Not a large family, widely distributed in warm and tropical regions; ours are herbs or shrubs, with opposite or alternate, compound leaves, with stipules and toothless leaflets; flowers complete, usually with five sepals and five petals, and usually twice the number of stamens, with swinging anthers, alternate stamens sometimes longer, filaments often with a small scale near the middle; ovary superior, usually surrounded at the base by a disk; style one, with a five- to ten-lobed stigma; fruit dry.
There are several kinds of Covillea.

Southwest
A graceful, evergreen shrub, common in arid regions and a characteristic feature of the desert landscape, filling the air with its very strong, peculiar odor. It is from three to ten feet high, with many little branches, with blackish knots at the joints, clothed with sticky, dull yellowish-green foliage, the thickish, resinous leaflets very small, in pairs, with almost no leaf-stalk, and uneven at base. The pretty flowers are nearly an inch across, with bright yellow petals, with claws, and silky, greenish-yellow sepals which soon drop off. The filaments are broadened below into wings and have a scale on the inner side. The ovary is covered with pale, silky hairs, so that the older flowers have a silky tuft in the center, and becomes a round, densely hairy fruit, with a short stalk, tipped with the slender style. These little white, silky balls of down are very conspicuous and, as they are mingled with yellow flowers, the bush has an odd and pretty effect of being spotted all over with yellow and white.
Creosote-bush—Covillea glutinosa.
Crimson-beak—Krameria Grayi.
FLAX FAMILY. Linaceae.
A small family, widely distributed in temperate and tropical regions. Ours are smooth herbs, with loosely clustered, complete flowers, having five sepals; five petals, alternating with the sepals; five stamens, alternating with the petals, with swinging anthers and filaments united at the base; ovary superior; fruit a capsule, containing eight or ten, oily seeds.
There are many kinds of Flax, sometimes shrubby at base; with tough fibers in the bark; leaves without stipules, sometimes with glands at base in place of real stipules; flowers mostly blue or yellow. There are numerous, small-flowered, annual kinds, difficult to distinguish and usually somewhat local. L. usitatíssimum, an annual, with deep blue flowers, is the variety which, from time immemorial, has furnished the world with linen from its fiber and oil from its seeds. Linum is the ancient Latin name.
