Solstad 03-042, 8 Aug. 2003 (Yukon Government Herbarium, photo DAO). This Amphi-Beringian species was previously known in North America from two stations in Alaska, one in the Mackenzie Delta, and two localities in Central Yukon where it was considered rare by Douglas et al. (1981) [Cody 1996]. The specimen cited above is from a site about 300 kilome- ters southwest of sites in the vicinities of Mayo and Elsa. Carex lenticulahs Michaux var. dolia (M. E. Jones) L. A. Standley (C. enanderi Hulten), Enander's Sedge - Yukon: Kluane National Park, rare, seen only along creek near camp, Fisher Glacier near Alsek River, base camp, 60°08'31"N 138°13'13"W, B. A. Bennett 03-955, 6 July 2003 (DAO) (determined by can- didate Julie A. Dragon from the University of Vermont). First reported from Yukon by Standley et al. (2002) this is a new variety in the Yukon Territory and should be added to the Rare Vascular Plants of the Yukon (Douglas et al. 1981). It can be separated from Carex lenticularis var. lenticulahs as follows (from Flora of North America Volume 23): A. Terminal spike gynecandrous (with pistillate flowers at the apex); proximal spike not exceeding cm; peduncle less than 1 cm; perigynia ovoid var. dolia A. Terminal spike usually staminate; proximal spike longer than cm; peduncle 1 cm or longer; perigynia ovoid to ellipsoid var. lenticularis Carex eleusinoides is similar in inflorescence morpholo- gy, but may be distinguished by its red basal sheaths and short, veinless perigynia. This species was considered rare in the Territory by Dou- gl
