reticulated. Appendage as in A. Qriffithii, of which Clarke {Jowrn. Linn. Soc. xxi. 

 386) considers it a trifling variety. The Bot. Mag. figures, however, uphold the 

 characters which I never failed to observe in Sikkim. Hybrids, of course, may 

 occur. The Western specimens have longer petioles and peduncles and paler greener 

 spathes. All my specimens are 1-leaved, but two are represented in the reduced 

 figure of the Bot. Mag. drawing. 



S. Limb of spathe lanceolate acuminate, or caudate. — Dioecious, except 

 A. Frazeri. 



10. A. speciosum, Mart, in Flora (1831), 458 ; in Wall. Gat. 8923; 

 leaf solitary, leaflets all petiolulate acuminate lateral dimidiate cordate 

 median ovate, nerves broadly reticulate, limb of spathe ovate-lanceolate 

 incurved caudate-acnminate, appendage cylindric or fusiform at the often 

 inflated base, narrowed into a very long filiform tail, base not truncate or 

 disciform. Blume Bumpha i. ] 01 ; Kunth Enum. iii. 18 ; Schott Melet. i.

Boo<s<oc7« oblique, or shortly creeping and rooting; often 5 in. diam. Petiole 

 very stout, green, smooth, often marbled with brown or purple; leaflets 16-19 in., 

 edged with red or purple, median cuneate or rounded at the base; petiolule 

 i-2 in. Peduncle much shorter than the petiole. Tube of spathe 2-4 in., striped 

 with pnrple; limb 2-6 in. long, banded white and purple. Spadix pink or yellowish 

 tail 12-18 in., dark pnrple ; base of appendage usually ovoid ; anther-cells 4-5 ; ovaries 

 ovoid, stigma sessile pulvinate. — Very variable in size and colouring. Schott made 

 three species of it, reduced by Engler to two varieties, both founded on my drawings; 

 they are A. eminens, Schott in (Estr. Bot. Zeitschr. (1875) 357 ; 8i/st. Avoid. 30, 

 simply a gigantic specimen with the spathe 8 in.long ; and A. ndrahile, Schott 11. cc. 

 366 and 31, with an abnormally inflated base of the appendage. Wallich's Arisisma, 

 n. 8925 in fruit, from Tavoy, may be speciosum. 



11. A. mtermedium, Mtime Sitmph. i. 102 ; leaves 1 or 2, leaflets 

 sessile lateral dimidiate-ovate or -cordate median elliptic base acnte or 

 cuneate nerves broadly reticulate, limb of spathe lanceolate incurved 

 narrowed into a filiform cusp, appendage snbstipitate subcylindric 

 narrowed from a dilated fusiform base into a very long fusiform tip.

A smaller plant than A. speciosum, with more membranous sessile leaflets, 

 the median of which is elliptic with a very acute base. From Wallichianvm it 

 differs m the elliptic median leaflet. The nervation at once distinguishes it from 

 A. cosiatum. A. dolosum and Stracheyanum in no way difler from intermedium.
