ROUGH NOTES ON SIX COMMON HILL ORCHIDS. 417 



2. Ccelogyne ochracea. (Plate A.) — An epiphyte which particu- 

 larly affects oak and rhododendron trees, the latter for choice, and 

 one that grows within a very restricted area of elevation at about 

 5,500 feet. The whole plant is smaller and more compact than the 

 last species, its pseudobulbs and leaves are much yellower in colour, 

 and the flowers are smaller and are produced on upright stems instead 

 of on drooping ones. The flowers are very sweet scented at times, 

 the scent resembling that of a carnation. When the flowering is over 

 the bottom of the flower stem itself developes into the new pseudobulb 

 with its two lance-shaped leaves, so that in an old plant the flower- 

 stalk bearing one or more seed vessels is seen to be growing out of the 

 top of the pseudobulb instead of from below as is the case with 

 Ccelogyne cristata. The flowers are creamy-white, with yellow and 

 ochre markings on the lip. 



Season of rest, October to April. Flowering season, throughout 

 May. Season of growth , June to September. 



3, Dendrobium amoenum. (Plate B.) — On trees of all sorts, 

 batween 4,500 and 5,500 feet elevation. The pseudobulbs of this 

 orchid (as of most, if not all, Dendrobiums) are the jointed reed-like 

 stems of the plant itself, which grow to about two feet in length. 

 About April the joints of last year's stems (particularly all the upper 

 ones) will be seen to be swelling, and gradually these swellings will 

 dsvelop into buds, two or three at each joint; and, if the plant be a fine 

 specimen, the splendid show of flowers makes up for the want of leaves, 

 for, unfortunately, this Dendrobium is not evergreen, but drops its leaves 

 annually. Whilst flowering, or just after, the new growth will be 

 observed pushing its way from the base of the flowering stem, and as it 

 grows it throws out small lance-shaped leaves from the joints. The 

 flowers, which measure about two inches across, are white with magenta 

 tips to the petals, sepals and lip, whilst the latter is marked with yellow 

 inside as well. The flowers have a delicious scent of violets. I have 

 never observed this orchid flowering from stems more than one year 

 old, whereas many Dendrobiums go on flowering from old stems for 

 years. 



Season of rest, October to April. Flowering season, during May. 

 Season of growth, June to September. 



Many Dendrobiums are easily propagated by cutting off an old stem 

 and laying it in moss kept thoroughly damp, thus inducing young plants
