Ammannia. tetrandria monogynia. 427 



those below. Corol one. Pericarp one-celled, one-valved, 

 half covered with the calyx. 



Obs. It differs from A. baccifera in having a capsule of 

 one cell, in being- evalvular, and in the leaves being- lanced, 

 in that species they are linear-cordate at the base, and em- 

 brace the stalk. 



This plant has a strong muriatic, but not disagreeable 

 smell. Its leaves are exceedingly acrid ; they are used uni- 

 versally by the natives to raise blisters in rheumatic pains, 

 fevers, &c. The fresh leaves bruised and applied to the part 

 intended to be blistered perform their office in the course of 

 half an hour or a little more, and most effectually. 



5. A. pentandra. R. 



In the lower part of the plant creeping and simple, erect 

 portion ramous; four-sided. Branches simple. Leaves sessile, 

 lanceolate. Floicers axillary, solitary, sessile, pentandrous. 

 Capsule one-celled. 



A native of moist places ; flowering in the rainy and cold 

 seasons. 



Stems creeping near the base, above erect ; the erect part 

 is branchy, four-sided, smooth, and coloured ; from six to eight 

 inches high. Leaves opposite, sessile, lanceolate, smooth, en- 

 tire. Flowers axillary, solitary, sessile. Bractes two, lan- 

 ceolate, pressing the calyx laterally. Calyx ten toothed, al- 

 ternately smaller and inflected. Corol, petals five, very mi- 

 nute. Stamens five. 



6. A. nana. R. 



Base creeping, erect portion ramous. Branches compound. 

 Leaves wedge-shaped, sessile. Flowers solitary. Capsule 

 one celled. 



A native of such places as the last described, it is consider- 

 ably smaller than that species, but more branchy. 



Stems as in A.pentandra. Leaves opposite, sessile, wedge- 

 foimed, smooth, entire. Floicers axillary, solitary, sessile.
