tion are hardly surpassed in health by anybody’s. Arpp- 
phyllum is reported to exist there, with many new species 
from Oaxaca. 
Mr. Skinner, who discovered the species, has been so kind 
as to give us the following information upon that subject. 
“ The Oncidium microchilum 1 first found on the top of 
the ‘Cuesta’ of Puentezuelas, some thirteen leagues from 
Guatemala, and sent it to Mr. Bateman in 1838. It was 
growing on a bare rock, with a quantity ot dead leaves and 
grasses about its bulbs, and its roots woven into the interstices 
of the rock and mould about it ; very much exposed to the 
sun, except during the middle of the day, when a ledge of 
rock seemed to afford it a little shade. I afterwards found 
it in great abundance on the rocky hanks of the river Micha- 
tayal, from whence the present one now flowered came ; it 
was sent to Mr. Harter and Mr. Clowes in 1840, and arrived 
in June of that year. I never saw it except in such situations, 
generally exposed, and always among rocks. It is very 
fragrant ; and in its native habitat I have always observed 
the sepals and petals darker and more marked than this now 
flowered here. The temperature generally of the above habi- 
tats is 68° to 70° ; and, from being exposed, cold at nights.”

of the same part. 
It may be potted in turfy heath-mould, mixed with a few 
pieces of small potsherds, which will cause superfluous water 
to pass off' freely . The pot should be half filled with potsherds, 
broken smaller towards the top, and the soil considerably 
elevated above its brim. During the summer months, while 
the plant is in a growing state, plenty of water should be 
given, and the temperature allowed to rise to 80° by day, and 
fall to 68° at night— giving a slight shade in bright sunny 
weather. In the winter season very little water is required, 
and the temperature may be allowed to fall as low as .50° 
or 55 °.
