AND THEIR MANAGEMENT. 115 



Girrhopetalum, 



a liberal suppl)- of water during the summer months, and, 

 even during winter, nothing like drying-off" should be 

 attempted, although, as a matter of course, much less 

 water will be required. If shaded from the sun's rays, the 

 flowers ma\- be enjoyed for a long time. The)- all require 

 stove treatment when growing, and a lower temperature 

 whilst at rest and when in flower. 



C. Cumingii {LindL). — A somewhat slender-growing species, 

 having small, four-angled pseudo-bulbs, oblong, blunt leaves, and 

 large, regular, circular umbels of rich reddish-purple flowers in 

 great profusion, elevated on thin, wiry stalks. The lateral sepals 

 give a very peculiar appearance to the flower; they are lin. 

 long, linear-oblong, acuminate, projecting forward, and have a 

 peculiar twist at the base, which brings the outsides of these 

 two sepals on the same plane, their inner edges meeting together ; 

 the dorsal sepal and the petals are fringed w-ith silky hairs, 

 and the lip hangs so loosely that the slightest movement causes 

 it to rock freely. Philippines, 1840. (B. M., t. 4996.) 



C. graveolens. — This is now regarded as equalling C. Tobiis- 

 tum {Rolfe). 



C. picturatum {Lodd.). — -Though small in stature, this species 

 is very free. The pseudo-bulbs are ovoid, and the leaves deep 

 green. The scapes are thin and erect, bearing dense, circular 

 umbels of emerald-green flowers, spotted with red on the shorter 

 divisions ; the two lateral sepals are prolonged and united so as 

 to form a sleeve-like tube. It flowers in spring, and was intro- 

 duced about 1840 from Malaya. (B. M., t. 6802.) 



C. pulchrum (N. E. Br.). — A large - flowered species. 

 Dorsal sepal roundish, abruptly running out into a hair-like 

 point \m.. long, purpHsh, dotted with darker spots ; lateral 

 sepal connate into a convex oblong blade, \\\\-\. long, yellow, 

 mottled with purple ; scapes 4in. to 5 in. long, bearing about 

 seven flowers in an umbel. Leaves stalked, oblong - obtuse, 

 emarginate. Pseudo-bulbs short, distant, four-angled. Intro- 

 duced from Tropical Asia, 1886. 



C. robustum (Rolfe). — Flowers 2|-in. long ; sepals and petals 

 greenish-yellow, tinged with purple ; lip deep reddish-purple ; 

 scape very stout, bearing an eleven-flowered umbel, y^in. across. 

 Leaves thick and leathery, i3in. long, 4in. broad. Pseudo- 

 bulbs large, ovate, angled. New Guinea, 1893. Probably the 

 largest species known. Syn. C. graveolens. (B. M., t. 7557; G. C, 

 1895, ii., p. 771, fig. 116.)
