153. S. viOL-EFOLius, T. Anders, in Journ. Linn. Soc. ix. 485 ; leaves petioled 

 obliquely ovate acute serrate subglabrous, spikes few-fld., flowers distant subsessile in

 1 in., filiform ; upper leaves sessile, 1&-3& by 1-1 in. Spikes 3-4 in., terminal on 

 lateral branches ; bracts - in., linear sometimes spathulate, herbaceous ; bracteoles

154. S. ? LANATTJS, Nees in DC. Prodr. xi. 191 ; leaves ovate acuminate entire 

 glabrate above woolly-tomentose beneath, spikes axillary and terminal ternate cylindric 

 dense, bracts oblong obtusely cuspidate woolly-tomentose beneath glabrous lanceolate 

 above. 



NILGHEEBIES ; Perrottet. 



Very distinct from the stem, petioles under surface of leaves and spikes being 

 densely softly tomentose. Corolla-tube 1 in., slender, throat campanulate, approaching 

 that of Stenosiphonium. Calyx sub-5-partite ; segments linear, obtuse, very villous. 

 Genus doubtful : referred to Rtrobilanthes from its similarity to S. Mysurensis, 

 Nees, which is an Asystasia. 



S. VEBEUCULOSTJS, Nees in DC. Prodr. xi. 181, from "India" remains obscure; 

 Nees doubts whether it may not have been a Ruellia.
