This is another of Colonel Benson’s remarkable dis- 
coveries, communicated to Messrs. Veitch, and flowered by 
them in April of the present year. Tt is a native of the 
same localities as Dendrobium crystallinum, aftects in the 
‘Arracan mountains, growing in sheltered and shady spots 
to its discoverer) difficult, 
on large trees, and 1s (according 
when out of flower, to distinguish from /. Bensoni (Tab. 
Nost. 5611). Dr. Reichenbach, its describer, indeed, justly 
compares it with /. Bensoni in many points of structure, 
though differing so remarkably in the breadth and two-lobed 
d colour of the 
lips of the leaves, in the form of the raceme an 
flowers. ‘The species was dedicated by its namers to Lady 
Londesborough, “ in appreciation of Lord Londesborough’'s 
great and generous love of Orchids.” The comparison of the 
terminal lobe of the lip to a blackcock’s tail by Professor 
Reichenbach is a happy one- 
Duscr. Stem short in the only specimen I have seen. 
Leaves strap-shaped, six to ten inches long, by two-thirds or
