Diospyros brandisiana Kurz (Ebenaceae), A Newly Recorded Species from China

中国柿树科植物一新记录种——长柱柿



全 文 :Diospyros L. is the largest genus of about
450 – 500 species of evergreen and deciduous trees
in Ebenaceae, mainly distributed in pantropical and
temperate regions[1–4]. In China, there are 57 – 60
species (six varieties, one form, one cultivated species).
Several species are known only from limited localities
of SE and SW China[1]. In the genus, some of the
species are important as economic plants in China[5–6].
During some surveys on the seed plants in the
Yuanyang and Jinping Counties of southeastern
Yunnan, we collected some specimens of Diospyros
with cauliflory habit, alternate and distichous leaves,
bisexual flowers, long simple crass style and persistent
calyx. The combination of features indicated that it is
a new member of Diospyros, which had not been
recorded to China[1]. By consulting some publications,
we confirmed that it is Diospyros brandisiana Kurz,
which is common in Southeastern Asia[1–4].

Abstract: Diospyros brandisiana Kurz (Ebenaceae) is reported as newly recorded species to China. Its diagnostic
characters, habitat and distribution are discussed. Its cauliflory habit is unique among the species of the genus
Diospyros in China. The voucher specimens are deposited in Herbarium of Kunming Institute of Botany, Chinese
Academy of Sciences (KUN).

black, cauliflorous; branches pubescent when young,
glabrescent when mature. Leaves alternate; petioles
puberulous, 0.5 – 1.7 cm; blades chartaceous, oblong
to lanceolate, 12 – 24 cm × 4.5 – 7.8 cm, apex acuminate,
base attenuate, margin entire, glabrous on both sides,
appressed pubescent along the veins, midrib flat above,
secondary veins 13 – 17 pairs. Cyme born on trunks,
1-many-flowered. Flowers white and smooth inside,
greenish and sparsely black tomentose outside, penta-
merous or occasionally tetramerous. Pedicels 1.7 –
5.8 mm, tomentose. Bracts lanceolate, 0.6 – 1.4 mm
long, tomentose. Calyx commonly 5-lobed, lobes 2.1 –
3.4 mm, brown tomentose. Corolla campanulate, 7 –
9 mm, tube ca. 12 mm, brown villous, commonly
5-lobed, lobes oblong, 5 – 7 mm × 3 – 4 mm, apex
obtuse. Ovary pubescent, 10-locular, style simple and
robust, 0.6 – 1.2 mm long, stigmas 5 – 6 papillose.
Berries somewhat leathery, global, black pubescent,
xyloid and 3 – 4 cm diam. When mature, persistent
style 1.8 – 2.5 mm long.
Phenology: Flowering from February to April,
fruiting from May to August.
Habitat: It is found in tropical seasonal forest at
the elevation of 700 – 900 m.
Distribution: Diospyros brandisiana Kurz is
distributed to China, India, Myanmar, Laos, Thailand,
Vietnam and Malaysia. It is newly recorded to China
occurring in southeastern Yunnan.

D. brandisiana differs from all Chinese species
by long simple crass style and persistent stigma (Fig. 1:
D), cauliflory (Fig. 1: A, C) and puberulous petioles
(Fig. 1: B). So far, D. brandisiana is the only species of
Ebenaceae in China with cauliflory (Fig. 1: A). Sutee
Duangjai et al. used six regions plastid DNA sequences
data (2006) and eight regions plastid DNA sequences
data (2009) to infer the phylogeny of Diospyros, and
investigated that D. brandisiana and D. curranii are
sister relationship species[7–8].
