MAXILLARIA. 161 



which are rounded and incurved ; margin of intermediate lobe revolute 

 and crisped ; plate of disk tongue-shaped. Column trigonal, deep 

 sanguineous red above, white spotted with red-purple below the stigma. 

 Maxillaria Sanderiana, Rchb. in Sander's Heichenbachia, I. t. 25 (no date). 

 Unquestionably the finest of ail known Maxillarias. It was 

 discovered by Edward Klaboch on the Andes of Ecuador at an 

 altitude of 4^000 feet and introduced through him by Messrs. 

 Sander and Co. in 1883 or 1884. It flowered for the first time in 

 this country in the collection of Baron Schroeder, at The Dell, and 

 was exhibited by him at the Orchid Conference at South Kensington 

 in May, 1885. 



M. setigera. 



Pseudo-bulbs sub-orbicular or roundish ovate, compressed, 1 — 1| inch 



long, monophyllous. Leaves shortly petiolate, elliptic-oblong, sub-acute, 



6 — 10 inches long. Peduncles 3 — 4 inches long, sheathed by alternate 



and distichous, slightly inflated bracts that are greenish spotted with red. 



Flowers fragrant ; sepals linear, apiculate, 2 — 2| inches long, the basal 



part milk-white, the remainder light yellow ; petals similar but smaller 



and bent forwards ; lip three-lobed, the side lobes oblong, involute, 



white streaked with purple on the inner side ; the front lobe oblong 



with denticulate margin, reflexed, white with a bright yellow oblong, 



hairy disk. Column triquetral, bent, white above, purple below the 



stigma. 



Maxillaria setigera, Lindl. in Bot. Reg. 1845, misc. No. 38. Rckb. in Walp. Ann. 

 VI. p. 517. M. leptosepala, Hook, in Bot. Mag. t. 4435 (1849). M. callichroma, 

 Rchb. in Walp. Ann. VI. p. 518. 



Introduced from Caracas by Mr. George Barker, of Birmingham, 



in whose collection it flowered in 1844. Two years later it was 



sent by Purdie from northern Colombia to the Royal Gardens at 



Kew where it flowered in 1849, on which occasion it was figured 



and described in the Botanical Magazine under the name of Maxillaria 



leptjsepala, the name by which it is still best known in gardens. 



Sir William Hooker having evidently overlooked Dr. Lindley's 



original description in the Botanical Register published four years 



previously. In its long attenuated sepals and petals it approaches 



M. lepidota and M. longisepala, but in every other character it is 



quite distinct. The specific name setigera, " bristle bearing," refers 



to the bristle-like points of the sepals and petals. 



M. tenuifolia. 



Rhizome ascending, sheathed by pali; brown imbricating scales.
