HAB Cultivated in the plains. 
FTj. Throughout the year. 
Herbaceous, afoot or more in height, somewhat twining; 
branches subterete, anguloso-sulcated, glabrous. Leaflets ovate 
or oval, obtuse, apiculated, nerved, reticulato-venose, subgla- 
lirous (minutely ciliated and strigose on the under surface of 
the nerves) : petiole elongated, sub-3-gonal, striated. Stipules 
oblongo-ovate, auriculato-extended at the base, membranaceous. 
Peduncles axillary, longer than the leaf, anguloso-sulcated, 
bearing in a head about G sessile flowers in pairs, with a 
rounded tubercle between each, at its extremity. Calyx tubu- 
lose, to the glass rough, spotted with purple; upper lip bifid, 
with the divisions subulate ; under lip 3-fid with the divisions 
spreading, lanceolato-ovate. Standard roundish, slightly emar- 
ginate, sulcated towards the base, and furnished with two pairs 
of diverging callosities, externally greenish, internally pale 
yellow; wings tinged with lilac, irregularly obovato-oblong ; 
keel bifid at the base, coherent above, and also below the apex. 
Stamens diadelphous: anthers yellow. Ovary linear: style 
bearded beneath for half its length : stigma hispidulous, bearing 
a conical glandule on its back. Legume 6-8 inches long, 
cylindrical, when ripe of a clay-colour, many-seeded: seeds 
size of a very small pea, nearly spherical, white, with a black 
hilum. 
This is a very prolific and excellent variety of the pulse 
kind. When used green it is scarcely inferior, and when dry, 
is in the opinion of many, superior to the pea of Europe. 
XXVI. Lablab. 
Calyx campamilato-tubulose, 4-fid ; upper lip broad, 
lower of 3 acute lobes. Standard sulcato-channelled, 
with 4 parallel callosities : keel curved at a right 
angle. Stamens diadelphous. Style bearded be- 
neath : stigma terminal. Legume piano-compressed, 
tuberculoso-muricated along the sutures, with cellu- 
lose interstices separating the seeds : seeds 4, or
