276 NEW HEPATICE. 



Stems scarcely two lines long, brownish-olive, in a dry 

 state appearing channelled from the recurved margins of the 

 leaves. Lower leaves very small, those of the summit ten 

 times larger ; their texture is dense, somewhat carnose. No 

 fruit present ; hence it may be of a different genus. It grew 

 intermixed with Petalophyllum Preissii, Gottsche. 



10. J. placophylla, Tayl. ; caule laxe csespitoso, erecto, elon- 

 gato, subramoso ; foliis distantibus, erecto-patentibus, 

 tenuissimis, scariosis, oblongis, obtusissimis, complanatis, 

 margine subundulato, integerrimo; stipulis majoribus, 

 cordato-obovatis, integerrimis.

Jameson. 



Shoots 2-3 inches long, olive brown, flat. Leaves and 

 stipules distant, their outline irregularly indented, their tops 

 either rounded or sometimes retuse, quite entire. This has 

 the habit of J. palustris, Hook. fil. et T., from Cape Horn; 

 but the leaves are more distant, quite flat, and neither round 

 nor so plicate. 



11. J '. paupercula, Tayl.; caule sparso, tenuissimo, repente, 

 subramoso ; ramis elongatis, simplicibus ; foliis distantiori- 

 bus, minutis, oppositis, erectis, semicordatis, concavis, 

 integerrimis; stipulis bipartitis, segmentis filiformibus, 

 articulatis, utrinque exterius basi unispinosis. 



Hab. Creeping on Sendtnera pruinosa, Tayl. MSS. in woods 

 of Pichincha, near Quito, 1845. Prof . W. Jameson. 

 Stems finer than human hair, blackish, shining when dry; 

 shoots simple, sometimes three inches long, to the naked eye 

 resembling a fine thread with minute knots at regular intervals. 

 Leaves slightly decurrent, the dorsal margin incurved. Sti- 

 pules unconnected with the leaves. Close to the stipules 

 arises a lanceolate cluster of rootlets by which the plant at- 

 taches itself for support. No fruit observed. This reminds 

 one of Plagiochila Brauniana, Lind., but the stems are finer 

 and longer, while the presence of stipules is at once dis- 

 tinctive.
