Wilkesia hobdyi
''Wilkesia hobdyi'', the dwarf iliau, is a species of flowering plant in the sunflower family, Asteraceae, that is endemic to the island of Kauai in Hawaii. It was first collected in 1968, and was not formally described until 1971. The number of living plants is estimated at fewer than 300. It is considered Critically Imperiled in global rank which means it is at very high risk of extinction.〔(【引用サイトリンク】title=CPC National Collection Plant Profile: Wilkesia hobdyi )〕 It has been a federally protected species since 1992. The ''Wilkesia'' genus is one of three genera constituting the silversword alliance, a group of highly diverse yet genetically exceedingly closely related species, all thought to be descended from a colonizing ancestor related to the tarweed of North America.〔(【引用サイトリンク】url= http://www.botany.hawaii.edu/faculty/carr/silversword.htm )〕
==Description==
''Wilkesia hobdyi'' is a perennial shrub with branches reaching a length of extending vertically from the base. Branch tips yield whorl, rather than spirals, of narrow, flat, grass-like, somewhat thick leaves around long. Cream-colored flowers are produced in inflorescences in diameter. Flowering has been observed most often in the winter months, but
also during June. This species is probably pollinated through outcrossing and is probably self-incompatible. Insects are the most likely pollinators.〔 ''Wilkesia'' die after flowering.〔
