. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. 244 The Hop Hornbeams or, at its northern range, in early June. The clustered staminate catkins are 3 to 8 cm. long, their scales triangular-ovate and long-pointed. The ripe pistillate hop-like catkins (strobiles) are oblong, 7 cm. long or less, stalked, the bladder-like bracts 12 to 16 mm. long, pointed, hairy, long-hairy near the base, finely netted- veined; the nut is 5 to 8 mm. long. The tree is of rather rapid growth and weU adapted to lawn and park planting. The wood is very strong and tough, close-grained, hard, light reddish brown, with a specific gravity of about 0.83; it is used for tool-handles, mallets, levers, and fence-posts. 2. KNOWLTON'S HOP HORNBEAM —Ostrya Knowltoni CoviUe This is one of the most locally distributed of all trees, being only known to occur in the Grand canon of the Colorado River in Arizona, where it is plentiful at a few places. Trees 10 meters high have been observed with trunks about 4.5 dm. in diameter near the base; the main trunk is usually very short and divides a little above the ground into several stout, nearly up- right branches, the smaller branches being very irregular and drooping. The outer bark is gray and peels off into long thin plates, the inner bark orange-brown. The young twigs are green and very hairy, be- coming smooth, brown, and ultimately light gray. The leaves are small, 5 cm. long or less, ovate to oval or obovate, blunt or short-pointed, sharply doubly toothed, rounded or shghtly heart-shaped at the base, finely hairy on both sides, rather dark green above, paler beneath; the very hairy leaf-stalks are 2 to 6 mm. long. The flowers appear in May. The staminate catkins are 2 to 3 cm. long, their scales broadly ovate and rather abruptly pointed. The ripe pistillate catkins are about 3 cm. long, stalked, with fewer bladder-Kke bracts
