Willdenow, which Sir J. E. Smith places under Afzelia, or it may be 
found to belong to one of the neighbouring genera duthonota, Ber- 
linia, or Cynometra. 
86 a. Desmanthus virgatus, Willd. This, which forms part of 
our collection, is not mentioned as occurring elsewhere on the west 
coast of tropical Africa. It is found plentifully throughout the West 
Indies, and has probably been introduced into the Cape de Verd 
islands, 
89 a. Acacia Arabica, Willd., a tomentosa, Benth. A fragment of 
this tree, which produces a red gum of no commercial value, and 
Which, under a variety of forms, is found both in Africa and Asia, 
occurs in our present collection. 
89 4. Dialium anomalum, sp. nov.* This singular plant, though it 
differs essentially from the species of Willdenow and Afzelius, D. Gui- 
neense (D. nitidum, Guillem. et Serr.) yet must necessarily appertain to 
the same group, whose generic character may be easily modified to 
admit it. The D. Guineense varies much in the number of its floral ap- 
pendages, but never to the extent of the present species, as may be - 
seen by the description below. The common type of the flower of D. 
Guineense is that given in the * Flora of Senegambia,’ but from the in- 
spection of several flowers from specimens in the herbarium of Mr. 
Gay, I find that the so-called petal is frequently wanting, and the 
Ovary is then opposed to a void space as it is frequently in our plant,
