Description and ecology

Illustration of the Green Milky Star ( Honorius boucheanus , Syn .: Ornithogalum boucheanum )

Habit and leaves

They are perennial herbaceous plants . They form almost all onions , rarely rhizomes, as persistence organs, which in these typical geophytes are mostly underground, but in some species of onions also occur above ground. The underground parts of the plant in particular contain slimy milky sap .

Most species of the Scilloideae prefer open, sunny locations with dry and hot growing seasons. Areas with significant dry seasons are home to many species. In the temperate areas they grow as spring geophytes in the deciduous deciduous forests. But there are also autumn-blooming species (for example the autumn squill Prospero autumnale ). Only a few species (for example Rhadamanthus urgineoides from Madagascar) grow epiphytically on trees in rainforests. There are hardly any species in the tropical lowlands. They are mostly seasonal green (for example only in the rainy season or only in spring) or less often evergreen.

Drawn leaves of Ledebouria socialis

The change-constant and usually spirally often arranged in rosettes undergraduate leaves are usually upright upwards, but in some species they lie flat on the ground. The simple, sessile leaves are parallel-veined, entire and often more or less lanceolate. Most of the hairless leaves are monochrome, but some species, especially Ledebouria , Lachenalia and Eucomis, are markedly dark green to purple in color . In some species of Lachenalia and Massonia the upper side of the leaf has warts, pustules or hairs. In a few species the leaves have a different shape: very narrow to needle-shaped or cylindrical.

Inflorescences and flowers

Usually an unleaved inflorescence stem is present. The flowers are grouped in terminal, simple or branched, mostly racemose , rarely eared or, if the inflorescence axes are strongly shortened, head-like inflorescences . Each flower is located in the axilla of a large to tiny bract . In some genera, a second small bract is formed at the base of each peduncle.

The hermaphrodite flowers are like most monocots ( monocots trifoliate) and most radial symmetry . In very few Daubenya species, the lower flowers of an inflorescence are more or less double-lipped, i.e. zygomorphic . The flowers of some species have a strong scent. The colors of the bracts range from greenish to greyish, from white to blue and from yellow to orange to red. In many Lachenalia species, the bracts are multicolored, often with dark tips. There are two circles with three bracts each; they are all the same or only those of a circle are the same. They are free or overgrown at their base. There are usually two (exception: the species of the genus Albuca , there is a missing circle) circles with three free stamens each, mostly all stamens are fertile . The stamens can be fused with the bloom cladding sheets. Three carpels have become a top permanent ovary grown; only with Bowiea is he semi-dependent. The upper ovary distinguishes the Scilloideae from the onion-forming Amaryllidaceae . There are septal nectaries . Each of the three ovary chambers contains a few to many ovules in the center . The stylus is simple. The flowers of most species can be kept for a long time (a few days), with the exception of all Drimia species where they can only be kept for a few hours to a day at most.

The pollination is mainly by insects and some species of birds. Many species are pollinated by solitary bee species. Species with brightly colored flowers such as the Orange Milky Star ( Eliokarmos dubius , Syn, Ornithogalum dubium ) and Daubenya aurea are pollinated by beetles from the Hopliini tribe of the Rutelinae within the Scarabaeidae . The species of the genus Dipcadi (which, according to some authors, belong to the broad genus Ornithogalum ) are adapted to pollination by moths; its flowers give off a strong scent at night. In some Lachenalia species and Daubenya species, pollination takes place by nectar birds ; these species typically have red to orange, trumpet-shaped flowers that secrete copious amounts of nectar . Some Massonia species are pollinated by rodents (Rodentia).

Fruits and seeds

The dry capsule fruits are very variable in shape and open with three lobes. Usually the seeds are black due to phytomelans . The flattened seeds of the Tribus Urgineeae have wing-like edges and are spread by the wind. The tribe of the Hyacintheae has smooth and spherical to pear-shaped seeds.

distribution

The distribution is mainly the Old World. The centers of biodiversity are the Capensis with around 200 species, especially in winter rain areas, and the Mediterranean area . There are natural occurrences all over Europe to the Urals , in Africa except the areas of the Sahara and the tropical rainforest, on the Arabian Peninsula, from Asia Minor to the Caucasus , in Central Asia , in East Asia, on the Indian subcontinent and in the Himalayas . Only the genus Oziroë occurs in the South American Andes.

Systematics

The generic names Hyacinthus , Ornithogalum and Scilla were already used in ancient Greece. In Species Plantarum has Linnaeus first published in 1753, these three genera.

The group used to contain fewer genera. Especially since the molecular genetic investigations, the broad old genera have proven to be paraphyletic and had to be divided into many smaller genera so that they are monophyletic . All in all, monophyletic genera and tribe could be set up.

The family group around Drimia has been scientifically processed several times since 1998 and structured differently. At Manning 2004 they gave Drimia s. l. the largest extent with over 100 species. By Speta (1998) they were in the 13 genera Drimia Jacq. ex Willd. (with ten species), sea onion ( Charybdis Speta ), Urginea Steinh. , Ebertia Speta , Fusifilum Raf. , Litanthus Harv. , Rhadamanthus salisb. , Rhadamanthopsis (Obermeyer) Speta , Schizobasis Baker , Tenicroa Raf. , Thuranthos C.H.Wright , Urginavia Speta and Urgineopsis Compton. been divided. This controversial discussion is likely to continue.

The hyacinth plants were divided as a family by Franz Speta (1998) and Martin Pfosser & Franz Speta (1999) into four morphologically difficult to distinguish, but molecular-genetic clearly monophyletic subfamilies and contained around 70 genera with around 1000 species . In the course of APG III , Mark W. Chase, James L. Reveal and Michael F. Fay (2009) placed the Hyacinthaceae family as a subfamily Scilloideae to the Asparagaceae family , which gave the previous subfamilies the tribe rank . The name Scilloideae results from the priority rule . This classification of the hyacinth family in the Asparagaceae s. l. not all scientists follow (e.g. Goldblatt et al. 2012).

The new subfamily Scilloideae contains four tribes with the genera:

  • Zagrosia persica (house number) Speta : It occurs in southeastern Turkey, Iraq and Iran.

Usage, ingredients and history

The white sea onion ( Drimia maritima ) was already used medicinally in ancient times.

Some South African species such as Eliokarmos thyrsoides , Ledebouria cooperi , Ledebouria inguinata , Ledebouria ovatifolia , Ledebouria revoluta , Gaulteria saundersiae and some species of the Urgineeae are poisonous to grazing cattle. The poisonous scillirosides (also a bufadienolide) are used as rat poison.

Often with mucus and Oxalatraphiden filled idioblasts present.

Only a few species of the Scilloideae serve as human food. In Greece the onions of Muscari comosum are eaten and in France the inflorescences of Loncomelos pyrenaicus are eaten as a vegetable. In Africa, the San eat onions of Ledebouria apertiflora and Ledebouria revoluta .

Many species and their varieties are used as ornamental plants in parks, gardens, balconies, as indoor plants and as cut flowers . Species and their varieties from the genera Chouardia , Hyacinthoides , Hyacinthus , Muscari , Othocallis , Puschkinia and Scilla are spring bloomers in the northern hemisphere , they were planted in parks and gardens and tend to grow wild. In South Africa and other arid areas, species such as Eucomis , Galtonia and Veltheimia are planted in parks and gardens. For example, Eliokarmos thyrsoides and related species are cut flowers.
