Abstract Staurogyne petelotii Benoist and S. vicina Benoist (Acanthaceae) are reported to
be new records in China.
Key words Staurogyne, Staurogyne petelotii, Staurogyne vicina, Acanthaceae, new record,
Yunnan, China.
The Acanthaceae are very richly represented in the southeastern Yunnan Province,
China, with nearly half of the species in China occurring there (Hu, 2002; Shui & Chen,
2003). Nine species in the genus Staurogyne Wall. have been reported from that region. They
are S. brachystachya Benoist, S. chapaensis Benoist, S. hypoleuca Benoist, S. longicuneata H.
S. Lo, S. petelotii Benoist, S. rivularis Merr., S. sesamoides (Hand.-Mazz.) B. L. Burtt, S.
vicina Benoist and S. yunnanensis H. S. Lo (Benoist, 1935; Ho, 1993; Hu, 2002; Shui &
Chen, 2003). Staurogyne petelotii and S. vicina are newly recorded in China.

Herb, 10–30 cm tall, base ascending. Stems erect, densely pubescent, simple, rarely
branched in the upper part, base with 1.5–3.0 cm long internodes. Leaves opposite and borne
on stem; blade ovate or oblong, membranous, 3–6 cm long, 2–3.5 cm wide, base widely
cuneate or rounded, apex obtuse, sparsely pubescent on upper surface, glabrous and pale on
lower surface; petiole 2–4 cm long, pubescent. Inflorescence racemose, terminal, simple;
bracts obovate, ca. 8 mm long, ca. 4 mm wide, base attenuate, apex rounded, margin ciliate in
the upper part, sparsely pubescent on lower surface; bracteoles oblong, ca. 6 mm long, ca. 1
mm wide, base gradually attenuate, apex rounded, margin pubescent especially in the upper
part; calyx lobes 5, unequal, the larger one ca. 5 mm long, ca. 0.5 mm wide, the lateral 2
linear-oblong, smaller, ca. 3 mm long, ca. 0.25 mm wide, apex slightly enlarged and rounded;
corolla tubiform, incurved, prolonged, 1.5–1.7 cm long, base 1.5–2.0 mm diam.; corolla lobes
5, orbicular, ca. 5 mm long and wide; stamens 4, included. Ovary glabrous, style glabrous,
18–19 mm long, apex bifid. Capsules long ellipsoidal, ca. 7 mm long, glabrous, gradually
attenuate upward.

No. 4 CHEN W-H et al.: Staurogyne petelotii and S. vicina, two new records of Acanthaceae from China 465

Distribution: China (SE Yunnan), Vietnam (Chapa). New record to China.
Ecology: under forest along ravine or on slope, alt. 1400–1700 m.
Note: Staurogyne petelotii is very similar to S. chapaensis Benoist in the spathulate calyx
and the incurved corolla tube, but differs by having stem obviously erect, 10–30 cm long,
base with internodes 1.5–3 cm long, leaves borne on stem, base widely cuneate or rounded,
corolla 1.5–1.7 cm long, base 1.5–2 mm diam. In S. chapaensis, the stem is 1–3 cm long, with
internodes 0.3–0.5 cm long, the leaves are basal, base cordate, the corolla is 2–2.7 cm long,
base 3–5 mm diam. The type locality of S. petelotii, Chapa, northern Vietnam, is near
southeastern Yunnan, China, divided only by the Honghe River.

密花叉柱花 新拟
Herb, ascending, higher than 20 cm. Stem erect, simple, pubescent in the upper part,
tuberculate in the lower part. Leaves opposite, subterminal, lanceolate, 6–15 cm long, 3–4.5
cm wide, base acute, apex acute or short acuminate, margin entire or serrate, only pubescent
along nerves on both surfaces; petioles 2–4 cm long, pubescent. Inflorescence terminal,
racemose, simple, elongated; peduncle glabrous, 6–15 cm long; petiole 2–2.4 mm long,
pubescent; bracts linear, 4–5 mm long, subglabrous; bracteoles linear, subglabrous, ca. 2 mm
long; calyx lobes 5, linear, ca. 5 mm long, unequal, herbaceous, apex obtuse and with red dots
outside; corolla white, 1.8–2.1 cm long, glabrous on lower surface; corolla tube 1.4–1.7 cm
long, lobes subequal, semi-orbicular, ca. 4 mm long; stamens 4, didynamous. Ovary glabrous,
style glabrous, apex bifid. Capsules unknown.
China. SE Yunnan (云南东南部): Hekou (河口), C. Wang et al. (王孝等) 100305 (IBSC).
Distribution: China (SE Yunnan), Vietnam. New record to China.
Note: Staurogyne vicina is similar to S. hypoleuca Benoist in the lanceolate leaves with
cuneate base, and the terminal and simple raceme, but differs by having corolla 1.8–2.1 cm
long. In S. hypoleuca, the corolla is ca. 7 mm long. It is not surprising that S. vicina was found
to occur in SE Yunnan, because its type was collected from Chapa, northern Vietnam, a
region very near southeastern Yunnan, China.
