Background
The Gesneriaceae genus
Chiritopsis
, confined almost exclusively to cave or cave-like microhabitats of limestone karsts of southern China, was described to distinguish it from
Chirita
by much smaller flowers and generally miniature plant sizes in the former genus. However, molecular phylogenetic analyses showed that
Chiritopsis
is polyphyletic and its species delimitation has been problematic. To understand how many times Chiritopsis-like species have evolved from within the recircumscribed
Primulina
and to further clarify their species identification, we sampled all but two recently described species of Chiritopsis-like
Primulina
and reconstructed their phylogenetic relationship based on DNA sequences of nuclear ITS and chloroplast
trnL
-
F
and
trnH
-
psbA
.
Results
With 182 accessions of 165 taxa of
Primulina
sampled, our analyses placed the 40 accessions of 25 taxa of Chiritopsis-like
Primulina
in 17 unrelated positions, indicating at least 17 independent origins of the traits associated with caves or cave-like microhabitats. Of the 17 clades containing Chiritopsis-like
Primulina
, Clade 1 is composed of
P. bipinnatifida
,
P. cangwuensis
,
P. jianghuaensis
,
P. lingchuanensis
, and
P. zhoui
, as well as additional samples that show variable and overlapping morphology in leaf shapes. Clade 10 includes
P. cordifolia
,
P. huangii
, and
P. repanda
, while
Primulina repanda
var.
guilinensis
is not placed within Clade 10.
Primulina glandulosa
var.
yangshuoensis
is not placed in the same clade of
P. glandulosa
.
Conclusions
Based on our data,
P. cangwuensis
,
P. jianghuaensis
, and
P. lingchuanensis
are proposed to synonymize under
P. bipinnatifida
, with
P. zhoui
treated as a variety of
P. bipinnatifida
.
Primulina repanda

Primulina jiuyishanica K. Liu, D.C. Meng & Z.B. Xin, a new species of Gesneriaceae from Hunan, China, is described and illustrated. The new species is morphologically similar to Primulina fimbrisepala (Hand.-Mazz.) Yin Z. Wang, but differs in its elliptic to broadly elliptic leaf blade with broadly cuneate base, peduncle densely pubescent with sparse glandular hairs, corolla throat with no purple spots inside, the yellow patch in the throat densely glandular-pubescent and pistil densely glandular-pubescent. Photographs and descriptions of the new species are provided below.
“…In Li et al (2019) , five new species belonging to the genus Primulina were described. The correct collection dates and the type specimens numbers of these are as follows:…”
Primulina hochiensis var. ochroleuca, a new variety from a limestone hill of karst areas, Guangxi, China is described with color photographs. It resembles P. hochiensis var. hochiensis, P. hochiensis var. ovata and P. hochiensis var. rosulata, but can be easily distinguished by a combination of characteristics, especially by its corolla color. We found only one population with approx. 3000 mature individuals at the type locality. This variety is provisionally assessed as vulnerable [VU C1] using IUCN criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
