I did not make another journey for a week or more. On June 10th, I ventured through the Glen of Comus to see the colony of the two hundred Moccasins. An albino—a pure white flower of _Cypripedium acaule_—was found recently by a lad in the district. He reports that he collected it amid a group of thirteen Pink Moccasin-Flowers, apparently the only pale one of the sisters. Upon close examination of the structural parts of the albino, I observed that the left anther had not developed at all. It appeared blasted in embryo, and now looked like a brown smeared spot. The sepals and lateral petals were of a rich chrome yellow. The dainty labellum was pure white, of a pearl-like texture in the veining, and tinged with chrome on the crest of the moccasin. It was indeed a strange, beautiful flower. I had always supposed that an albino of any species of orchid was pure white throughout its parts, and was therefore surprised to find the sepals and side petals yellow. Albinos of this species have been collected in this district for four seasons. A colony, found near the schoolhouse, produced six white blossoms. The children, calling them faded Pink Moccasins, believed them to have lost their color after maturing. It appears from its persistence that the variety is permanent, and not the freak of a season. The abnormal anther may be present in all albinos. If so, it is evident that evolution is taking place in the Pink Moccasin-Flower through the suppression of one anther in genus _Cypripedium_, which possesses two, while all other genera of the family have but one anther. The colony of the Showy Lady’s Slipper in Rattlesnake Swamp, producing forty-two blossoms in 1899, unfolded but fifteen flowers this season. For reasons unknown to me, it was not a good year for Cypripediums. XII Saucy Jays and Polypores To arched walks of twilight groves, And shadows brown, that Sylvan loves, Of pine, or monumental oak, Where the rude axe, with heaved stroke, Was never heard the nymphs to daunt, Or fright them from their hallowed haunt.
