The Culture of Greenhouse Orchids 



Finally, no Odontoglot lasts less than a fortnight 

 in perfection ; some last four weeks.

 and some so rare that only half a dozen specimens 

 or less are known. Further, there are numberless 

 varieties, differing, as orchids will, from the type,

 a hundred, certainly, are registered ; but some of 

 those long titles represent the single plant known 

 to exist. It is not my purpose to treat of curiosi- 

 ties. Nevertheless, I shall name a few famous 

 varieties of crispum, because they are so often 

 mentioned, in conversation and in print, that the 

 reader ought to know something about them.

 ffunnewellianum, which seems to have sprung into 

 fashion of late at least, it is much more common 

 than formerly at shows. A very striking flower 

 always, though two specimens alike could hardly
