Primulina lutvittata
Ann. Bot. Fennici
Primulina lutvittata Fang Wen & Y.G. Wei, a new species of Gesneriaceae from Guang-
dong, China, is described and illustrated. It is morphologically similar to P. fengshanen-
sis, but differs by several characters of the leaves, cymes, bracts, corollas and anthers.
Recently, after a molecular re-evaluation of the
genus Chirita, previously monotypic Primulina
has been redened to contain more than 130 spe-
cies (Wang et al. 2011, Weber et al. 2011). Over
the last few years, we carried out oristic surveys
on the limestone caves in S and SW China, in
Guangxi, Guangdong, Yunnan, Guizhou, Hunan,
Hubei, Zhejiang, Jiangxi, Anhui and Chongqing,
and found some unknown species of Gesne-
riaceae. One undescribed species from Guang-
dong was considered to belong to newly circum-
scribed Primulina, after thorough consultation of
the literature (Wang et al. 1990, 1998, 2011, Li
& Wang 2004, Xu et al. 2009, Liu et al. 2010,
2011, Pan et al. 2010, Wei et al. 2010, Huang
et al. 2011, Shen et al. 2011, Tang & Wen 2011,
Weber et al. 2011, Wu et al. 2011a, 2011b, 2012,
Xu et al. 2011a, 2011b, 2011c, 2012, Hong et al.
2012, Huang et al. 2012, Li et al. 2012, Wen et
al. 2012a, 2012b). This species is described here.
Primulina lutvittata
sp. nova
Type: China. Guangdong province, Yangchun county,
22°37´N, 111°50´E, in large limestone caves, alt. 70–84 m,
owering, 29 June 2011 F. Wen 11062901 (holotype IBK;
isotypes IBK, BJFC).
It differs from P. fengshanensis in: leaf blade
eshy-leathery and sparsely erect-hirsute; cyme
unbranched or 1-branched, rarely 2-branched;
bracts opposite, 2, outside sparsely erect-hirsute
and inside glabrous; corolla throat with two dis-
tinct bright-yellow stripes; anthers sparsely pubes-
cent; laments sparsely glandular-pubescent and
the upper surface of stigma densely puberulous.
Perennials, acaulescent. Rhizome cylindrical,
1.8–3.0 cm long, 0.9–1.3 cm in diameter, gla-
brous, internodes inconspicuous. Leaves spirally,
8–24, basal or clustered at apex of rhizome, ter-
nate; petiole cylindrical, above recessed, cross-
section -shaped, hirsute, 2.1–4.3 ¥ 0.8–1.2 cm;
blade fresh eshy-leathery, obovate-elliptical,
obovate-lanceolate, narrowly elliptical to slightly
ovate, 6.0–13.5 ¥ 2.2–3.8 cm, base attenuate
to cuneate, margin entire, occasionally incon-
spicuously crenate, apex acute or acuminate,
sparsely erect-hirsute on both surfaces, lateral
veins ca. 3 on each side, inconspicuous adaxially
and prominent abaxially. Cymes axillary, 3–12,
Wen et al.
unbranched or 1-branched, rarely 2-branched,
generally 1-owered, occasionally 2–3-ow-
ered, rarely more than 4–5-owered; peduncle
7.5–12.4 cm long, 0.1–0.15 cm in diameter,
erect-hirsute; bracts 2, opposite, broadly lanceo-
late to lanceolate-ovate, 1.7–2.0 ¥ 0.5–1.1 cm,
abaxially hairs same as peduncle, adaxially gla-
brous, margin entire, apex acute. Pedicel 1.4–2.1
cm long, 0.8–1.0 mm in diameter, puberulent.
Calyx 5-divided nearly to base; lobes equal,
lanceolate-linear to lanceolate, 6–8 ¥ 1.5–1.8
mm, abaxially sparsely hirsute, margin entire,
apex acute. Corolla bright purplish-red, fuch-
sia or deeply peach-coloured, throat with two
distinct bright-yellow strips, 1.8–2.2 cm long,
orice 0.6–0.8 cm in diameter, abaxially short
pubescent-glandular, adaxially glabrous; tube
narrowly infundibuliform, 1.4–1.5 cm long; limb
distinctly 2-lipped, adaxial lip 2-divided to base,
lobes slightly oblique ovate, 4.5–5 ¥ 4.8–5.0
mm, obtuse at apex, with 8–10 dark purple or
peach-coloured lines inside; abaxial lip 3-divided
to middle or slightly over middle, lateral lobes
slightly oblique-oblong, 5 ¥ 4.5 mm, obtuse at
apex, with 3–5 dark purple or peach-coloured
lines inside, central lobe oblong, 6–7 ¥ 4–4.5
mm, obtuse at apex, with 5–6 dark purple or
peach-coloured lines inside. Stamens 2, adnate
to ca 1.0 cm above corolla base; anthers yellow
or slightly orange, subreniform, 2.5–3 ¥ 1.0–1.1
mm, slightly constricted at middle, sparsely
pubescent; laments geniculate close to middle,

6–7 mm long, sparsely glandular pubescent;
staminodes 2, short linear, glabrous, 1.8–2.2 mm
long, adnate to 6.5–7.0 mm above corolla base,
capitate at apex; disc annular, 0.4–0.5 mm high,
margin entire or sometimes slightly erosulate.
Pistil 2.2–2.5 cm long; ovary linear, 1.4–1.6 mm
long, ca. 1.5 mm in diameter, densely puberulent;
style 7.0–8.0 mm long, 0.5–0.6 mm in diameter,
puberulent. Stigma green, obtrapeziform, upper
surface densely puberulous, apex slightly lobed,
2.4–2.6 mm long. Capsule dehiscent, linear, 2.0–
2.5 cm long, ca. 2 mm in diameter, pubescent
when young, style persistent, straight.
Primulina lutvittata is rather similar to P.
fengshanensis; a detailed comparison of the two
species is in Table 1.
