266 THE ORCHID REVIEW. 
include the Maxillarias in their collections. The flowers equal those of li 
venusta, Lindl., and are very similar in shape and size, but quite different 
in colour, being closely striped with red on a light ground, that of th 
sepals and petals yellow and of the lip white. It is a native of Peru, ani 
was introduced to cultivation by Messrs. Linden, L’Horticulture Inte 
nationale, Brussels, some time ago, and has now flowered for the first time 
in Europe. The sepals measure two and a half inches long in the drie! 
‘state, from which the size of the flowers will be readily apparent. Further 
particulars are set forth in the subjoined technical description :— 
Pseudobulbs oblong, subcompressed, 24-3 inches long. Leaves recurved, linear-oblong 
13-14 inches long, 13-2} inches broad. Scapes much shorter than the leaves. Dorsi 
sepal linear-oblong, acute, 2} inches long, 5 lines long ; lateral ones broader at the bas, 
more acuminate above, and somewhat falcate. Petals 2 inches long, 33 lines broad, other 
wise like lateral sepals. Lip 19 lines long, narrowed below, broader above, apex recurvel 
broadly ovate-triangular, undulate; crest oblong, fleshy, with rounded apex. Colum 
clavate, inch long. Sepals and petals yellow, closely striped with red, except near ape; 
lip white, striped with red nearly to apex. 
ONcIDIUM UNICOLOR, Rolfe.—This is a very elegant species, belongins 
to Lindley’s section Tetrapetala barbata, which is characterised by 
lateral sepals being united at the base, and the isthmus of the lip dentici | 
late or fimbriate. It is allied to Oncidium uniflorum, Lindl., 0. longi 
Lindl., and O. Croesus, Rchb. f., but differs from all of them in its mi 
robust habit, and larger flowers, which are of a deep canary-yellow, W8 
out any trace of spots; in allusion to which the name is given. It a | 
native of Brazil, and was introduced by Mr. William Bull, of Chelsea, w 
whom it flowered in September, 1889, and on subsequent occasions: 
raceme is few-flowered, two- to four-flowered in the specimens See? ® 
a little longer than the leaves. It is very distinct in appearance from 
Oncidiums, by reason of its long lateral sepals and unicolorous flow e} 
altogether is a bright and attractive little plant :— i 
& 
Pseudobulbs oblong or ovoid-oblong, subcompressed, 14-2 inches long. Lee 
oblong, subobtuse, 3-5 inches long, 8 lines broad, light glaucous green. Scape O 
inches long, 2-4-flowered. Bracts lanceolate-oblong, acute, 4-5 lines long. Pedicels " a 
inches long. Dorsal sepal unguiculate, cuneate-spathulate, subacute, 8-9 nee 
broad ; lateral ones similar, but 13-14 lines long, and united for 4-5 lines at a 
broadly pandurate, 8-9 lines long ; side lobes 2 lines long, 14 lines broad ; front 
ong, § lines broad ; isthmus 2 lines long, much broader near base, mare 
crest consisting of several blunt papilla, in front of which extend three crenulaté ge 
ee ere ones longer than the central one, and with a deep sinus in the m! 
24 lin. long, wings very short, rounded and crenulate. 
PLEUROTHALLIS PUBERULA, Rolfe.—A species which flowered 
Glasnevin Botanic Gardens, under the care of Mr. F. W. Moore é: , 
last. It is allied to P. univaginata, Lindl. of the section Spatna
