A. YD THEIR LIANAGEMENT. 467 



Sobvalia. 



A'ar. Kienastiaiia has flowers "of the most exquisite purity, 

 surpassing all shades of white I have seen " (Reichenbach). 

 There is a small, sulphur-coloured mark near the base of the 

 lip. 



A ar. iiixna is much valued, being ot dwarf habit, with deep 

 purple and crimson flowers, quite as large as those of the type. 



"War. pallida has the sepals and petals soft rose, and the lip 

 almost white. 



5. sessilis (Lindl). — A rare and very beautiful species, 

 dwarfer in habit than the majority of Sobralias. Its reed-like 

 stems are from ift. to zh. in height, and the leaves are broadly 

 lance-shaped, tapering to a long, narrow point, and somewhat 

 hard m texture. One flower only is open on a stem at once, 

 and each lasts but a single day ; the stems, however, continue to 

 push forth a succession of flowers, so that during the flowering 

 season a fairly large plant is not long without bloom. The 

 spreading, oblong sepals and [petals are pure white, the latter 

 being slightly larger and broader. The lip is of a yellowish 

 colour, beautifully tinged with rose-pink ; the sides curl upwards, 

 and meet above the column ; the front lobe is expanded, and 

 prettily undulated at the margin. Each flower is 2in. across. 

 British Guiana; introduced in 1840. It flowers from October to 

 January. (B. jNL, t. 7376.) 



5. xantholeuca {Rchb. /.). — In general appearance this lovely 

 species differs but little from .S". macrantlia, exce[jt that, so far as 

 can at present be judged, it does not grow so tall. The sepals 

 and petals are narrowly oblong, and of a pale lemon-yellow, the 

 large frilled lip being of a deeper shade. This species was intro- 

 duced from Central America about 1881, and it still remains 

 extremely rare. It appears to possess the free-flowering character 

 of S. sessilis. (B. M., t. 7332.)
