_ We have from time to time figured a goodly number of Odontoglots, which 
are acknowledged favourites amongst Orchid cultivators, since they are not only very 
beautiful, but easy to grow, and do not occupy much space. Many, indeed, that 
we have figured are amongst the most beautiful of their class, and novel varieties 
are continually making their appearance among the successive importations. The 
variety, or form, we now bring before our readers is one of the rarest and most 
beautiful, and one that will be sought after by those who are fond of this particular 
group, and who are on the look-out for fresh forms. 
Our figure was sketched from a beautiful plant in the fine collection of 
J. Buchanan, Esq., Oswald Road, Morningside, Edinburgh, which bloomed very freely 
about May of the present year; this was a most admirably grown specimen, and 
did much credit to Mr. Grossart for the way in which it had been managed ; 
we had, in fact, never seen a finer spike of flowers, and they were 80 beautifully 
arranged on both sides of the rachis, as to make it very effective.
