***GENDARUSSA. — Panicle terminal, or the axillary 
cymes running into an elongate terminal quasi-panicle. 
Bracts linear, shorter than the calyx, inconspicuous ; 
floral leaves (if any) remote from the calyx, at the 
principal divisions of the panicle. [N.B. There is no 
essential difference between the inflorescence of « 
species such as J. cordata and that of subgenus 
Rostellularia ; the primary branches of the “ panicle ” 
carrying small clusters of flowers at their tops are 
altogether homologous with the lateral branches carry- 
ing short terminal spikes in Rostellularia; the 
tangible difference is that in the subgenus Gendarussa 
the bracts are narrow, uot longer than the calyx. ]

SELLIA.—Spikes axillary, weak, unilateral, with few 
distant solitary flowers. Corolla small. Capsule small, 
ellipsoid, short-stalked, 4-seeded, very thin in texture ; 
seeds strongly rugose. These plants form a small, 
distinct, closely-allied group, and appear to me related 
to some American species of Dianthera (as D. ovata,
