Vegetative characteristics

Lomatium species are perennial herbaceous plants . All types are very long-lived; some specimens are known to be over 100 years old. Tap roots or deep-lying plant tubers are formed as persistence organs . The above-ground parts of the plant are hairy bald to woolly. In some species stems are not recognizable, in other species upright stems are simple or branched. At the base of the stem of some species there is a fibrous tuft of dead leaf sheaths .

The leaves are divided into leaf sheaths, petioles and leaf blades. The leaf blades are shaped very differently: simple and elongated, triangular-ovoid or obovate; one to multiple pinnate parts or one to multiple three-part composite. The leaf segments are shaped very differently.

There is no known toxic species of Lomatium .

Generative characteristics

There are distinct inflorescence stems. The flowers stand together in clearly double-gold inflorescences . Bracts are missing. The husk leaves are mostly present and conspicuous, rarely missing. The rays are spread out to upright and mostly winged at their base.

The flowers predominantly hermaphroditic and five-fold. Calyx teeth are missing. The five free, white, yellow or purple-colored petals are wide and narrow towards the top. There are five stamens . The two-chamber ovary is subordinate. There are two scars.

There are Doppelachänen formed. The linear to obovate individual fruits are flattened from the front to the back. The main ribs on the edge of the flat split fruit are broad to narrow, thin or thick winged or sometimes thread-like. The main ribs on the back protrude clearly. There are one or more oil streaks per rib interval. The fruit holder is free and split down to the bottom or there is a corky bar along the middle of the individual fruit. The seeds are flat to concave.

Systematics and distribution

Taxonomy

The genus Lomatium was established in 1819 by Constantine S. Rafinesque-Schmaltz in Journal de Physique, de Chimie, d'Histoire Naturelle et des Arts , Volume 89, Page 101. Type species is Lomatium villosum Raf. The generic name Lomatium is derived from the Greek and refers to the fact that the fruit is surrounded by a distinct wing. Synonyms for Lomatium Raf. are: Cogswellia Spreng. , Cusickia M.E.Jones , Cynomarathrum Nutt. , Euryptera Nutt. ex Torr. & A. Gray , Leibergia J.M. Coult. & Rose , Leptotaenia Nutt. ex Torr. & A.Gray .

There are three important monographs on the genus Lomatium : Mildred E. Mathias : A revision of the genus Lomatium. In: Annals of the Missouri Botanical Garden , Volume 25, 1937/8, pp. 225-297; John Merle Coulter , Joseph Nelson Rose : Umbelliferae In: Contributions from the United States National Herbarium , Volume 7, 1, 1900; Mark Schlessman: Systematics of Tuberous Lomatiums. In: Systematic Botany Monographs , Volume 4, 1984.

External systematics and botanical history

The genus Lomatium belongs to the tribe Selineae in the subfamily Apioideae within the family Apiaceae . The North American species of Peucedanum sl are, for example, in Lomatium Raf. or Cymopterus Raf. been outsourced. To the genus Orogenia S.Wats. only two species remain, the third species was added to Lomatium in 2017 .

Species and their distribution

The Lomatium species are mainly found in North America. Few species are also found in Mexico. Neither species is considered an invasive plant .

Many species of Lomatium occur only in a small area. 13 species were first described between 1973 and 2016. In 2017, Feist et al. some new combinations. In 2018 and 2019, new species were described and the rank of taxa changed.

The Lomatium species are genetically clearly defined, no transitions are known. There are no known hybrids in the genus Lomatium .

Kinship groups are discussed, which are referred to as complex. For example Lomatium grayi complex or Lomatium brevifolium complex.

use

Use as food

From some Lomatium TYPES (eg Lomatium ambiguum , Lomatium canbyi , Lomatium cous , dissectum Lomatium , Lomatium eurycarpum , Lomatium farinosum , Lomatium foeniculaceum , Lomatium Gayéri , gormanii Lomatium , grayi Lomatium , Lomatium macrocarpum , nudicaule Lomatium , triternatum Lomatium , Lomatium utriculatum ) were Parts of plants eaten by some tribes of the North American indigenous peoples :

For some North American tribes, Lomatium ambiguum has been a staple food and is one of the two most versatile types of Lomatium . The underground parts of the plant were eaten raw or cooked. The underground plant parts can also be dried and ground; You can use this powder to flavor soups, for example. The seeds can be ground or eaten raw. The inflorescences and the upper leaves can be used to season salads or soups etc.

Lomatium macrocarpum has been a staple diet for some North American tribes and is one of the two most versatile types of Lomatium . The underground plant parts were mostly peeled before cooking or eating. The dried underground plant parts can be ground and used to bake cakes. The seeds are eaten raw or cooked and are very nutritious. The ground seeds are used as a spice when baking bread or, for example, to flavor soups. Although the seeds are relatively small, they are still easy to harvest. The leaves, stems and flowers can be used to make tea.

Use as a medicinal plant

The medicinal effects of some Lomatium species (for example Lomatium ambiguum , Lomatium dissectum , Lomatium macrocarpum , Lomatium nudicaule , Lomatium triternatum , Lomatium utriculatum ) were investigated. They have already been used in folk medicine .
