Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial because recent phylogenetic studies have suggested...

The influence of vegetation and microtopography on fine-scale variability of thaw depth is largely unknown but potentially important for improving modeling of ecosystem–permafrost interactions. To elucidate their influence, we measured tree density, shrub cover and cryptogam presence (lichen and bryophyte) on forested permafrost peat plateaus in th...

La presence de la naiade grele, Najas gracillima (Najadaceae), dans la flore aquatique indigene du Quebec est confirmee. Cette espece sensible a la pollution est en declin dans toute son aire naturelle nord-americaine en raison de l’eutrophisation des lacs et des cours d’eau. Pour faciliter l’identification de cette rarete, une cle des Najas de la...

We present the first survey of the vascular flora of Scotty Creek, a peatland-dominated watershed with discontinuous permafrost about 60 km south of Fort Simpson, Northwest Territories (NWT). Of the 140 vascular plant taxa found at Scotty Creek, two are additions to the boreal flora of NWT: Arethusa bulbosa (Dragon's-mouth, Orchidaceae) and Carex p...
