PARRY'S NUT PINE âPinus quadrifolia Parlatore This, the rarest of our nut pines, enters our area in southern Cahfomia, from Lower Cahfomia, where, in the mountains, it is very abundant. Its maximum height is 12 meters, with a trunk diameter of dm. It is also known as Parry's pinon, Nut pine. Parry's pine, and Mexican pinon. The branches are stout and spreading, forming a dense, regular cone, the lower branches frequently touch- ing the ground; very old trees are â ⢠»«»- more rounded and often irregular. The bark is about 16 mm. thick, shallowly fissured into flat ridges with few close scales or none on the dark reddish brown surface. The twigs are stout, short and softly hairy, soon becoming hght reddish brown. The leaves are in fascicles of 4, sometimes 3 to 5, the sheaths soon faUing away; they are pale glaucous green, stout, to cm. long, often 3 mm. wide, the dorsal faces usually the broadest, the tips thickened and short-pointed, en- tire-margined, marked on the lower surface by 4 to 10 conspicuous rows of stomata and contain 2 large dorsal resin-ducts and a single fibrovascular bun- dle ; they are,somewhat scattered on the twigs and persist more or less irregularly for three or four years. The staminate flowers are in spike-like clusters near the ends of the twigs; they are oval, about 5 mm. long; the involucre consists of four conspicuous, irregularly fringed bracts. The pistillate flowers are nearly terminal, usuaUy sohtary or few-clustered, almost sessile, subglobose, about 5 mm. long,
