eyes of visitors. The houses have also been divided into four compart- 

 ments, the conditions of which vary in regard to temperature and atmos- 

 pheric moisture. In 1901 a small pit was adapted for the cultivation of 

 Dendrobiums." 



A few changes in nomenclature are alluded to, " the most important 

 being the separation of species formerly included under Cattleya labiata, 

 and the breaking up of the genus Cypripedium." The result of this is that 

 about forty species of Cattleya are enumerated, while the Tropical Asian 

 Cypripediums are transferred to Paphiopedilum, and the Tropical 

 American to Phragmopedilum. The tall, reed-like plants to which the 

 name Selenipedium properly belongs are not in cultivation. 



The collection of Masdevallias is remarkably rich, over eighty species 

 being enumerated, and several hybrids ; while of botanical Orchids 

 generally it may be said that their name is legion.

ORCHIDS FROM WALTON GRANGE. 



A number of most interesting Orchids are sent from the collection of W. 

 Thompson, Esq., Walton Grange, Stone, by Mr. Stevens. There are 

 flowers of ten different seedlings of Odontoglossum Pescatorei, for such 

 they must be called, though they are the result of a supposed cross with 

 O. cirrhosum, which, however, we think must have been ineffective, for we 

 cannot find a trace of cirrhosum influence anywhere. The shape is typical 

 Pescatorei, but there is a considerable variation in size. The colour also 

 varies somewhat, some forms being tinged with rose, chiefly on the sepals, 

 and others quite white, while some have a few purple spots, and others are 

 quite unspotted. Four of them have branched inflorescences, and one bears 

 as many as twenty-two flowers. Mr. Stevens remarks that some of them 

 have been out at least three months. 



Several beautiful Dendrobiums are also sent, these including D. nobile 

 nobilius, D. n. Sanderianum, with smaller very dark flowers, D. n. pulcher- 

 rimum, a large D. n. Heathii, D. n. Ashworthise, a beautiful white form 

 with purple tips to the segments, and the chaste D. n. album, smaller than 

 D- n. virginale. The others are D. X Ainsworthii Leechianum, the fine 

 light rose D. x A.Thompson's var., the natural hybrid D. X Pitcherianum, 

 D - X Backhousei, now believed to have originated from the same cross as 

 D - X Wiganias, from which it can hardly be distinguished, and a very 

 beautiful form of D. X Rubens, obtained by crossing D. X Ainsworthii 

 splendidissimum with D. nobile nobilius. It has very broad rosy segments 

 and a well-shaped lip.
