C. palustris differs from other species of the genus in 
the strongly: twisted anthers, in which character it ap- 
proaches the European genus Frythrea, of which the 
purely South African genus Chironia may be regarded as the 
strict representative, differing chiefly in the stigma, which, 
though often two-lobed, is never broadly: two-lamellate. 
The spirally twisted stamens and straight style of C. 
_ palustris have led to its being first sectionally separated 
by Grisebach in his Monograph of Gentianew, as sect. 
Pseudo-Sabbatia, and latterly generically separated by E. 
Meyer under the name of Plocandra. As, however, 
Bentham has pointed out, the anthers are at length twisted 
in a true Chiron‘a, C. peduncularis, and the style is cer- 
tainly curved in Plocandra palustris. 
Under C. peduncularis, Plate. 7047, I have given some 
* statistics of the cultivation of the Cape Chirodnias in Eng-- 
land, with the names of all known to have been introduced. 
-T'o these the present species is a very handsome addition. 
It is a native of the Eastern districts only, extending from 
Natal northward to the Limpopo or Crocodile River, 
which bounds the Transvaal on the north in Lat. 22°S., 
and southward to East London in Lat. 33° S., where Mr. 
Watson in 1887 eollected seeds from plants ‘growing _
