tivation by the pure white of its blossoms, and their delicious 

 fragrance. Blume, indeed, says, that the flowers vary from 

 white to pink ; but of the latter hue we have never seen 

 them. Our specimen, here figured, flowered at Kew in 

 April, 1842. 



Descr. Stems tufted, erect, a foot and a half or more 

 long, thickened, or clubbed and furrowed at the base, 

 forming an imperfect pseudo-bulb ; the rest rounded, and 

 gradually tapering to an acuminated point. The lower 

 part has a few remote, sheathing scales ; the middle part is 

 leafy, the leaves gradually becoming smaller, and flowers 

 taking their place upwards. Leaves oblong, obtuse, coria- 

 ceous, distichous, semiamplexicaul at the base, and sheath- 

 ing. Pedicels curved downwards, with sheathing bracts at 

 the base. Sepals and petals oblong, attenuated, pure white. 

 Lip articulated on the very decurrent base of the column, 

 three-lobed, the middle lobe broadly oblong, waved and 

 crenate, pure white, but on the disk is a yellow crest, form- 

 ed of several parallel, crenated lamellae. Column short. 

 Anther-case hemispherical. Pollen-masses as in the Genus.
