of which are narrower; and by its longer and more acuminate 

 bract.* G. Curtisii usually flowers in May and June. 



C. Dayanum. 



Leaves elliptic-oblong, acute, 5—7 inches long, variable in colour, 



sometimes pale green with some oblong spots of deep green scattered 



over the upper surface, sometimes tesselated with deep and light green. 



Scapes 8—12 or more inches high, one-flowered. Bract somewhat less 



than half the length of the ovary. Flowers 4 — 5 inches across vertically; 



upper sepal broadly ovate, acuminate, ciliolate, white symmetrically 



veined with green ; lower sepal similar, but smaller and more acuminate ; 



petals ligulate, slightly deflexed, fringed with long black hairs, the basal 



half brownish green, the distal half dull rose-purple ; lip sub-conical and 



compressed at the apex, brownish purple veined with green, the infolded

We are indebted to the late Mr. Day, to whom this species is 

 dedicated, for the following particulars respecting its introduction. 

 It was discovered on Mount Kina Balu, in north-east Borneo, by 

 Mr. (now Sir Hugh) Low, who sent it, together with Nepenthes Rajah, 

 one of the magnificent pitcher plants that has its home on that 

 remarkable mountain,^ to the nursery of Messrs. Low and Co., at 

 Clapton, from whom Mr. Day acquired the box containing the entire 

 stock of both. All the Nepenthes arrived dead, but a few of the 

 Cypripedium plants survived, and one of these flowered in Mr. Dav's 

 collection at Tottenham in the summer of 1860. Cypripedium 

 Dayanum remained a rare plant in British gardens till it was re- 

 discovered at the foot of the Marie- Parie Spur of Mount Kina Balu, 

 by Mr. Peter Veitch and Mr. F. W. Burbidge, during their mission 

 to that region for us in 1879. The first introduced type is distin- 

 guished by its pale green sparingly spotted foliage and somewhat 



* It is evident from the above comparison that should intermediate forms, other than those 

 obtained by the hybridist, hereafter appear that break through the scarcely specific distinctions 

 pointed out in the text, Cypripedium ciliolare, C. Curtisii and C. superbiens can then be only 

 regarded as existing geographical expressions of one once widely distributed species. 



+ It had been previously named Cypripediv/m Dayanum by Stone, Mr. Day's then gardener.
