Tbmpebate HiMAiATAj from Simla, alt. 6-80OO ft., to Sikkim, alt. 

 12-14,000 ft. ' 



Tuher depressed. Petiole 6-12 in. ; leaflets 3-8 in., and as broad, rather mem- 

 branoas. Peduncle shorter than the petiole. Spalhe 3-8 in., narrow, striped with 

 dark purple ; limb suberect or slightl.y incurved, much longer than the tube, tip 

 filiform. — The Sikkim specimens are much smaller than the Nepalese and western. 

 A fine drawing of this made in Nepal by VVallich's native artists is in Kew 

 Herbarium. 



13. A. proplnquum, Schott in CEsir. Bot. Zeitschr. (1857) 333 ; 

 Prodr. Aroid. 29 ; leaves 2, leaflets sessile acuminate, lateral dimidiate- 

 ovate, median rhomboidly orbicular base contracted subpetiolulate, nerves 

 broadly reticulate, limb of spatlie oblong or lanceolate caudate-acuminate, 

 appendage stipitate fusiform above the dilated truncate lobulate base 

 narrowed into a filiform shortly exserted tail. A. intermedium, var. 

 propinquum, Engler Arac. 541. 



Sikkim Himalaya, alt. 12,000 ft., J.D.H., Clarice. 



Eootstoch depressed globose. Petiole very stout, 8 in. long, green, closely 

 speckled and striate with dark green ; leaflets 3-4 in. long and broad, succulent, 

 shining, nerves strong beneath ; basal sheaths long, irrorate with pink purple and 

 green. Peduncle about equalling the petiole. Spathe very like Wallichianum and 

 speciosum ; limb suberect, striped with purple on the sides, reticulate towards the top. 

 Spadias pink. — Described chiefly from a drawing of mine. The shortly exserted 

 appendage seems to be a constant character and a great contrast to its allies. It has 

 been regarded by Bngler as a variety of intermedium, from which the two leaves and 

 rhombic median leaflet distinguish it. 



14. A. costatum, Mart, in Flora (1831) ii. 458 ; leaf solitary, leaflets 

 sessile or snbsessile lateral dimidiate-cordate median broadly ovate all 

 caudate-acuminate, and with very close set parallel nerves, limb of spathe 

 oblong-lanceolate incurved suddenly narrowed into a long filiform tip, 

 appendage shortly stipitate snbcylindric from a dilated lobulate base then 

 narrowed into a very long filiiform tail. Blrnne Humph, i. 101 ; Kunth

Nepal ; WallicTi. 



Tuber depressed, 3-4 in. diam. Petiole 12-18 in., very stout, sheath embracing 

 the stout green peduncle ; leaflets 10-16 by 5-7 in., dark green. Spathe 4-6 in., 

 white striped with dull purple. — Wallich's published figure in Tent. Fl. Nep., and a 

 fine coloured drawing made in Nepal, now in Kew Herbarium, from which it is taken, 

 are the only authority for this species which iu the nervation of the leaves differs from 

 all its congeners, 



15. A. Prazerl, Hooi:. f. ; leaf solitary, leaflets ovate acute or 

 acuminate, lateral subsessile median petiolulate, nerves very slender 

 distant, tube of spathe short, limb much longer oblong-lanceolate acute 

 contracted at the base, appendage slender twice as long as the spathe, 

 base not swollen. 



Uppeb Burma ; Koni, J. C. Prater. 



PLoolstoch tuberous. Petiole 10-18 in., sheathing beyond the middle, or not ; 

 leaflets 3-4 by about 2 in., nearly symmetrical or lateral rather obliqne with rounded 

 or broadly cuneate bases ; median more elliptic, less, acute. Peduncle longer or 

 shorter than'the petiole, slender. Spathe 3^ in., tube 1 in., limb apparently erect, 

 about f in. broad. Male fl. very small, subsessile. Ovaries minute, contracted 

 into a short style with disciform stigma. — A few male fl. occur on the stipes of the 

 appendage.
