18. L. Lyncei, Tayl.; caule sparso, repente, subsimplici; 

 foliis laxis, erecto-patentibus, lingulatis, subacutis, compla- 

 natis, integerrimis ; lobulis minutis, ovatis, involutis ; sti- 

 pulis nullis. 



Hab. On Diplazium Fraterni, Presl. Martinique, Dr. Gre- 



ville's Herb. 



Stems pale green, scarcely 1 line long ; the leaves as well 

 as the stems sending out fibres terminated by wide discs, by 

 which they radicate. Cellules of the leaves large. In some 

 respects it is allied to L. microscopica, Tayl. but the leaves are 

 flat, slightly incurved forwards, and so remind one of the 

 habit of Schistostega osmundacea, Mohr. 



19. L. longiflora, Tayl.; caule implexo, procumbente, vage 

 ramoso ; surculis subflexuosis, complanatis ; foliis tenuis- 

 simis, imbricatis, patentibus, oblongis, apice rotundatis, 

 integerrimis ; lobulis minutis, ovatis, subunidentatis, invo- 

 lutis ; stipulis rotundatis, planis, apice fissis, subbidenticu- 

 latis ; calyce laterali, sessili, subnudo, ex angusta basi obo- 

 vato, quinquealato, alis subintegris, apice tubifero. 



Hab. Cincinnati, Ohio. Hook. Herb. 



Patches pale dusky-olive. Stems about 1 inch long. Mo- 

 noicous. Perigonial spikes at the base or in the course of the 

 shoots. Perichcetia minute, their leaves erect, scarcely larger 

 than the cauline, the stipular obovato-rotundate, split at the 

 top, the lateral subacute. Stipules rather large. Cells of 

 both leaves and stipules sometimes with an irregular series of 

 minuter cellules around their circumference. From Jung, 

 tabularis, Sprengel, ours may be known by its more obtuse 

 and more imbricated leaves, and by its larger stipules, 

 which are simply split above, but have no divaricating 

 segments. 



20. L. polyploca, Tayl.; caule csespitoso, adscendente, ra- 

 moso ; foliis imbricatis, patentibus, oblongis, acutiusculis, 

 apice recurvis, integerrimis ; lobulis ovatis, erecto-patenti- 

 bus, subunidentatis ; stipulis majoribus late cordatis, bre- 

 viter cmarginatis, integerrimis ; foliis perichaetialibus elon-
