Hab. South Sea islands, where we believe it was first found by Mr. 

 Forster, during the celebrated voyage round the world with Captain 

 Cook. Isle of France, Auhcrt du Petit Thouars. 



This species is very remarkable for the curvature of its fruitstalk, 

 which is bent down at the top like the neck of a swan, and at that part is 

 beautifully crested with membranaceous scales. These scales exist, 

 though of a smaller size, and regularly imbricated, upon all the rest of 

 the seta, which is of a succulent nature, much resembling that of a 

 Sphagnum, and swelling out into a small bulbous base. The substance 

 of the leaves is remarkably succulent, that of the perichaetial ones mem- 

 branaceous, nerveless, and ending in a long acumen. The capsule is 

 rich brown, and beautifully reticulated; the lid we have not seen. The 

 calyptra is large, companulate, whitish, rigidly membranaceous, multi- 

 fid at the base in the same manner as that of Daltnnia splachnoides ; 

 its segments very narrow, pellucid and rigid, resembling, when highly 

 magnified, the quill portion of a feather, its upper part is hispid. Some 

 specimens which we have received from the Isle of France, of a Hooheria 

 without f ratification, seem exactly to coincide with the character of this 

 species. The plant which Bridel has called Pterygophyllum asplenioi- 

 des, and which was sent to him from the Isle of Bourbon, appears also to 

 be H. cristata. 



15. H. Parkeriana, caule elongato, ramis complanatis, fo- 

 liis imbricatis subbifariis oblongis acutis undulatis apice serru- 

 latis nervis duobus fere ad apicem attingentibus, capsula 

 oblonga horizontali, calyptra laciniata. Pl. V. 



Hab. Upon trees in Demerara, C. S. Parker, Esq. 



This noble moss, which in its habit much resembles Neckera crispa, 

 especially in the form, size, and disposition of its foliage, we have named 

 after its discoverer, our excellent friend C. S. Parker, Esq. of Blochairn, 

 near Glasgow. The stems creep to a great length, and are bare of 

 leaves; the branches are irregularly pinnated, two or three inches long, 

 and, including the leaves, a quarter of an inch broad. The fruitstalks 

 are numerous, about an inch and a half long ; the capsule oblongo-pyri- 

 form, horizontal ; the calyptra quite glabrous. 



Hi. II. undata, compressa, foliis imbricatis ovato-lanceola- 

 tis longe acuminatis versus apicem undulato-crispatis serratis- 

 que, nervis duobus ultra medium evancscentibus, " capsula 

 ovata, operculo longe conico." Yh. V.
