No one can compare this lovely plant with its gorgeous 
congeners, O. vevillarium (Tab. nost. 6037) and O. Phalaenopsis, 
without recognising with Professor Reichenbach their close 
affinity in foliage and habit, whilst in floral structure they 
differ materially, especially in the lip, which in O. vexillarium 
has the claw produced backwards into an acute horn on 
either side, whereas in this it is quite simple. The ridges of 
the claw and disk of the lip farther differ remarkably, as a 
comparison of the plates will show. 0. Warscewiceit was dis- 
covered by Joseph von Warscewicz, the Polish nobleman who 
has added so many fine plants to our stoves, in Costa Rica ; 
it was first flowered by Messrs. Veitch, in February of this 
year, and by them sent for figuring in this Magazine. It is 
a very free’ bloomer, and may, as Dr. Reichenbach suggests, 
rival O. vewillarium itself in the estimation of florists. Its 
discoverer describes it as growing at a considerable elevation, 
and being very scarce. 
Descr. Pseudobulbs tufted, small, one and a half to two 
inches long, oblong-ovate, compressed, margins acute. Leaves 
distichous, nearly a foot long, elliptic-lanceolate, acute, bright- 
green above, paler beneath and keeled. Scape about as long
