WILDFLOWERS OF NEW MEXICO

 
 

A densely packed spike (raceme) of 50–100 small, whitish-green flowers covers the upper half of the stem, typically 8–28 inches tall. Note the flowers have a sweet aroma, a slender, cylindrical spur, and the lower lip is slightly enlarged at the base and narrows slightly to a rounded tip.


FLOWER: June–August. Distinctively whitish-green flowers in NM, 3/8–5/8 inch long (1–1.5 cm); two side sepals fold back at about 45 degrees (not folded against the spur); hood formed by upper sepal and two lateral petals; lip petal points downward, is narrowly lance-shaped, to 1/2-inch long (12 mm), with the base slightly wider than the rounded tip; the nectar spur curves downward, is slender, cylindrical, and about the same length as the lip; the stamens and style are fused to form a column about half as long as the hood. After pollination, the lip curves upward to cover the column.


LEAVES: Alternate. Blades oblong to lance-shaped, 2–12 inches long (5–30 cm) becoming smaller up the stem.


HABITAT: Wet soils of mountain bogs, seeps, meadows, streamsides, roadsides; ponderosa pine-Douglas fir, spruce, mixed conifer forests.


ELEVATION: 7,000–11,500 feet.


RANGE: CO, ID, MT, NM, OR, UT, WA, WY; widespread in Rocky Mts. and Great Lakes states eastward to Maine.


SIMILAR SPECIES: Tall White Bog Orchid, P. dilatata, has pure white flowers and a lip with a broad base and narrow tip. Northern Green Orchid, P. aquilonis, has unscented, yellow-green flowers, lateral sepals that fold back against the spur, a more club-shaped spur shorter than the lip, and is not densely flowered.


NM COUNTIES: In NM mountains in mid- to high-elevation, wet habitats: Bernalillo, Catron, Colfax, Lincoln, Los Alamos, Mora, Otero, Rio Arriba, San Juan, San Miguel, Sandoval, Santa Fe, Taos.
