In his. Revision (Trans. Linn. Soc. xxx. 519, 520), Bentham - 
observes that A. Catechu, Willd., A, Suma, Kurz, A. hecatophylla, 
Steud. and A, caffra, Willd., “are very difficult to distinguish 
from.each other in dried specimens, and the.synonymy is much 
confused. . . . It might be better, perhaps, to consider 
A. Catechu as a collective name, and to include in it A. Rovumae, 
A. Sundra, A. Suma, A, hecatophylla and A. caffra.” He decided, 
however, to limit the use of the name A. Catechu to one of the 
tropical Asiatic species, excluding from it all the African material 
‘which he placed under A. Suma and A. caffra. 
‘In a MSS. note at Kew under A. campylacantha, Hochst., 
Prof. Craib notes that “the African plant comes very near to 
the Indian Catechu group, and in that group comes nearest to 
. Suma, Ham. (vide Prain, Journ. As. Soc. Beng. lxvi. 508, 
‘for Key to group), but. is distinguished by its curved spines (the 
upper margin of spines in the Indian plant is straight, but in 
the African curved). The Nigerian plant is rather more robust 
‘than the Abyssinian, but intermediates are found in the Nyasa 
region. The Rhodesian plant agrees with some Nyasa specimens 
‘in being rather densely glandular.” 
On the Blue Nile, opposite Singa, the tree yields a good 
timber and is known as “ Kakamut,” in Arabic (Muriel). 
_ In Bornu, ease: Nigeria, it yields the gum known as 
** Kolkol ” (K.P Rae) or “ Kalkara”’; in Yola the tree is 
known as “Cumbanchahon” and viehis a’ ‘gum of good 
‘quality’ (B. E. B. Shaw); according to Mr. G. C. Dudgeon, 
‘the tree is not uncommon on the Rogo road between Kano and 
‘Zaria, where it is known as “ Massasa agi.”
