which is far superior to the ordinary form. These plants are 

 very useful, as they are almost always in flower. 



C. viscosa. — At present this is a rare species ; it is nearly 

 allied to C. flaccida, it would seem, yet very distinct from that 

 plant. The pseudobulbs are fusiform in shape, bearing dark 

 gi-een leaves, which taper towards the base ; sepals and petals 

 white, lip white, the side lobes being broadly streaked with 

 rich brown. It blooms during summer. 



COLAX. 



A small genus, nearly related to Maodllaria, but separated 

 from them by a few trifling difi'erences. The species here 

 named is weU deserving attention. It should be potted in peat 

 and sphagnum with good drainage, and placed in the Cattleya 

 house. 



C. jugosiis. — A very interesting plant which flowered recently 

 in the rich collection of S. Rucker, Esq., under the care of 

 Mr. Pilcher. It grows about ten inches high, with leaves 

 two inches broad, and dark gi'een ; flowers two or three on a 

 spike, and about two inches in diameter ; sepals cream colour, 

 petals white, with numerous stripes of rich dark purple ; lip 

 white, smaller than the petals, and striped and spotted with 

 the same colour. It is a native of Brazil. 



Compare TTiA. 

 This is a small genus, of which the two species now 

 described are the best that have come under my notice. 

 They are veiy pretty plants, and distinct from any other 

 Orchids. They are best grown on blocks of wood, with hve 

 sphagnum moss, and suspended from the roof, with a liberal 

 supply of moisture in the growing season — in fact, they never 

 should be allowed to get dry, or they will sufier. The flowers 

 proceed from the base of the bulbs, and continue in beauty
