THE ORCHID REVIEW. 121 
Warm house the whole year, is rooting freely, and may have new material, 
and if any require a new basket, the operation should be performed at once. 
They should be suspended near the glass, where they may obtain the 
maximum of heat and light, and given water copiously when growing freely, 
but a very limited supply when at rest. The same remarks apply to C. 
superba. , 
To attempt a detailed account of the treatment required by each 
member of the genus Dendrobium would entail the repetition and 
recapitulation of sentences, which would convey to the general reader the 
idea that a generalising of facts would have served the purpose better; but 
this is not the case, as there are essential details connected with the 
successful cultivation of almost each species, which, when set forth in 
general terms, fail to give an accurate idea of what should be practised 
therewith; hence not to treat each separately would be an unjustice to 
them and myself, and to do so would take up more time or space than I 
have at my disposal, so we must content ourselves by generalising where we 
can, and just mention a few that stand out from the many. Repotting in 
connection with this genus, to do it successfully, is quite a work of art, the 
numerous wire-like roots interlacing themselves and clasping the receptacle 
to such an extent that to dream of removing the plant bodily would be the 
height of folly. When growing in pots or pans, these may be broken 
carefully, and as much ot the decayed material removed as possible, and 
place the broken pieces of pot into another receptacle, always bearing in 
mind that Dendrobes do not like much moisture-holding material about 
their roots. The greater the quantity of material, the greater care will be 
necessarily needed to keep them from retaining a surplus of moisture at the 
root. With a small quantity and this principally peat fibre, with ample and 
effective drainage, water can be given more frequently with less liability to 
doharm. To prevent the accumulation of material use receptacles as small 
as possible. 
The “nobile” section, which for all practical purposes may include, 
besides the type, such as Wardianum, crassinode, primulinum, aureum, 
crystallinum, crepidatum, cretaceum, &c., ; the thyrsiflorum group, such as 
densiflorum, thyrsiflorum, Farmeri, fimbriatum, Dalhousieanum, &e., all 
want strong heat, plenty of atmospheric moisture, and abundance of light 
whilst making their growth, as also do most of the others. D. Maccarthie 
is now showing for bloom;. this species should be grown in shallow pans 
hanging from the roof, giving ample drainage, with a very small portion of 
the best fibrous peat obtainable, moss being a superfluity. Whilst growing 
and rooting freely, too much water can hardly be given it, but when the 
thin stem-like bulbs are completed, only sufficient to prevent shrivelling will 
be needed. The old, but only recently introduced D. veratrifolium is a
