saxifrage

(săk`sĭfrĭj), common name for several members of the Saxifragaceae, a family of widely varying herbs, shrubs, and small trees of cosmopolitan distribution. They are found especially in north temperate zones and include many arctic and alpine species. Most American species are native to the West. The true saxifrages (genus Saxifraga and some species of other genera), also called rockfoils, comprise a large group of low rock plants including several species cultivated as rock-garden and border plants—e.g., the strawberry geranium (S. sarmentosa) native to E Asia, which propagates by runners like the strawberry. Among American wildflowers are the Eastern early saxifrage (S. virginiensis) and a Western species called umbrella plant (S. peltata). The genus also includes the arctic and alpine S. oppositifolia, one of the northernmost (found on Ellesmere Island, for instance) of flowering plants. In the old doctrine of botanical naming, the saxifrage [Lat.,=rock-breaker], because of its apparent ability to split rocks in rooting, was prescribed medicinally for calculous formations, such as gallstones. Other American wildflowers of the family include the miterwort, or bishop's cap (genus Mitella), named for its cap-shaped fruit capsule; the false miterwort, or foamflower (Tiarella); the grass-of-Parnassus (Parnassia palustris) of swamps and moist meadowlands; and the alumroot (genus Heuchera). H. sanguinea, called coral-bells, is a delicate ornamental with bright red flowers, native to New Mexico and Arizona. The other wildflowers of this group grow chiefly in rich woodland areas of the Northeast and the far West. The mock orange, or syringa, is a genus (Philadelphus) of deciduous shrubs native to Eurasia and North America. It is easily cultivated and has white blossoms generally similar to orange blossoms. One of the most popular fragrant species is the common, or sweet, mock orange (P. coronarius). Syringa [New Lat., from Gr.,=pipe], an early name for mock orange, is now the scientific name for the unrelated lilac; both bushes are also sometimes called pipe tree. Among other shrubs of the saxifrage family cultivated as ornamentals are the deutzia, any species of the Asian genus Deutzia; and the hydrangea, American and Asian plants of the genus Hydrangea with flat-topped clusters of white, pink, or blue flowers. (The blue flowers are sometimes obtained by putting alum or iron in the soil.) Of minor economic importance is the genus Ribes, a group of berry-bearing shrubs, yielding the gooseberry and the currantcurrant,
northern shrub of the family Saxifragaceae (saxifrage family), of the same genus (Ribes) as the gooseberry bush. The tart berries of the currant may be black, white, or red; the white gooseberry becomes purple when mature.

, to name a few. Some botanists divide the family into three smaller families but all share common features. The Saxifragaceae are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).
