ONCIDIUM TNSLEAYII. 
which our drawing was taken bore a raceme of a decidedly half-drooping charac- 
ter, as partly show^n in the figure, and better exhibited by the wood engraving. 
The flower-stalk will there be 
seen to issue in a graceful 
curve, and to depend in a very 
elegant flowing manner. 
As we have remarked in a 
former number, the species was 
originally thought to be identi- 
cal with Odontoglossum grande^ 
on account of the partial re- 
semblance of their pseudo- 
bulbs, but even in this par- 
ticular a practised eye will 
easily detect a difference be- 
tween the two plants, if both 
are in a perfect and fully 
developed state. The pseudo- 
bulbs of 0. grande are larger 
and with a greater tendency to 
roundness ; while those of 0. 
Insleayii are more concave on 
one side, and with sharper edges. In the flowers, the latter plant is far inferior 
to 0. grande^ except in the colours of the labellum, where it has a manifest 
pre-eminence. 
By a comparison of our excellent of the two species, (0. grande being 
figured at p. 49 of the present volume,) the chief distinctive features of the 
inflorescence will be at once manifest. The colours, the forms of the wings of the 
column, of the tubercles and appendages of the labellum, and of the latter organ 
itself, are essentially remote ; and 0. Insleayii comes much nearer to 0. papilio, 
with which, again, it can never be confounded, from the striking peculiarities of each. 
Messrs. Loddiges cultivate it on a block of wood, keeping it in the warm 
orchidaceous-house, during summer, and removing it to a cooler and drier place 
when its new pseudo-bulbs are perfected, which will be towards the month of 
November. Here it will most likely flower about February or March ; at least, 
that is the period at which it blossomed with Mr. Barker.
