The typical Odontoglossum Rossii was first introduced to this country from 
Oaxaca in the year 1837, by Mr. Ross, who sent it to Mr. Barker, of Birmingham. 
It appears to grow wild nearly all over the Mexican plateau, and to vary consider- 
ably in its native country. Since its original discovery, it has been sent home by 
various collectors in great quantities and large masses, from amongst which many 
new and striking forms have appeared. It is one of the most useful and charming 
_ of the small-growing Odontoglots, the majority of plants of the recent introductions 
producing finer flowers than the original form. Some very distinct varieties of this 
plant have from time to time appeared, not the least striking of which is the plant 
whose portrait is here produced. It was recently exhibited by us before the Com- 
mittee of the Royal Horticultural Society, and was awarded a First Class Certificate. 
We have dedicated this fine variety to the Hon. F. L. Ames, North Easton, Mass, 
U.S.A., into whose collection the unique plant has passed. 
Odontoglossum Rossii Amesianum is a beautiful dwarf, compact-growing evergreen 
variety. It resembles the typical plant somewhat in habit, having small clustered 
bulbs and light green foliage; it is also very floriferous, producing numerous spikes 
from the sides of its newly made bulbs, which bear two or three flowers on each 
spike. The sepals are greenish white, spotted and barred with chestnut-brown, the 
petals being white, with a large chestnut-brown area at the base. It blooms during 
the months of April and May, and continues in beauty fully six weeks. 
We find this section of the genus Odontoglossum thrive best when grown lon 
shallow pans or small baskets, and suspended from the roof in a position which 
affords them all the light possible. Naturally, it grows on stunted trees by the
