THE MOST USEFUL ORCHIDS 63 



Wallisii, smaller and paler than the type ; and C. c. Warsciwiczii, 

 with shorter, darker foliage, and rosy-flushed flowers. 



C. Charlesworthii, a dwarf Burmese species, will thrive 

 under the conditions that prove suitable for C. insigne and its 

 varieties. Few Orchids have created so great a sensation as 

 C. Charlesw^orthii ; in 1903 it first flowered in this country, and 

 when exhibited by Messrs Charlesworth, Shuttleworth & Co., of 

 Heaton, Bradford, its large, flat, deep rose-coloured dorsal sepal at 

 once attracted attention and suggested great possibilities to the 

 hybridists. For a little while it was a rare plant, but other 

 importations were received, notably by Messrs Hugh Low & Co., 

 and plants were sold at public auction during the following year, 

 so that within twelve months of the time the species first came 

 before the public it was to be found in nearly all the leading 

 Orchid collections in the land. The discoverer was Mr R. 

 Moore, who found it in the Shan States, twenty-five miles south- 

 west of Lake Inle, at an elevation of 5000 feet above sea level, 

 and on limestone hills. It was subsequently found at places scores 

 of miles from the spot where Mr Moore discovered it. The petals 

 and lip of C. Charlesworthii are yellow-green, heavily shaded 

 with brown, and the broad dorsal sepal shows considerable varia- 

 tion. This may be deep rose or it may be pure white, though 

 the latter is rare. Sometimes the sepal appears to be white, suffused 

 and veined with rose. It is a charming little Orchid, rarely more 

 than nine inches high. Grown under the very coolest conditions 

 that will suffice for C. 'ms'igne it grows slowly, but if given the 

 temperature of a warm greenhouse, i.e. a minimum of 50 degrees, 

 it grows better and flowers freely. 



C. CuRTisii was discovered by the writer's relative and name- 

 sake, in Sumatra, when collecting for Messrs Jas. Veitch & 

 Sons, Chelsea, in 1882. The large bold flowers are produced in
