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 3f . 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.
