var. veitchii (Wils.) Jesson

Synonyms
P. veitchii Wils.
P. glabra var. veitchii (Wils.) Hand.-Mazz.
P. fruticosa var. veitchii (Wils.) Bean

Leaflets hairy on both sides, as in var. mandshurica, but not so firm in texture and with the lateral veins prominent on the undersurface. The bractlets of the outer calyx are longer than in typical P. davurica and its Manchurian variety, about equalling the calyx in length. It is also more robust, growing to about 5 ft in height. The var. veitchii is a native of W. Hupeh, China, introduced by Wilson during his first expedition for Messrs Veitch, and was described by him, as a species, from a plant growing in Veitch’s nursery, raised from his seed-number 1087 (corresponding to specimen W.2187). It also occurs in W. Szechwan, but some of Wilson’s collections there, referred to the var. veitchii in Plantae Wilsonianae, seem to be less distinct from typical P. davurica.Cultivated plants have flowers about {1/4} in. wide, saucer-shaped when they first open; they are produced over a long period from later spring but never in great quantity, at least in the form available in commerce.Note. P. davurica Nestl. (or P. fruticosa var. davurica (Nestl.) Ser.) is the name that was accepted by all botanists for the species treated here, until Handel-Mazzetti pointed out, in 1940, that Nestler had described the flowers (from an herbarium specimen) as yellow, while in P. davurica as generally understood they are white. He adopted for this species the name P. glabra Lodd. It is a frequent source of difficulty in this group that the petals, whether originally yellow or white, usually turn eventually in herbarium specimens to a dingy yellowish colour. Nestler’s description, apart from the discrepancy over flower-colour, agrees perfectly well with the white-flowered species and his name is therefore retained here. It was published in the first half of 1816. The synonymous name P. glabrata Schlecht., also rejected by Handel-Mazzetti, was published some time in the same year, not in 1813 as stated in the Index Kewensis. It may be added that Maximowicz accepted plants with pale yellow flowers as part of the normal variation of the species.
