This northeastern shrub of boggy glades and woods extends south at high elevation into W.Va., but it is virtually unknown south of the Great Lakes region and west of the Alleghenies. There is a coll. from central Ohio (OS) and a remarkable coll. by C.W. Short in 1840 at NY. Unfortunately, there are no locality data on Short's label, except for "Kentucky". However, thanks to M. Brock (pers. comm.) we can probably be confident that this coll. is linked with Short's (1840) paper, which histed "Ilex canadensis" from "wetlands of Henderson County." Although this Short coll. was known to Ky. botanists, it had not been considered a real record from the state; and M had suggested that the published record referred to I. decidua. Although probably gone from Ky. today, this southern disjunct locality is a remarkable matter for further investigation in the field and herbarium. Other disjunct northern plants have been recorded from HEND or elsewhere along the lower Ohio Rv. bottomlands, including Lathyrus ochroleucus, Micranthes pensylvanica, Spiraea alba and Stachys aspera. The genus Nemopanthus (perhaps monotypic) is now generally combined with deciduous species of Ilex; it "has free petals, stamens distinct from the petals and the calyx lobes are deciduous or semi-persistent in fruit; [but] some Ilex species also share these characters" (Powell et al. 2000). Nemopanthus also differs in having entire leaf margins or nearly so (versus serrated).
