worth & Co., and recorded in 1919. The former parent is considered to be 
a fine variety of S. Ruckeri. 
S. mirabilis (macrantha xX Veitchii), was raised by Messrs. Sanders and 
exhibited by them at the Royal Horticultural Society, May 5th, 1903. 
S. roseo-macrantha (rosea X macrantha), was first seen in 1897, when 
the flowers were described as being large, purple-rose, the sepals and petals 
margined with white. It was raised by Messrs. Veitch. 
S. Siebertiana (Hodgkinsonii xX macrantha), appeared in 1908, when it 
was exhibited by Messrs. Sanders. The large mauve-purple flower had a 
white throat. 
S. Veitchii (macrantha X xantholeuca), received a First-class Certificate, 
R.H.S., when exhibited by the raisers, Messrs. Veitch, July 24th, 1894. 
The flower was blush-tinted, the lip flushed with rose-lilac, especially round 
the margin. In 1918 there flowered at Kew a Sobralia, presumably a wild 
plant, that was indistinguishable from S. Veitchii, thus strengthening the 
belief that this latter plant also occurs in the wild state. 
S. Wiganiz appeared in 1892, and is believed to be a natural hybrid 
between macrantha and xantholeuca, consequently a variety of S. Veitchii. 
It bore large soft yellow flowers tinged with rose.

ONCIDIUM ORNITHORHYNCHUM.—This pretty species is a native of 
southern Mexico and Guatemala, where it grows at a considerable 
elevation. It was originally described in 1815, but did not appear in 
British gardens until 1836. The specific name is derived from the Greek 
for bird’s beak, in reference to the beaked anther. The variety album first 
appeared in Mr. John Day’s collection at Tottenham in 1873. The panicled 
scape bears numerous flowers, a little less than an inch across and of rose- 
lilac colour, except in the variety album, when the only colour is seen in the 
yellow crest. This species is of easy cultivation and succeeds well in the 
cool house.

OncipIUM MARSHALLIANUM.—The early summer months see this species 
at its best, for it is then that the much-branched panicles bring forth 
numerous golden-yellow flowers that frequently measure three inches across. 
It was introduced by Messrs. Low & Co. in 1865, through their collector, 
Blunt, along with Oncidium crispum. It is regrettable that no one 
seems able to cultivate this species successfully for more than a few years: 
The newly-imported plants yield magnificent floral results, but during 
subsequent seasons the flowers gradually become less in number and size 
until at last no spike whatever is produced. An experiment might be made 
in raising the species from seed under the usual greenhouse conditions.
