To sum up, the following results have been attained :— 
1, Restriction of Episcia to the section Cyriodeira, Bent = & 
Hook. f., which includes creeping herbs with spathulate-oblong 
calyx segments, a red (rarely pale lilac) corolla with a large flat 
limb, and placental lamellae bearing ovules on both surfaces. f 
2. Restoration of Centrosolenia to generic rank on the grounds of 
its different anthers and placentation, which were previously.

It_is doubtful. whether the relative length of the on is of 
ific importance in this genus as flowers in the same “ ‘head ” 
shove variability in this respect. The style of E. pine Sierenry
