colour, especially the infolded lobes of the labellum, which are some- 

 times purplish. It was not introduced into European gardens till 

 1840, when Thomas Lobb sent plants to the Exeter Nursery. 



The variety occurred as a single plant among an importation of 

 Cypripedes from North Borneo, in 1858, by Messrs. Low and Co., 

 from whom it was acquired shortly afterwards by the late 

 Mr. John Day. There is no record of its having been imported 

 since. 



O. Lawrenceanum.

Cypripcdium Lawrenceanum was discovered by Mr. F. W. Burbidge, 

 in 1878, during his mission for us to North Borneo. It occurs on 

 the left bank of the Lawas River, near Meringit, at an altitude 

 of 1,000 — 1,500 feet, growing in company with the beautiful little 

 dwarf palm named P inanga Veitchii. In this locality the Cypripede 

 is found chiefly in the shady forest, growing in the layer of dead 

 leaves and other forest ddbris that overlie a substratum of yellow 

 clay ; less frequently it occurs among moss and leaves on limestone 

 rocks. Amongst recent importations several sub-varieties of great 

 merit have appeared, especially the remarkable albino form described 

 above, in which all traces of the purple so conspicuous in the
