The Odontoglossums are amongst the most popular of Orchids. They are not 
only esteemed for their fine showy flowers but for their long lasting qualities, and 
they can nearly all be grown in’ houses with a low temperature. The species 
we now bring before the notice of our readers is a most distinct and desirable one, 
which has been known in cultivation for many years. The drawing from which 
our plate was prepared was taken from a plant that flowered in the collection 
of W. Salt, Esq., of Ferniehurst, Shipley, Yorkshire, who has a grand lot of cool 
Orchids, which are, moreover, exceedingly well cultivated. : 
Odontoglossum maculatum is not only free but compact in its growth. It 
has thick fleshy pseudobulbs, and light green foliage, and the individual plants 
produce their sub-erect spikes of flowers at different times of the year, according 
to the period of the completion of their growth. The flowers are very strikingly 
beautiful, being of a colour that one seldom sees in Orchids, and they continue 
for a long time in perfection when protected against damp. The colour, however, 
varies in different plants. The form originally figured in the Botanical Register 
has the sepals green outside, and chestnut-brown within; that published in the 
Pescatorea has the sepals represented. as brownish purple in front, paler purple 
behind, with green tips on both surfaces; and the form figured in the Floral
