There are several kinds of Sericotheca, much like Spiraea, except the fruits.
Ocean Spray
Sericothèca discolor (Spiraea) (Holodiscus)
White
Summer
Northwest and Southwest
A handsome conspicuous shrub, from three to eight feet high, without stipules, with roughish, dull-green leaves, toothed or lobed, but not with leaflets, and pale and woolly on the under side. The tiny flowers form beautiful, plumy, branching clusters, eight inches or more in length and almost as much across, cream-white and fuzzy, drooping and turning brownish as the flowers fade. This is common in the mountains.
There are numerous kinds of Rubus, in temperate regions, with white, pink, or purple flowers, and red, black, or yellowish "berries." The fruit is not really a berry, but a collection of many, tiny, round stone-fruits, crowded on a pulpy, conical receptacle. That of the Raspberry has a "bloom," and falls off the receptacle when ripe, but the Blackberry has shining, black fruit, which clings to the receptacle. Rubus, meaning "red," is the ancient Latin name for the bramble. Raspberries were cultivated by the Romans in the fourth century.
Salmon-berry
Rùbus spectàbilis
Red
Summer
Northwest
A handsome bush, not at all trailing, from three to nine feet high, with dark-brown, prickly stems, fine foliage and flowers, and conspicuously beautiful fruit. The leaves are nearly smooth, with three leaflets, and the flowers, about two inches across, are a brilliant shade of deep pink, not purplish in tone, with yellow centers, and grow singly, or two or three together. The fruit is a firm, smooth raspberry, over an inch long, bright orange-color, more or less tinted with red, with a rather pleasant but insipid taste and not very sweet. This grows in woods. It is rather confusing that this should be called Salmon-berry in the West, for in the East that is the common name of Rubus parviflorus.
Common Blackberry
Rùbus vitifòlius
White
Spring, summer
California, etc.
An evergreen bush, a few feet high and more or less erect; or the prickly stems trailing on the ground, or climbing over other shrubs, and sometimes eighteen feet long. The leaves are downy, or almost smooth, usually rather coarse in texture, and all but a few of the upper ones have from three to seven leaflets. The flowers are about an inch across and the petals vary a good deal, being sometimes broad and sometimes rather long and narrow. This is common from southern California to British Columbia.
Salmon-berry—R. spectabilis.
Common Blackberry—Rubus vitifolius.
