FAMILY INDEX

FAMILY CODE: SAXIFR
FAMILY SCIENTIFIC: Saxifragaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Saxifrage Family
FAMILY SUMMARY: If narrowly circumscribed (as here), a family of about 35 genera and 500-650 species, herbs (mianly perennial), nearly cosmopolitan, but especially diverse in warm temperate and cold temperate regions of North America and Eurasia. The circumscription of a much narrower Saxifragacaeae is clearly warranted, based on a wide variety of data, and strongly corroborated by molecular data (Morgan & Soltis 1993 and many later references).

NCBG DESCRIPTIVES

INTRO: Rosette-forming, colonial perennial of moist forests, cove forests, rock outcrops and well-drained bottomland forests.
STEMS: Flowering stems unbranched, hairy.
LEAVES: Leaves basal, long-petiolate, broadly oval to nearly round, to 5 in. long, 3-7 lobed, palmately veined and sometimes mottled pale green or brown, toothed, hairy above; leaves evergreen in areas with mild winters.
INFLORESCENCE:
FLOWERS: Flowers in a crowded, glandular-hairy, terminal raceme that elongates and loosens with age, opening from bottom upward; white to pinkish-white (buds pink); about 1/3 in. wide; consisting of 5 spreading, pointed petals with basal claws, 10 long stamens and a conical ovary.
FRUITS: Fruit a conical capsule.
COMMENTS: Spreads by runners to form small colonies. Native Americans once made a tea out of foamflower leaves to use as a diuretic and to treat sore eyes.
HEIGHT: 10-12 in.

HORTICULTURAL
Plant Sale Text: This perennial grows in rich wooded areas of the mountains and piedmont, spreading by runners to form small colonies. Its leaves are similar to those of the red maple and have hairs on the upper surface. Foamflower blooms April through June, producing a six-inch stalk topped by delicate white flowers. Because the stamens protrude beyond the petals, the flower resembles a crown or “little tiara”, as the Greek word tiarella describes.

WEAKLEY FLORA

SCIENTIFIC NAME: Tiarella cordifolia
COMMON NAME:
SYNONYMY: [= FNA, Pa, S, W; > T. cordifolia var. cordifolia - C, G, K, RAB; > T. cordifolia Linnaeus var. collina Wherry - C, G, K, RAB; > T. cordifolia - F, V, WV, Z; > T. wherryi Lakela - F, V, Z; > T. cordifolia var. austrina - K, X, Y; > T. macrophylla Small - S (type a combination of Heuchera and Tiarella); > T. wherryi - X, Y; > T. cordifolia var. typica - Y; > T. cordifolia var. collina - X]
PHENOLOGY: Apr-Jun.
HABITAT: Moist forests, cove forests, rock outcrops, well-drained bottomland forests.
COMMENTS: NS west to ON and WI, south to w. NC, nw. SC, sw. GA, AL, MS, and MO. Several taxa have been recognized (or not) in eastern North American Tiarella. The characters used to recognize additional species or varieties are often missing on herbarium sheets and also seem to be imperfectly correlated. T. wherryi (or var. collina) is alleged to differ from T. cordifolia s.s. in lacking stolons (vs. having stolons), capsules 6-10 mm long and round-tipped (vs. 8-12 mm long and subacuminate), and lower fruiting pedicels 6-10 mm long (vs. 7-13 mm long). Additional taxa have sometimes been recognized; see Lakela (1937), Wherry (1940, 1949), Fernald (1943), and Spongberg (1972) for discussion. Further study is needed; for now, I have opted (without great confidence) for a broad approach.
