Western Yew 123 cated scaly involucre; they have from 4 to 8 yellow stamens, their filaments short and stout; pollen-sacs 4 to 6, depressed and angular, opening tindemeath. The pistillate flowers are sessile, consisting of a solitary ovule partly surrounded by a low disk, and subtended by several imbricated scales; the disk enlarges greatly and becomes a persistent fleshy scarlet cup in fruit. The fruit ripens and falls off in the autumn; the seed, which is nut-like, is immersed in but free from the thick red gelatine-like cup-shaped disk; it is ovoid-oblong, sometimes slightly 3-ridged, narrowed and sharp-pointed at the apex, its base marked by an oval or triangular depression; the endosperm is abundant and fleshy, not channeled; cotyledons 2.

The genus is represented in America by 4 living species, a low shrub of the northeastern States, Taxus canadensis Marshall, called the American yew or Groimd hemlock; T. globosa Schlechtendal in Mexico; and the two following: Western tree; leaves 12 to 15 mm. long, yellow-green. Florida tree; leaves 20 to 25 mm. long, dark green. 1. T. brevijolia. 2. T. floridana. I. WESTERN YEW —Taxus brevifoUa Nuttall This beautiful evergreen tree or shrub occurs along streams and on slopes usually singly or few together, in the shade of the tall coniferous trees of the region, from British Columbia south to central Cahfomia, and extends east- ward to the Rocky Mountains, in Mon- tana and Idaho, reaching altitudes of 2400 meters. Its maximum height of 24 meters and trunk diameter of meters is attained in Oregon. It is also known as Pacific yew,. Mountain mahogany, and Yew. The trunk is tall and straight but often very irregu
