the section Nautilocalyx provisionally to Alloplectus ; and the three 
species received from Messrs. Sander & Sons were accordingly 
described under the names Alloplectus (Nautilocalyx) Forgetii, A. 
pallidus and A. hirsutus (Kew Bull. 1910, p. 383; 1911, p. 346). 
The result of a further investigation is now given. 
The genera Episcia and Alloplectus were distinguished from each 
other in Benth. & Hook. f., Gen. Plant. vol. ii. 1876, p. 993, key 
to the genera, by the filaments, which were stated to be free from 
one another in the former, and united into a posticously split sheath 
in the latter ; on p. 1006, however, they were described as more or 
less connate at the base in Episcia. In the original description of 
Episcia (Martius, Nov. Gen. et Sp. Pl. vol. iii. 1829, p. 39) 
the filaments were stated to be subulate, and inserted at the very 
base of the corolla, and they were figured as free from one another 
in E. reptans (t. 217). anstein, however, in his conspectus of the 
enera of (Gesneriaceae (Linnaea, vol. xxvi. 1853, pp. 206-207) 
was doubtful as to whether the filaments were not united at the 
base, and eleven years later he definitely described them as united 
at the base among themselves and with the base of the corolla, as 
in Alloplectus (Martius, Fl. Bras. vol. viii. pars 1, 1864, p. 401). 
This has been confirmed by the writer. 
narrower or not much broader than the tube. 
Inspection of the specimens of Episcia in the Kew herbarium 
suggested that that genus, as defined by Hanstein (Linnaea, vol. 
_ xxxiv. p. 246), Bentham and Hooker, and Fritsch (Engl. and 
Prantl, Nat. Pflanz. vol. iv. 3b, p. 166), included several discordant 
elements which made it impossible to define the genus satisfactorily. 
gure. 
On carefully comparing the figures of Episcia reptans and 
Alloplectus sparsiflorus, it was noticed that the placental lamellae 
bore ovules on both surfaces in the former, and on the inner surface 
only in the latter. If the presence of ovules on both surfaces of 
the placental lamellae be accepted as characteristic of Episcia, the 
genus can be restricted to the section Cyriodeira (Euepiscia), Benth. 
Hook. f., including the following species: £. reptans, Mart. 
(Nov, Gen. et Sp. vol. iii. t. 217), E. cupreata, Hanst. (Bot. Mag. _
