sub-triternatisected, but simply ternatisected in those of the 

 infant plant ; primary lateral divisions with narrow and erect- 

 patent petiole, divided into 2-3 unequal-sized and petiolulate 

 segments, the outer lateral segment often again dividing into 2 

 shortly petiolulate and unequal-sized small segments ; primary 

 middle division constantly simple, with a long filiform petiole, 

 which is slightly shorter than the segment ; all segments bright 

 green, slightly glaucous beneath, membranaceous, slightly rugose 

 on account of the depressed nervation on the upper surface- 

 triplinerved ; veins loose and erect-patent, with loosely and ir- 

 regularly reticulated veinlets between them ; terminal segments 

 of the middle and lateral primary divisions obovato-orbicular or 

 rhombeo-orbicular, entire and cuneate at the nearly lower half, 

 usually acute at the base, trifid, the midlobe larger than the 

 lateral lobes, all coarsely and unequally crenato-lobed into a 

 few ovate and emarginate lobules, attaining about 4 cm. long 

 3 cm. broad ; lateral segments of the middle and lateral primary 

 divisions smaller than the terminal segment, ovate or elliptical, 

 ovate, obliquely truncate or subcordate at the base, shortly 

 petiolulate, margined with lobules similar to those of the 

 terminal segment. Floral leaves 2, situated on the top of the 

 scape and immediately under the inflorescence, spriously opposite, 

 horizontally spreading, petioled ; the lower one larger and sub- 

 biternatisected, and the upper one ternatisected or sub-biter- 

 natisected ; segments similar to those of the radical leaves 

 in cutting, size, and shape ; common petiole short, 1-15 mm. 

 long, semiterete, canaliculate in front ; vagina short, small, 

 stipulaceous, semiorbicular-auriculate, entire and rounded on 

 margin, often reflexed, 1-2J mm. wide, light green, but 

 membranaceous and whitish towards the margin, sometimes 

 connate with the superior one. Scape erect, springing from 

 the apical portion of the rhizome, much exserted upon the 

 radical leaves, terete, smooth, fleshy, light green with dilute 

 purpurascent hue, about 6-15 cm. long. Inflorescence cymose, 

 bracteate ; the first lateral peduncles oppositifolious and frequent- 

 ly ramose, the secondary lateral peduncles also sometimes again 

 ramose; the pedicel slenderly terete, filiform, drooping at the
