Closely resembles a large state of T. cordifoUa in habit and foliage, but the calyx 

 is longer and narrower, with the wings produced on the pedicel, never cordate at 

 the base, and the capsule is longer and narrower. The plate in Bot. Mag. is very 

 characteristic. Hamilton's T. alba is, I assume, a white-fld. variety. 



5. T. aslatioa, lAnn. ; Wight Ic. t. 862 ; nearly glabrous or pubes- 

 cent; diffuse, creeping belovf, leaves shortly petioled ovate-oordate or -lanceo- 

 late serrate, pedicels axillary and subumbellate fruiting thickened, fruiting 

 calyx 1 in., narrowly oblong keeled hardly winged, base decurrent, corolla 

 li-li in. blue with very dark violet lateral lobes, longer filaments toothed.

Except by the usually more diffuse habit, the not winged calyx and the always 

 itoothed longer filaments, I do not see how this can well be distinguished from T. 

 pedtmcularis. The flowers are much smaller than in T. asiatica and of a more uni- 

 form blue, and the leaves also are smaller. I cannot distinguish T. rulens as a 

 variety ; the characters assigned to it are the short obtuse tooth of the longer fila- 

 ments, and often red tips to the calyx teeth.
