faces naked or nearly so ; spikes 1-3 lin. 1., in close rows along the edge of the 

 segments. Beddome, t. 61. 



Hab. South China and Himalayas to Queensland, Malay Isles, and Ceylon ; Guinea, 

 Coast. L. micropkyllum, Br., is a common form with short broad segments ; L. semi- 

 bipinnatum, Br., the form with the segments pinnate at the base. We do not venture to 

 separate the Mexican L, mexicanum, Presl, which is quite like this in habit, but is said 

 to be not articulated at the apex of the petiole, a character which our specimens leave in 

 doubt. 



8. L. venustum, Sw. ; primary petiole very short, secondary -^ in. 1. ; pinnl. 

 6-12 in. 1., 4-6 in. br., with a terminal segm. and 4-12 on each side, which are 

 simple, ligulate-oblong, the lower ones usually hastate, or pinnate below, all 

 articulated at the base, bluntly lobed at the edge when barren, the upper ones 

 sessile, the lower ones on a spreading petiole ^-^ in. 1. ; texture firm ; rachis and 

 surfaces densely villose ; spikes 1-4 lin. 1., in close rows. L. polymorphum, 

 H. B. K. Ugena, Cav. H. hirsutum, Willd. 



Hab. West Indies and Mexico to Brazil and Peru. Near the preceding, but larger 

 and constantly villose, with the edge of the barren segments crenato-pinuatifid. L. cubense, 

 H. B. K., probably belongs here. 



9. L. volubile, Sw. ; primary petiole nearly or quite obsolete, secondary about 

 1 in. 1. ; pinnl. 8-12 in. L, 6-10 in. br., with a simple ligulate-oblong terminal 

 segm. 3-6 in. ]., 1-1^ in. br., and 3-5 like it on each side, truncate or subcuneate, 

 and articulated at the base, and all distinctly stalked ; texture subccriaceous ; rachis 

 and surfaces naked or slightly pubescent ; spikes 1-3 lin. 1., in close rows along 

 the edge of the leafy segments. L. scandens, Schk. t. 138. (iion Sw.}. L. hasta- 

 tum, Mart. t. 57. 



Hab. Cuba to Brazil. From this we cannot separate by any clear character L. has- 

 tatum a,nd~expansum, Desv., hirtum and lucens, K.aulf., Pceppiganum, Pre^l, Wrightii, 

 Eaton, surinamense, Miquel, acuminatum, puberulum, and micans, Sturm. Segments of 

 several of these are figured by Sturm (Mart. Fl. Bras. fasc. 23. t. 13-14). In some of 

 the forms they have a pair of pinnse at the base, and in others they are slightly villose. 



10. L. pinnatifidum, Sw. ; primary petiole none or very short, secondary often 

 1 in. 1. ; pinnl. 8-12 in. 1., 6-12 in. br., with a ligulate-oblong terminal segm. 3-6 

 in. 1., Jr-f in. br., and 3-4 like it on each side, usually rounded or cordate, all 

 articulated at the base, the lower ones, or all, short-stalked, and sometimes hastate 

 or pinnate below; texture subcoriaceous; rachis and surfaces naked or slightly 

 pubescent ; spikes 1-3 lin. 1., in close rows along the edge of the leafy segments. 

 L. flexuosum, Bedd. t. 63, but scarcely of S warts. 



Hab. Himalayas, Philippines, Malaccas, South India, Ceylon, Angola, Guinea Coast. 

 Here belong L. longifolium and pubescens, Wall., the latter a slightly pubescent form, 

 and L. salicifolium, Presl (a form with small neat long-stalked segments), and Smith's Congo 

 plant, called L. Smithianum by Presl. 



11. L. poly stachy urn. Wall. ; primary petiole short or obsolete, secondary ^-^ 

 in. 1. ; pinnl. 8-12 in. 1., 4-6 in. br. ; the segm. uniform, 9-12 on each side, 2-3 

 in. 1., | in. br., articulated at the base, pinnatind more than halfway down to 

 the rachis into close entire blunt lobes ^ in. br. ; upper segm. sessile, lower ones 

 short-stalked ; texture subcoriaceous ; rachis and surfaces pubescent ; the fruit 

 in the fertile ones occupying the back of the scarcely modified lobes. Hk. 2nd 

 Cent. t. 76. 



Hab. Malay Peninsula ; gathered by Wallich, Griffith, Parish, &c. Well distin- 

 guished by its numerous uniform deeply and regularly piunatifid segments. 



12. L. subalatum, Bojer ; primary petiole obsolete or very short, secondary 

 in. 1. ; pinnl. 6-9 in. L, 4-6 in. br ,*subdeltoid, bipinnate, the apex pinnatifid*;
