black, closely pubescent or finally glabrous ; endocarp: bow, 
The leaves are 3—6 by 1—2 inches, oblong or elliptic, acu 
or subobtuse, base unequal, above nearly glabrous with pub 
scent nerves, beneath hairy and often with tufts of hai 
hollow glands in the axils of the primary nerves. 
sent in the roots, is a very bitter non-crystallizable alkale 
which we have provisionally called Alangine. It is soluble im 
alcohol, ether, chloroform, and acetic ether, and practi 
insoluble i in water. With the mineral acids, and with ace 
it occurs as a yellowish, varnish-like deposit wholly dest 
of any crystalline structure. From an acid solution it is 
cipitated in white flocks by the addition of alkalies, and 
the ordinary alkaloidal re-agents it affords marked precipit 
With concentrated sulphuric acid, alone or with the addition 
of potassium bichromate, no special colour reactions 
observed. Fréhde’s re-agent gave an indigo-blue colorati 
the cold, and on gently heating and then cooling a very lig 
brilliant blue resulted. With nitric acid a reddish hb 
solution was yielded, and on gently warming it nitrous fam 
platinum salt was prepared which contained 20-703 per 
of platinum on the salt dried at 100° C.
