LEGUMINOS #-MIMOSEA. 43 
from the hot districts of America. The flowers are very variably 
arranged on the stems.’ 
Calhandra,’ on the contrary, has decompound bipinnate leaves, 
though with the flowers of Jaga. But the fruit is a straight or 
somewhat bowed pod, whose two valves separate elastically, the 
apex bending back towards the base. The stamens are usually very 
numerous, rarely only ten or fifteen in number. Some eighty species 
of this genus are known,’ trees or shrubs from tropical or sub- 
tropical Africa; one species‘ is found in India. The flowers are 
always grouped in capitula (fig. 36), terminating axillary peduncles 
or collected into terminal racemes. 
Lysiloma,’ with the habit of Mimosa, and the oligandrous flowers 
of Calliandra, has bipinnate leaves, and an inflorescence of capitula 
tube common to the base of the androceum and 
the corolla, and will tell us whether it be not of 
receptacular nature. It was no doubt this 
arrangement that led A. RicHarp to refuse 
to consider as a calyx the organ generally 
known as such and inserted considerably below 
the petals and stamens. 
The pollen of Inga anomala has been de- 
scribed by H. Mont (Ann. Sc. Nat., sér. 2, iii, 
230, 342, t. xi. fig. 43), as having each mass 
composed of eight grains placed on a single plane 
and porous at the angles, with a lot of little 
viscid cells collected at the point of the mass. 
There are eight masses in each anther, and the 
point of each looks towards the centre of the 
cell. 
! The inflorescence is the chief character 
employed to group the species (some hundred 
and fifty) of this genus into sections. BENTHAM 
admits the five following :— 
I. Euinga.— Flowers collected into lax 
oval spikes, short or elongated, interrupted 
towards the base. Flowers large or very large, 
sessile or shortly pedicellate, villose or tomentose. 
Calyx campanulate or tubular. Pods thick with 
dilated edges, often even broader than the faces 
of the valves. Species about fifty (VELLOZ., 
Fl. Flum., xi. t. 3, 12, 14, 21.—Vaut., in dct. 
Soc. Hafn., ii. t. 10.—K., op. cit., t. 11-14.— 
Hoox., in Bot. Mag., t. 5075). 
II, Pseudinga.—Inflorescence of  Hwuinga. 
Flowers a fair size, sessile or very shortly pedi- 
cellate, glabrous or pubescent. Calyx of Huinga. 
Pod flattened, .usually pretty broad, with 
very thick edges. Species about forty (Vaut., 
Eclog. Amer., iii. t. 24.—PREst., Symb. Bot., 
i. t. 42; ii, t. 58.—LuM., Jard. Fleur, iii. t. 
399). 
IIL. Burgonia.—Flowers sessile, small, nu- 
merous, glabrous, or sub-pubescent, in cylindrical 
shortly pedunculate, usually axillary spikes. 
Calyx campanulate, much shorter than corolla. 
Species about fifteen (AUBL., Guian., ii, 941, t. 
358.—VELLOZ., Fl. Flum., xi. t. 5, 8, 9). 
IV. Diadema.—Flowers sessile or more rarely 
pedicellate, small, narrow, glabrous. Inflores- 
cence of globular capitula, with long peduncles. 
Species about ten (VELLOZ., op. cit., xi. t. 44, 
45.—SEEM., Bot. Her., t. 23). 
V. Leptinga.—Flowers with slender, well 
developed pedicels, usually longer than calyx, 
unless this be very large; small, glabrous, 
rarely pubescent, in umbels, on sub-globular 
receptacles. Species about twenty (VELLOz., 
op. cit., t. 10, 27.—Pa@rp. & Enpu., Nov. Gen. 
et Spec., iii. t. 289).
