more acuminate than those of 0. maculatum, orange-yellow spotted "vvith brown; 

 l^etals pale yellow, also spotted with brown; lip reno-cordate, yellow, having 

 a broad, square, brown blotch at the base, and several small blotches towards 

 the anterior margin. — Mexico (?) 



Fig. — Lindenia, v. t. 218. 



O. MACULATUM INTEGRALE, BM. /.—A very interesting variety of 

 0. maculatum, having the same habit of growth. ' The flowers have the sepals 

 light brown, the petals white with a few transverse bars of brown at the base, 

 and the lip white with a yellow crest. — Guateviala. 



O. MADRENSE, EM. f. — According to the strict rules of nomenclature this 

 species ought, perhaps, to bear the name of 0. maxillare, published by Lindleyin 

 1847, but as there appears to be some doubt as to the present plant being identical 

 with Lindley's species, and as, besides, it is so well known in gardens by the name 

 we here adopt, we have considered it more convenient for garden pvirposes to 

 retain Reichenbach's name and to relegate the Lindleyan designation to the 

 synonymy. It is a very distinct and handsome species, with tall ligulate or 

 narrowly-oblong two-edged pseudobulbs, lorate acute i'^ervose leaves, and lateral 

 scapes bearing an inclined raceme of about eight showy flowers, which are 

 deliriously fragrant, and 3J or 4 inches across in their vertical diameter ; the 

 sepals are lanceolate acuminate, white with a bilobed ireddish-purple blotch at 

 the base, the petals broader oblong, white with a purple blotch twice as long as 

 that of the sepals, and the lip shorter ovate cuspidate, , with a claw which bears 

 two collateral crispy calli, which, with the disk, are bright orange. This species, 

 which blooms during the summer months, and lasts several weeks in perfection, 

 is well grown by W. Vanner, Esq., of Chislehurst. — -Mexico.

O. MAESEREELIANUM.— See 0. luteo-puepureum Maesekeeliaxum. 



O. MARRIOTTIANUM, J?c7i,5./.— Perhaps a natural hybrid imported with a 

 batch of 0. cirrliosum by Mr. Marriott, of Edmonton. In groivth it appears to 

 approach nearest to 0. Rallii. Sepals twisted, petals broader, wavy, both white 

 spotted inside with pale purple, the former having a purple median line at the 

 back; lip pandurate wavy, having some narrow brown stripes at the base. — 

 Ecuador {?)

O. MAXILLARE.— See 0. madeense. 



O. MULUS, Bchh.f. — A very handsome plant, intermediate between 0. luieo- 

 purpureum and 0. glorioskm, differing from the flrst in its narrower sepals and 

 petals and its constricted pandurate lip, and from the second in its broader sepals 

 and petals, its pandurate lip, the thicker cirrhi of its column, and its radiant sub- 

 basilar callus ; the habit and vegetative organs of the plant resemble those of 

 0. luteo-purpureum, and it produces large branching many-flowered panicles of
