Luzula spicata (L.) DC.
Spiked Wood Rush
- State Rank: S1
- Global Rank: G5
- State Status: Threatened
Habitat: Gravel talus and peaty openings in alpin areas. [Alpine or subalpine (non-forested, upland)]
Range: Circumboreal, south to the high mountains of New York and New England.
Aids to Identification: Spiked wood-rush grows in very dense, low tufts, up to 10-30 cm in height. There are many basal leaves and only 2 or 3 very narrow leaves on the stem. The flowers grow in small, dense clusters, with no flowering stalks, forming a spike 1-3 cm long. Fruits are purple-brown and the seeds have a short, rounded appendage. This species can be distinguished from another rare wood-rush, L. confusa, by the bracts that subtend the cluster of flowers. The bracts of L. spicata are much longer, projecting beyond the flowers.
Ecological characteristics: Known in Maine from alpine pondshores on Mt. Katahdin.
Phenology: Flowers June - August.
Synonyms: Juncoides spicatum (L.) Kuntze.
Known Distribution in Maine: This rare plant has been documented from a total of 1 town(s) in the following county(ies): Piscataquis.
Reason(s) for rarity: An arctic species, disjunct from principal range.
Conservation considerations: Populations could be threatened by heavy recreational (hiking) use.
