Xyris Congensis
''Xyris'' is a genus of flowering plants, the yelloweyed grasses, in the Xyridaceae, yellow-eyed-grass family. The genus counts over 250 species, widespread over much of the world, with the center of distribution in the Guianas. The Leaf, leaves are mostly distichous, linear, flat, and thin or round with a conspicuous sheath at the base. They are arranged in a basal aggregation. The small, yellow flowers are borne on a spherical or cylindrical Spike (botany), spike or Head (botany), head (inflorescence). Each flower grows from the axil of a leathery bract. The fruit is a nonfleshy, dehiscent Capsule (botany), capsule. In ''Xyris complanata'', a single flower bud on the spike appears in the morning, and expands into a conspicuous flower during the afternoon. The APG IV system, of 2016, places the genus in family Xyridaceae, into the order Poales in the clade commelinids, in the monocots.

Sisyrinchium Californicum
''Sisyrinchium californicum'' is a species of flowering plant in the iris family known by the common names golden blue-eyed grass, yellow-eyed-grass, and golden-eyed-grass. It is native to the west coast of North America from British Columbia to central California, where it grows in moist habitat, often in coastal areas. Description ''Sisyrinchium californicum'' is a rhizomatous perennial herb producing a pale green, nonwaxy stem which grows up to about 60 centimeters tall. The foliage turns dark brown or black as it dries. The flat, narrow leaves are grasslike. The flower has six tepal A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ...s each between 1 and 2 centimeters in length. They are light to bright yellow, often with brown veining.

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders ( Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as th ...
