Wikipediadml Tiarella cordifolia 설명

 

 

Tiarella cordifolia, the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae.[3] The specific name cordifolia means "with heart-shaped leaves",[4] a characteristic shared by all taxa of Tiarella in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort.

 

Historically, the name Tiarella cordifolia has referred to the one and only species of Tiarella in eastern North America, but in 2021, the species was split into multiple taxa, which caused the name to have a different meaning. For clarity, the qualified name Tiarella cordifolia sensu stricto (abbreviated s.s.) refers to the new taxon while Tiarella cordifolia sensu lato refers to the old taxon.

 

Tiarella cordifolia sensu lato is wide-ranging across eastern North America while Tiarella cordifolia sensu stricto is narrowly confined to the East Coast of the United States. Cultivars of Tiarella are valued in horticulture for their erect stems of foamy cream-colored flowers.

 

Description

 

Inflorescence

Tiarella cordifolia sensu lato is a herbaceous, perennial plant with a scaly horizontal rhizome. The heart-shaped basal leaves have hairy stalks up to 20 cm (8 in) long. Both sides of the leaf blade have uniformly scattered hairs. The erect flowering stem is 15–40 cm (6–16 in) long, with a terminal raceme of 15–50 flowers. The flowers are white, small and feathery, giving the flower cluster a fuzzy appearance. Each flower has 5 sepals, 5 petals, and 10 long, slender stamens (which are longer than the petals). The two unequal seed capsules split along their inside seams, releasing several pitted seeds.[3][5]

 

Some species of Tiarella produce leafy stolons (T. austrina, T. stolonifera) and some have stem leaves (T. nautila, T. austrina). Some species have relatively large basal leaves with an extended terminal lobe (T. austrina, T. nautila, T. wherryi). Tiarella cordifolia sensu stricto has none of these characteristics.[6]

 

The heart-shaped basal leaves of Tiarella cordifolia sensu lato resemble those of species in other genera. For example, Tiarella is sometimes confused with Mitella diphylla, a closely related species that occurs over a similar range and habitat.[7][8] If a plant lacks sufficient evidence of flowering, the orientation of the hairs on the basal leaf stalk may be used to distinguish the two species.[9] All species of Tiarella in eastern North America have dense spreading hairs (outward-facing, angled 90 degrees) of various lengths while M. diphylla has long retrorse hairs (backward-facing, angled 45 degrees or less) sparsely distributed along its basal leaf stalk.[10]

 

Identification

To positively identify Tiarella cordifolia sensu stricto, all of the following key features must be verified (in any order):[11][12]

 

Stolon always absent

Basal leaves usually about as long as wide

Basal leaf lobes usually obtuse to rounded with the terminal lobe not extended

Flowering stem without leaves or foliaceous bracts
