Brown & Folsom: WILD ORCHIDS OF THE WHITE MOUNTAINS OF NEW HAMPSHIRE AND MAINE Gymnadeniopsis clavellata (Michaux) Rydberg var. ophioglossoides (Fernald) Schrenk northern club-spur orchis Range: Ontario east to Newfoundland, south to northern New England In the White Mountains region: locally common in open, wet areas at northern and higher elevations Plant: terrestrial, 5-15 cm tall Leaves: 1; cauline, ovate, 1-2 cm wide × 3-5 cm long, an occasional slender bract also present on the stem. Flowers: 3-10; arranged in an short, dense, crowded terminal raceme; flowers usually twisted to one side; sepals ovate, petals linear, enclosed within the sepals forming a hood; lip oblong, the apex obscurely 3-lobed; perianth yellow-green to frosty-white; individual flower size 0.5 cm, not including the 0.5 cm spur, the small tip swollen (clavate) Habitat: exposed areas at northern or higher elevations; gravelly barrens, tundra, stream and lakeshores Flowering period: July to August This very distinctive variety of the more common club-spur orchis is often found in very large colonies in wet gravels, roadside ditches and mountain seeps throughout the northern portion of the Maritimes and Great lakes. The little plants, especially when in bud, resemble the adder‖s-tongue fern, Ophioglossum, in both the single leaf and short little crowed inflorescence. It is not unusual to find areas that are nearly paved with these little gems. 226
Brown & Folsom: WILD ORCHIDS OF THE WHITE MOUNTAINS OF NEW HAMPSHIRE AND MAINE ISOTRIA consists of only two species, both of which are found in the eastern United States and adjacent Canada. They are related to the genera Pogonia and, more distantly, Triphora, and early in its history was placed in the genus Pogonia. Isotria medeoloides (Pursh) Rafinesque small whorled pogonia FEDERALLY LISTED AS THREATENED Range: Michigan east to Maine, south to Missouri and South Carolina In the White Mountains region: very rare in Carroll County Plant: terrestrial, mature plants up to 15 cm tall, shorter (8-12 cm) in flower Leaves: 5 or 6; in a whorl at the top of the stem, up to 1 cm wide × 5 cm long Flowers: 1 or 2; sepals and petals greenish-yellow, wide spreading; lip white; individual flowers ca. 2-3 cm across Habitat: various wooded habitats; favoring beech, mixed pines, etc.; often near seasonal runoffs Flowering period: April-May, usually before the trees leaf out The small whorled pogonia was one of the first orchids to be listed by the federal government under the Endangered Species Act. Very rare, and known from only three stations at the extreme northern limit of its range. This is an excellent example of a species originally thought to be one of the very rarest in North America, and, with the advent of more people, both professional and amateur, searching and finding many new sites. 227
