North of Mexico. Volume 09: Magnoliophyta: Picramniaceae to Rosaceae. 2014. 1 col. pl. Many dot maps. XXIV, 713 p. 4to. Cloth.

Volume 9 includes four families - Picramniaceae (bitter-bush family), Staphyleaceae (bladdernut family), Crossosomataceae (crossosoma family), and Rosaceae (rose family). This volume contains treatments of nearly 700 species with over 98% of them being species of Rosaceae. Every genus has representative taxa illustrated to aid in plant identification and to demonstrate the morphological variation that exists for these families in North America. Many economically important plants with edible fruits are members of the Rosaceae, with both native and introduced species known and consumed by people: apples, pears, peaches,almonds, apricots, plums, cherries, strawberries, blackberries, and raspberries are probably the most commonly utilized. Other members of the Rosaceae, many of great horticultural interest worldwide, are also noteworthy in the North American flora, including roses, hawthorns, cinquefoils, firethorns, quinces, chokecherries, shadbushes, mountain ashes, and loquats.-Second hand copy.
