Family Caryophyllaceae

Herbs annual or perennial , rarely subshrubs or shrubs . Stems and branches usually swollen at nodes. Leaves opposite, decussate, rarely alternate or verticillate , simple , entire, usually connate at base ; stipules scarious , bristly , or often absent. Inflorescence of cymes or cymose panicles, rarely flowers solitary or few in racemes , capitula, pseudoverticillasters, or umbels. Flowers actinomorphic , bisexual , rarely unisexual , occasionally cleistogamous . Sepals (4 or) 5, free , imbricate, or connate into a tube , leaflike or scarious, persistent , sometimes bracteate below calyx. Petals (4 or) 5, rarely absent, free, often comprising claw and limb; limb entire or split, usually with coronal scales at juncture of claw and limb. Stamens (2--) 5--10, in 1 or 2 series. Pistil 1; carpels 2--5, united into a compound ovary. Ovary superior, 1-loculed or basally imperfectly 2--5-loculed. Gynophore present or absent. Placentation free, central, rarely basal; ovules (1 or) few or numerous , campylotropous. Styles (1 or) 2--5, sometimes united at base. Fruit usually a capsule, with pericarp crustaceous , scarious, or papery , dehiscing by teeth or valves 1 or 2 × as many as styles, rarely berrylike with irregular dehiscence or an achene. Seeds 1 to numerous, reniform , ovoid , or rarely dorsiventrally compressed , abaxially grooved , blunt , or sharply pointed , rarely fimbriate-pectinate; testa granular , striate or tuberculate , rarely smooth or spongy ; embryo strongly curved and surrounding perisperm or straight but eccentric ; perisperm mealy.

Between 75 and 80 genera and ca. 2000 species: widespread but mainly of temperate or warm-temperate occurrence in the N hemisphere, with principal centers of distribution in the Mediterranean region and W Asia to W China and the Himalayas, fewer species in Africa S of the Sahara, America, and Oceania; 30 genera (two endemic) and 390 species (193 endemic) in China.

Arenaria, Silene, and Stellaria contain over half the species in the family in China. They are mostly concentrated in the Qinghai-Xizang plateau , and are especially rich from the Hengduan Mountains to the Himalayas. The main uses of this family are medicinal and ornamental . Dianthus superbus, Pseudostellaria heterophylla, Stellaria dichotoma var. lanceolata, and Vaccaria hispanica are commonly used in traditional Chinese medicine . Some species of Arenaria, Dianthus, Gypsophila, Psammosilene, and Silene are used as medicinal herbs among the people or are habitually used in local Chinese medicine. Many species of Dianthus, Gypsophila, Lychnis, Saponaria, and Silene are grown as ornamentals. Atocion armeria (Linnaeus) Rafinesque ( Silene armeria Linnaeus), native to Russia and Europe, is also cultivated in China. It differs from Silene in having a corymbose inflorescence and obscure calyx veins. Wu Cheng-yih, Ke Ping, Zhou Li-hua, Tang Chang-lin & Lu De-quan. 1996. Caryophyllaceae.

Capsules ovoid to globose , opening along sutures into 3-5 valves , frequently splitting into 6-10 equal teeth; carpophore usually present. Seeds ca. (5-) 15-100(-500+), reddish to gray or black, reniform to globose, usually tuberculate or papillate, papillae around margins sometimes larger and inflated, marginal wing sometimes present, appendage absent; embryo peripheral, curved . x = (10) 12.

Species ca. 700: mainly Northern Hemisphere.

Silene includes several important weeds and some very beautiful horticultural plants. In addition to the species described in this account, several others have occurred in the flora area as chance introductions or garden escapes , but they have not become established and most have not been seen recently. They include S. coeli-rosa (Linnaeus) Godron, S. cretica Linnaeus, S. (Lychnis) fulgens (Fischer) E. H. L. Krause, S. italica Persoon, and S. nutans Linnaeus.

In this account, Lychnis, Melandrium, and Viscaria have been included in Silene, their previous recognition as distinct genera having resulted in a great deal of confusion in both nomenclature and taxonomy. I have not presented an infrageneric classification of Silene because existing systems either do not include those other genera (e.g. , P. K . Chowdhuri 1957) or do not deal with most of our native North American taxa [e.g., W. Greuter (1995) and the molecular studies by Oxelman and coworkers (e.g., B . Oxelman et al. 1997, 2000]. The recent molecular study by J. G. Burleigh and T. P. Holtsford (2003) provides little support for existing morphologically based sectional classifications within Silene insofar as they relate to endemic North American taxa. However, it does indicate the distinctness of our arctic alpine species (S. involucrata€”as S. furcata, and S. acaulis) that are circumpolar in their distribution.[2]

Size/Age/Growth

Size: 12-18" tall.

Landscaping

Landscape Uses: Rock gardens. Wildflower gardens. Shade gardens. • Care: Tolerates coastal conditions.

Habitat

Biome: Terrestrial [3].

Ecology: A perennial herb which grows on the rocky slopes of small volcanic islets .

Silene hicesiae belongs to the "Silene mollissima group", which comprises seven species endemic to the coastal cliffs of the western Mediterranean basin . These different species may have evolved when the Mediterranean became drier during the late Miocene period, about 5 million years ago, and the ancestral species became isolated into several different populations. This is one of numerous examples demonstrating how geographic separation of populations belonging to the same species, for example on islands, can contribute to the formation of new species.

It grows in the Habitats Directive listed habitat 1240 "Vegetated sea cliffs of the Mediterranean coasts with endemic Limonium spp. " (Commission of the European Communities 2009). (Ref. 306819).
