Willd. 
One of the earliest discovered, but latest imported species 
of the magnificent and now enormous genus to which it 
belongs; remarkable not only for its great beauty and 
the delicacy of the colours and texture of its flowers, but for 
its fragrance, which Wallich well described as exquisite, and 
not unlike that of Olea fragrans. Whilst referring this te 
D. amenum of Wallich, I must enter a caution as to its being 
considered the Limodorum aphyllum of Roxburgh, which has 
been referred to it by Lindley and others. In the first place, 
Roxburgh’s plant comes from a very different locality, 
namely, the Coromandel coast; in the second, it has no pink 
colouring towards the tips of the perianth-segments ; 1n the 
third place, the flowers are solitary; and in the fourth, 
Roxburgh makes no mention of the sweet odour so character- 
istic of this plant. There is a sketch of D. amcnum, 
but of a form with a much narrower (perhaps unexpanded) 
lip amongst Cathcart’s drawings of Sikkim plants preserved 
in the Kew Library, and I find a flower of it in Lindley’s 
Herbarium from Chatsworth, but no good specimens any-
