OF WEST EQUINOCTIAL AFRICA. 151 
thusia (foliis simplicibus), and also a multitude of species, almost 
all large trees, of the families Hypericacee, Rubiaceae, Bignontacea, 
Verbenacee, Leguminosae, Mimosee, &c. But what particularly 
delighted me was the discovery of Monodora Myristica, already. 
supposed to be native here by R. Brown, which is a native of all 
the primeval forests of these districts, and which represents one 
of the most gigantic and certainly one of the most splendid forest 
trees of the whole of tropical Africa. Later I found at Pungo 
Andongo, a second species, specifically different in the leaves and 
fruit, which I have named Monodora Angolensis. I will send many 
fresh seeds of both to England. 
Terrestrial and parasitical Orchids are pretty tolerably abundant. 
Among the former there is one remarkable species, probably of the 
genus Lissochilus, distinguished by broad leaves nearly 5 feet long ; 
a flower-stem 10 feet to 12 feet high; and particularly by a spike 
of blossoms often 1}-foot long, bearing twenty to twenty-five large 
rose-coloured flowers. This is probably the largest and most 
magnificent of all terrestrial Orchids hitherto discovered. Of this 
species I have roots ready to be sent to London at the first direct . 
opportunity which offers. To show the gigantic dimensions of 
this species, I shall send you the dried flower-stem. Generally 
speaking, the whole vegetation of Golungo Alto has a truly gigantic 
character, so that there is no room left for the growth of smaller 
plants, especially annuals, with the exception of some Graminee 
and Cyperacee. An Umbellifer, whose leaves at the same time 
form one of the most famous remedies of the negroes, occurs in 
the form of a large tree of 1 foot to 15 foot in diameter, used as 
timber ; likewise, among the numerous and in most instances 
woody Composite, there occur two species as strong lofty trees. 
Almost all the Artocarpee which are found here will form quite 
new and very remarkable genera, but at the same time will show 
in the clearest light the transition of this family into the Moree 
on one side, and the Urticee on the other. A genus nearly allied 
to Dorstenia grows as a large woody shrub 4 feet high, in general 
habit like a Fig; but the receptacles are obconic, truncate, and open, 
just as in Kosaria. Also among the Sapindacee and Combretacee, 
and especially among the Leguminose, many highly interesting 
new genera are to be found. 
The most interesting fact in Phytogeography will be that I 
have found here a Begonia, a Hypoxis, an Ottelia, a Gnetacea, 
a Balsaminea, and two Cedrelee—all families of plants which 
have not before been met with in tropical Africa. А still more
