his elegant little plant is a near ally of the well-known Zy gopetaluim 
maxillare Lopp., of which for some time I thought it might be a 
narrow-leaved variety. But its differences, well marked from the first, 
have proved so constant in character that its claim to specific rank must be 
conceded. It belongs to a small group, of which Z. Gautieri Lem. is the third 
member, whose peculiarity is to grow on the stems of tree-ferns. The present 
species was introduced by Messrs F. Sanper & C°, of St Albans, some years 
ago, but has only been recently described. It is a native of South Brazil, and 
was imported on the stems of Lomaria Boryana. It may be readily separated 
from Z. maxillare and Z. Gautieri by its much more slender creeping rhizome, 
smaller pseudobulbs, and much narrower, grass-like leaves. The racemes are 
erect, and about 5-7-flowered, the sepals and petals light green heavily blotched 
with dark brown, and the lip of a uniform bright purple-blue, with a very large 
horse-shoe-shaped, crest near the base, as in Z. mavillare. The plant here 
represented flowered with M. Atrrep Van Imscuoor, a well-known amateur 
of Ghent, and was exhibited at a meeting of L’Orcuiptenne of Brussels, 
in April last, when it was awarded a first-class Diploma of honour under the 
name Z. Imschootianun.
