222 THE ORCHID REVIEW. [JULY, Igrr 
‘This yellow-flowered Cypripedium was originally discovered by Pére 
David in June, 1869, in the pretty state of Moupin, situate in the extreme 
-west of China. It was collected a few years later by Pére Delavay, who 
_records it as being abundant around Tali, Yunnan Province, at an altitude of 
3,000 metres. The present writer first collected it in north-western Hupeh, 
where it isextremely rare. Later, he met with it in greater quantities in various 
localities in the Chino-Thibetan borderland. Its habitat is the margins of 
thin woods and thickets. It also occurs on scrub-clad boulders stranded 
in bogs. Around Sungpan, in the extreme north-west corner of Szechuen 
it is abundant in thin woods of Spruce and Silver Fir, growing near the 
margin of certain glacial torrents, which are surcharged with petrifying 
limestone. Nevertheless, having seen it growing in a variety of soils, one 
would hesitate to say that a calcareous soil is necessary. A cool situation 
and plenty of leaf soil would seem the essentials. This plant, in habit, 
vigour, and general appearance, closely resembles the North-American C. 
spectabile, and where that species thrives C. luteum should succeed.” 
CYPRIPEDIUM TIBETICUM. 
‘Tuis striking Cypripedium was introduced to cultivation six years ago by 
Mr. E. H. Wilson, when collecting in China for Messrs. James Veitch & 
Sons, and its history was given in these pages (O.R., xiii. p. 194). It is 
interesting to learn from the article summarised spe that he has now 
secured an importation of it for the Arnold Arboretum. Very few plants 
were originally introduced, but one of them was figured in the Botanical 
Magazine (t. 8070), and the species received a First-class Certificate from 
the R.H.S. at the Temple Show in May, 1906. Mr. Wilson now remarks: 
“C. tibeticum is widely-spread along the Chino-Thibetan borderland and 
on the Alpine moorlands at an altitude of 3,000-4,000 metres, and is one of 
the commonest plants. It occurs in countless thousands,’”’ as shown in 
a photograph reproduced as a supplementary illustration. ‘It is possibly 
one of the finest of all-red flowered hardy Cypripediums.” The species, 
-afterwards described as C. corrugatum, Spies: is now considered identical. 
ONCIDIUM . ‘CLARSII. 
A PLANT of this striking Oncidium has now flowered in cultivation, in the 
collection of Sir Jeremiah Colman, Bart., Gatton Park, Reigate, and was 
exhibited at the recent Temple Show, receiving an Award of Merit. The 
species was described over four years ago (Kew Bull., 1g06, p. 376), from 
Colombian materials collected by M. Fl. Claes, Etterbeek, Brussels, the 
-collector describing the inflorescence as 12 to 18 feet long, entangled and 
twisted round the branches of a shrub, and bearing numerous large flowers 
‘with chocolate-red sepals, the petals and lip case carmine, Hinged with
