them in bloom. At the present time Sophrocattleya Chamberlainiana, 
Calypso, Nydia, eximia, Sophrolzlia heatonensis, Marriottiana, and Eros 
have their flowers open; others being in full growth their flower buds can 
easily be discerned pushing up in conjunction with the new shoots. They 
thrive best when suspended near to the roof glass on the lightest side of the 
Intermediate house, where the moderate sunlight tends to intensify the 
colour of the flowers. Keep these plants well supplied with water till the 
new growths are made up. 
OncipiuMs.—The useful Brazilian Oncidiums, O. Forbesii, crispum, 
and varicosum are now making roots freely and sending up their flower 
spikes. Strong well-rooted plants May be allowed to carry their full 
complement of bloom, but it is advisable that those plants that produced 
exceptionally strong spikes last year, and small weakly plants, should have 
their flower spikes removed. Every growet who has had any experience 
with this class of Oncidium knows what fine spikes can be easily obtained 
from them within a few months after. being imported, and they also know 
that in many cases, after bearing such spikes and keeping them for a long 
time on the plant, the plants eventually have gradually dwindled away, in 
spite of every care bestowed upon them. Therefore, to keep the plants in 
good health, it is advisable to cut off the spikes soon after the flowers are 
open, and afterwards to give them a good rest, not allowing them to bloom 
again till they have recovered and made good bulbs. OO. concolor will by 
this time have made up its bulbs, and will not need anything like so much 
water as when growing, but it must not be treated quite decidedly as @ 
resting plant. 
ORCHIS LATIFOLIA.—A colony of about twenty plants of this beautiful 
native Orchis, as grown in the Royal Horticultural Society’s garden at 
Wisley, is illustrated in a recent issue of The Garden (p. 438). It is 
remarked : ‘‘ It would be difficult indeed to find a plant more interesting or 
possessing more charm than this, and owing to its preference for damp, 
marshy spots it is essentially a plant for the waterside. . . . The roots 
were planted a little over three years ago in a damp peaty spot with a 
north-west exposure, and the magnificent flower-spikes testify to the 
success of the treatment. The spikes, when the photograph was taken 
early in July, were about eighteen inches high, the bright purple flowers 
creating a welcome bit of colour amid the deep green foliage of surrounding 
vegetation. It has has proved a variable plant under cultivation, but for 
the waterside in semi-wild places the native plant is best. As most 
nurserymen have stocks of this Orchis, there is no difficulty in obtaining 
plants and no excuse for rooting up wild ones for transference to the 
garden.”
