Carex berggrenii, common name Berggren's Sedge, is a species of sedge (in the Cyperaceae family). It is endemic to New Zealand, being found on both the North and the South Islands.[1]
Description
It is a small, tufted, dark red-purple or orange-red sedge. Its smooth culms (circular in cross-section) are 15-30 mm long are flattened above, and almost enclosed by light brown sheaths. The linear, almost flat leaves are 30-60 mm by 1-2.5-3 mm, with distinct nerves, and blunt apices. The terminal spike is male (on a peduncle) with the remaining sessile (or almost sessile) spikes being female, and crowded around the base of the male spike. The bracts which subtend the inflorescence are longer than it.[1]
It flowers from October to February and fruits from October to June, [1] and the nuts are dispersed by granivory and wind.[3]
Distribution & habitat
It is found in the Central Ranges of the North Island. In the South Island it is found generally easterly from Lake Tennyson south. It is a montane to subalpine wetland species growing on the margins of lakes and streams.[1]
Conservation status
Assessments under the New Zealand Threat Classification System (NZTCS), declared it to be "At Risk – Naturally Uncommon" (NU) in 2013, and in 2017 to be "At Risk - Declining" (Dec).[4]
