species in gardens, and spreads very rapidly by suckers. It is 
a handsome shrub or small tree with large hairy pinnate leaves 
and densely hairy thick shoots. Leaflets 9 to 25, glaucous 
beneath, sessile, lanceolate, acuminate, deeply serrate, the veins 
prominent below and as well as the main rachis clothed with 
fulvous hairs. Flowers greenish yellow or red, in dense

2, PISTACTA. 
Small trees or shrubs abounding in resinous secretions, with 
pinnate leaves, with or without a terminal leaflet, or sometimes 
trifoliolate, and small apetalous dicecious flowers in axillary 
ciusters. Fruit a dry 1-seeded drupe. There are about six 
species, from the Mediterranean region and Mexico. The name 
is an altered form of the Arabic appellation. The Mastich 
and Turpentine trees require protection in this country, but 
as they possess no ornamental features, they are rarely seen in 
any except botanic gardens. Several species furnish galls, 
employed in dyeing. 
P. Lentiscus. Mastich. A small tree with paripinnate 
evergreen leaves and a winged petiole. Anative of the shores 
of the Mediterranean Sea.—P. véra. Pistachio Nut. A de- 
ciduous-leaved species. Leaves composed of 2, 3, or 5 ovate

for its edible nuts.—P. Terebinthus. Turpentine Tree. Leaves
