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 .
