GALEANDRA Devoniana. Schomb. in Lindl. Sert. Orchid. tab. 31. 
One of the finest and, we believe, in collections the rarest of 
South American Orchidez. It was first detected by Schomburgk 
on the Rio Negro, a river which discharges itself into the 
Amazon; and Mr. Spruce has been so fortunate as to meet with 
it in the same locality, and we received a Wardian case from 
him in July, of the present year 1851, containing the flower- 
ing specimen in excellent condition, which we here represent. 
Schomburgk saw it growing five to six feet high, and in clusters 
or patches from ten to twelve feet in circumference. 
Descr. Sfems uniform to the base (no pseudo-bulbs), clus- 
tered, three to five or six feet high, scaly below, leafy above: 
leaves much sheathing at the base, linear-ensiform, acuminated, 
striated, glabrous, membranaceous. Panicle terminal, with few 
but large flowers; branches and peduncles bracteated. Sepals 
and petals spreading and slightly ascending, lanceolate, striated, 
darkish-purple, green at the margin and at the base externally. 
Lip very large, projecting, white, tipped and streaked with 
purple, broadly obovate, obscurely three-lobed, the sides meeting 
so as to form a lax tube around the column, intermediate or 
OCTOBER Ist, 1851.
