Jury, 1911.) THE ORCHID REVIEW. 205 
-very clean, and tobacco water is used to keep awe thrip whenever 
mecessary. 
A fine lot of etamnoreds have already been mentioned. During the 
summer, from May to September, they are suspended on wires against a 
-south wall, under an immense camphor tree (Cinnamon Camphora), which 
provides the necessary shade. Here they are said to thrive and flower 
profusely, watering as often as necessary being practically the only atten- 
tion they receive. This treatment was the result of experiment, for it was 
found that they did not thrive in the house, being much troubled with 
thrip. The summer is hot, and practically rainless except for a few 
showers. Such treatment is, of course, not practicable in England. We 
saw these plants in their summer quarters, about thirty of them, and very 
‘healthy they looked. They included plants of Stanhopea Wardii, oculata, 
graveolens, tigrina, eburnea, Martiana, Ruckeri, and others. 
The collection has for many years been under the care of M. Lodovico 
Vannini, who may be congratulated on his success, for many of the plants 
have been here since their original introduction, and there are many 
difficulties to encounter in sucha climate. Copious shading is necessary 
during the summer, but the weather is often cold during the winter, owing 
to the proximity of the Apennine Hills. It may be added that the fuel 
cused is a brown lignite, which is obtained in the vicinity. 
Mrs. Ross has a very large collection of paintings, made by herself, the 
majority many years ago, in the lifetime of Mr. Ross, who was one of the 
most enthusiastic Orchidists of the day. It was most interesting to look 
through these, and see some of the rarities and historical plants of the 
collection, which, however, we have not space to enumerate. We shall 
Jong reme mber our visit with pleasure. 
CYPRIPEDIUM SPECIOSUM. 
SomE time ago the distinction between the Japanese Cypripedium called 
4. macranthum and the original Siberian species of that name was pointed 
out, when, following Matsumura, the former was referred to the imperfectly- 
known C. Thunbergii, Blume (0.R., xvi. p. 186). It now forms the subject 
of a paper in the Kew Bulletin (1911, pp- 205-208). As the species had been 
figured for the Botanical Magazine, and there was some doubt as to the 
correctness of the name, application was made to the authorities of the 
Rijks Herbarium, Leiden, for the loan of the original specimen of C, 
Thunbergii, and an examination of all the materials has yielded some 
curious results, which may be briefly summarised. Cypripedium Thunbergii 
was based by Blume upon C. Calceolus, Thunb., which he regarded as 
distinct from the European C.Calceolus, L. Ten years afterwards Miquel, 
without seeing a specimen, reduced C. Thunbergii to C. macranthum, and
