of these plants. In the deciduous section those species and hybrids which 
produce their flowers early in the new year are now rapidly finishing their 
season’s growth. When this is completed, which may be determined by 
the end leaf of each pseudobulb being fully developed, they must be placed 
in a drier atmosphere, and receive water at the roots in much less quantities, 
and only sufficient given them to keep them from shrivelling. An excess of 
moisture at the roots of these plants is as detrimental as a parched over- 
dry one. Any plants that are still actively growing should have liberal 
treatment, and be induced to reach the resting stage, so that they may also 
be treated as advised. Plants of D. Phalznopsis that are pushing up their 
flower spikes may have water afforded them whenever they become dry, but 
when their spikes are removed much less will suffice. In those districts 
where fogs prevail in.the autumn it will be advisable to push the plants 
into bloom as early as possible, thus avoiding the pernicious effects upon 
their beautiful flowers. D. formosum is also pushing up its flower spikes, 
and requires similar treatment to D. Phalenopsis. Both require all the 
light possible at this season. The evergreen section, such as D. thyrsiflorum, 
densiflorum, Farmeri, &c., as they complete their season’s growth, should 
receive similar treatment to that afforded the deciduous species. 
CaTTLEYAs, L&LIAS, AND THEIR HYBRIDS.—During the present month 
such plants as C. Warscewiczii, Warneri, Hardyana, and others that have 
passed the flowering stage, will commence to push roots from the base of 
their pseudobulbs, and any that are in need of new rooting material may 
have attention. Lzlia tenebrosa, L. purpurata, Lzliocattleya elegans, 
and their numerous varieties and hybrids will now cammence to grow 
vigorously, and may receive similar treatment, if necessary. Any Cattleyas 
that are producing new roots may be repotted’at this season, but care 
should be taken that only sufficient water is applied to the new compost to 
prevent the plant from shrivelling. The new roots will soon enter the new 
compost and re-establish themselves, if kept on the dry side. Those 
Cattleyas which flower in the autumn, such as C. labiata, C. Bowringiana, 
and many hybrids will have finished their season’s growths and be pushing 
up flower spikes, and these should only have sufficient water to keep them 
plump and healthy, as, if they get water in excess, it will start them into 
growth again, and their flowers will be puny or may turn black and fall off. 
An excess of water at this season may mean the loss of a valuable plant, but, 
still, the other extreme must be avoided. 
Cuysis.—C. aurea, bractescens, Limminghei, levis, and the hybrids C. 
Chelsonii and Sedenii should be suspended at the warm end of the Cattleya 
house, or any similar position, so as to enable them to finish their growths 
quickly, and until these are completed, and the leaves commence to change 
colour, the plants will require water at the roots whenever they appear dry.
