We are now about to bring under the notice of our readers one of our oldest 
Orchids, and, withal, one of the most rare. Its foliage is pleasing, and its flowers 
are not only large and showy, but of the most charming character, as will be seen 
from the accompanying representation, for the opportunity of securing which we are 
indebted to Sir Trevor Lawrence, Bart., M.P., in whose well-known superb collection at 
Burford Lodge, one is at all times certain to find a grand display of rare Orchids m 
bloom, such as will well repay a visit. This Zygopetalum makes a grand specimen for 
exhibition purposes; we used to exhibit it many years ago at the Regent's Park 
and Chiswick Shows, with twenty or more of its handsome flowers upon the plant, 
et may add that it was greatly admired. It produces flowers from every 
a and keeps a long time in good condition, so that we could always depend 
Upon it for the May and June exhibitions.
