So long ago as 1855 a plant was figured in this work as 
Odontoglossum maculatum, which, however, differs widely 
from that species in the size of the flower and in the form 
and colouring of the sepals, petals, and lip, and which is 
the O. cordatum of Lindley. Both these species are natives 
of Mexico, and belong to the same section of the genus, of 
which twelve species are known, including some of the 
finest, which are yet to be introduced into cultivation. 
O. maculatum has been long cultivated at Kew, and 
flowers freely in June. | 
Descr. Pseudobulbs one and a half to two and a half 
inches long, broadly oblong-ovate, compressed, dark-green, 
smooth, one-leaved. Leaves six to eight inches long, 
oblong-lanceolate, acute, about 9-nerved, bright pale-green. 
Racemes a foot long and more, pendulous, loosely many- 
flowered ; peduncle rather stout; rachis flexuous ; bracts 
Spathaceous, shorter than the ovary. Flowers about an inch 
apart, nearly three inches across the petals. Ovary with 
OCTOBER Ist, 1879.
