378 NEW HEPATICiE. 



II ad. Java, in Prov. Buitenzorg. 1843. Dr. Miguel, Herb. 

 Hook. 



Patches creeping among Musci, very pale olive-green. 

 Stems about 1 inch long, subbipinnate. The lobule, on the 

 full grown stems, is amplexicaul, and has a patent summit, 

 and exteriorly a deep sinus, which is sufficient to sepa- 

 rate this species from our R. recubans, independent of the 

 more ovate leaves. 



9. R. retroflexa, Tayl. ; caule implexo, procumbente, ramoso; 

 foliis subimbricatis, patenti-reflexis, oblongis, apice rotun- 

 datis, integerrimis ; lobulis erectis, cauli adpressis, subim- 

 bricatis, lanceolatis, obtusiusculis, decurrentibus. 

 Hab. Pacific Isles. Nightingale, Hook. Herb. 



Patches wide, yellowish dusky-olive. Stems more than 1 

 inch long. Leaves recurved from where they join the lobule, 

 rather long. Lobules pointing forwards, imbricated so as 

 nearly to conceal the stems. We have not seen the R. lin- 

 gulata, Gottsche, from Java, but if we may judge of the 

 brief description in Syn. Hepat., ours is closely allied to it ; 

 differing by the decurrent leaves and more lanceolate lo- 

 bules. 



12. Madotheca, Dumort. 

 1. M. squamulifera, Tayl.; caule laxe ceespitoso, adscen- 



dente, vage bipinnato, squamuloso ; pinnis patenti-recurvis ; 



foliis imbricatis, patentibus, subquadratis, ovatis, apice 



recurvis, basi undulatis, integerrimis ; lobulis stipulisque 



oblongis, obtusis, basi processus minutos demittentibus ; 



calyce subsessili, laterali, late ovato, compresso, ore angus- 



tato, denticulato. 

 Hab. Pillzhum, Columbia, 1827. Prof. William Jameson, 



Hook. Herb. ; also in woods at Banos, and in the Forest 



of Esmeraldos, Jameson. 



Tufts wide, brownish-olive. Fronds complanate. Stems 

 6-8 inches long, covered with minute, waved, and involute 

 scales. Perichtetial leaves obtuse, most minutely toothed,
