i22 THE ORCHID REVIEW. 



Dendrobiums now developing their flower buds, such as D. thyrsiflorum, 

 D. densiflorum, D. fimbriatum, D. Dalhousianum, D. Farroeri, D. crepi- 

 datum, and D. crystallinum, may be removed from their resting quarters 

 to more warm and humid conditions. Any re-potting necessary should be 

 delayed until after the plants have flowered. 



Cymbidium— Undoubtedly the best species of the genus is C. eburn- 

 eum, which has just passed out of flower. It thrives well if given an inter- 

 mediate temperature, and a liberal amount of moisture at the roots whilst 

 making new growth. This is now commencing, and, should any re-potting 

 be necessary, this should now be done. A suitable compost consists of two- 

 thirds turfy peat, one-third fibrous loam, intermixed with sharp sand, finely 

 broken crocks, or charcoal. Give plenty of drainage for this species, and pot 

 moderately firm, well working the compost down to the roots. Water 

 sparingly at first, keeping the surface and foliage well moistened to 

 prevent loss of foliage, and encourage new growth. C. Mastersii, C. 

 tigrinum, and others in the same condition of growth, may also be repotted, 

 and require less drainage than advised for C. eburneum. C. Lowianum 

 grows best under cooler conditions ; its flower spikes will now be in a forward 

 stage. When these have lengthened, and the buds developed, they should 

 be secured to sticks, to prevent the racemes from being weighed down. 

 They will last in bloom for a very long time if kept in a cool house, though 

 it is advisable to remove the spikes after a reasonable time, in order that the 

 plants may not be too much exhausted. Should any plant not show signs 

 of flowering, any renovation of compost can now be done, but repotting 

 ought to be delayed until such time as new roots appear, later in the year. 

 The remarks as to potting compost will apply likewise to C. Lowianum. 



Coelogyne cristata and its varieties may now be repotted, or other- 

 wise renovated, as their requirements need, using for compost two parts 

 turfy peat to one of sphagnum moss. Sometimes repotting has to be done, 

 when this is the case, remove all the old back pseudobulbs, which will not 

 be required, only potting the younger portions of the plant, taking care to 

 work the compost firmly in the pans, and round the base of the pseudo- 

 bulbs. Those not in need of repotting should have any new growths pegged 

 down that have a tendency to grow over the rim of the pans, and new 

 material added where necessary. Give abundance of moisture overhead, 

 and at the roots, whilst making new growth. C. Massangeana, C. Dayana 

 C. tomentosa, C. speciosa, and others starting new growth, may also be 

 repotted, using compost as advised, with an addition of finely broken 

 crocks and sharp sand. 



Odontoglossum grande will be commencing to form new roots and 

 growths, and may now have attention. I find leaf soil answers splendidly 

 for potting compost, surfacing over with sphagnum moss. Water carefully
