FHOM THE i?0CIETV3 GARDEN. 59 



aie compressed bodies, in form not unlike a flat flask, and piled 

 one over the other in the singular manner shown in the annexed 

 cut, which represents the plant of its natural size. The flowers 

 are white, smooth, with a slight tinge of green, but otherwise 

 colourless. The lip is 3-lobed, with 3 elevated parallel lines, 

 the middle lobe the longest, oblong and acute. The fcot of the 

 column is neither chambered nor toothed. 



In all respects this plant is so entirely an Eria tliat it is 

 referred to that genus, notwithstanding that, in the flowers ex- 

 amined, the number of its pollen masses was only 4, instead of 8. 

 But this may have been accidental. In its 3-ridged lip, and 

 reflexed bracts, it so strongly calls to mind that genus, as to 

 raise a reasonable presumption, that the number of pollen masses 

 would, in more perfect flowers, be as usual. 



A hothouse plant of no horticultural interest. 



7. OXCIDIUM PLAXILABRE.* 



Received from R. A. Grey, Esq., who obtained it from 

 Brazil and presented it to the Society through Thomas 

 Edgar, Esq. 



This plant has the foliage of O.Jlexuosum, and flowers much 

 like those of O. Suttoni. The pseudobulbs are thin, sharp 

 edged, and ribbed at the side. The leaves are sword-shaped, 

 lorate, recurved, and shorter than the raceme. Tlie raceme is 

 long and narrow like that of the Sutton Oncid ( O. Suttoni), and 

 the flowers are as nearly as possible of the same colour ; that is 

 to say, the sepals and petals are dull brown tipped with yellow, 

 and the lip is clear yellow stained with cinnamon brown at tlie 

 base. The sepals and petals are nearly of the same size and 

 form, rhomboid-lanceolate, acuminate, wavy, very distinctly 

 stalked. The lip is three-lobed, with the side lobes nearly as 

 wide as that in the centre, which is slightly stalked, nearly 

 hemispherical, emarginate, and perfectly flat. The crest con- 

 sists of a broad lozenge-shaped rugged-edged cuspidate process, 

 beneath which, near the point, on either side, are two small 

 unequal tubercles ; in addition to which there is a stout blunt 

 tooth which rises in front of the column, forming part of it. 

 The wings of the column are roundish, dwarf, and incurved.
