_ reticulate-venose; petiole } to 1 inch; racemes copious, ascend- 
4 ing, lateral and terminal, the latter sublax, 6 to 12 inch long, 
simple or with a few short ascending branches in the lower 
part; pedicels p to 4 inch, ascending ; bracts minute, setaceous ; 
calyx under ;'; inch, finely downy; teeth lanceolate ; corolla 
2 to 4 inch; pod falcate, 3.to 3 inch long, jz to $ inch broad, 
_ 6 te 8 jointed, glabrescent, or clothed with minute hooked 
hairs. (Flora of British India.) 
The roots have a soft thick bark and a central woody 
column ; no tannin is present.

The ash contained a trace of manganese. The petroleum 
ether extract was yellowish green, oily, and deposited fine 
_ heedles on standing: it was partly soluble in alcohol with acid — 
q reaction: the insoluble residue was white; no alkaloidal prin- 
_ Ciple was detected. 
4 _ The ether extract was yellowish, had an aromatic odour, and 
_ Contained a trace of oil and resin: it was only partly soluble in 
_ caustic alkalies, with a deep yellow coloration: no alkaloi - 
q principle was present. 3 
The alcoholic extract contained a principle which gave a 
a marked reaction with alkaloidal re-agents: and a yellow resin 
soluble in alkalies and reprecipitated by acids. No reaction 
with ferric chloride. The aqueous extract reduced Fehling’s 
solution; on boiling it gave no precipitate with dilute ee ms 
with ferrocyanide of potassium and acetic acid a ye orsk| 
_ turbidity was produced: mixed with an equal nee ve oe . 
Inte alcohol a very slight turbidity was occasioned: plvm 
acetate and hydro-acetate both gave a white precipitate.
