THE ORCHID GENERA 67 



bulbs plump, and the leaves fresh and green. Among 

 the sub-evergreen and deciduous section, the following 

 — D. nobile, D. clavatum, D. calceolus, D. Brymerianum, 

 D. Dalhouseianum, D. Dearei, and D. jimbriatum — also 

 grow well in the ordinary flower-pot. The first-named 

 is probably the most popular and useful, and at the same 

 time the most variable, of all the Dendrobes, hardly two 

 plants bearing flowers exactly alike. Shallow pans with 

 perforations around their sides, through which the air 

 can circulate, and so help to keep the roots healthy, are 

 to be preferred for such dwarf-growing varieties as 

 D. atro-violaceum, D. albo-sanguineum, D. Bensonia, D. 

 capillipes, D. Findleyanum, D. Johnsonia, and Z). Parishii. 

 These pans are also suitable for varieties with pendulous 

 stems, as D. chrysanthum, D. crassinode, D. crepidatum, 

 D. cretaceum, D. Devonianum, D, lituiflorum, D. Pierardii, 

 D. primulinum, D. superbum, and D. Wardianum. Like 

 D. nobile, the beautiful D. phaUnopsis Schroderianum is 

 always highly appreciated, and, as in that species, the 

 flowers are very variable, the colour ranging from deep 

 purple to pure white. As suitable companions to this 

 species, the following may be named : D. bigibbum, D. 

 Go/dei, D. Statterianum, and D. superbiens. These may 

 also be grown in shallow pans, and suspended close up 

 to the roof glass. Such distinct species as D. aggregatum 

 and D. Jenkensii flower profusely when affixed to blocks 

 of dried apple wood from which the bark has been 

 removed, suspended in a light, sunny position. Den- 

 drobiums root very freely in an ordinary mixture of 

 peat and moss ; for young seedlings, dwarf and thin- 

 stemmed varieties, I prefer sphagnum moss only. The 

 best time to repot Dendrobiums is when the new 

 growths are starting, which usually occurs soon after 

 flowering. Of course there are exceptions ; for instance, 

 D. phaUnopsis does not recommence to grow for several 

 months after flowering. As regards watering, a great
