114 THE ORCHID REVIEW. [APRIL, 1923. 
pseudo-bulbs that have been taken from the plants, may be utilised for the 
purpose of increasing the stock if desired. They should be labelled and 
placed in a warm house for a week or two to dry. They may then be cut 
up to a single eye that has not produced a flower bud, leave rather more of 
the stem at the bottom to insert in the compost, in order to keep the cutting 
in an upright position, without covering the dormant eye. Use four-inch pots, 
half filled with clean crocks, and fill up to the rim with chopped sphagnum- 
moss and silver sand. When the young shoots are about an inch in length 
they should be potted up singly in small pots. Dendrobiums should be 
grown in the warmest house, with an abundance of light at all times, 
affording only sufficient shade to prevent the leaves from scorching. 
MAXILLARIAS.—Certain species of Maxillaria, including the well-known 
M. venusta, M. candida, M. Mooreana, and M. picta are becoming active at 
the roots, and plants that require fresh rooting materials should be given 
attention. Those mentioned are best grown in pots or pans, which should 
be well drained. When potting, press the compost firmly around the base 
of the plants. After repotting, they should be placed in a shady position 
in the house, and watered carefully, the water should be poured around the 
inner edges of the pots so that it may not lodge in the young growths. 
Such species as M. Sanderiana and M. Lindenii, that flower at this season 
of the year, are best grown in teak-wood baskets, as the flower-spikes some- 
times push downward through the bottom of the receptacle ; for this reason 
crocks should not be employed for drainage. These two species, together 
with M. Hubschii, should not be potted until after they have passed out of 
flower. Osmunda fibre and sphagnum-moss form the best rooting medium, 
and the plants grow well in the coolest part of the intermediate or the 
warmest end of the Odontoglossum house. 
OponToGLossuMs.—Plants of Odontoglossums that have failed to pro- 
duce flower-spikes, or that have recently passed out of flower, and in which 
the young shoots have grown two or three inches in height, may be repotted. 
But those with sufficient rooting space, and compost that has not decayed, 
are best left until the autumn. Other plants that have outgrown their pots, 
and have the leading shoots over the edge, should be turned out and some 
of the back pseudo-bulbs removed ; the plants may then be potted up again 
in receptacles of a similar size. Those plants that have recently had their 
flower scapes removed, and have not yet commenced to grow afresh, should 
be induced to take a short rest, and only given sufficient water at the roots 
to prevent the bulbs from shrivelling.
