526 FLORA NIGRITIANA. 
satisfactory affinity with it has yet been indicated, and it remains 
an isolated species which cannot be associated with any known 
Order. The calling it an Order of itself, does not appear to me 
to throw any additional light on the matter. 
Dicotyieponegs dubie. 
There remain six or seven fragmentary specimens, which we ; 
have successively rejected from all known forms in each 
natural Order with which we had at first compared them, and 
far too incomplete for any specific mention. They show, how- 
ever, as well as the large number of species hereinbefore men- 
tioned as imperfectly known, how much there is still for bota- 
nists to do who may in future risk their lives in these regions, 
so pestiferous for the human race, but so favourable for vegetable 
development. 
XCVI. Patz. 
Of this Order, the only fragment in the collection is a leaf of 
the Elais Guineensis; and not more than six species appear to 
have been observed in West Tropical Africa, viz.: 1. Calamus 
secundiflorus, Beauv., extending from Senegal to Benin. 2. Bo- 
rassus ZEthiopum, Mart., Senegal to Benin. 3. Hyphene Gui- 
neensis, Schum. et Thonn., referred by Kunth to the Egyptian 
Doum Palm, (Hyphene Thebaica, Mart.): Brown suggests, 
however, that the Palm called by Prof. C. Smith Hyphene, 15 
probably not of that genus, as having a single stem. Thonning, 
in his deseription, does not mention the branching stem, and 
his detailed account of the male flowers does not agree with 
Martius’ generic character of Hyphene. 4. Raphia vinifera, 
Beauv., one of the Wine-palms, from Sierra Leone to Benin. 
5. Phoenix spinosa, Schum. et Thonn., another of the Wine- 
palms, according to Thonning ; Guinea, and said also to be 
found in Senegal and at the Cape of Good Hope. 6. Flais 
Guineensis, Linn., or Oil-palm, also a Wine-palm, and, aceord- 
ne to Thonning, common, both wild and cultivated. Horne- 
mann is said by Nees v. Esenbeck, to observe that Thonning’s
