somewhat fleshy and of a bright green colour. The peduncles

 two and a half" inches across, and rather more in depth ; the 

 oblong sepals and cuneate-oblong petals yellowish white, 

 transversely barred with rich reddish brown ; the lip narrow, 

 three-lobed, its lateral lobes terminated behind in a curved 

 tooth, 3'ellow in front, and the middle lobe ligalate oblong, 

 keeled, with four lines of violet-purple, two on each side the 

 dense tuft of hairs which runs out to the apex. " The

Syn. — P. zehrina. 



P. tetraspis, Rchb.f. — -A chaste beautiful very free-flowering 

 species, in growth resembling P. sumatmna, the stem bearing 

 but few leaves. The leaves are dark green, stout, cuneate- 

 obovate oblong acute, and the flowers, which are said 

 to have a fine perfume, are produced in rich drooping pani- 

 cles, and have the general shape of those of P. sumatrana. 

 They are ivory or waxy white, shining, with a trifid lip, of 

 which the erect retuse side lobes have each a blotch in the 

 centre, and the convex ligulate central lobe bears a large felt- 

 like cushion. It flowers during the summer months. — India :

P. Valentini, Rchh. f. — This plant is probably a natural 

 hybrid between P, Cornu-cervi and P. violacea. The flowers 

 are larger than those of the former species and smaller than 

 those of the latter. The leaves are light green, narrower 

 than in P. violacea, and without the wavy crispness usually 

 seen in that species. The sepals and petals are cuneate- 

 oblong, purple, the lateral sepals and petals white at the base 

 inside and marked with purple bands ; the lip is similar to 

 that of P. violacea, the side lobes with a spreading angle at 

 the upper corner, white with purple spots on the upper 

 border, the front lobe pandurate, three-parted at the top, 

 which is mauve, and bearing a thick umbo in the middle ; 

 the disk is yellow, as also is the column, the latter with red 

 stripes at the top. — Malayan Archipelago. 



P. YeitcMana, Rchh. f. — This species is supposed to be 

 a natural mule between P. rosea and F. S chiller iana. The
