Dubautia pauciflorula

''Dubautia pauciflorula'' is a rare species of flowering plant in the aster family known by the common name Wahiawa Bog dubautia. It is endemic to Hawaii where it is known only from the Wahiawa Mountains on the island of Kauai.〔Carr, G. D. (''Dubautia pauciflorula''. ) Hawaiian Silverswords.〕
There are fewer than 50 individuals remaining.〔〔USFWS. (''Dubautia pauciflorula'' Five-year Review. ) April 2009.〕 It was federally listed as an endangered species of the United States in 1991.〔(''Dubautia pauciflorula''. ) The Nature Conservancy.〕 Like other ''Dubautia'' this plant is called ''na`ena`e''.〔USFWS. (Species Reports: Listed Plants. )〕
This member of the silversword alliance was first collected in 1909, and again in 1911, but it went without a name for many decades. It was not collected again until 1979 and it was finally described as a new species in 1981.〔St. John, H. and G. D. Carr. (1981). (Two new species of ''Dubautia'' (Compositae) from Kauai. ) ''Bulletin of the Torrey Botanical Club'' 108:2 198-204.〕 It grows in wet rainforest habitat near streams.〔 The area receives up to 500 centimeters of precipitation annually. This plant is a shrub growing up to 3 meters tall by 3 meters wide, with smooth, oppositely arranged leaves. Yellow flowers are borne in heads of two to four.〔〔
Threats to this species and its habitat include feral pigs and invasive plant species such as ''Melastoma candidum''.〔 Conservation efforts include the collection of seeds.〔
