 (rhizomate) tenui prostrata flexuosa denudata subdivisa iiagelli- 

 fera assurgentes, flexuosi, apice decurvo-circiaati, subsimplices,

bractea connate margine incurve spinis 1-3 armato, auctae. 



Antheridia non aderant. 



J. cenops, L. et G., found by Bertero in Chili, is evidently a close 



ally of /. colorata and grandiflora ; and so are three species, all from 



the Sandwich Islands, described by Austin (Proc. Acad. Nat. Sc. 



Philad., Dec, 1869). Two of these, J. rigida, Aust., and J. coriacea, 



Aust., are roseate ; the third, J. rohusta, Aust., is pale, and has eroso- 



dentate leaves : it should therefore approach J . Carringtoni, but I 



have not seen specimens. 



Before dismissing these " nobiles " of the genus Jangermamiia, I 

 wish to point out that there is a fine group which no one has yet taken 

 up, namely, that of which J. perfoUata, Sw., is the type. In the tall 

 stems, beset with large opposite (and often connate) leaves, which are 

 mostly subtriangular in outline, strongly recurved at the antical 

 margin, and either entire at the apex or very unequally bidentate, it 

 approaches Leioscyphus, the opposite-leaved Lophocolece, and some 

 Plagiochilce ; but differs from them all — much as Diplophyllmn from 

 Scapania — in the turgid pluriplicate perianth, and from the two 

 former in the absence of folioles (except in the involucre). In the 

 perianth, and in the (usually) 10-cleft frill-like involucre, it ap- 

 proaches Jamesoniella, but in all other respects stands widely apart. 

 For this group I claim the rank of a genus, with the following 

 character.
