A very curious and pretty little species, of which I find 

 no record subsequent to the publication of Uu Petit Thouars' 

 work, cited above, and which was published in ! 822, for, 

 strange to say. it is omitted in Lindley's celebrated ' Genera 

 and Species of Orchidaceous Plants.' 'Hie structure of the 

 flower seems peculiar, owing to the small size of the dorsal 

 sepal, as shown both in Thouars' and Mi-. Fitch's drawings. 

 1 regret not having seen the living specimen, to confirm this 

 character. The name is given in reference to the pale yellow 

 (citron-coloured) flowers, which are scentless. The plant is 

 a native of Madagascar, and was flowered by Messrs. Veitch, 

 of the Royal Exotic Nurseries. Chelsea, in March, 1865. 



Descr. Stem very short, half an inch long, sending out 

 abundance of slender flattened aerial roots. Leaves few, 

 close-set, three to four inches long, oblong-lanceolate, acumi- 

 nate, contracted at the base, smooth, convex, and bright 

 green above, paler below; midrib deeply sunk. Scapr- 

 radical, with the flowering portion twice as long as the leaves, 

 pendulous, very slender, with numerous short, sheathing,
