Hophornbeam (I giggle every time I say that for some reason) is one of many trees to go by the name of Iron wood. Since an earlier post by me stating that Osage can sometimes be called ironwood (old timers around my area), I did a little research (not much, mind you). Thought it to be somewhat interesting. From Wikipedia:
Ironwood may refer to the following:
Any particular wood that has a reputation for hardness. Usage of the name may (or may not) include the tree that yields this wood. Species involved include:
Androstachys johnsonii — Lebombo ironwood
Carpinus caroliniana — also known as American hornbeam
Casuarina equisetifolia — Common Ironwood from Australia
Choricarpia subargentea
Copaifera spp.
Eusideroxylon zwageri
Guaiacum officinale and Guaiacum sanctum — Lignum vitae
Hopea odorata
Krugiodendron ferreum — Black Ironwood
Lyonothamnus lyonii (L. floribundus) — Catalina Ironwood
Mesua ferrea — also known as Rose Chestnut or Ceylon Ironwood, from Thailand, Laos, Vietnam, Cambodia
Olea spp. — various olive trees
Olneya tesota — Desert Ironwood (of Subfamilay Faboideae, in Family Fabaceae)
Ostrya virginiana — Hop hornbeam
Parrotia persica — Persian Ironwood

That is all. You may return to your regularly scheduled program.
