Abstract:

The genus Notopterygium is endemic to China. The plants of this genus are important
traditional Chinese medicine. When established by H. de Boissieu in 1903, Notopterygium includ-
ed only two species, i.e.N. franchetii and N. forbesii. Within nearly a century, five more spe-
cific names had been added to this genus, i.e.N. forrestii H. Wolff, N. oviforme Shan, N. in-
cisum Ting ex H. T. Chang, N. pinnatiinvolucellatum Pu et Y. P. Wang, N. tenuifolium Sheh
et Pu. Based on field observation and examination of herbarium specimens, all the taxa in this genus
were taxonomically reviewed and their nomenclature was carefully checked. N. oviforme was treated
as a subspecies under N. forbesii. We agree with Chang He-Tseng in reducing N. franchetii to N.
forbesii as a synonym. As a result, five species, one of which contains a subspecies, are recog-
nized. Based on the morphology of involucel bractlets as well as their relevant characters, No-
topterygium is divided into two sections.
      Sect. 1. Notopterygium
      Basal and proximal cauline leaves 2-ternate to 2 ～3-ternate-pinnate, ultimate divisions broad-
ovate or ovate-lanceolate; involucel bractlets linear, entire, vascular bundles of petiole approximate-
ly equal in size. This section contains two species and one subspecies.
      Sect. 2. Tenuifolium Pu, sect. nov.
      Basal and proximal cauline leaves 2 ～3-ternate-pinnate, ultimate divisions linear-lanceolate,
ovate-lanceolate or linear; involucel bractlets linear, entire or oblanceolate, 2 ∽ 3-fid or pinnate at the apex; vascular bundles of petiole unequal in size. This section centains three species.
