with fan-shaped fronds and an undivided caudex. It therefore more probably 
belongs to Corypha than to Geertner’s Hyphzene, one species of which is the 
Cucifera of Delile, the Doom of Upper Egypt; the second, Hyphaene coriacea, 
is a native of Melinda, and probably of Madagascar, and both are remarkable 
in having the caudex dichotomous, or repeatedly divided. 
As the Palm on the banks of the Congo was seen in fruit only, it is not 
difficult to account for Professor Smith’s referring it rather to Hypheene than 
to Corypha; Geertner having described the embryo of the latter as at the base 
of the fruit, probably, however, from having inverted it, as he appears to have 
done in Eleis. It is at least certain that in Corypha Taliera * of the continent 
of India, which is very nearly allied to C. umbraculifera, the embryo is 
situated at the apex as in Hypheene. 
The journal also notices a species of Raphia, which is probably Raphia 
vinifera of M. de Beauvois,+ the Sagus Palma-pinus of Geertner. 
The collection contains fronds similar to those of Calamus secundiflorus of 
M. de Beauvois,} which was also found at Sierra Leone by Professor Afzelius ; 
and a male spadrx very nearly resembling that of Elate sylvestris of India. 
The Cocoa Nut was not observed in any part of the course of the river. 
Only five species of Palms appear therefore to have been seen on the banks 
of the Congo. On the whole continent of Africa thirteen species, including 
those from Congo, have been found; which belong to genera either confined to 
this continent and its islands, or existing also in India, but none of which have 
yet been observed in America, unless perhaps Elais, if Alfonsia oleifera of 
Humboldt should prove to be a distinct species of that genus. 
CYPERACE. In the collection there are thirty-two species belonging 
to this order, which forms therefore about one eighteenth of the Phanogamous 
plants. ‘This is very different from what has been considered its equinoctial 
proportion, but is intermediate to that of the northern part of New Holland, 
where, from my own materials, it seems to be as 1:14; and of India, in which 
according to Dr. Roxburgh’s Flora it is about 1:25. 
In other intratropical countries the proportion may be still smaller; but I
