Hesperònia glutinòsa var. grácilis
White, pinkish
Spring
Arizona

This has a straggling, hairy, sticky stem, over a foot long, and thickish, dull-green leaves, hairy and sticky. The flowers are about half an inch long, white or tinged with pink, and are rather delicate and pretty, though the plant is not especially attractive. It blooms at night, the flowers gradually closing with the morning sun. This variety is common in the southern part of the state, in mountain canyons, and Hesperonia glutinosa is common in the north.

There are several kinds of Abronia, all American, with branching, usually sticky-hairy stems, thick, toothless leaves, with leaf-stalks, in pairs and one of each pair somewhat larger than the other. The flowers are more or less salver-form, with five lobes, a threadlike style, and from three to five, unequal stamens, on the tube of the perianth and not protruding from it. They are numerous and in clusters, with involucres, on long flower-stalks, from the angles of the leaves. The fruit is winged. The name is from the Greek meaning graceful, but most of these plants are rather awkward in their manner of growth.

This plant is, as a whole, so delicately tinted and so decorative in form, that it is most attractive, particularly against the sandy soil where it grows, deserving the Greek name more than some of its slightly awkward sisters. It is about fourteen inches tall, with a stoutish, rather straggling, prostrate stem, which is pale, pinkish, sticky and fuzzy. The leaves have long leaf-stalks and are pale bluish-green, leathery and smooth, but fuzzy on the mid-vein of the under side, and the flowers are numerous, rather small, in handsome roundish clusters, which are about two inches across, with a papery, pinkish or yellowish involucre, of about five, separate, rounded bracts. The calyx is corolla-like and salver-form, with a long, yellowish or greenish tube and five lobes, prettily crinkled at the edges. The seed-vessel is very curious, resembling a round, yellowish sponge, with hooks sticking out of it, and the flowers are deliciously sweet-scented. This is sometimes called Snowball.

Pink Sand-Verbena
Abrònia villòsa
Pinkish-lilac
Summer
Ariz., Cal., Utah

The coloring of this plant, one of the prettiest of its kind, is striking and unusual, and makes it very conspicuous, growing in the sand near the sea or in the desert. The thickish leaves are light bluish-green and the thick stem, which straggles rather awkwardly over the ground, is a peculiar shade of pink and sticky and hairy, as are also the involucres. The small delicate flowers are an odd tint of pinkish-lilac, light but vivid, in striking contrast to the coloring of stems and foliage, and form very pretty clusters, with an involucre of five to fifteen papery bracts. They are very fragrant and look much like garden Verbenas, so the name is not so unhappy as some. A. umbellàta has slender stems and almost smooth leaves, sometimes with wavy margins, about an inch long, narrowed at base to a slender leaf-stalk, and deep-pink flowers. It is common all along the California coast and blooms in the summer and autumn. A. marítima is found from Santa Barbara to San Diego and is a very stout, coarse, sticky plant, with small, deep-magenta flowers.
