(SPEC) Iris atropurpurea var. atrofusca Baker

1894, Baker Iris albopurpurea

Iris atropurpurea variety atrofusca (John Gilbert Baker, 1894) Considered at times to be a separate species; Iris atrofusca and as only a variety of Iris atropurpurea by Baker in Curtis's Botanical Magazine, table 7379, 1894 with these comments; "I. atrofusca, Baker in Gard. Chron. 1893, vol. i. p. 384. A full account of the Irises of the subgenus Oncocyclus, by Professor Michael Foster, with directions for their cultivation, appeared lately in the Garden (1893, vol. i. p. 130). They all inhabit Palestine, Syria, and Asia Minor, and require less humidity and more sunshine than we can give them in England, and in their native homes die down to the rootstock and remain at rest for a large part of the year. As above cited, I described the present plant in 1893 as a species, from specimens procured from the east of the Jordan by Messrs. Herb and Wulle of Naples. Now after studying fuller material I look upon it as a variety of atropurpurea. Baker, which was first imported in 1889 from Palestine by Messrs. Dammann and Co. Our plate was drawn from specimens flowered in Gloucestershire in April, 1894, by H. J. Elwes, Esq.

Descr. Rootstock thick, fleshy, cylindrical. Leaves about six to a stem, ensiform, weak, pale green, the outer sometimes a foot long at the flowering season. Peduncle one-flowered, a foot long, nearly hidden by the sheathing inner leaves. Spathe-valves lanceolate, pale green, ventricose three or four inches long ; pedicel very short. Perianth-tube cylindrical, green, two or two and a half inches long ; limb dark brown; outer segments obovate-cuneate, reflexed, three inches long by half as broad, with a velvety cushion of hairs spread all over the claw ; inner segments erect, obovate, unguiculate, longer and broader than the inner. Style-branches paler brown, very convex; appendages large, quadrate, reflexed. Anthers large, linear white. Capsule and seeds not seen.—J. G. Baker
