622 orchid-grower's maniul. 



leaves, and scapes several feet long, twining, brancKing, and many-flowered. 

 The flowers are from 3 to 4 inches across, the clawed sepals and petals orbicular 

 oblong broad thick and fleshy, the upper one of a golden olive-brown, the two 

 lateral sepals deep orange-yellow, and the two petals of a clear bright yellow ; 

 the lip is hastate, much smaller than the petals, white, the side lobes dark 

 purplish-brown. It is one of the finest species yet introduced, and blooms 

 during spring and early summer, lasting long in full beauty. The cool house 

 suits it best, and it should be potted in peat and sphagnum moss, with good 

 -drainage. — New Grenada.

O. MACRANTHUM WILLIAWISIANUM, iJc7i6./.— A most distinct and curious 

 variety, having on each petal a large blotch of Indian purple, a style of marking 

 which makes it a striking contrast to the original or typical form. It flowers 

 during the summer months. — New Grenada. 



O. MACROPETALUM— See 0. micbopogon. 



O. MACULATUM, Lindl. — A neat and pleasing species, with ovate compressed 

 angulate pseudobulbs, bearing two broadly ligulate leaves at the top, and having 

 others springing from the base, out of whose axils the scape arises. The flowers 

 are in racemes, and consist of obovate-lanceolate acuminate yellowish-green 

 sepals and petals marked with purple blotches, and an oblong-ovate apiculate lip, 

 which has a stout tooth on each side about the middle, and is of a pale sulphur- 

 yellow, whitish at the base, where there are also four simple cuspidate keels. 

 It is a plant of free and compact growth, producing its flowers during the 

 winter and spring months. — Mexico.

O. MANTINII, Godefroy. — It has been suggested that this is another natural 

 hybrid, and that either 0. MaraJialUanum and 0. Gardneri or 0. sarcodes are the 

 probable parents. It was imported with a batch of 0. criepum by Mr. Binot and 

 flowered with Mr. TrufEaut of Versailles. In growth it resembles 0. Qardneri. 

 The dorsal sepal small, incurved at the tip, chestmit-brown with a narrow yellow 

 margin ; petals much larger, measuring 1^ inch in length and 1| inch in breadth, 

 chestnut-brown with a bright yellow marginal border, having at the sides a few 

 red spots ; ,lip with a narrow isthmus, the middle lobe broadly reniform, four-fld, 

 2 inches wide, clear yellow spotted with bright chestnut. Dedicated to M. 

 Georges Mantin, of Bel Air, a distinguished French Orchid amateur. — Brazil.

O. MARSHALLIANUM, BcJib. f. — This superb species is certainly one of the 

 most noble and brilliant of Onoids belonging to the group which has large-sized 

 petals. The pseudobulbs are terete, ovoid-cylindrical, 2 to 4 inches long, with a 

 pair of coriaceous oblong-lanceolate acute leaves 6 or 7 inches long and 2 inches
