May, 1903.] THE ORCHID REVIEW. 137 
celebrated collection of Norman C. Cookson, Esq., Oakwood, Wylam-on- 
Tyne, the photograph having been takenand sent to us by Mr. H. J. Chapman, 
Mr. Cookson’s able gardener, together with the one shown on the .present 
page, the whole forming a very remarkable series. 
Puaius WALLICHI, the upper central figure (fig 28), is too well known 
to require description, and is readily distinguished from its allies by its 
rather long curved spur, which is well shown in the figure. The sepals 
and petals are tawny brown in colour, both back and front, and the lip 
Fics’ 33;< PRAIUS X: CLive: 
white, with a yellow throat, and more or less purple staining on either side. 
It is rather widely distributed in the lower Himalayan zone, from Nipal to 
Assam and Burma, and is often cultivated under the name of P. Sanderi- 
anus. 
P. SIMULANS, the lower central figure (fig 30), is a very beautiful 
Madagascar species, which for many years usurped the name of P. 
tuberculosus, on account of the great similarity between the flowers of the 
two species. The mistake was only detected when the true plant first 
flowered in cultivation, about two years ago (O.R., ix, pp. 41-44, fig. 7).
