Lindau has redistributed the species of Rung ia, Justicia, Himantochilus;, &c., by 

 the pollen; the Diclipterold group have " Spangen (banded) pollen," the .Tusticioid 

 have " Knotchen (tubercled) pollen." He attributes to Rungia " placenraj arising 

 elastically from capsule-base," while nothing is said under the genus Justicia re- 

 garding this character. Under this system, Rungia pubescens, T. Anders., appears 

 S).& Justicia paxiana, \j\iidi-An', Rungia grandis, 'i\ Awders., is returned to Kevv from 

 Berlin marked Justicia grandis (T. Anders.), Lindau; Rungia (?) pubinervia. T. 

 Anders., is published as Himantochilus marginatus, Lindau. Per contrn, Justicia 

 tedella, T. Anders., is called Rungia Baumannii, Lindau. The "banded'' pollen 

 appears to me separable by no definite line from the tubercled pollen ; the smooth 

 bands (in the centre of which are the pores) have often " obsolete" rows of marks or 

 dots which (in adjacent species) are slightly stronger and reckoned as tubercles. If 

 Rungia grandis and R. pubescens, T. Anders., are transferred to Juslicia, the genus 

 Rrnigia must be abandoned altogether.
