root into the new compost. They can either be potted singly or, if 
specimen pots are required, several in a pot, and when well grown they are 
very effective when dotted about the conservatory. They like a mixture of 
loam, dried cow-manure, and peat, with plenty of drainage, so that they 
can be freely watered in their flowering season. If there is not much room 
for them in the Orchid houses, they will grow well in a Melon or Stove 
house. Care must be taken not to over-water them until they get well 
established, or black spots will soon appear on the young growths. 
TEMPERATURES can be raised 5° to 10° all round now, as the outside 
conditions improve, and air be given on all favourable occasions, if only for 
an hour, so as to change the air in the houses, and prevent them from 
becoming stagnant with the extra moisture required. 
DAMPING can be done several times daily, to keep a nice growing 
atmosphere, especially on a hot day, when the ventilators are open and 
moisture soon escapes. 
SHADING must be carefully watched, as plants soon scald after the dull 
winter months, and a scalded plant is an eyesore for several years. Unfor- 
tunately, Orchids cannot be propagated as quickly as geraniums, and the 
grower is reminded of carelessness every time he sees a scalded leaf.

The second fascicle of this interesting work has just appeared, and 
contains an important paper entitled ‘‘ Studies in the Orchid Flora of the 
Philippines,” in which a large number of new species are described. The 
plates illustrate the following :—Dendrobium acuminatum, Rolfe, 
Bulbophyllum lasioglossum, Rolfe, B. Copelandii, Ames, and eighteen 
species of Dendrochilum, all natives of the Philippines, with the North 
American Spiranthes longilabris, Lindl., and Hormidium tripterum, Cogn., 
a widely-diffused Tropical American species. There is also a short paper 
on “ New Species and Names of American Orchidacez,”’ in which several new 
species of Pleurothallis, two Masdevallias, and a few others are described. 
The work concludes with a complete Index to this and the preceding fascicle. 
ALBINISM IN PAPHIOPEDILUM INSIGNE.—Mr. J. H. Grogan writes :— 
Have we a true albinio ofthis species? I have never seen one. C. insigne 
Sandere has a minute trace of purple in the dorsal sepal, and C. i. 
Sanderianum, though without any perceptible colour in the flower, has a 
decidedly coloured flower-stalk.
