P. Coulteri. Dr. Lindley is of opinion that P. macrocarpa Arb. JBrit. and 

 P. Coulteri Arb. Brit, are diiferent plants, and that the true P. Coulten 

 " seems to be still a desideratum in our gardens."

2540. ONCI'DIUM [3807. 



pachyphyllum Hook, thick-leaved £ El or 2 j Y.a Mexico 1839. O p.r.w Bot. mag. 



This species " is remarkable for its large, thick, and very coriaceous leaf, 

 and its ample panicle loaded with blossoms of a greenish yellow colour, spotted 

 with orange and red purple, and not destitute of fragrance." It is also re- 

 markable for having no evident stem, and no pseudo-bulb. It flowers in Ja- 

 nuary. (^Bot. Mag., July.) Dr. Lindley states that this Oncidium is the same 

 as O. CavendishJawm?2 Bate. ; see Hort. Brit., p. 652. 



O. pallidum Lindl. A Brazilian plant, with sea-green leaves, and a panicle 

 almost a foot long ; " very near O. Harrisonianum." {B. M. R., No. 1 08., 



O. Hiinl\hx\\im. Hook, (see p. S-i^.) Dr. Lindley states to be the same as his 

 O. sanguineum : see Vol. XV. p. 398. ; and Sert. Orchid., t. 27. (B. M. R., No. 

 137., September.) 



O. i-amosum Lindl. A Brazilian species, with pale flowers in a large branched 

 panicle, on a scape 5 ft. high. {B. M. R., No. 154., Sept.) 



2562. BRASAVOXvi ' [39. 



venbsa Lindl. veiny-lipped ^ El or 1 o W.c.y Honduras 1839. D p.r.w Bot, reg. 1840. 



This very fine species has the lip white and strongly veined, with the sepals 

 green. " The flowers are deliciously sweet at night." It was imported 

 from Honduras by Messrs. Loddiges, and is nearly alHed to B. nodosa, (see 

 p. 203.) " The leaf is intermediate between that of B. glauca, and the com- 

 mon terete species." {Bot. Reg., July.) 



glatica Bate, glaucous ^ El or 1 W.g.y Mexico 1837. D p.r.w Bot. reg. 1840, 44. 



A splendid plant with a white and green flower, stained with yellow, greatly 

 resembling that of a cattleya. The flowers are very large, and the plant is 

 generally found on oaks (see p. 345.). The species is rather difficult to 

 cultivate, so as to make it flower ; but Mr. Fortune has found that, by de- 

 stroying or keeping back the leaf bud that forms at the base of every flower 

 bud, the latter may be induced to expand. The leaves of this species are 

 large and broad, and very luxuriant. (^Bot. Reg., August.) 



2532. ZYGOPE'TALUM 



africanum' Hoo*. African ^ E] or 1 d Va Sierra Leone 1839. D p.r.w Bot. mag. 3812. 



This plant. Sir W. J. Hooker states, was " sent by Dr. Whitfield from 

 Sierra Leone to the Woburn collection ; " but Dr. Lindley asserts that the 

 plant " is certainly American, and, in all appearance, is a pale variety of 

 Odontoglossum bictoniense, the Cyrtochilum bictoniense of Mr. Bateman's 

 work." (Bot. Mag., July ; and B. M. R., No. 139., September.) 



3603. MYA'NTHUS spinbsus Hook. (See p. 344.) 

 Synonyme : Catasetum spinbsum Lindl. 



This plant, Dr. Lindley states, is a Catasetum. (B. M. R., No. 136., Sept.) 



3597. MONACHA'NTHUS rbseo-albus Hook. (See p. 296.) 

 Synonyme : Catasdtum r6seo-&.lbum Lindl. 



Dr. Lindley observes of this species : " As the genus Monachanthus is 

 suppressed, I am obliged to alter the designation under which the plant has 

 appeared in the Bot. Mag." (B. M. R., No. 135., September.) 



longif51ius Hook, long-leaved jg E] or 1 Y.r Mexico 1839. D p.r.w Bot. Mag. 3819.
