Part 34

New England Range—There are no authoritative stations reported as yet, although the author collected intermediate forms of H. hyperborea in Dimmick Swamp, Pownal, Vermont, July, 1903, answering to Dr. Rydberg’s descriptions of this form. It is also reported by Marcus White and A. LeRoy Andrews for Pownal Swamps.

7.—HABENARIA DILATATA (Pursh) Hooker, 1814-1825

TALL WHITE NORTHERN ORCHIS

The specific name, dilatata, refers to the dilated condition of the labellum of this orchid.

A tall slender or stout bogland orchid, with fleshy-fibrous or tuberous roots. June 2d-August 23d.

=Flowers= white, small, in a densely flowered spike 2-10 inches long. Slightly fragrant. Not constructed for self-fertilization as the closely allied species H. hyperborea. =Labellum= entire, dilated, or obtusely 3-lobed at base. =Spur= blunt and incurved. =Sepals= ovate, obtuse, and small. =Stem= slender, often stout, inferring that an intermediate form exists, which Dr. Rydberg has designated specifically as fragrans. =Leaves= lanceolate. =Seed-capsule= much twisted.

Continental Range—From Ankow River, Ocean Cape, Alaska, and Unalaska in latitude 60° North; southward to Litchfield, Connecticut, Amherst, Massachusetts, and Pennsylvania; westward to Minnesota, Wyoming, Colorado, also occurring in the cañons of Clear Water Valley, Idaho.

New England Range—Maine, common; New Hampshire, frequent; Vermont, frequent; Massachusetts, infrequent; Rhode Island, not reported; Connecticut, rare.

8.—HABENARIA FRAGRANS (Rydberg) Niles, 1901-1903

FRAGRANT SLENDER BOG-ORCHIS

The specific name, fragrans, refers to the exquisite fragrance of this species, which is so closely allied with H. dilatata and of which it appears to be a form.

Slender bogland orchid, with fleshy-fibrous roots. July.

=Flowers= small, pure white, very fragrant; in a slender spiked raceme. =Labellum= narrowly linear, dilated at the base, obtuse, shorter than the curved filiform spur; otherwise as the preceding species. =Sepals= lanceolate, acutish, strongly striate. =Stem= very slender and leafy above, 8-12 inches high. =Leaves= linear, several.

Continental Range—Reported from a single station in Vermont. Slender forms of H. dilatata, very fragrant and slightly so, are present in the bogs of Pownal, Vermont, and North Adams, Massachusetts, where the writer has collected them, believing that they were forms brought about by the intergrading of the bogland Habenarias closely associated. Species of Habenaria appear to produce natural hybrids readily.

New England Range—Vermont.

9.—HABENARIA BRACTEATA (Willdenow) R. Brown, 1805-1813

LONG BRACTED ORCHIS

The specific name, bracteata, refers to the long bracts, subtending the seed-capsules of this species.

A slender bracted bogland orchid, with fleshy-fibrous roots. May 8th-July 14th-August 12th.

=Flowers= small, greenish, in a loosely flowered spike, 3-5 inches long, subtended by long bracts. =Labellum= long, spatulate 2-3 toothed or lobed, twice as long as sac-like spur. =Sepals= ovate-lanceolate, spreading, dilated, at base; =petals= very narrow, threadlike. =Stem= leafy, slender, or stout, 6 inches to 2 feet high. =Leaves= lanceolate, oval.

Continental Range—From Sitka and Unalaska to the Great Plains, approaching the Rocky Mountains in latitude 55° North; southward throughout New England to North Carolina; westward to Minnesota, North and South Dakota, and Montana.

New England Range—Maine, common; New Hampshire, common; Vermont, common; Massachusetts, frequent; Rhode Island, rare; Connecticut, rather rare.

10.—HABENARIA CLAVELLATA (Michaux) Sprengel, 1803-1826

SMALL YELLOWISH BOG-ORCHIS—SMALL WOOD-ORCHIS

The specific name, clavellata, refers to the club-shaped appendages of stigma or clavate spur attached to the flowers of this species.

A small bogland or woodland orchid, with fibrous roots. May 17th (Missouri), June (Alabama); July 15th-August (Maine).

=Flowers= small greenish-yellow, in a loosely flowered spike ½-2 inches long. =Labellum= dilated, 3-toothed at apex; spur longer than ovary, clavate. =Sepals= and =petals= ovate. =Stem= 8-18 inches high. =Leaf= 1, near the base, 1-3 bracts above.

Continental Range—From Lake Huron, Newfoundland, southward to Alabama; westward to Indiana, and Missouri. Ascends 6000 feet altitude in North Carolina.
