Abstract. A new name in Peucedanum, a new variety of Ostericum scaberulum, and four new combinations in Meeboldia, Hydrocotyle, and Oenanthe are proposed. They are: Peucedanum franchetii C. Y. Wu & Pu, Ostericum scaberulum (Franchet) Yuan & Shan var. longiinvolucellatum C. Y. Wu & Pu, Meeboldia yunnanensis (H. Wolff) Constance & Pu, Hydrocotyle burmanica Kurz subsp. craibii (H. Eichler) C. Y. Wu & Pu, Oenanthe javanica (Blume) DC. subsp. rosthornii (Diels) Pu, and Oenanthe thomsonii C. B. Clarke subsp. stenophyllum (Boissieu) Pu.

The nomenclature of several taxa of various genera of Apiaceae (Umbelliferae) needs adjustment. The nomenclatural changes are herein proposed to make the names available for the forthcoming volume 14 of the Flora of China.

Ostericum scaberulum (Franchet) Yuan & Shan var. longiinvolucellatum C. Y. Wu & Pu, var. nov. TYPE: China. Yunnan: Degen, Baima Snow Mount, among shrubs, Sep. 1935, C. W. Wang 69408 (holotype, KUN).

A varietate scaberulo differt involucellorum phyllis umbellulis longioribus et latioribus ca. 1 mm latis.

Variety longiinvolucellatum differs from variety scaberulum in having bractlets ca. 1 mm broad and longer than the fruiting umbellets. Variety scaberulum has bractlets ca. 0.5 mm broad and shorter than the pedicels and fruiting umbellets. The name longiinvolucellatum was first proposed as a nomen nudum in Wang (1993).

Paratypes. CHINA. Yunnan: Zongdian, 2780 m, with grasses and other herbs, 3 Aug. 1962, Likiang Bot. Gard. 100752 (KUN), Degong meadows, 3300 m, in shrubs, 3 Sep. 1959, K. M. Feng 23510 (KUN).

Peucedanum franchetii C. Y. Wu & Pu, nom. nov. Basionym: Peucedanum heterophyllum Franchet, Bull. Soc. Philom. Paris, ser. 8, 6: 141. 1894, not Visiani, Cat. Sem. Hort. Patav. 4. 1836. TYPE: China. Yunnan: Likiang, 3000 m, Oct. 1884, Delavay 192 (holotype, P).

Peucedanum franchetii is proposed to replace P. heterophyllum Franchet, which is a later homonym of P. heterophyllum Visiani.

Meeboldia yunnanensis (H. Wolff) Constance & Pu, comb. nov. Basionym: Sinodielsia yunnanensis H. Wolff, Notizbl. Bot. Gart. Berlin-Dahlem 9: 278. 1925. TYPE: China. Yunnan: Yunnan-fu, Cavalerie 42? (holotype, B).

Meeboldia (Wolff, 1924) and Sinodielsia (Wolff, 1925) share the same principal generic characters: strongly developed calyx teeth, narrowly ovoid fruit attenuate toward style and slightly constricted at the commissure, 2 or 3 vittae in each furrow and 4 on the commissure, sulcate seed face, 3- or 4-pinnatisect leaves, 5--10 rays that are 4--5 cm long, and an involucel of 5--7 linear-lanceolate bractlets. On the basis of their morphological similarities and geographical distribution in the Himalayas and southwestern China, it is concluded that Sinodielsia should be reduced to synonymy of the earlier published Meeboldia.

Hydrocotyle burmanica Kurz subsp. craibii (H. Eichler) C. Y. Wu & Pu, comb. nov. Basionym: Hydrocotyle craibii H. Eichler, Feddes Repert. 98: 146. 1987. New name for Hydrocotyle chinensis L. 1753, not H. shanii Boufford, Acta Phytotax. Sin. 28: 331. 1990, superfluous name. TYPE: China. Yunnan: Mengzi, woods, 8500 ft., A. Henry 10224 (holotype, K).

Subspecies craibii differs from subspecies burmanica in having orbicular-reniform, 5--7-lobed leaves. Both subspecies show a south to north trend from shallowly to deeply lobed leaves.

Hydrocotyle craibii H. Eichler and H. shanii Boufford (see Eichler, 1987; Boufford, 1990) were both proposed independently as new names for H. chinensis (Dunn ex R. H. Shan & Liou) Craib ex Tardieu-Blot, which is a later homonym of H. chinensis L. (1753).

Oenanthe javanica (Blume) DC. subsp. rosthornii (Diels) Pu, stat. nov. Basionym: Oenanthe rosthornii Diels, Bot. Jahrb. Syst. 29: 498. 1900. TYPE: China. Guizhou: Ping-fa, 21 Aug. 1902, J. Cavalerie 176 (neotype, E).

Oenanthe javanica subsp. rosthornii differs from subspecies javanica by its unequal rays, lanceolate involucel bractlets, and ovoid fruit. In subspecies javanica the rays are subequal, the involucel bractlets are linear, and the fruit is oblong.

Oenanthe thomsonii C. B. Clarke subsp. stenophyllum (Boissieu) Pu, stat. nov. Basionym: Oenanthe dielsii Boissieu var. stenophylla Boissieu, Bull. Acad. Int. Géogr. Bot. 16: 185. 1906. TYPE: China. Sichuan: Cheng kou, Farges s.n. (holotype, P; isotype, K).

Because of its homomorphic, finely 3- or 4-pinnate leaves, linear pinnae, and subglobose fruits, subspecies stenophyllum is more at home in Oenanthe thomsonii than in O. dielsii. Oenanthe dielsii has 1- or 2-pinnate hetermorphic leaves and linear, lanceolate, or rhomboid-ovate pinnae.
