Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae.[1] It is a large family, with 81 genera and about 2,625 known species.[2]
This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains. Some of the more commonly known members include pinks and carnations (Dianthus), and firepink and campions (Lychnis and Silene). Many species are grown as ornamental plants, and some species are widespread weeds. Most species grow in the Mediterranean and bordering regions of Europe and Asia. The number of genera and species in the Southern Hemisphere is rather small, although the family does contain Antarctic pearlwort (Colobanthus quitensis), the world's southernmost dicot, which is one of only two flowering plants found in Antarctica.[3]
Description
Despite its size and the somewhat doubtful mutual relationships, this family is rather uniform and easily recognizable.
Most are herbaceous annuals or perennials, dying off above ground each year. A few species are shrubs or small trees, such as some Acanthophyllum species.[4] Most plants are non-succulent; i.e. having no fleshy stems or leaves. The nodes on the stem are swollen. The leaves are almost always opposite,[5] rarely whorled. The blades are entire, petiolate, and often stipulate. These stipules are not sheath-forming.
The hermaphroditic flowers are terminal, blooming singly or branched or forked in cymes. The inflorescence is usually dichasial at least in the lower parts, which means that in the axil of each peduncle (primary flower stalk) of the terminal flower in the cyme, two new single-flower branches sprout up on each side of and below the first flower.[4] If the terminal flowers are absent, then this can lead to monochasia, i.e. a monoparous cyme with a single flower on each axis of the inflorescence. In the extreme, this leads to a single flower, such as in Githago or Arenaria.[4] The flowers are regular and mostly with five petals and five sepals, but sometimes with four petals.[5] The sepals may be free from one another or united. The petals may be entire, fringed or deeply cleft. The calyx may be cylindrically inflated, as in Silene. The stamens number five or 10 (or more rarely four or eight),[5] and are mostly isomerous with the perianth. The superior gynoecium has two to five carpels (members of a compound pistil) and is syncarpous; i.e. with these carpels united in a compound ovary. This ovary has one chamber inside the ovary. The fruit may be a utricle with a single seed or a capsule containing several seeds.[5]
Systematics
Currently, Amaranthaceae and Caryophyllaceae are sister groups and considered closely related.
Formerly, Caryophyllaceae were considered the sister family to all of the remaining members of the suborder Caryophyllineae because they have anthocyanins, and not betalain pigments. However, cladistic analyses indicate Caryophyllaceae evolved from ancestors that contained betalain, reinforcing betalain as an accurate synapomorphy of the suborder.[6]
This family is traditionally divided in three subfamilies:
- Alsinoideae: no stipules, petals not united
- Silenoideae: no stipules, petals united
- Paronychioideae: fleshy stipules, petals separate or united
The last, however, are a basal grade of rather primitive members of this family, not closely related, but simply retaining many plesiomorphic traits. Instead of a subfamily, most ought to be treated as genera incertae sedis, but Corrigiola and Telephium might warrant recognition as Corrigioleae. The Alsinoideae, on the other hand, seem to form two distinct clades, perhaps less some misplaced genera. Finally, the Silenoideae appear monophyletic at least for the most part, if some of the taxa misplaced in Alsinoideae are moved there; it may be that the name Caryophylloideae would apply for the revised delimitation.[7]
However, hybridization between many members of this family is rampant—particularly in the Silenoideae/Caryophylloideae—and some of the lineages of descent have been found to be highly complicated and do not readily yield to cladistic analysis.[8]
