grown together at the edges as to form a kind of cup, capable 

 of holding water. But it differs in the colour of the flowers, 

 which are pure white, not green, in their scent which is aro- 

 matic and not fetid, and in their size, for they are larger ; 

 the edge of the cups of the stem is quite smooth and pellucid, 

 not fringed with a coarse short hairiness ; the labellum has 

 a sharp-keeled back, is inflated, and the apex is reflexed, 

 all which circumstances are at variance with S. cucullatum ; 

 finally the dorsal lip of the stigma of the latter species is 

 short, linear, and emarginate, while in S. candidum it is 

 short, round, and entire. These are not all the distinctions 

 between these species, but they are abundantly sufficient to 

 enable Botanists to recognize them ; in a dried state they 

 are easily confounded. The first knowledge I had of this 

 species was from the collection of M. Drege, who found it 

 near Gnadenthal and Riebokscasteel ; I afterwards met with 

 it in Sir W. Hooker's Herbarium, from Mr. Harvey. It 

 appears from the specimens sent home by the latter Botanist, 

 that its cups are occasionally enlarged into leaves, a circum- 

 stance which also happens in S. cucullatum itself.

Of this lovely plant I have also received fresh specimens, 

 through the kindness of Sir John Herschel. The flowers 

 are of a deep clear rose colour, melting into white, and 

 richly spotted with purple in the throat ; they smell like 

 sweet-vernal grass. I know no Orchidaceous plant prettier 

 than this. 



It is particularly deserving of notice that the first of these 

 species was planted in the open ground in May last ; and that 

 it was under such circumstances that the fine specimens I 

 examined w T ere produced. Upon this subject Sir John 

 Herschel has favoured me with the following note. 



" The specimen of S. candidum was flowered in a box of 

 bog earth, openly exposed, except in heavy rains when it 

 has been taken in ; and in cold nights has been protected 

 by mats. But there are also several specimens of the 

 S. candidum now flowering in an open bed under a south
