THE ORCHID REVIEW. 279* 



its flower spikes in most collections, and at the same time rooting freely. 

 The plants should be suspended near the glass in the warmest house, and 

 should be given plenty of moisture at the roots, and in the atmosphere, 

 until out of flower, when only sufficient will be required to keep the foliage 

 healthy during the winter months. 



In the East Indian House plants such as Saccolabiums, Aerides, Angrae- 

 cums, &c, will have almost completed growth, and will need slightly less 

 water, both atmospherically and at the root, than hitherto. Ventilate as 

 freely as conditions will allow, and afford them plenty of light, in order to 

 consolidate the new foliage, preventing at a later period any attacks of 

 fungoid spots, which soon disfigure the appearance of this class of Orchid. 



The long-bulbed section of Cattleyas, such as C. granulosa and its varieties, 

 prove very useful at the present time. Their culture is not at all difficult, 

 being quite identical with that the other inmates of the Cattleya house. 

 When out of flower these should be allowed to gradually lapse into a resting 

 condition, taking care not to withhold water from the roots too quickly, for 

 they will continue to make new roots freely from the base of the newly- 

 made pseudobulbs. 



The deciduous Dendrobiums, as soon as the growths have reached 

 maturity, should be removed to a cooler, more airy posi ion, and gradually 

 brought to a condition of rest ; any that are backward being given a good 

 position at the warmest end of the house, so that they may reach maturity 

 ere the winter sets in. The evergreen Dendrobiums may now have the 

 benefit of strong sunlight, with ample ventilation, whenever these are 

 procurable, giving water in sufficient quantity to maintain the pseudobulbs 

 in a satisfactory condition. 



Thunias have now mostly ripened their growths, and, where the foliage 

 has dropped, should be placed in a cool, dry place and given a long rest, 

 thus ensuring the appearance of strong breaks in the spring. 



Disa grandiflora.— I find the most suitable time for potting this 

 lovely Orchid is the latter end of September or beginning of October, for 

 the fleshy roots have not got so far advanced in growth as to be injured by 

 this process. Having had a good rest after flowering, this operation may 

 be commenced wherever necessary. I prefer perfectly clean pots and 

 crocks, this being very important, for the roots of Disas will not enter 

 anything dirty or sour. In crocking, which should be done carefully, the 

 crocks should be on their ends, so that the roots may ramble down 

 between them without turning in a horizontal direction, as they will do if 

 laid flatways. On top of the crocks place a layer of moss to prevent soil 

 from choking the drainage. The potting compost should consist of three 

 parts spongy peat, with bracken roots in it, a little turfy loam, with a 

 small quantity of cow manure, thoroughly dried before using, mixing
