Still later Franchet and Savatier called it C. macranthum var. ventricosum,.. 
citing two Japanese figures, but giving no character. Pfitzer again separated 
C. Thunbergii, including C. macranthum, Franch. and Sav.,as synonymous, 
while Matsumura followed suit, adding also C. Calceolus var. Atsumori as a 
synonym. The last-named is evidently C. Atsmorei, Morren, described and 
figured in 1851, from a specimen which flowered at the Ghent Botanic 
Garden, and which is said to have been received from Siebold among a 
number of other living plants from Japan. C. Thunbergii-is only certainly 
known from Blume’s original specimen and figure, and in the latter the 
details of the lip are incorrectly drawn, and are so repeated by Pfitzer. It 
is suggested that Honzo Zufu, xxxix. t. 19, one of the figures cited by 
Franchet and Savatier, may belong here, and it is hoped that this note may 
lead to the re-discovery of the lost species. The remaining Japanese- 
specimens and figures belong to the other species, and as it is without a 
name that of C. speciosum, Rolfe, is proposed. It is described as a commom 
Japanese plant, hitherto confused with the preceding and with the Siberiam 
C. macranthum, Swartz, but differing in the colour of the flowers, which are 
white or pink veined with rose, and in some small details of floral structure 
According to Matsumura, it grows as far north as Urup, in the Kurile 
Islands. It will be fully characterised in the Botanical Magazine, t. 8386.

CooL. House. 
As we are now, or should be, experiencing summer weather, every effort 
must be made to keep this house as cool as possible, and it should be- 
exceedingly damp throughout this month. Syringe the plants overhead 
about nine in the morning, two o’clock in the afternoon (providing that the- 
house is well shaded), and again at six in the evening. Damping the paths,. 
staging, and walls should be done four or five times daily. All plants must 
now be examined every morning, and if inclined to be at all dry, should 
receive a liberal supply of water. This, however, does not apply to those 
at rest, nor to any which have been freshly potted. If the Orchids are kept 
well watered, and abundance of air be given during the day, as well as some 
at night, the plants will keep clean and healthy. No fire heat will now be 
needed for this house, but the temperature must not descend below 
58° Fahr. Shading will be needed from 9.30 a.m. till the sun is well off 
the house, heavy shading and an abundance of moisture combined with 
plenty of air, will alone. prevent the temperatures from rising too high. 
This month is not one when very many Cool house Orchids are in flower,. 
‘but Odontoglossum hybrids and. Oncidium Marshallianum should still heep 
the house gay.
