108 BonaTI—PHTHEIROSPERMUM AND PEDICULARIS. 
Pedicularis siphonantha, D. Don, var. -birmanica, Bonati 
Var. nov. 
This differs from typical P. siphonantha, D. Don by its larger 
corolla with the median lobe of the lower lip more deeply bilobu- 
late and with the tube hairy on the outside, especially at the top. 
The beak relatively short is deeply bifid and the two lobes are 
almost perpendicular one to the other as they are in P. birostris, 
Bur. et Franch. All the other characteristics are those of typical 
P. siphonantha—calyx with three teeth, ciliate lip, two hairy fila- 
ments, etc. The corolla recalls that of P. Delavayi, Franch. In 
brief, this plant has the same relationship to P. siphonantha, D. 
Don as P. birostris, Bur. et Franch. has to P. cranolopha, 
Maxim.
