 base, of a bright light green colour, often with one or two accessory ones from 

 the 'base of the pseudobulbs. Scapes radical, issuing from the axils of the accessory

Odontoglossum Alexandra (crispum) Stevensii, Williams and Moore, supra 



We have had an almost endless variety of finely spotted forms of Odontoglossum 

 Alexandm (crispim), but this, of which we now publish a figure, is one of ^ the 

 most densely spotted forms that have come under our notice. It is also very distinct, 

 not only in the tone of its colouring but also in the character of its markings, as 

 ^•ill be seen by the accompanying plate. For the opportunity of figuring it we 

 are indebted to His Grace the Duke of Sutherland, in whose grand collection of 

 Odontoglossums and other Orchids, at Trentham Hall, Staff'ordshire, it has been 



bloomed by His Grace's most efficient gardener, Mr. Stevens, in whose honour it is 



named, and who cultivates these plants in great perfection, many wonderful exami 



having been exhibited by him at the London Shows. He has, moreo\

been particularly fortunate in obtaining good varieties of th.. — , 



species, the flowers of which are turned to good account in the dinner-table an 

 other floral decorations at the Hall.
