Notes
:—Without citing any specimens, Ho (1999) recorded that
Gentiana damyonensis
also occurred in Puge county in southwestern
Sichuan
. In the relevant Chinese herbaria, including CDBI, HNWP, IBSC, KUN, NWTC, PE, SM, SZ and WUK, we have been able to trace one PE sheet of
C.T. Kuan 8039
from Puge identified as this species by Ting-Nong Ho. Although the plants on the sheet are rather incomplete, with only basal stem leaves and broken and withered flowers, they are much taller (
20−30 cm
) than those of the true
G. damyonensis
, which are usually
5−10 cm
tall. This specimen was actually misidentified, and
G. damyonensis
does not occur in Puge.
