THE ORCHID WORLD.

As the fly absorbed the nectar on the anterior 

 part of the hp it gradually approached nearer 

 and nearer the base, seeking for more. As 

 it got to the part of the lip which bends down 

 to join the column the lip began to rise, and 

 as the latter suddenly assumed its normal posi- 

 tion the fly was pressed between it and the 

 column and was for some time held a prisoner. 

 After some struggles it managed to escape, 

 carrying off one of the poUinia glued to its 

 thorax. This incident may assist to throw 

 some light on the use of the mobility of the 

 lip so characteristic of this genus and of 

 Cirrhopetalum."

CCELOGYNE CRISTATA. — At this season of 

 the year plants of Coelo,gyne cristata should 

 be brought into a slightly warmer atmosphere 

 where a minimum night temperature of 50° F. 

 can be maintained, and a position where 

 they can be placed well up to the light should 

 be selected. A cool Cattleya house is very 

 suitable, for if the plants are left in the Odon- 

 toglossum house during the winter the flower 

 spikes are apt to turn black and damp off. If 

 many plants are grown, one or two of the 

 strongest may be placed in a slightly higher 

 temperature ; these will then bloom at an 

 earlier date and the flowering season will be 

 considerably extended. Although considered 

 by many an easy Orchid to grow, it does not 

 always flower the season after the plants have 

 been repotted ; many of the finest spikes of 

 bloom axe produced when the pot is full of 

 bulbs growing in a mass one upon another. 

 The flowering season is February to March, 

 the flowers, some six or eight on a drooping 

 spike, are pure-white, with a prominent 

 blotch of yellow on the crest of the' lip. The 

 varieties citrina and Lemoniana have the 

 centre of the lip stained a delicate I'emon 

 colour ; it is as well to mention that the latter 

 variety, often erroneously spelt with a small 

 initial letter, was named in honour of Sir 

 Charles Lemon. The variety alba, also 

 known as hololeuca, is entirely without the 

 yellow colour, and when first discovered large 

 sums were paid for small pieces ; now it is 

 fairly plentiful, and nice plants can be pur- 

 chased for a few shillings. 



ORCHIDS OF GAZALAND. 



The Journal of the Linnean Society, 

 Vol. XL., is devoted to " A Contribution to
