Triteleia is a genus of monocotyledon flowering plants also known as triplet lilies. The 16 species are native to western North America, from British Columbia south to California and east to Wyoming and Arizona, with one species in northwestern Mexico. However, they are most common in California. [1] [2] [3] They are perennial plants growing from a fibrous corm roughly spherical in shape. They get their name from the fact that all parts of their flowers come in threes.

Taxonomy and systematics

The Angiosperm Phylogeny Group's 2009 revision placed the genus in family Asparagaceae, subfamily Brodiaeoideae [4] (having previously placed treated Brodiaeoideae as a separate family Themidaceae). Other modern authors place it in the family Alliaceae.[ citation needed ] Both these families are in the order Asparagales.

There are currently 16 recognized species in Triteleia. One species, Triteleia ixioides, has five well-defined subspecies. Varieties and subspecies have been proposed within several other Triteleia species, but these are no longer widely accepted. Some common species that are now placed in genus Triteleia were formerly placed in genus Brodiaea , and as a consequence the word "brodiaea" has been incorporated into some of their common names.

<span class="mw-page-title-main">Asparagales</span> Order of monocot flowering plants

Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species.

<span class="mw-page-title-main">Brassicales</span> Order of dicot flowering plants

The Brassicales are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. One character common to many members of the order is the production of glucosinolate compounds. Most systems of classification have included this order, although sometimes under the name Capparales.

<span class="mw-page-title-main">Liliales</span> Order of monocot flowering plants, including lilies

Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription varying greatly from one taxonomist to another. Previous members of this order, which at one stage included most monocots with conspicuous tepals and lacking starch in the endosperm are now distributed over three orders, Liliales, Dioscoreales and Asparagales, using predominantly molecular phylogenetics. The newly delimited Liliales is monophyletic, with ten families. Well known plants from the order include Lilium (lily), tulip, the North American wildflower Trillium, and greenbrier.

Urticales is an order of flowering plants. Before molecular phylogenetics became an important part of plant taxonomy, Urticales was recognized in many, perhaps even most, systems of plant classification, with some variations in circumscription. Among these is the Cronquist system (1981), which placed the order in the subclass Hamamelidae [sic], as comprising:

<i>Triteleia ixioides</i> Species of flowering plant

Triteleia ixioides, known as prettyface or golden star, is a monocotyledon flowering plant in the genus Triteleia. It is native to northern and central California and southwestern Oregon, where it can be found in coastal and inland coniferous forests and other habitat. It is a perennial wildflower growing from a corm. It produces one to two basal leaves up to 50 centimeters long by 1.5 wide. The inflorescence arises on an erect stem up to 80 centimeters tall. It is an umbel-like cluster of several flowers each borne on a pedicel up to 7 centimeters long. The flowers are variable in size, measuring one to nearly three centimeters in length. They are pale to bright yellow, or sometimes purple-tinged white. There are six tepals with darker midveins in shades of green, brown, or purple. The lobes are funnel-shaped and may open flat or somewhat reflexed. The six stamens form a fused tube that protrudes from the corolla; they have broad, flat filaments and whitish, yellowish, or blue anthers.

<span class="mw-page-title-main">Lilioid monocots</span> Grade of flowering plant orders, within Lilianae

Lilioid monocots is an informal name used for a grade of five monocot orders in which the majority of species have flowers with relatively large, coloured tepals. This characteristic is similar to that found in lilies ("lily-like"). Petaloid monocots refers to the flowers having tepals which all resemble petals (petaloid). The taxonomic terms Lilianae or Liliiflorae have also been applied to this assemblage at various times. From the early nineteenth century many of the species in this group of plants were put into a very broadly defined family, Liliaceae sensu lato or s.l.. These classification systems are still found in many books and other sources. Within the monocots the Liliaceae s.l. were distinguished from the Glumaceae.

<span class="mw-page-title-main">Allioideae</span> Large subfamily of flowering plants in the family Amaryllidaceae

Allioideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It was formerly treated as a separate family, Alliaceae. The subfamily name is derived from the generic name of the type genus, Allium. It is composed of about 18 genera.
