completed early in the season, to allow plenty of time for exposing them to 
full sunshine in late summer and early autumn, in order to fully ripen and 
consolidate the newly-made bulbs. 
DENDROBIUMS.—-The different species of Dendrobium, and_ their 
numerous distinct hybrids, have, in some collections, formed a prominent 
feature during the past two months, but the majority are now going out of 
bloom and developing their new growths freely. As the plants quickly 
emit new roots when the growths are a few inches high, those that need 
repotting should at once be attended to. When repotting well-established 
plants, root disturbance should be avoided as much as possible. Plants 
that have filled their pots with roots may be difficult to turn out without 
causing injury, and in such cases break the old pot, and if the soil is 
decayed, pick out as much of it as is practicable, but if it is in good 
condition do not disturb it, merely placing the plant into a larger-sized pot. 
Plants which are unhealthy and have deteriorated from any cause should be 
turned out of the pots, have all decayed roots cut away, and placed in pots 
as small as possible. Dendrobiums root freely in chopped osmunda fibre, 
but only an inch or two of the compost is necessary. , 
For the next few weeks after repotting keep the plants rather on the dry 
side, but as soon as the new breaks send forth roots water more frequently. 
Such strong-growing varieties as D. nobile, Ainsworthii, A. splendidissimum, 
Artemis, Lady Colman, Dominianum, Apollo, Othello, Melpomene, 
Wiganiz, chessingtonense, the various D. melanodiscus hybrids, &c., do 
thoroughly well in pots, provided they have a well-drained open Compost to 
root in, but those with pendulous stems, as D. primulinum, cretaceum, 
crepidatum, lituiflorum, Wardianum, crassinode, superbum, &c., may 
be placed in shallow hanging pans. These pans are preferable to teak- 
wood baskets, because the plants are more readily attended to when they 
need a larger receptacle. These Dendrobes should be grown in the 
warmest house, with an abundance of light at all times. It may not be 
generally known, but many of these Dendrobes, especially those ‘of the D. 
nobile type, will grow, rest, and bloom quite as profusely in a'Vinery as 
they will under special treatment in the East Indian division. 
Ca@LOGYNE CRISTATA.—This useful species has always been a general 
favourite, owing principally to its vigorous constitution and easy culture, 
thriving well in almost any house where an intermediate temperature is 
maintained. Now is the best time to repot any overgrown specimens, or 
to break up those that may have got into an unhealthy condition, remaking 
sired. Unless repotting is absolutely 
but rather, if in gdod health, 
ng those that require it, use 
them up into smaller plants as de 
necessary, do not disturb them in any way, 
allow them to remain as they are. In repottl
