| name = Ulmus 'Crispa Pendula' | genus = Ulmus | cultivar = 'Crispa Pendula' }} The elm cultivar Ulmus 'Crispa Pendula', the weeping fernleaf elm, was listed in the Gardeners' Chronicle & New Horticulturist (1873) as Ulmus crispa pendula, a variety of 'Crispa', itself described as "of the U. montana type".[1] 'Crispa Pendula' may be synonymous with the cultivar 'Adiantifolia', which appears from herbarium specimens to have a leaf similar to, but narrower than, 'Crispa'.[2] Green, however, treated 'Adiantifolia' as a synonym of 'Crispa'.[3] Description'Crispa Pendula' is similar to 'Crispa' but with narrower leaves and pendulous branches.[1] Pests and diseasesSee under 'Crispa'. CultivationThe tree was in cultivation at the Canterbury Nurseries, Kent, in 1873.[1] No specimens are known to survive, but it is possible that some surviving 'Crispa' are 'Crispa Pendula', as the latter cultivar is now unfamiliar, and as it is known that pendulous elms are marginally less likely to attract foraging Scolytus beetles.[4] References1. ^1 2 {{cite journal|title=Ornamental trees|journal=Gardeners Chronicle & New Horticulturist|date=25 October 1873|page=1433|url=https://books.google.co.uk/books?id=6Q8jAQAAMAAJ&pg=PA1433|accessdate=18 December 2017}} {{Elm species, varieties, hybrids, hybrid cultivars and species cultivars |state=collapsed}}2. ^{{Naturalis Biodiversity Center |id=WAG.1846722 }} 3. ^{{cite journal |last=Green |first=Peter Shaw |authorlink=Peter Shaw Green |date=1964 |title=Registration of cultivar names in Ulmus|url=https://archive.org/stream/arnoldiaarno_21#page/40/mode/2up/|journal=Arnoldia |volume=24|pages=41–80 |number=6–8 |publisher=Arnold Arboretum, Harvard University |access-date=16 February 2017}} 4. ^Webber, J.
