ABSTRACT. Three new combinations, Tournefortia sibirica L. var. angustior (A. DC.) G. L. Chu & M. G. Gilbert, Lappula ferganensis (Popov) Kamelin & G. L. Chu, and L. lasiocarpa (W. T. Wang) Kamelin & G. L. Chu, plus a new name, Trigonotis harrysmithii R. R. Mill, are validated.

Two precursory papers on the Boraginaceae for the Flora of China have already been published (Kamelin, 1993; Riedl, 1994). The following additional nomenclatural adjustments are herein proposed to make the names available for the forthcoming Volume 16 of the Flora of China.

Tournefortia sibirica L. var. angustior (A. DC.) G. L. Chu & M. G. Gilbert, comb. nov. basionym: Tournefortia arguzia Roemer & Schultes ß angustior A. DC., Prodr. 9: 514. 1845. SYNTYPES: China. Nei Mongol ("Chinese Mongolia"), Turczaninow s.n., Bunge s.n.; Kazakhstan. E shore of Caspian Sea, Karelin s.n. and Hohenacker s.n.; Russia. Astrakan, Bieberstein s.n.; Turkey ("Asia Minor ), Aucher-Éloy s.n.; Ukraine. S Podoliâ, Turczaninow s.n. (AN syntypes in G, not seen.)

The new combination is needed because the variety does not have a valid combination in Tournefortia sibirica. A lectotype should be designated from de Candolle's original material at G. Such material has not been examined by us.

Trigonotis harrysmithii R. R. Mill, nom. nov. Replaced name: Trigonotis smithii W. T. Wang, Bull. Bot. Res., Harbin 13(1): 3. 1993, not Trigonotis smithii Banerjee, Bull. Bot. Surv. India 8: 325. 1966 (1967). TYPE: China. Sichuan: Sungpan, 3200 m, 14 July 1922, Harry Smith 2775 (holotype, UPS; isotype, PE).

The earlier name Trigonotis smithii Banerjee, which applies to a species from Bhutan and the east Himalaya so far not recorded from China, was named after William Wright Smith, the collector of the type specimen and a former Regius Keeper of the Royal Botanic Garden, Edinburgh. The later homonym was dedicated to the Swedish botanist Harry Smith, an expert on the Gentianaceae who collected in China.

There has been a reappraisal of the characters dividing Lepechiniella from Lappula. Lappula is readily distinguished from Lepechiniella in having styles exserted from the nutlets instead of concealed by them. No Chinese material belongs to Lepechiniella as thus defined, which makes necessary the following generic transfers.

Lappula ferganensis (Popov) Kamelin & G. L. Chu, comb. nov. Basionym: Lepechiniella ferganensis Popov, Fl. USSR 19: 715. 1953. TYPE: [Tajikistan]. Alai Valley, Mount Kultzcha, 26 June 1931, Lipschitz 248 (holotype, MW).

Lappula platyptera C. J. Wang, Bull. Bot. Res., Harbin 1(4): 91. 1981, Syn. nov.

TYPE: China. Xinjiang: Wuqia Xian, 3300 m, 4 Aug. 1978, Xinjiang Expedition 1911 (holotype, WUK).

Lappula lasiocarpa (W. T. Wang) Kamelin & G. L. Chu, comb. nov. Basionym: Lepechiniella lasiocarpa W. T. Wang, Bull. Bot. Res., Harbin 4(2): 7. 1984. TYPE: China. Xinjiang: Fuhai, 21 May 1959, Y. F. Wang s.n. (holotype, PE).

Lepechiniella balchaschensis M. Popov, Spisok. Rast. Gerb. Fl. SSSR 12: 50. 1953. Syn. nov. Lappula betpakdalensis Nabiev, Opred. Rast. Sred. Azü 8: 138. 1986, not Lappula balchaschensis M. Popov ex N. Pavl., Zhurn. Bot. U.R.S.S. 30(4): 190. 1945. TYPE: Kazakhstan. Lake Balchasch, southern shore at Bertys Bay, 15 June 1934, M. Popov s.n. (holotype, LE).

Lepechiniella balchaschensis is the oldest name for this species, but the epithet is not available in Lappula because Popov had already described Lappula balchaschensis based on a different type. The transfer to Lappula was made in 1986 by Nabiev, who introduced the replacement epithet betpakdalensis. However, Lepechiniella lasiocarpa W. T. Wang is the older name that should be used in Lappula.
