100 THE ORCHID REVIEW. [APRIL, 1969. 
NOVELTIES. 
A THIRTY-THIRD decade of New Orchids is described in the last issue of the 
Kew Bulletin, seven of the species being in cultivation, as follows :— 
OcTOMERIA ARCUATA, Rolfe.—-A Brazilian species, introduced by Messrs. 
Sander & Sons, and flowered at Kew in November, 1908. It is allied to O. 
sarcophylla, Rodr., and has light yellow flowers, with the keels and side 
lobes of the lip, and the column dark red-purple. The leaves become 
purplish on both surfaces on reaching maturity.—Kew Bulletin, 1909, p. 61. 
OBERONIA UMBRATICOLA, Rolfe.—A Siamese species, allied to O. 
pachyrachis, Rchb. f., and having minute buff-orange flowers, arranged in 
a narrow spike. It was collected at Doi Govtep, in very shady jungle, at 
1,500 m. elevation, and flowered at the Trinity College Botanic Garden, 
Dublin, in November, 1908.—l/.c., p. 62. - 
BULBOPHYLLUM (Cirrhopetalum) CAMPANULATUM, Rolfe.—A Sumatran 
species, sent from the Brussels Botanic Garden, and flowered at Kew in 
October, 1908. It is an elegant little plant, and the strongly decurved 
united lateral sepals give the inflorescence a campanulate shape, in allusion 
to which the name is given. The lateral sepals are pale pink, with many 
minute darker dots, and. the other segments are pale whitish yellow, striped 
and fringed with dark purple.—/.c., p. 62. 
POLYSTACHYA STRICTA, Rolfe.—A species from British East Africa, which 
flowered at the Cambridge Botanic Garden in August, 1903. It is allied to 
P. Rive, Schweinf., and has light greenish yellow flowers, with a few faint 
purple streaks on the base and side lobes of the lip.—l.c., p. 63. 
CYCNOCHES DENSIFLORUM, Rolfe.—(See p. 104 of the present issue). 
ORNITHIDIUM BICOLOR, Rolfe.—A Colombian species, allied to O. 
coccineum, but having bright yellow flowers, with a large crimson blotch on 
the front lobe of the lip. It was introduced by Messrs. Linden, of Brussels, 
who flowered it in June, 1gor, and presented it to the Kew collection. It is 
remarkable for producing two kinds of growth, the first an ordinary pseudo- 
bulb, and the second a leafy flowering branch, which produces a succession 
of flowers from the leaf axils, as in O. coccineum.—-l.c., p. 65. 
SOBRALIA VALIDA, Rolfe.—A very distinct species, belonging to a small 
group having an arrested inflorescence, glabrous leaf-sheaths and crested 
veins to the lip, of which only five species were previously known. The 
stems are under a foot high, stout, and the flowers whitish yellow, with a 
deeper yellow band on the lip, becoming orange-coloured in front. A plant 
flowered at Kew in June, 1907, having been received through Messrs. Sander 
& Sons. It had been obtained by Dr. Hodgkinson, Wilmslow, from the 
Darien Gold Mines, Panama, with a few other Orchids.—!.c., p. 65. 
The three other species are ERIA SOLOMONENSIS, Rolfe (p. 63), a Solomon
