2. L. dichotomum, Sw. ; ■prkaaTy petiole so much reduced that the fork seems 

 almost to spring from the main rachis, secondary 1-2 in. 1., firm, naked ; pinnl. 

 digitate, with 5-6 lobes reaching nearly down to the base, or once or even twice 

 forked ; nit. barren divisions 4-8 or even 12 in. 1., ^-f in. br., the fertile ones 

 contracted, sometimes so much so that the lamina is nearly lost ; the spites 1-2 

 lin. 1., in close marginal rows ; Uzture subcoriaceous ; surfaces naked. — Hk, <£• Gt, 

 t. 55. Beddome, f. 62. L. citcinatum and pedatum, and probably flexnosum, 

 Sw. Ugena, Cav. 



Hab. Cbasan, Hong-Kong, Philippines, Ceylon, Malay Peninsnla and Isles. — "ii, as 

 seems likely, this is L. Jlexuosum, Swz., thai is the oldest spedfic name. 



3. L. diffitatum, Eaton (not PresI) ; fximarj petiole short or obsolete, secondary 

 1 in. or more 1. ; pinnl. palmate, cut down nearly to the base or once forked, 

 the lobes 6-12 in. I., f-1 in. br., the point acute or bluntish, the base narrowed, 

 the edge of the barren ones crenulate or finely toothed ; texture subcoriaceous ; 

 surfaces glossy, naked ; spites 1-2 lin. L, in close rows along the edge of the 

 lobes.— ^ton, i!W. Tt^right ^ Fend. p. 217. 



Hab. Gathered about Panama and in New Granada by Seemann, Cnming, and Hayes, 

 and in Guatemala by Salvin and Godman. Apparently larger and less divided than Uie 

 preceding, which is Presl's digitatum, but very doubtfully distinct. 



4. L. semiAastatum, Desv. ; primary petiole nearly or quite obsolete, secondary 

 1 in. or more i pinnl. once forked, each short-stalked, divisions (in our specimen) 

 simple, ligolate, 6-8 in. 1., nearly 1 in. br. without the spikes, the base unequal, 

 one side very cordate ; texture coriaceous ; surface naked ; spites ^ in. 1., in close 

 rows along die edge of the s^;ments. — ^Ugena, Cav. H. auriculatum, Oav. 



Hab. Philippine and Marianne Isles, Cuming, &c. — ^The sterile pionnles are described 

 as palmate, llie fertile one^ except that they are in pairs instead of being nometoos 

 and anunged pinnately/ are like those oi pirmatifidum. 



5. L. articulatum. Rich. ; primary petiole J-^ in. L, secondary 1 in. or more 1. ; 

 barren pinnl. twice forked, each beu'ing 4 ligulate-oblong segm., which are 2-3 

 in. 1., about \ in. br., blunt at the poin^ very distinctly articulated at the base 

 on a short petiole ; texture subcoriaceous ; rachis and surfaces naked • fertile pinnl. 

 many times dichotomous, the short spites in dense clusters^ which are often 

 almost destitute of lamina. — A. Rich. Fl. t. 15. 



Hab. Kew ZesiaaA. — ^A very well-marked species. 



6. L. trifurcatum. Baker ; primary petiole obsolete or very short, secondary 

 1-lf in. 1.; pinnl. twice dichotomously forked, and each division bipartite 

 nearly to the base, the ult. barren divisions 4-6 in. L, j-J in. br., the point acute 

 or bluntish, the edge crenulate, the petioles not articulated ; texture subcoriaceous; 

 rachis and surfaces naked ; fertile divisions contracted, cut down nearly to the 

 rachis, the short spites in clusters of 3-6 upon the lobes. 



Hab. Solomon Ides, MUneSn, 591, J. G. FafeA/ Louisiade Archipelago, afcftCiproy. 

 — This seems a very distinct species. In one of onr specimens the spikes are 1 to 3 

 together, and the portion of the lamina that supports them is only linear. 



** HiUy-dereloped barren pinnules pinnate. Sp. 7-13. 



7. L. •can Jens, Sw. ; primary petiole very short, secondary |-i in. 1. ; pinnl. 

 4-8 in. l.,_--4 in. br., with a terminal se^m. and 4-5 on each side, which are very 

 variable in shape, usually simple, ovate or ligulate-oblong, with a rounded or 

 cordate base, sometimes hastate or even slightly pinnate below, always articulated 

 on a short petiole, spreading from the rachis at right angles ; texture firm ; sur-
