154 MAXILIARIA. 



A most remarkable Maxillaria as regards the colour of its flowers, 

 iu cultivation at Burford Lodge, whence were derived the materials 

 for description. The variety, a very attractive one, is an albino 

 form and was introduced by Messrs. Sander and Co. through the 

 collector whose name it bears. No locality has been divulged, but 

 as it is said to have been found while the collector was in search 

 of Maxillaria Sanderiana, both species and variety are probably of 

 Ecuadorean origin. 



M. grandiflora. 



Pseudo-bulbs broadly oval-oblong, much compressed, 1| — 3 inches long, 

 monophyllous. Leaves ligulate, acute, 12 — 15 inches long, 1| — 2 inches 

 broad, cuiieate-conduplicate at base, strongly keeled beneath. Scapes 

 stoutish, 4 — 5 inches long ; bracts boat-shaped, acute, keeled. Flowers 

 among the largest in the genus ; sepals and petals ovate-oblong, sub- 

 acute, milk-white ; the sepals 2 inches long, the dorsal one keeled 

 behind, the petals much smaller and reflexed at the apex ; lip broadly 

 oval, obscurely three-lobed, the side lobes incurved, vinous purple, 

 striated ; the intermediate lobe reflexed, thickened and crisped at the 

 margin, light buff'-yellow ; plate of disk grooved, thickened and free 

 at the apex. Column thick, terete, and white above ; yellow spotted 

 with red in front.

var. — Amesiana. 



Flowers larger than the usual forms ; the petals streaked longitudinally 

 on the basal half with rose-pink ; the margin of the side lobes of the 

 lip streaked with broad and short red lines. 

 M. grandiflora Amesiana, Hort. 

 The botanical history of this fine Maxillaria is most obscure, and 

 even its precise habitat is known only to the orchid collectors who 

 sent it to Europe. 



It is unquestionably the Dendrohiuni grandiflorum of Humboldt 

 and Kunth as figured by them in their Nova Genera et Species, 

 Its habitat is there stated to be — 



In radicilius Andium Paraguayensium prope rupem El Pupito, villam 



La Erre et planitiem montanaui Saconduuvensium alt 1060 hexap. 



(6,000—7,000 feet). 



As no such mountains as the Andes of Paraguay are known in 



modern geography, and the other places mentioned are not found
