''Ulmus minor'' 'Propendens'

Ulmus minor 'Propendens'
'Propendens' (described here by its synonym, Ulmus campestris suberosa pendula)
Species Ulmus minor
Cultivar 'Propendens'
Origin Europe

The Field Elm cultivar Ulmus minor 'Propendens', described by Schneider in 1904 as U. glabra (:minor) var. suberosa propendens,[1][2] Weeping Cork-barked elm,[3] was said by Krüssmann (1976) to be synonymous with the U. suberosa pendula listed by Lavallée without description in 1877.[4] Earlier still, Loudon's Arboretum et Fruticetum Britannicum (Volume 7, 1854) had included an illustration of a pendulous "cork-barked field elm", U. campestris suberosa,[5] and an U. campestris suberosa pendula was distributed in Victoria from the 1870s.[6]

Krüssmann himself considered 'Propendens' a form of U. minor 'Suberosa', calling it U. carpinifolia 'Propendens'.[7] An U. campestris suberosa pendula was distributed by the Späth nursery of Berlin and by Smith's of Worcester from the 1880s.[8][9][10]

Green considered Kirchner's Ulmus rugosa pendula (1864)[11] a synonym of 'Propendens'.[2]

Description

'Propendens' has branches wide-spreading, nodding, and corky; the leaves are small, 2 cm (0.79 in)–3 cm (1.2 in) long.[12]

Pests and diseases

Most U. minor cultivars are susceptible to Dutch elm disease, but, if not grafted, can survive through root-sucker regrowth.

Cultivation

'Propendens' remains in cultivation in Belgium (see 'Nurseries'). No surviving mature specimens are known. Späth supplied an U. campestris suberosa pendula to the Dominion Arboretum, Ottawa, Canada in 1899,[13] and three to the Royal Botanic Garden Edinburgh in 1902, which may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[14] The current list of Living Accessions held in the Garden per se does not list the plant.[15] 1902 RBGE herbarium specimens, however, show smooth rather than corky twigs (see 'External links'). The 1896 Kew Gardens Hand List contained an U. campestris var. microphylla pendula which Rehder considered a synonym of 'Propendens'.[16] Henry (1913) described a 'Microphylla Pendula' at Kew Gardens, with small leaves about an inch in length, as "a form of Ulmus nitens var. suberosa", equating it with Schneider's 'Propendens'.[17] An Ulmus microphylla pendula, 'Weeping Small-leaved Elm', possibly 'Propendens', appeared in the 1904 catalogue of Frederick W. Kelsey, New York.[18] An U. suberosa pendula with "dark-green rough leaves" and "corky branches" appeared in the 1909 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey, where it was distinguished from U. campestris microphylla pendula.[19] A specimen obtained from Späth as U. suberosa pendula and planted in 1911 stood in the Ryston Hall arboretum, Norfolk,[20] in the early 20th century.[21] 'Propendens' is believed to have once been popular in eastern Europe.[22]
