From Bot. Mag.:
Plants of this very fine and singular Cattleya were sent by Robert Smith, Esq., of Oaxaca, Mexico, in 1838, to the noble collection at Woburn Abbey, where they blossomed in April, 1839. The bulbs and foliage are remarkable for their very glaucous, or sea-green hue ; and the fine flower, when seen in such a manner that the labellum is not brought into view, has, at first sight, so very much the appearance, not only in regard to form, but to size and colour, of the wild tulip of our country, (Tulipa sylvestris,) that we were for a moment deceived by it. These flowers are scentless.
