N.B.— The flower? -2 all these Acacias turn yellow on drying ; hence 

 they are often described as yellow in descriptions drawn from herbarium 

 specimens.

The following description is taken from Indian Trees ;— 



*' A large or middle-sized tree ; bark white ; branches stiff, fiexuoae ; 

 branchlets and petioles downy, with soft pubescence. Prickles in pairs, 

 infra-stipular, conical, downy while young, brown shining afterwards. 

 Petiole 4-10" long (includes rachis 'f), unarmed, with a large cup-shaped 

 gland above the base. Pinnce 10-20 p*s., lflts. 20-50 prs., linear, approxi- 

 mate, imbricate, generally oiliate. Fl. white or pale yellow ; spikes lax. 

 Petals not much longer than the calyx. Pod. 3-5" by £", pubescent when 

 young." 



Chota Nagpur, Prain. I have not met with it there, but see remarks 

 under A. Catechu. FL r. s. Boxb. 



7. A. Catechu, Willd. Khair, H., S. 



A small or mod. -sized tree with dark coloured bark and 

 slender branches armed with geminate hooked prickles. 

 Pinn© 4-2 ± prs. Lflts. (30-50 prs. or only) 25-30 prs. (rarely 

 more in Ch. Nag.). Petiole with rachis usually 3-4". Spikes 

 axillary on the young shoots 2-3£" dense, nearly white. 

 Petals l±-2-time$ as long as the calyx densely hairy and 

 greenish with membranous margins like the calyx. Ovary 

 glabrous, stalked. 



Manbhum ; Hazaribagh (esp. on sandstone), often with sal ; Palamau 

 common, whereat is found mixed with the sal, both on clay and sandstone

 flowers appear. 



Twigs pubescont. Bachis densely hairy, 2-6"''' rarely 8", pinnae £-l£'' a 

 gland below the pinna and one between the uppermost 1-6 pinnae. Lflts., 

 jo-j" imbrioate, hairy. Peduncles %", sometimes paired. 8t. in 5 bundles 

 at base of corolla with long glabrous filaments. Pod. 3-3£' ; dehiscent, like" 

 that of Sama, but thinner and darker bru^'u, sometimes only 1-2 £", by \" 

 and 1*3 seeded. 



Baker, Brandis and Prain state that the corolla in Catechu is 2-3- 

 times tho length of the calyx (and giye the number of pinnae and lflts. 

 as very much greater). Baker also states tbat the flowers of, Catechu are 

 of a darker yellow than those of A. Suma. The specimens examined by
