Abstract: Primulina huangjinianaꎬ a new species of Gesneriaceae from Mount Danxia of Guangdong Province in Chinaꎬ
is described and illustrated here. The new species is easily distinguished from the most morphologically similar species
P. depressa by its shorter bracts 2.5-6 mm long (vs. 15-30 mm long)ꎬ subequal (vs. unequal) calyx lobesꎬ filaments
with glandular puberulence above the middleꎬ and geniculate near the base (vs. glabrous and geniculate near the mid ̄
dle)ꎬ stigma obdeltoidꎬ deeply 2 ̄lobed with two linear lobes (vs. lamelliformꎬ slightly 2 ̄lobed with two acute ̄triangular
lobes)ꎬ and parietal placenta (vs. axile placenta). Including this new speciesꎬ there are six Primulina species recorded
in Mount Danxia. Among themꎬ P. danxiaensis and P. huangjiniana are endemic to Danxia landform. Only two popula ̄
tions of P. huangjiniana were found with no more than 200 mature individuals in Mount Danxia. This new species could
be considered as Critically Endangered (CR) according to IUCN Red List Criteria.
