****GENDAETJasA. — 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 diflference between the inflorescence of h 

 species such as J. cordata and that of subgenus 

 Bostellularia ; the primal'y 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 RostellulaHa ; the 

 tangible diflference is that in the subgenus Gendarussa 

 the bracts are narrow, not longer than the calyx.] 

 Panicle linear, nearly continuous (a very glabrous 



shrub) 56. J". Oendanissa. 



Panicle more lax, with the lateral cymes more or less 

 evolutc.

Ansellia. — Spikes axillary, weak, unilateral, with ^qw 

 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,
