ONCIDIUM KRAMERIANUM. 
The imitative forms of many plants and insects are well 
known, and are in no tribe of plants more remarkable than in 
the orcliidacese. Even amongst our native orchids this is seen, and 
the bee and fly orchis are known to those lovers of wild flowers 
who ramble over our chalky downs ; the beautiful Peristeria or 
dove plant is another example of this, but perhaps in none is 
it more remarkable than in the species Oncidium Papilio and 
Papilio Major. Few persons for the first time admitted into an 
orchid house where these are in bloom, and ignorant of their 
existence, but would be ready to exclaim, “ What a fine butter- 
fly !” Flowering at the end of a slender stem four or five feet long, 
and fluttering in the draught of the opened door, it is so very 
like the insect from which it derives its name, that a person 
might well be pardoned for the mistake. 
Oncidium Kramerianum, one of the many introductions of Mr. 
William Bull, is a species differing considerably from the older 
species, and coming from a different locality, viz., New Granada, 
while Oncidium Papilio is, we believe, exclusively confined to 
the West Indies ; the main difference being in the fringe that 
surrounds all parts of the flower, especially the lower lip, and 
the colours being much brighter. In cultivation the same 
treatment will be successful as that adopted for 0 . Papilio. 
All lovers of orchids would do well to visit Mr. Bull’s esta- 
blishment, as he has recently erected what may well be described
