first at Farnham Castle, in 1856, at the Lord Bishop of Win- 
chester’s; immediately afterwards in the Berlin Gardens, all the 
plants having been sent by v. Warpewicz. Then Mr. Linden 
obtained it from Mr. Wallis, most probably from Ecuador. It is 
a very recommendable plant: the one in the Hamburgh Botanic 
Garden remained in flower for a long while. 
Two very remarkable leafy organs stand beneath the pseudobulb ; 
the inferior one a triangular keeled sheath; the superior one a 
sheath with an articulated cuneato-ligulate acute leaf. Pseudobulb 
oblong, narrow before, finally rounded, ancipitous, finally ribbed, 
leek-green; when very weak one-leaved, when strong two- 
leaved. Leaves cuneato-ligulate acute, attaining one foot in length 
and to three inches broad. Inflorescence long, racemose at its 
top, shortly panicled at its base with small one- or two-flowered 
branchlets, all the flowers and branchlets coming from con- 
spicuous marginal-nerved triangular lanceolate sheaths. Bracts 
similar. Sepals unguiculate, oblong-acute. Tepals shorter, 
angular above their base. Lip pandurate, basilar angles retuse ; 
narrow part much constricted; anterior part reniform emarginate ; 
callus rhomboid, with two retrorse shanks, flat at the base, in the 
middle of the anterior with an acute process, on each side of 
which stands a conical small callosity. Column short, thick, with 
adnate wings; rostellum tridentate; a strong tooth before the 
stigmatic hollow ; anther like the beak of a bird. 
Materials :—Description of the living plant in the Saundersian 
garden; inspection of Dr. Lindley's type; sketches and descrip- 
tions of fresh specimens; three herbarium specimens.

Placed in a damp shady temperate stove, this dingy coloured 
Oncidium grows freely and flowers abundantly. When at rest 
it must be but moderately supplied with water. My plants 
came from M. J. Linden, of Brussels, and were labelled from 
Guayaquil. W. W. S.
