recently brought together under the old generic name 
Nautilocalyz. The species in question agree with Episcia 
as to habit and in general facies, but differ from members of 
that genus in having ovules only on the inner surface 
of the placental lamellae. From Alloplectus they are 
readily distinguished in being herbs and in having a 
relatively large corolla-limb. The mussel-shaped anther- 
thecae serve to separate them from the closely allied genus 
Centrosolenia. The plant from which the material for our 
figure has been obtained was presented to Kew by Messrs. 
F. Sander & Sons, St. Albans, to whom it had been sent 
from Peru by their collector Mr. Forget. It grows freely 
under warm greenhouse conditions and forms numerous 
stems which flower more or less continuously throughout 
the summer, It is easily propagated by means of cuttings; 
it also ripens seeds. There are two other species of 
Nautilocalyx in cultivation, both readily distinguishable 
from NV. pallidus in having yellow flowers and leaves 
purple beneath. One of them, NV. Lynchii, has been figured 
in this work, at t. 7271, as Alloplectus Lynchii; it has 
smooth leaves and has calyx-seements much shorter than 
the corolla-tube, and is thus readily distinguished from the 
other, V. bullatus, often known as Episcia tesselata, which 
has bullate leaves and calyx-segments nearly as long as the 
corolla-tube.
