The nearest ally of this Orchid is assuredly the Huntleya 
cerina, Lindl, (Tab. nost. 5598), which differs conspicuously 
in colour and in the form of the semi-circular callus at the 
base of the limb of the lip, and which is referred, along with — 
other species of Pescatoria, to a section of the old genus 
Zygopetalum, Hook., by the younger Reichenbach, in the 
sixth volume of Walper’s “ Annales,” p. 651. The said 
section is, however, characterised by having a slender semi- 
cylindric column, whilst the column both of P. cerina 
and of P, Dayana is broad and boat-shaped, as in Bollea 
(Reichenbach’s first section of Zygopetalum). In the present 
state of Orchidology it is not possible for the Botanist or the 
Horticulturist to speak with confidence of generic limits in 
any considerable group. I have retained this under Pescatoria, 
following Reichenbach (in the ‘Gardener's Chronicle,’ 
l.c.), by whom the genus (usually wrongly written Pescatorea) 
was founded. As above observed, however, this genus has 
been referred by him to Zygopetalum as long ago as 1861, 
together with Bollea, Warscewiezella, Warrea, Keferstema, 
and Promencea. ee 
Pescatoria Dayana has several varieties in cultivation, 
depending on the markings on the perianth being absent,
