MAXILLARIA ELEGANTULA, Rolfe.—A species introduced with M. 
Sanderiana, Rchb. f., by Messrs. F. Sander & Co,, and flowered in their 
establishment, at St. Albans, in October last. It is allied to M. grandiflora, 
Lindl., and has the sepals and petals nearly white at the base, and brown- — 
purple towards the apex, spotted with dark purple-brown; and the lip 
yellow margined with purple at the base.—.c., p. 196.

but with smaller white flowers, which are veined and suffused with light 
purple on the lower half of the petals, and the lip margined with the same

albino of the species has since flowered at St. Albans.—l.c., p. 197.
