Bark of the young twigs of a bright smooth green, scarred with rings at 

 the insertion of the leaves by the fall of the deciduous stipules. Leaves 

 alternate, stalked, regularly elliptical, entire, smooth. Their under side, 

 except the midrib, of a pale, glaucous colour. When young, covered with 

 a silken pubescence. Flowers solitary, terminal, on a short, incrassated 

 peduncle. Sepals three, spatulate, obtuse, concave. Petals 8 to 14, 

 obovate, obtuse, concave, contracted at their base. Stamens numerous 

 inserted in common with the petals on the sides of a conical receptacle; 

 filaments very short; anthers linear, mucronated, 2-celled, opening 

 inwardly. Ovaries collected into a cone, each divided by a furrow, and 

 tipt with a brownish, linear, recurved style. Fruit a cone, consisting of 

 imbricated cells, which open longitudinally at the back for the escape 

 of the seed. Seeds obovate, scarlet, connected to the cone by a 

 funiculus, which suspends them some time after they have fallen out. — 

 Bark bitter and aromatic, resembling and even rivalling in its qualities 

 cinchona. Particularly useful in chronic rheumatism. Tincture of 

 the bark, seeds, and cones, equally efficacious.
