Phaius. 



in an intermediate-house temperature, when it will flower in 

 summer. Madagascar, iSSo. (Fig. 143, for which we are 

 indebted to the Editor of " The Gardeners' Chronicle.") 



Var. alhijiora. — A most distinct and beautiful variety ; the 

 sepals and petals pure white, the lip deep purple, instead of 

 brown, as in the type. (Fig. 144.) 



P. maculatus (LindL). — One of the few Orchids having 

 variegated foliage ; its flowers are also very beautiful. The 

 pseudo-bulbs are 2in. high, furrowed, and ovate. The plaited 

 leaves are ijft. to 2ft. long, by about 4in. wide, tapering at each 

 end ; they are dark green, freely marked with large, roundish, 

 yellow spots. The flower-stems are lift, to 2ft. high, and towards 

 the top bear ten to fifteen flowers, rather closely arranged. The 

 flowers are 2in. to 3in. across, with the oblong sepals and petals 

 of a clear, soft yellow, and the cylindrical lip also yellow, but 

 streaked with reddish-brown on the edges of the middle lobe. 

 This species is a native of Northern India and Japan, and 

 succeeds well in an intermediate-house. It was introduced in 

 1823. Syn. Bletia U^oodfordii. (B. JM., tt. 2719 and 3960.) 



P. Marshalliana {Nichols.). — A synonym of Thiuiia Marshallia. 



P. Sanderianus (Hort.). — A synonym of P. Maniiii Wallichii. 



P. simulans {Rolfi). — This species is very nearly allied 

 to F. tuberculosiis, and has been cultivated in gardens for 

 it until quite recently, but the growth is more bulbous in 

 the true species. Its small, slender pseudo-bulbs spring from 

 a rhizome-like stem that emits roots freely. The leaves are 

 from 6in. to 9in. long. The flowers are borne on erect 

 spikes, and are each 2!in. in diameter, with pure white sepals 

 and petals, the latter overlapping the slightly narrower sepals. 

 The beautiful lip is three-lobed; the lateral lobes are yellow, 

 almost covered with dull brownish-crimson spots, and arched 

 over the slender, curved column ; the central lobe is smaller 

 and roundisli, divided at the apex, wavy, and white, spotted 

 with rosy-purple. A native of Madagascar, whence it was intro- 

 duced in 1S80. As before intimated, this species is a difficult 

 plant to grow successfully. It requires a higher temperature than 

 the other species, and should have a shady, moist position in the 

 tropical house. It thrives when fastened to an upright raft, with 

 a tuft of living sphagnum about its rhizomes. (Fig. r45.) 



P. tuberculosus {Blame). — Rhizomes tufted, ovoid, and 

 ringed. Side lobes of the lip without hairs, the three deep 

 yellow keels 2\ lines long being somewhat verrucose, high and 

 truncate in front, and thus club-shaped, the middle one
