H.\ b. Chili, Chamisso. 



A very beautiful and distinct species, well figured by Hornschuch in 

 the work above mentioned. We find the denticulations to be of a very 

 peculiar structure, evidently formed of cellules similar to those of the 

 rest of the leaf, sharpened, very acute, and placed with great regularity 

 upon the otherwise even margin of the leaf. 



21. H. depressa, ramis subcomplanatis, foliis laxe imbri- 

 catis oblongis breviter acuminulatis apice serrulatis, nervis 

 duobus infra apicem evanescentibus siccitati crispatis, capsula 

 ovata nutante, operculo conico acuto, calyptra basi breviter 

 laciniata.

Remarkable for its falcato-secund and much acuminated leaves. The 

 calyptra is cleft into broad segments, and is scabrous at the apex. 



23. H. repens, ramis compressis sericeis, foliis subfalcato-

 capsula exigua horizontali, calyptra integra. Pl. V. 



Hab. St. Vincents, Rev. L. Guilding-. 



A small creeping species, with delicate foliage. The leaves are falca- 

 to-secund, especially towards the extremities of the branches. The 

 fruitstalk is extremely slender, with a narrow and oblong capsule, the 

 calyptra glabrous and entire at the base.
