adorn the 
skirts of the forests, besides a countless number of little Rubiaceae, 
with sky-blue or rose-coloured flowers. Species of Hibiscus ap- 
pear everywhere. The Violarie are represented by three: Ceran- 
there in the form of small trees (one with the habit of Zler 
aquifolium !). : A Myricacea, with an extremely delicious powerful 
smell, forms quite а new genus, which is only related to Comp- 
tonia in the formation of the anthers; but it has, like no other 
Myricacea, opposite leaves. I have described it as Myrothamnus 
Jlabellifolius. Pistia and Ceratophyllum, with an Azolla and a 
Marsileacea, abound in the fresh water with Polygonacee and 
Scirpoide@, accompanied almost everywhere by two or three 
species of Nymphaea (Nymphea Lotus, P. de B.), whilst a Ruppia 
(similar to R. maritima) and several Chare fill the stagnant water. 
Among the climbers are two species of Hugonia, a 5-gonous 
Mimosa, and several species of Strophanthus. Among others 
Asclepiadee are also numerous, and mostly climbers. Also an 
Oleacea occurs as a large tree; and tree-like Huphorbiacee (Bri- 
delia, &c.) are found everywhere. The Daphnoidee are repre- 
sented by a very pretty scarlet Gnidia, the Proteacee by two 
thickheaded Protee. Labiate and Verbenacee are in great abun- 
dance everywhere; the latter and several Acanthacee mostly 
assume the forms of trees or shrubs. Loranthacee glitter fre- 
quently from out the dark-leaved tops of the Combretacee and 
Anonaceg; but they occur also on Mimosee, and (in spite of 
De Candolle's assertion) very frequently on fig trees, even on the 
cultivated Ficus Carica. Celastrine, Hippocrateacee, and Chail- 
letiee are not numerous. Of Myrtacee@ were observed ten, of 
Melastomee only thirteen species, of Connaracee eight, of Ly- 
thracee ten or twelve species, of Ranunculacee I have five species 
of Clematis; of Rosacee І have found only one Rubus (apetalus). 
A Cochlospermum, as a tolerably large tree, is to be met with 
everywhere ; besides, I have to enumerate five Piperacee and two 
Dorstenieg, among which occurs a Kosaria. These all appear to 
be new species. The Scrophulariacee, of which there are about 
thirty species, principally adorn the meadows where they grow, 
with four species of Eriospermum (Liliacee), with several species
