全 文 ：Anemone orthocarpa Hand.-Mazz. was described
on the basis of a collection, Cavalerie 4599 (K, P),
from Hoang-tsao-pa (= Xingyi County), southwestern
Guizhou Province, China[1]. This species is very rare
in China and has long been reported to be endemic to
the country[2–4]. In fact, after its fi rst collection in 1915
by Cavalerie the species was not collected again until
2006 when it was rediscovered from Xingyi, the type
locality[5].
Eichler[6], when dealing with the Ranunculaceae
from the Malesian region, mentioned in passing that
the specimens from Vietnam cited by Gagnepain[7]
(Suppl. Fl. Gén. Indo-Chine 1: 9. 1938) as Anemone
sumatrana de Vriese all belong to A. orthocarpa.
Regrettably this remark has been ignored or neglected
by all later authors of the genus Anemone.
Our comparison of the specimens of Anemone
orthocarpa from China with those from Vietnam cited
by Gagnepain[7] as Anemone sumatrana has confi rmed
that the specimens from Vietnam should be referred to
as A. orthocarpa (Fig. 1: A–C). The specimens from
Vietnam are not essentially different from those of A.
orthocarpa from China, but readily distinguishable
from A. sumatrana by the simple, deeply 3-divided
leaves with narrower middle lobes. In A. sumatrana,
the leaves are ternate, with the leafl ets petiolulate (Fig.
1: D).

Abstract: Examination of herbarium specimens has shown that Anemone orthocarpa Hand.-Mazz. (Ranunculaceae),
a species which was previously reported to be endemic in Xingyi County, southwestern Guizhou Province, China,
also occurs in Sa Pa District, Lao Cai Province, northern Vietnam.

Distribution and habitat. Anemone orthocarpa
is distributed in southwestern Guizhou (Xingyi),
southwestern China, and Lai Cai (Sa Pa), northern
Vietnam (Fig. 2). It grows in shady, moist places in
mountainous limestone karst areas at altitudes of 1000–
1200 m.
Notes. Relationships of Anemone orthocarpa
with other species of Anemone have been controversial.
Handel-Mazzetti[1] considered that the species is most
closely related to A. rivularis Buch.-Ham. This point
of view was accepted by Ziman et al.[8], who placed A.
filisecta C. Y. Wu ex W. T. Wang, A. orthocarpa and A.
rivularis within their series Rivularidum never formally
described. However, Eichler[6] regarded A. orthocarpa
as most closely related to A. sumatrana, and also more
or less related to A. begoniifolia H. Lév. & Vaniot, A.
chapaensis Gagnep., and A. howellii J. F. Jeffrey & W.
W. Smith. Wang[4] and Tamura[9] largely agreed with
Eichler[6] and referred A. begoniifolia, A. howellii, A.
hokouensis C. Y. Wu ex W. T. Wang, A. orthocarpa,
and A. sumatrana to the same section [A. sect. Bego-
niifolia (Ulbr.) Tamura]. Yuan and Yang[2] added to
the section their new species, A. xingyiensis Q. Yuan
& Q. E. Yang, the closest relative of A. begoniifolia.
Hopefully our ongoing molecular systematic studies
on Anemone can provide some useful information
for gaining a better understanding of relationships of
these species. It should be noted that A. chapaensis
from Vietnam has been determined to be conspecifi c
