A plant similar to P. strobilacea, Franch., to which I have 
attached it as a variety, and whose position appears to be doubt- 
ful in spite of its having the stamens inserted on the throat. 
It differs from P. strobilacea, Franch. by its 5-toothed calyx, 
short corolla tube and the beak straight or scarcely arched and 
much longer; there are no teeth on the lower edge of the hood. 
If the figure given by Maximowicz is correct it is easy to dis- 
tinguish at a glance var. riparia, Bonati from P. strobilacea, 
Franch. In var. riparia two staminal filaments are densely 
hairy, the two others are less so, but they are not glabrous; the 
hood has a very different shape in the two plants. 
Pedicularis cephalantha, Franch., var. szetchuanica, Bonati, 
Var. nov. 
Differs from the type by : 
The stems shaggy with hairs red at the tips; the leaves with 
petioles relatively longer and with the lobes broader (10-12 pairs 
of lobes 8 mm. long, 4-5 mm. broad); the membranous bracts 
dilated and long-ciliated at the base; the calyx invariably with © 
two teeth lanceolate-acute pinnatilobate with lobes obtuse and 
not numerous and with tube membranous and yellowish, deeply 
cleft in front, 7-8 mm. long; the tube of the corolla 13-14 
min. long; the hood not hairy on the back, but simply glandular 
less abruptly contracted into a beak about 5 mm. long, slightly 
bifid at the extremity. As in the type two of the staminal fila- 
ments are hairy and the lower lip is glabrous.

By the form of its calyx the above plant approaches P. oligan- 
tha, Franch. and P. lengepetiolata, Franch. but P. oligantha, 
_ Franch. has the lower lip ciliate and the staminal filaments all
