description
Vegetative characteristics
Talinum species are perennial herbaceous plants or rarely subshrubs . A bulbous "root stock" ( caudex ) is formed, which can be fleshy to woody. They upright shoot axes are simple or branched. Some plant species lose their aboveground plant parts during dormancy.
The alternate or almost opposite arranged and often irregularly spaced leaves are short stalked or almost sessile. The simple, entire leaf blades are very variable in shape, 1 to 7 centimeters wide and more or less succulent . True stipules are missing, but there are inconspicuous and small scales that fall off early.
Generative characteristics
The flowers stand individually in the leaf axils or are grouped in several in terminal paniculate inflorescences .
The hermaphroditic flowers are radial symmetry with a diameter of 0.3 to 1.5 cm . The flowers usually only open once for a short time or are cleistogamous . There are two sepals , which soon fall off or are rarely durable. The usually five, rarely up to seven petals are only fused or free at their base. The flower contains 10 to 30 stamens . Three fruit leaves are a top permanent, single-chamber ovary grown. The stylus is up to 3 mm long or absent.
The spherical to elongated fruits contain many black, spherical seeds .
Invasive Plants
The two species Talinum triangulare and Talinum paniculatum are considered invasive plants almost worldwide .
Systematics and distribution
The genus Talinum was 1763 Michel Adanson in Familles des Plantes , 2, page 245, and 609 installed . Talinum Juss is a homonym . nom. illegal. ( Genera Plantarum , 1789, 312). Synonyms for Talinum Adans. nom. cons. are: Helianthemoides medic. , Phemeranthus Raf. , Eutmon Raf. , Chromanthus Phil. , Litanum Nieuwland and Ketumbulia Ehrenberg .
The origin of the name of the genus is unclear, it was probably named after the common name of a species in Senegal or after the Latin word telinum , which stands for a valuable ointment made from fenugreek .
Botanical history
Often quoted when it comes to the genus Talinum is JN Rose, PC Standley: The genus Talinum in Mexico. in Contributions from the United States National Herbarium. Smithsonian Institution. , Volume 13, 1911, pp. 281-288. The genus Talinum was divided according to Roger Charles Carolin (* 1929) into two sections Talinum and Phemeranthus (Raf.) DC. VK Von Poellnitz published the monograph on the genus Talinum Adans in 1934 . in Repertorium Specierum Novarum Regni Vegetabilis. Centralblatt for the collection and publication of single diagnoses of new plants. , Volume 35, pp. 1-34. Until Kiger 2001 were in the genus Talinum s. l. contain up to 50 species.
The species of the Phemeranthus section have been in an independent genus Phemeranthus Raf since Kiger 2001 . and placed this in the family of the Montiaceae .
