Trimezia is a genus of flowering plants in the family Iridaceae, native to the warmer parts of southern Mexico, Central America, South America, Florida, and the West Indies. Trimezia is placed in the tribe Trimezieae. The division of the tribe into genera has varied considerably. In one approach, it contains only the genus Trimezia, which then includes the genera Neomarica, Pseudotrimezia and Pseudiris. In other approaches, two to five genera are recognized, sometimes also including the genus Deluciris.
Libertia pulchella, the pretty grass-flag, is a plant in the iris family (Iridaceae). It is native to Papua New Guinea, New Zealand and Australia, where it occurs in New South Wales and Victoria and Tasmania. The flowering scape rises above the linear leaves producing 3 to 6 cream-coloured flowers.
Sisyrinchium micranthum, commonly known as blue pigroot or striped rush-leaf, is a grass-like species in the iris family, Iridaceae. It is native to Mexico, Central America, and South America and widely naturalised elsewhere. The white to cream flowers are between 10 and 20 mm in diameter and have blue to purple centres. These are followed by rounded 3 to 8 mm brown capsules that enclose the dark brown seeds.
Libertia ixioides is a flowering plant in the family Iridaceae. The species is endemic to New Zealand. It is a rhizome-forming herbaceous perennial. The Latin ixioides means like an ixia, due to its similarities with that plant species.
Sisyrinchium albidum, commonly known as white blue-eyed grass, is a species of flowering plant in the family Iridaceae.
Libertia chilensis, synonym Libertia formosa, called the New Zealand satin flower, snowy mermaid, or Chilean-iris, is a species of flowering plant in the iris family, Iridaceae, native to the Juan Fernández Islands, central and southern Chile, and southern Argentina. It can also be found growing wild in the San Francisco Bay Area and San Bernardino County in California, where it is an introduced species. A rhizomatous evergreen perennial, it has gained the Royal Horticultural Society's Award of Garden Merit.
Sisyrinchium rosulatum, commonly known as annual blue-eyed grass and fairy star, is a species of wildflower. It is a member of the iris family (Iridaceae). It grows in the southeastern United States and Hawaii. A deciduous annual, it grows in dry coastal plains growing to about 1–3 feet (0.30–0.91 m) high and having blooms in various colors. The species may overlap with Sisyrinchium micranthum.
The genus Chalepogenus, consisting of 21 species of oil-collecting apid bees, demonstrates oligolecty by foraging on oil-producing flowers from the families Calceolariaceae, Iridaceae and Solanaceae. These oil-flowers are abundant in South America, where Chalepogenus is endemic. In contrast to honey bees, Chalepogenus species do not collect nectar; instead, they gather floral oil for various purposes, including provisioning their larvae, constructing nests, and sustaining foraging adult bees. Although oil collection has been reported to be performed by females only, both males and females have specialised oil-collecting structures.
