than the petals, both being pubescent and bright yellow. 
The pouch is of the same colour but a little darker, with 
a few blotches of crimson in the mouth; it is fully 2in. 
across at the base. The great beauty of this plant has 
induced many collectors to send home quantities of it for 
cultivation, but it has never yet been successfully grown. 
It is said to be almost, if not quite, hardy. A native of 
Mexico, near a town called Irapeo, where it grows at an 
elevation of 5oo0oft.; introduced and flowered in 1846. 
The treatment recommended for C. pubescens is said to be 
the most satisfactory of the many methods tried for this 
Mexican gem.

C. japonicum.—A truly wonderful plant, of which com- 
paratively little is known here. From a mass of roots and 
creeping rhizomes a pair of leaves are developed, much 
in the same way as in C. acaule, but larger, plicate, almost 
fan-shaped, and 4in. across. The scape is rft. high, leafless, 
and hairy; it bears one large flower, in which the ovate- 
lanceolate sepals and petals are 24in. long, greenish, with 
crimson spots at the base of the latter. The lip is 
gigantic, being 24in. long by 1}in. wide, and white, marbled 
with pink; the aperture extends two-thirds of the way 
down, as in C. acaule. C. japonicum was’ known only 
from Japanese descriptions and drawings until it was 
imported from Japan by Messrs. Wallace, of Colchester, 
who succeeded in flowering it in 1875. It is said to grow 
in abundance in moist woods in Japan. The plant which 
flowered at Colchester was planted in light loam in a pot, 
and grown in a cold fernery. Some recommend pure peat 
for it, but, so far as we know, the loam treatment is the 
only one that has resulted in flowers.
