Carex albula
Carex albula, common name white sedge, is a species of sedge (in the Cyperaceae family). It is endemic to the South Island of New Zealand.[4] According to Plants of the World online, it has no synonyms.[5] However the New Zealand Plant Conservation Network lists Carex comans var stricta Cheeseman as a synonym.[4] DescriptionIt is a densely tufted sedge growing from 250 to 350 mm tall, and may be buff-coloured, an almost bleached white, or green or red. The culms are smooth and 50-200 mm by 0.5 mm, often having a deep groove. The leaves are numerous and the basal sheaths are dark brown to purple-red. The terminal spike is male with the other spikes being female.[4] It flowers from October to December and fruits from October to September[4] and the nuts are dispersed by granivory and wind.[6] Distribution and habitatIt is found in the South Island from the Mackenzie Basin, to Waitaki and Central Otago, on alluvial terraces, and slopes and on river flats.[4] Conservation statusThe IUCN Redlist declared its conservation status to be of "least concern" (LC).[7] However, assessments under the New Zealand Threat Classification System (NZTCS), declared it to be "At Risk – Declining" (Dec) in 2013, and in 2017 to be "Threatened – Nationally Vulnerable" (NV).[1] References
