in summer. Canvas shading, raised eighteen inches above the glass, is used 
through the heat of the day in summer, but during the winter no shade 
whatever is used. 
The collection contains over one hundred unflowered crosses of the 
concolor section. Many are about to bloom, such as niveum § x Elliot- 
tianum 2, bellatulum 2 x villosum @, bellatulum 2 x insigne maximum @, 
Lawrenceanum Hyeanum ¢ x niveum ¢, and x Marshallianum ? x Lawrence- 
anum g, &c.; with many fine named varieties, such as C. x Tautzianum, x 
Marshallianum and varieties, x Antigone, x Arete, x Aylingii, x tessella- 
tum porphyreum, xX microchilum, x Arnoldianum, x Gravesiz and var. 
superbum, x Georgianum, &c. This last has just flowered, and is a cross 
between C. superbiens 2 xX niveum jf, the scape is double flowered, the 
flowers nearly four inches across, the dorsal sepal short, greenish white with 
brown markings at the base; the petals white suffused with vinous purple 
and specked with crimson ; and the lip rich vinous purple. The name is 
given in compliment to Mr. George Graves. 
A complete list of those at present in flower would consume too much 
space, but of the older varieties may be named Selenipedium Lindleyanum, 
Klotzchianum, and caricinum, and the hybrids S. x leucorrhodum, x 
Schroederze, x Sedeni and var. candidulum, x cardinale, x grande and var. 
atratum, xX Dominianum, and x calurum Rougieri; Cypripedium x 
Harrisianum, x Bartetii, &c.; fine specimens from two to five feet across, 
and each a shower of bloom. Among the choice varieties in flower may be 
mentioned Cypripedium x Aylingii, x Gravesiz, x almum atropurpureum, 
x rubescens pictum, x Beatrice, x Vibilia, x Greyanum, xX Winnianum, 
x orphanum, xX Schlesingerianum superbum, xX Germinyanum, and x 
Godseffianum, also C. Chamberlainianum in variety, &c., &c. 
Among the Vanda group there is little in bloom at present except Vanda 
suavis, tricolor, insignis and varieties, Aérides odoratum, Rohanianum, 
Fieldingii, Savageanum, and Vandarum; together with Angraecum Sanderi- 
anum and sesquipedale. The Vandez are all potted in charcoal, with a 
light top dressing of chopped live sphagnum; and are syringed overhead in 
fine weather. Air is admitted at all times in greater or less quantity accord- 
ing to the weather, and a temperature of 70° by day, and 60° at night 
maintained. 
The adjoining compartment, sixty-five feet long by eleven feet wide, is 
devoted principally to Dendrobiums, of which about fifty species and 
varieties are cultivated, many of the commoner ones in quantities for cutting 
from. At present there are some fine specimens of D. thyrsiflorum, densi- 
florum, superbum, Findlayanum, Dalhousieanum, forty spikes, &c. The 
house is kept at about 50° during winter, and 70° to 75° (as near as possible) 
in summer. With few exceptions the plants are grown in sphagnum, with 
liberal drainage ; syringing taking the place of watering.
