LEGUMINOSJE. 305 



HAB. Pastures, &c., common. 



FL. Throughout the year. 



Stem suffruticose, procumbent, coloured. Leaves sometimes 

 conjugato-pinnated. Petioles and peduncles hairy. Calyx 

 3-4-fid. Corolla O Filaments 4, six times longer than the 

 calyx, erect. Style somewhat shorter than the filaments. Le- 

 gume with the disk glabrous, and the margin setose with stiff 

 hairs. 



This species is considered to have originally been indigenous 

 to Brazil : it is, however, very common in every part of this 

 Island, and found to be a very troublesome weed in pastures, 

 from the prickles wounding the mouths of the stock, when they 

 are feeding where it grows. The leaves, like those of the pre- 

 ceding species, are very sensitive. 



3. Mimosa asperata. Shrubby Sensitive-plant. 



Leaves bipinnate, pinnae 8-12-jugate, leaflets multi- 

 jugate with the under surface and margin appresso- 

 setose, prickles of the stem and between the pinnas 

 slightly hooked, those at the base of the pinnae 

 straight, peduncles subgeminate length of the head.

FL. Throughout the year. 



A shrub, about 6 feet in height : branches hairy. Heads of 

 flowers globose, of a pale pink colour. Legumes about 4 inches 

 long, and \ an inch broad, pilose, separating, when ripe, into 

 joints, corresponding to the seeds in number. 



Browne calls this the thorned sensitive from Panama, and 

 states that it was introduced from the Continent. I have fre- 

 quently met with it in gardens, but never growing wild. The 

 leaflets are sensitive to the touch, but the petiole is not, as in 

 the two preceding species, affected. 



XXXVI. INGA. 



Flowers polygamous. Calyx 5-toothed. Petals 5, 

 united into a 5-fid corolla. Stamens co, exserted, 

 shortly (sometimes for the greater part of their length) 

 monadelphous at the base. Legumes broad-linear, 

 compressed, 1 -eel led : seeds covered with a pulp, or 

 more rarely with farina or a pellicle De Cand. 



Trees or shrubs, generally unarmed. Flowers spiked or 

 capitate, red or white There is a very lofty tree of INGA
