Brown & Folsom: WILD ORCHIDS OF THE WHITE MOUNTAINS OF NEW HAMPSHIRE AND MAINE Cypripedium arietinum R. Brown ram’s-head lady’s-slipper Range: Manitoba and Minnesota east to Nova Scotia, south to Massachusetts In the White Mountains region: very rare and local Plant: terrestrial, 10-33 cm tall Leaves: 3-4; elliptic-lanceolate, bluish-green; 1.5-3.0 cm wide × 5-10 cm long Flowers: 1, rarely 2 in the forma biflorum; dorsal sepal ovate-lanceolate, greenish with purple-brown veining, lateral sepals separate, slender, slightly twisted, bronzygreen to purplish; petals similar to lateral sepals; lip funnelshape, broadened above; white with pink-deep raspberry veining or, in the forma albiflorum, white with pale green petals and sepals; individual flower size ca. 1.5 × 2 cm; lip 1 cm long with an oval fissure densely pubescent on the margin Habitat: mixed hardwood and coniferous forest; usually in circumneutral to calcareous soils Flowering period: late May though June The ram’-head lady’s-slipper is the smallest flowered 216 and most inconspicuous of all of our species of Cypripedium. The flowers are about the size of the tip of your finger and are held aloft at the top of the stem. In northern New England it is nowhere common southward is exceedingly rare. Plants are usually confined to calcareous woodlands. The shape of the lip is unique among our North American species. This species is of conservation concern in every state and province in which it occurs. In the White Mts. region it is known from an historical site near Shelburne just north of Rt. 2 in Coös County, NH. and just south of the region is an extant site near Moultonboro This species should be eagerly sought within the WMNF and environs.
Brown & Folsom: WILD ORCHIDS OF THE WHITE MOUNTAINS OF NEW HAMPSHIRE AND MAINE Cypripedium parviflorum Salisbury var. makasin (Farwell) Sheviak northern small yellow lady’s-slipper Range: British Columbia south to northern California, east to Newfoundland, south to Illinois and Pennsylvania In the White Mountains region: very rare and known only from an historical site in Coös County, NH Plant: terrestrial, 15-35 cm tall Leaves: 3-5; alternate, spreading; ovate to ovate-elliptic to lance-elliptic, 1.6-12.0 cm wide × 5.0-20 cm long; the outer surface of the lowermost sheathing bract sparsely pubescent to glabrous when young Flowers: 1-2(3); sepals and petals suffused with a dark reddish-brown or madder, often appearing as a uniform color; lateral sepals united; petals undulate and spiraled to 10 cm long; lip ovoid, slipper-shaped, usually a deep, rich yellow, with scarlet to purple markings within the lip; individual flower size ca. 2.0 × 3.0 cm; lip 1.5-2.9 cm long, the opening ovate-oblong at the base of the lip; intensely sweetly scented Habitat: mesic to calcareous, moist woodlands, streamsides, bogs, and fens Flowering period: June-July The small, richly colored and intensely fragrant flowers of the northern small yellow lady’sslipper are, in most instances easily distinguished from those of the large yellow lady’sslipper. Where the confusion occurs is in finding plants of Cypripedium parviflorum var. pubescens that have rich, dark petals. Usually these plants also have large lips. Habitat is often a help but it is important to check out all of the criteria. In the White Mts. region is known from an historical site near Shelburne just north of Rt. 2 in Coös County, NH. 217
