Ostrya virginiàna (Miller) Willdenow. Ironwood. [Plate 31.] Small trees up to 5 dm.[28] in diameter, usually about 1-2 dm. in diameter; bark smooth and light brown on small trees, shreddy on older trees; shoots hairy, becoming at the end of the season glabrous or nearly so and a reddish-brown; leaves oblong-ovate, other forms rare, average size about 7-12 cm. long, acuminate, usually double-serrate, hairy on both surfaces when they unfold, glabrous or nearly so above at maturity, more or less pubescent beneath, especially on the midrib and veins; staminate spikes develop in early winter; fruit hop-like about 2-4 cm. long; nut oblong-ovate about 7 mm. long and half as wide, compressed, light brown; wood very hard, tough, close-grained, strong, light brown.

Distribution.—Nova Scotia west to Manitoba, south to the Gulf States and west to Texas. It is frequent to common in all of the counties of the State. However, it is entirely absent in the lower Wabash bottoms, except rarely on high grounds in this area. It prefers well drained dry soil, and is most frequent when it is associated with beech and sugar maple, although it is often quite plentiful in white oak woods. It is shade enduring and is one of the under trees in the forest where it grows very tall and slender and free from branches. When it grows in exposed places such as bluffs, it retains its side branches and is usually bushy.

Remarks.—The trees are too small to be of much economic importance. It is 30 per cent stronger than white oak, and 46 per cent more elastic. These exceptional qualities were recognized by the Indians and it was used by them where wood of great strength and hardness was desired. Likewise the pioneer used it where he could for handles, wooden wedges, etc. Since it grows neither large nor fast, it is usually regarded as a weed tree in the woodland, and should be removed to give place to more valuable species.

Ostrya virginiàna variety glandulòsa Spach. This is the name given to the form which has the twigs, petioles, peduncles and often the midrib and veins of the leaves beneath covered more or less with short erect, reddish, glandular hairs.

It is found with the species, but is not so frequent.
