122 ORCHIDS I HOW TO GROW THEM SUCCESSFULLY. 



however, is so very free growing that as soon as the new pseudobulb is 

 formed other growths are pushed from the base, sometimes even before 

 the new bulb has finished its growth, but this is of little consequence. 

 Supposing the principal or first growths are completed by September, 

 the plant should at once be removed to a cooler house where it could 

 have plenty of sunshine and air to mature the growth, but when the 

 first growths come to maturity earlier, the plant may still remain in the 

 Warm house to assist the second growths, but not later than September 

 or October. The removal to a cooler house means the coldest end of 

 the Intermediate house, or even a greenhouse, where the temperature 

 does not fall much ]ower than 45 degrees in winter, gradually with- 

 holding water giving only just sufficient to prevent shrivelling ; and 

 when showing flower the plants should be removed in January into a 

 little more warmth. The plants then would bloom about April, but if 

 wanted in flower a little earlier they should be removed to the warmest 

 house, but avoiding a sudden change from cold to heat, increasing the 

 water gradually, for if given too freely immediately after the plants 

 have come from their resting quarters, buds which should become open 

 flowers sometimes turn into growths. When such flower buds turn to 

 growths they may be taken off when rooting with a heel of the old 

 pseudobulb, and propagated, allowing only those to remain that come 

 from the base. The flowers appear from the sides of the bulbs formed 

 in previous years. This is always a cheap Orchid at from Is. 6d. to 2s. 

 per strong leading bulb, and may also be bought newly imported, as 

 they generally make strong healthy plants. The varieties of D. nobile 

 are numerous and vary in size and colour, the most distinct being 

 D. nobile album, and the best dark form D. nobile nobilius. 



DENDROBIUM x AHSTSWORTHII. Garden Hybrid. 



This is a very pretty and useful hybrid, the result of a cross 

 between D. nobile and D. aureuni, and more adapted to basket than 

 pot culture, but with the same treatment as that of D. nobile. 



This also is a cheap Orchid and obtainable at from 5s. per strong 

 flowering- sized leading growth. 



DENDROBIUM AUREUM. From the East Indies. 



This species is of a golden yellow colour and deliciously scented, 

 and does best in baskets, but with the treatment given to D. nobile, and 

 it also blooms from the preceding year's pseudobulbs. 



Good established plants should be purchased for about 5s. per 

 strong leading bulb, and newly imported plants at a cheaper rate, as 

 they grow very freely. Let 50 degrees be the minimum during winter. 



DENDROBIUM FINDLAYANUM. From Burmah. 

 Although different in habit to the preceding it is a very pretty 

 species, flowering in the late winter or early spring months, the flowers
