Central America. First comes the present species, inhabiting the mountainous 
region in the neighbourhood of Oaxaca, in South Mexico. Then follows 
O. grande, in the southern part of the state of Guatemala; and lastly comes’ 
O. Schlieperianum, from the mountains of Costa-Rica, still further south. 
O. Insleayi is a rather variable species as regards the colour of the flowers. 
The variety splendens, introduced by Messrs Hucu Low & C?, of Clapton, and 
named in 1868, has flowers rather larger than the type, the sepals and petals 
ochreous yellow, and the lip canary yellow with a broad marginal band of red 
blotches. Var. pantherinum appeared in 1873, and has chestnut brown sepals and 
petals with a paler margin, and the whole of the lip variegated with red and 
yellow. Var. leopardinum has chestnut brown sepals and petals barred and 
margined with yellow, and the lip bright yellow with a marginal zone of deep 
red blotches. The variety awreum chiefly differs in having lost nearly all traces 
of the chestnut markings from the flower. It appeared in the collection of 
Atrrep Witson, Esq., of Westbrook, Sheffield, in the autumn of 1889. The 
variety Imschootianum, here figured, is very similar to the last, and may prove 
not to differ materially from it. It appeared in the collection of M. A. Van 
Imscooot, of Gand, and was awarded a First-class Diploma of Honour at a 
meeting of the OrcHipEENNE of Brussels on October 9 last. LinpLEy’s variety 
macranthum must be excluded, as it is synonymous with O. Schlieperianum. 
The usual time of flowering of this handsome species and its varieties is 
late summer and early autumn.
