Abstract:

 (1) The confusion of the circumscription of Aconitum delavayi Franch.,
an alpine  erect species endemic to the Mt.  Maershan,  province Yunnan,
which was brought about by Finet & Gagnep. and Handel-Mazzetti with an inclu-
sion of a lowland twinning species, Aconitum episcopale Lévl., is clarified. Three
Chinese specimens cited by Handel-Mazzetti under Aconitum baicalense Turcz. ex
Rapaics in fact  represent three taxa of the genus Acontium other than A.
baicalense. Examination of the type specimens shows that Clematis grata Wall.
var. grandidentata Rehd. et Wils., with pinnate leaves and few-flowered axillary
inflorescences, was erroneously referred to C. grate Wall. var. argentilucida (Lévl.
et Van. ) Rehd., with ternate leaves and many-flowered axillary inflorescences, by
Rehder. As a matter of fact, the former represents an independent species related
to C. grata Wall. and should be raised to specific rank, and the latter should be
a variety of C.  apiifolia DC.,  being identical with C.  apiifolia DC. var.
obtusidentata Rehd. et Wils. (2) Aconitum delavayi Franch. var. leiocarpum Finet
et Gagnep. (=A. contorum Finet et Gagnep. ), A.  vilmorinianum Kom. var.
altifidum  W.  T.  Wang (  =A.   episcopale  Lévl.),  Delphinium  leptopogon
Hand-Mazz. (=D. siwanense Franch. ), D. calleryi Franch. =D. anthriscifolium
Hance var. calleryi (Franch.) Finet et Gagnep. ( =D. anthriscifolium Hance var.
anthriscifolium), Thalictrum thibeticum Franch. (= T. delavayi Franch. ), and C.
apiifolia DC.  var.  obtusidentata  Rhed.  et  Wils. (=C.  apiifolia  DC.  var.
argentilucida (Lévl. et Van. ) W. T. Wang) are all reduced into synonymies.
Owing to that Thalictrum delavayi Franch. var. decorum Franch. is a famous
ornamental plant and according to Art. 14 of the International Code of Botanical
Nomenclature, Thalictrum delavayi Franch. (1886) is suggested to be conserved
against  the  earlier  name   Thalictrum  thibeticum  Franch. (  1885). (  3)
Aconitum episcopale Lévl., Thalictrum lecoyeri Franch. T. macrostigma Finet et
Gagnep. (= T. sino-rnacrostigma W. T. Wang), Clematis pterantha Dunn, C.
tangutica (Maxin.) Korsh. var. obtusiuscula Rehd. et Wils., and Adonis davidii
Franch.,  which were put into synonymies by various authors, are restored. (4)
The infraspecific taxa of Thalictrum delavayi Franch. are reviewed and the revised
diagnosis for each taxon is given. The affinities between the species of the Clematis
acuminata group are discussed. A key to the species of ser. Acutangulae is given.
(5) one series, three species, three varieties, and two forms are described as new.
One new combination, and four new ranks are made, and one new name is
given. (6) The foreign distribution of Aconitum hemsleyanum Pritz. var. circinatum
W. T. Wang, Asteropyrum pehatum (Oliv.) Drumm. et Hutch., and Thalictrum
alpinum L. var. elatum Ulbr., which were formerly known endemic to China, is
reported.
