OvonTocLossum ALEXANDRA WILSoNII, supra. 
This very pretty variety of Odontoglossum Alexandre was imported a few 
years ago among many others. It is really quite surprising how many splendid 
varieties are sent home by our collectors, who, if they were only aware what 
grand varieties were in their various consignments, would in all probability 
stipulate for a much better remuneration than is usually accorded them, for when 
these splendid forms open their blooms they realise a large sum of money, and 
it is on the chance of obtaining such that so many imported O. Alexandre 
are purchased. It is very curious and strange that this species varies so much 
more than many others; O. Pescatorei for instance, which is a species we have 
known longer than it, has certainly produced a few varieties, of which the superb 
form known as Veitchianum is the best, and has wonderfully improved since the 
time when we figured it in Vol. ii., t. 68, yet, as before remarked, these — 
are far less frequent and less beautiful than the forms of Alexandre, which sah 
up out of every importation. The beautiful spotted variety here depicted was 
bloomed in the fine collection formed by A. Wilson, Esq., of Sheffield, who 
possesses many splendid species and varieties of this order of plants, and they are 
well grown and carefully tended by the gardener, Mr. Pidsley. ce 
Odontoglossum Alexandre Wilsonii, like all the rest of the variations of this 
Species, is a compact evergreen variety, resembling the typical plant in its pseudo- 
bulbs and growth. The inflorescence is produced in a similar cermin but the 
flowers are very distinct; the sepals and petals are white flushed with st and 
_ heavily spotted and blotched with chestnut-brown, the lip also being spotted with 
the same colour. This plant thrives under the same treatment as that which suits 
_ the typical plant, that is to say, it should be grown in a pot, and the pot ——
