Martynia
Martynia is a monotypic genus in the Martyniaceae family consisting of a single species, Martynia annua L., which is commonly known as cat's claw, tiger's claw, or iceplant. However, the name 'iceplant' may also refer to members of the unrelated plant family Aizoaceae. It is native to Mexico, Central America and the Caribbean, and has been introduced throughout the tropics. It is now quite common in rural areas of India. "Martynia" is used for making beads and ornaments, and has a history of folk medicine uses in the Indian subcontinent. Description. "Martynia" is an erect, somewhat shrubby  annual plant about tall, covered with glandular hairs, and has ovate, mucilaginous leaves wide and long. The leaves are opposite, and have red petioles. They resemble sticky rhubarb. Its flowers are pale pink and tubular, and have nectar guides and purple spots. Fruits become blackened when ripe and have hooked spines at the tip, lending its name "cat's claw" or "tiger's claw". They stick to animal fur and eventually the seeds fall out as the fruit gets crushed by the animal's feet. Taxonomy. The genus and species were first described by Carl Linnaeus in his 1753 publication , "Species Plantarum", although the modern taxonomic definition may not correspond with the original Linnaeus description, instead being a synonym for "Proboscidea louisianica" (Miller) Thellung, as well as other names used in India. "Martynia" was collected by the Scottish naval surgeon William Houstoun near Veracruz, Mexico. Houstoun sent seeds of this new plant to Philip Miller, chief gardener at the Chelsea Physic Garden, in 1731. Houstoun named the plant, "Martynia", in honor of a professor of botany at Cambridge, John Martyn. The plant was described in Martyn's work "Historia Plantarum Rariorum", with a full description and illustration. Martyn gave the  species the following descriptive name: "Martynia annua villosa et viscosa, folio subrotundo, flore magno rubro". In India, it has several taxonomic synonyms and common names. Distribution. "Martynia" is widely naturalized across subtropical and tropical world regions, particularly in Central America and the Indian subcontinent. It is typically found in uncultivated fields and arable lands from plains to . Uses. The plant is used for making beads and other native ornaments. It has been applied for numerous supposed treatments in Ayurveda and Siddha folk medicine.
