Viburnum deamii (Rehder) Sorrie. Indiana Arrow-wood. Phen: Jun-Aug; late Aug-Nov. Hab: Streamsides, floodplains, and swampy forests. Dist: S. OH, n. KY, west through s. IN and s. IL to ne. MO, primarily in the Ohio River Valley.

Origin/Endemic status: Endemic

Taxonomy Comments: V. deamii formerly was placed within V. dentatum as var. deamii (Rehder) Fernald. However, the presence of stipitate hairs on petioles and leaves, plus presence of leaf stipules, suggests a closer relationship to V. bracteatum than to V. dentatum, which lacks these features. Here we also include taxon "indianense", a glabrate form which appears to intergrade too freely with taxon "deamii" to warrant recognition. Most records are from north of the Ohio River, but also with specimens vouchered from Ballard, Campbell, Henderson, and Rowan counties, KY. See Sorrie (2012) for additional information.
