peduncle, the upper obtuse and melliferous. The brim quinque- 
dentate, acute, erect, oblique, unequal. The lowest odd denticle 
longer than the rest ; the upper pair shorter and farther asunder. 
The bottom of the cavity moist with a melleous liquor, including the 
receptacle. 
COROLLA. — Termed papilionaceous, unequal ; the petals ex- 
pressed by distinct names, viz 
Vexillum, the standard; a petal covering the incumbent, greater, 
piano-horizontal, inserted by its claw in the upper margin of the re- 
ceptacle, approaching to a circular figure when it leaves the calyx, 
and nearly entire ; along it, and especially towards the extremity, 
runs a line, or ridge, that rises up, as if the lower part of the petal 
had been compressed ; the part of the petal next to the base ap- 
proaching to a scmicylindric figure, embraces the parts that lie 
under it. The disk of the petal is depressed on each side, but the 
sides of it nearest the margin are reflexed upwards. Where the 
halved tube ends, and the halved limb begins to unfold itself, are 
turn concave impressions prominent underneath, and compressing 
the wings, that lie under them. 
Aire, the wings, two equal petals, one at each side of the flower, 
placed under the vexillum ; incumbent with their margins parallel, 
roundish, or oblong, broader upwards, the upper margin straightcr, 
the lower spreading more into a roundness; the base of each wing 
bifid, the lower division stretching out into a claw, inserted in the 
side of the receptacle, and about the length of the calyx ; the upper 
shorter and inflexed. 
Carina, the keel, the lowest petal, often bipartite, placed under 
the vexillum mid between the also; boat-shaped, concave, com- 
pressed on the sides, set like a vessel afloat, mutilate at the base, the 
lower part of which runs into a claw of the length of the calyx, and 
inserted in the receptacle, hut the upper and side lacinire are inter- 
woven with that part of the al;e that is of the same shape. Tiie form 
of the sides of the carina, is much like that of the aim : and so also 
is their situation, except that they are lower, and stand within them. 
The line that forms the carina, or keel, in this petal, runs straight 
as far as the middle, and then rises gradually in the segment ol a 
circle, but the marginal line runs straight to the extremity, where 
meeting the carinal, they terminate obtusely. 
STAMINA. — Called Diadelphia. The filaments two, of different 
forms, viz. a lower one that involves the pistillum, mid an upper one 
incumbent on it. The former of these, from the middle downwards, 
is cylindraceous, membranaceous, and split lengthwise on its upper 
side; but the upper half terminates in nine subulate* parts, that 
are of the same length with, and follow the flexure of the carina of 
the corolla, and of which the immediate or lower radii + are longer 
by alternate pairs. The upper filament is subularo-setose.J covering
