AND THEIR MANAGEMENT. 127 



Gcelogyne. 



plant, requirini; the same treatment as C. crisiata. (B. M., 

 t. 4SS9.) 



C. Swaniana {Rolfe). — An ally of C. Dayana, but having- 

 shorter pseudo-bulbs, leaves, and racemes. The flowers are white, 

 with a brown lip and yellow veinings. Philippines, 1894. (R. ii., 

 t. 92.) 



C. tomentosa (Li?iJ/.). — This species resembles C. Jlassaiig- 

 eana. It has pseudo-bulbs 2in. to 3in. long, and deep green; 

 leaves gin. to uin. long, plaited, ovate-lanceolate; flower-stalks 

 pendulous, tomentose, red-brown, bearing from fifteen to twenty 

 flowers, which are zhn. in diameter ; sepals and petals orange- 

 red ; lip obovate, three-lobed, the side lobes erect, white, with 

 red streaks, the mid-lobe square with three keels. It flowers 

 in spring. Native of Malaya, 1S70. 



C. Veitchii (Ro/fc). — This species is described in the " Kew^ 

 Bulletm"' as being "quite difi"erent from any previously known 

 species, in its short columns, the absence of markings on the 

 lip, and the very short, rather obscure, broad keels." The pure 

 white flowers are lin. across, produced in drooping racemes 

 2ft. long. Leaves lanceola:te, 6in. long. Pseudo-bulbs fusiform,, 

 4in. long. New Guinea, 1S95. 



COLAX. 



Lindley established the above-named genus of the 

 tribe Vandece. The name is derived from kolax, a parasite. 

 By many it is now referred to Lycaste. The chief point 

 of distinction lies in the shape of the flowers, which in 

 Colax is sub-globose, and the segments are broad and 

 spreading. 



Culture. — C. jugosus should be treated as a pot-plant, 

 the pots being thoroughly drained, and the compost 

 formed of living sphagnum and good peat, to which 

 may be added some medium-sized lumps of charcoal. 

 When potted, it should be placed in the Cattleya-house 

 and subjected to the same treatment as other Orchids 

 from the warm parts of Brazil. It likes plenty of water 

 during active growth. 



C. jugosus (Zz;7<//.).— This plant seldom exceeds ift. in height. 

 The pseudo-bulbs are smooth, and somewhat ovate, about 2m. long, 

 bearing a pair of dark green leaves, 6in. to gin. long, upon their 

 summit. The scape is erect, rising from the base of the pseudo- 

 bulbs, and produces two or three flowers, which are 2in. m
