be the same as is practised with other tropical plants of this 
very extensive order. 
Any of the back pseudo-bulbs, such as are represented 
in the plate, by being taken off will form plants, but the front 
ones are by far the best. 
This genus is now so extensive, that it is difficult even 
for those most familiar with the species to avoid errors in 
publishing what are supposed to be new ones. I therefore 
may be permitted to observe, not for the purpose of criti- ~ 
cizing, but for the sake of preventing, if possible, the incon- 
venience of multiplying names, that the M. Henchmanni of 
the Bot. Magazine, t. 3614, is one of the forms of M. varia- 
bilis. M. pumila of the same work, t. 3613, is so very near 
M. uncata, that although from the figure it seems different, 
it is desirable to re-examine it, and I shall be glad to receive 
it from some of my correspondents.
