HAB. Common in Liguanea. 
FL. Throughout the year. 
A shrub, seldom more than 2 feet in height : branches spread- 
ing, subflexuose, angulose and appresso-puberulous towards 
their extremities. Leaflets 4-5-paired with an odd one, petio- 
lulated, elliptic, acute at the base, rounded and apiculated at 
the apex, appresso-puberulous especially beneath. Stipules 
small, subulate. Racemes axillary, not half the length of the 
leaf. Flowers pedicelled, furnished at the insertion with a 
small subulate bractea. Calyx 5-dentate; the two upper teeth 
more widely apart than the rest. Standard ovali-rounded, api- 
culated, not emarginate, tinged with vermilion colour internally, 
minutely ciliated and appresso-puberulous externally: wings 
shorter than the keel, of a vermilion colour, minutely ciliated : 
keel concave, greenish, minutely ciliated. Legume upwards of 
an inch in length, arcuate, terete, appresso-pubescent, with the 
sutures, when dry, callous and slightly prominent: seeds 10. 
This is a very distinct species from the preceding. It abounds 
more in the dyeing principle, and is therefore the one gene- 
rally selected for cultivation. 
The Guatimala indigo plant, I. disperma of some authors, but 
considered by De Candolle as only a variety of the present 
species, though formerly cultivated, is not now to be met with 
in this country.
