We have had an almost endless variety of finely spotted forms of _Odontoglossum Alexandræ (crispum)_, 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 will 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, Staffordshire, 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 examples having been exhibited by him at the London Shows. He has, moreover, always been particularly fortunate in obtaining good varieties of this invaluable decorative species, the flowers of which are turned to good account in the dinner-table and other floral decorations at the Hall. _Odontoglossum Alexandræ Stevensii_ is one of the bold-habited strong-growing forms of this plant, and as regards its pseudobulbs and foliage resembles any other of the more vigorous forms; like them, too, its flower spikes may eventually branch out into panicles. The individual flowers are of large size, and finely crisped and toothed; the sepals and petals are white, heavily spotted and blotched with pale sienna-brown, and the lip is white, having a large blotch of the some colour on the anterior part, and numerous smaller spots towards the base, where the yellow disk is prominent, and adds life to the colouring. This plant produced its blossoms in March, and continued for six weeks in beauty. Like all the forms of _O. Alexandræ_ it begins to show its flower spikes as soon as the growth is completed. This variety requires the same course of treatment as that given to this class of plants generally, and which is commonly designated and understood as “cool-house” treatment.
