Notes:
—Based on two collections from northern
Vietnam
, Nguyên & Yakovlev (1982: 108) published the name
Rubus caudatisepalus
T. H. Nguyên & Yakovlev
, which they placed it in sect.
Corchorifolii
Focke (1911: 129)
. The name
R. caudatisepalus
, however, had been previously used by
Calderón (1973: 57)
for a different Mexican species. Thus Nguyên & Yakovlev’s name is a later homonym of
R. caudatisepalus
Calderón
and illegitimate. A replacement name (nomen novum),
R. nguyenii
Huan C. Wang
, is proposed here.
Rubus nguyenii
Huan C. Wang
is very similar to
R. corchorifolius
Linn.
f., a species widespread in
East Asia
, but differs from the latter by its stems nearly glabrous, leaves long acuminate at apex, lateral veins of leaves 9-11 pairs, sepals caudate at apex, styles pilose at base, and fruits nearly glabrous. This species has so far been reported only from northern
Vietnam
(Nguyên & Yakovlev 1982,
Averyanov & Nguyên 1996
), here two gatherings (
Sino-Russ Exped.1128
and
P. Y. Mao 03504
) from southeastern
Yunnan
,
China
, are first reported for the flora of
China
.
