Mature foliage consists of phyllodes, which may be straight or falcate, acute or sub-falcate,
Pinnules oblong, often slightly falcate, entire or toothed.
Pinnæ broadly lanceolate-falcate or the lowest triangular, strongly auricled on the upper side, densely spinulose-toothed.
Thus, in Pl. 17, fig. 1, it is greatly developed and resembles a large horn with a falcate tip.
The two species known as Foxtail Pines are alike in their short entire falcate leaves, persisting for many years and forming long dense foliage-masses.
-- Body cylindrical, tapering to the tail; dorsal fin high, falcate, and placed about the middle of the body proper, excluding the tail portion; the forehead with a prominent boss over the snout, which is short; pectoral fins long and narrow; colour uniform leaden black, paler beneath.
The back fin rises behind the centre of the back; it is comparatively small, falcate, curved over the top to a blunt point, and concave behind.
"Muzzle pointed; eyes prominent; ears rather large, sub-naked; fur soft (rarely mixed with spines); pollex rudimentary; claws short; tail moderate or long, scaly, with scattered hairs; no cheek pouches; skull elongate, narrow; temporal ridges nearly parallel; palate compressed; incisive foramina long; auditory bullae moderately large; coronoid process high, falcate; incisors rarely grooved; molars with transverse ridges, each composed in youth of three tubercles" (_Alston_).

-- This differs from the last in a "rather smaller, lower, and more falcate dorsal fin, its more pointed and less anteriorly bulging head, and rather shorter and broader pectoral fins"
