therefore we retain this name for a genus which certainly claims to be separated as well from LesJcia as from 

 Hookeria.

 Exot. t. 35. Hypnum tamariscinuin, Swartz ! 



Hab. Herrnite Island ; ia wet places on the ground, very common in the woods, forming large green 

 patches (always barren). 



Under Leskia tamariscina two species have been confounded by Hedwig (Sp. Muse. p. 212). The name 

 ought to be applied to the present moss, if the inconvenience of changing names generally received did not forbid.

Our specimens are not so large as those described by P. de Beauvois, though evidently belonging to the same 

 species. Dr. Montague has properly remarked that this species differs from H. laricinum in the flabelliform, not 

 pinnate, disposition of its branches, which all spring from one central point and take a horizontal direction. Fertile 

 specimens from Colchagua, in Chili, have also a more pendulous oblong capsule and shorter operculum.

Caules 1-2 une. longi, graciles, vage parce ramosi ; rami solitarii v. bi-terni, pallide olivacei v. albidi, nunc rivfo-

Allied to the Scottish /. concinnata, Lightf.; but readily distinguishable by the stems not being tufted, the shoots 

 slender and flexile, the larger more cellular leaves, which are far more deeply divided, and have lanceolate seg- 

 ments, and by the cellular stem.
