“ Roots strong, fleshy, round and branched. Stem none. Leaves petioled, 
lanceolate, undulate, coriaceous, dull green, about 23 feet long, suberect, 
set obliquely on the petiole, veined, having an obscure lateral rib or 
nerve near the edge of the leaf; middle rib very strong, prominent and 
round both behind and before. Petioles rising from the centre of the 
crown of the root, where they are very turgid, 6-8 inches long, semi- 
cylindrical, about as thick as the fore finger, with a swollen joint at the 
base of the leaf; and here the cuticle generally becomes wrinkled trans- 
versely, cracked, and brown. Stipules broad at the base, clasping the — 
bases of several petioles, pointed, green, persistent, and becoming torn, 
withered, and white. 
“ Peduncle erect, much shorter than the leaves. Spatha suberect, ovato= 
lanceolate, acuminate, pale green, rather shorter than the spadix. Spa- 
dix round, tapering, about 5 inches long, greenish-white, shortly after 
its evolution covered with globules of a transparent, colourless fluid, 
giving it in most lights a very beautiful silvery appearance. Anthers 
yellow ; filaments white. Germen white, spotted with rose-colour. | 
“ This species I have seen at Kew; but I am not aware that it has any

dry, thick foliage.” —Granam. :
