This is a very distinct species which flowered ae the hablen of 
M. Alexandre Regnier, of pnus nen -bois, Seine, France, in April 
last, having been introduced by him from idcm It belongs to 
the section 1 Pedilonum, but, so far as can be ascertained, is very different 
from any described species. The sepals and petals are very light 
whitish yellow, with several broad stripes composed of innumerable 
purple dots more or less suffused together. The pandurate lip is light ` 
yellow with a faint purple stain on the middle of the front lobe. The 
callus of the lip is peculiar, being a kind of boat-like extension of the 
conduplicate sides of the unguis, and is stained with purple in the 
cavity. ‘The name is given in allusion to the shape of the mentum.
