to the University of Leyden, under the name of P. zehrina, where, 

 under the able management of M. Witte^ the Superintendent, it 

 flowered for the first time in Europe in 1861, one plant only 

 surviving the journey. It was first introduced into this country by 

 Messrs. Low and Co. in 1864, and flowered for the first time in 

 the collection of the late Mr. John Day, at Tottenham, in the 

 summer of the following year. In 1881 it was detected by Curtis, 

 at that time collecting for us in the Malay Archipelago, in the hot, 

 damp forests of Palembang, growing on trees overhanging streams 

 and water- courses, generally on the trunks and much shaded, 

 sometimes associated with P. violaeea. 



The two last-named sub-varieties noticed above appeared among 

 Curtis' collection. Two others were noticed and named by Teijsman, 

 but which are now probably lost to cultivation. P. sumatrana 

 usually flowers in May and June. 



P. tetraspis. 



Leaves obovate, cuneate, 8 — 9 inches long and 2 — 3 inches broad. 



Peduncles much shorter than the leaves, 3 — .5 flowered. Flowers IJ — 2 



inches in diameter, ivory-wliite, the pedicels sheathed at the base by a 



small triangular deciduous bract ; sepals and petals similar, spreading, 



oval-oblong, acute, the two lateral sepals broader than the dorsal one ; 



lip fleshy, three-lobed, the side lobes ligulate, curved upwards and inwards, 



truncate at the free end, yellowisli on the outer side ; the front lobe 



sub-rhoraboidal, with a tuft of bristles at the apex ; crest sub-conic. 



Colimin swollen at the base.

Originally discovered by Thomas Lobb, while collecting for us in 

 Malaysia, who gave no locality, and whose dried flowers were com- 

 municated by us to the late Professor Reichenbach. The first living 

 plants received in this country were sent to Mr. William Bull, of 

 Chelsea, in 1881, by Major-General E. S. Berkeley, who had detected 

 them in the Andaman Islands, " growing on Mangrove and other trees 

 ill muddy swamps, at the extreme end of the creeks, where the water 

 is fresh, and where the plants hang from the branches a few feet 

 above the water, growing with extraordinary luxuriance."*
