Zee ncidium Luridum does not often appear in cultivation. In a state of 
a 
nature, however, it is one of the species most widely dispersed. The 
first plant which was introduced in Europe, the one described by 
LInNE, was a native of Jamaica. Since that time, the species has been disco- 
vered in the West Indies and the neighbouring regions of Continental America, 
South America, Central America and South Mexico. 
It is all the more surprising not to see it figure in every collection, that 
it is a very decorative plant, the flowers being of a good size and prettily tinted. 
The coloration varies greatly; this is very frequent with Orchids which are 
dispersed over a wide surface. This fact has even induced some authors to 
suppose that in a state of nature there has been intercrossing between O. Luri- 
dum and two other forms closely allied to it, O. haematochilum and O. Lanceanwmn. 
These are mysteries difficult to solve; it is certain, however, that one of the 
varieties ascribed to the former, the intermedium variety, reminds us very 
strongly of the coloration of O. Lanceanum. 
The most common type has clawed sepals and petals, margins undulated, 
of a dull yellow or brownish colour blotched with yellow, the lip three-lobed, 
with small, rounded lateral lobes, the front lobe forming a short broad claw, 
then transversely oblong emarginate in front. The crest is yellow spotted with 
red; on each side a small round rose tubercle; the wings of the column rounded 
kidney-shaped, are rose in colour. 
Linné had classed this species with the Epidendrum genus, like all the 
Orchids known in his time. When it was re-introduced subsequently and flowered
