This group has been established to include hybrids between Persea drymifolia (the Mexican race of horticulture) and P. americana (the Guatemalan and West Indian races). Fuerte is the only variety which at present falls within it, and even this is not definitely known to be a hybrid. It bears, however, many evidences of hybridity, and cannot rightly be classified either with the Mexican or the Guatemalan races.

Fuerte. - Form pyriform (not necked) to oblong; size below •medium to above medium, weight 10 to 16 ounces, length 4 to 4 1/2 inches, greatest breadth 2 1/2 to 2 7/8 inches; base pointed; the stem inserted obliquely in a small shallow cavity; apex obliquely flattened, depressed around the stigmatic point; surface pebbled, sometimes slightly wrinkled around the stem, dull green, with numerous small yellow dots; skin about 1/24 inch thick, separating readily from the flesh, pliable and leathery in texture; flesh rich cream yellow in color, greenish near the skin, of smooth buttery texture, and very rich flavor; quality excellent; seed small, tight in cavity, seed-coats closely surrounding cotyledons. Season January to August in southern California.

Originated at Atlixco, state of Puebla, Mexico; first propagated in 1911, in which year it was introduced into California. An unusual variety, apparently a hybrid between the Guatemalan race of Persea americana and the Mexican race (P. drymifolia). It is characterized by great vigor of growth, hardiness, good productiveness, and a long season of ripening differing from that of nearly all Guatemalan and Mexican varieties. The fruit contains as much as 30 per cent of fat, and is of very pleasant flavor.
