staminode, and in the coloration of the flower. The 

 sketch of the whole plant given in the Gardener's Chronicle 

 represents the sceptriform raceme, upwards of twenty 

 inches long, with expanded flowers below, followed by a 

 series of many empty bracts above, bearing apparently 

 neither buds, flowers, nor fruit, quite unlike any other 

 orchideous plant known to me. Mr. Rolfe informs me 

 that Messrs. Sander showed him a native dried specimen 

 with thirty-two bracts on the raceme. The fine figure in 

 the Gardener's Chronicle represents a plant with larger 

 flowers than that here figured, much broader petals 

 strongly twisted, and with margins neither undulate, 

 ciliate, nor purple. 



P. Ghartibcrlainianum was imported from Sumatra by 

 Messrs. Sander & Co., and named by Mr. O'Brien in 

 honour of the Eight Honourable the Secretary for the 

 Colonies, who is distinguished no less for his public services 

 than for his devotion to horticulture. The specimen figured 

 flowered in the Orchid House of the Royal Gardens, Kew, 

 in March, 1897. 



Descr. — A very robust, tall species. Leaves eight to

 stout midrib. Scape eight to twelve inches high, dark 

 purple-brown, hairy upward. Raceme many-flowered,

 with spreading hairs, dark red brown. Bracts one and 

 a half inches long, boat-shaped, tips rounded, strongly 

 nerved, green; dark purple at the base, ciliate. Ovary

 densely glandular-tomentose. Sepals green, dorsally hir- 

 sute ; dorsal nearly orbicular, an inch and a half in 

 diameter, margins undulate, ciliate with long hairs, seven- 

 nerved, red-purple in front towards the base, and with 

 red-purple nerves ; lateral sepals connate in an elliptic- 

 oblong blade, smaller than the dorsal, and much shorter
