New names of fossil Berberidaceae Author Doweld, Alexander B. text Phytotaxa 2018 2018-05-29 351 1 72 80 http://dx.doi.org/10.11646/phytotaxa.351.1.6 journal article 10.11646/phytotaxa.351.1.6 1179-3163 13687822 Alloberberis axelrodii Doweld , sp. nov. ≡ Mahonia sinuata Axelrod (1985: 193) , nom. inval . (Art. 40.1 of the ICN). Type :—[fossil leaves] 2 miles west of Fenwick ranch and about 7 miles south of Rockville, Malheur Co., Oregon , USA ( holotype , 17314, Museum of Palaeontology, University of Michigan , Ann Arbor, USA —illustrated by Arnold 1936 : pl. 2, figs. 3–4). Description :—Leaves with lanceolate to ovate leaflets having pinnate venation and obliquely cuneate bases; leaflets have 2–4 widely spaced, broad sinuses separated by lobes with sharp spines (after Axelrod 1985 ). Occurrence :—Miocene; North America ( USA ). Eponymy :—In honour of D. I. Axelrod (1910—1998), eminent American palaeobotanist. IFPNI :— 72DD25B8-5D3C-5B5F-AE85-6ED1335375C3 . Notes :—The fossil-species Mahonia sinuata Axelrod (1985: 193) was not validly published since the type was not designated (Art. 40.1 of the ICN). Axelrod (1985) related it to extant Mahonia eutriphylla Fedde (1901: 91) , a part of the formerly Mahonia section Horridae , recently segregated into a separate genus Alloberberis . Therefore, a new name is proposed for M. sinuata .
