This species should strictly bear the name of P. nanum, having been so
called and clearly defined by W e i s s in 1770 in his excellent “ PL crypt. Fl.
gotting; ” but seeing that later authors have transferred the name to the preceding
species, it would lead to endless confusion to retain it. Th e plant is
taller and more branching than P. siibrotimdum, and like it presents several
different forms, the serration varying in extent, and size of teeth and sometimes
being nearly obsolete on the back of the nerve ; in P. rubellum M e n z . it
is very distinct, and the stems also are taller and more branched.
Occasionally both stems and set^ become greatly elongated, a state which
appears to be frequent in N. India and Japan.

This species varies somewhat in size and colour, and the capsules
occasionally are a little asymmetric ; the papillæ extend over the lower part
of the lid.
