specimens witli a petiole 2 ft. long and nearly V diam. at its base 

 arising from the centre of the tuber. Peduncle arising from one side 

 of the tuber only 1-2" long in flower, 2-3" long in fruit, green and 

 spotted. Spathe 7-20" long, tubular portion not much differentiated 

 from the limb and often more or less open (at intervals) down to the 

 neuter inflorescence which is soon crowded with dead flies, limb 

 linear-lanceolate, leathery, greenish or yellowish with purple blotches,, 

 margins usually purple, waved, apex with a short cusp. Spadix 

 rather slender, ovaries occupying about -5" at base with clavate 

 neuters just above, then a smooth purple space for 1-5" above w^hich 

 is the male inflor. only -5" long with a smooth grey or purple terete 

 appendix above.

 lateral mts. 2-5 each .side not cut quite to the rhachis except the last and smallest of 

 the pedate sy.stem Avhich is sometimes shortly petioluled and only ^-5" long, others 

 with very broad base and shortly acuminate tip, shining and glabrous both sides 

 paler beneath, sec. n. translucent very numerous uniting in an intra-marginal one 

 Irom which again nervules radiate and again unite in a second intramaro-inal 

 nerve : some of the sec. n. are forked or form a few large areoles by intermediate 

 nerves. Fruiting head ro-2 5" diam. subglobose with globose or clavate white 

 receptacle. Berries reddish of more or less hexagonal prisms -4" long, flattened

Tuberous herbs Avith 1-2 leaves 3-sect or pedatisect or pedately 

 compound or with whorled leaflets. 8pathe cofetaneous deciduous, 

 convolute at base, with the limb variouslv shaped often very broad, 

 usually incurved at the tip. Spadix included or exserted, appendacre 

 various, sometimes Avith a disc-like sweUing at base, often excessively 

 long and filiform. Flowers usually dioecious. Fem. fl. densely 

 crowded at the base with sometimes a few neuters above them, ovary 

 1 -celled with short or style and disciform stigma. Ovules 2-8 

 basilar, orthotropous. Male inflorescence of sessile or stipitate 

 synandria each of 2-,5 stamens with cells opening by pores o/ slits, 

 sometimes neuters above them and neuters sometimes continued on 

 to the appendage. Berries 1-few-seeded. Seeds albuminous Avith 

 axile embryo. 



A very interesting genus of very numerous species, chiefly Himalavan The 

 appendage sometimes ends in a filiform thread several feet long, trailino- on the 

 ground or caught up on other plants. I have found no explanation of this curious
