CATALOGUE. 265 



sion or pit; anther nearly sessile, of two parallel cells, open above, and free above 

 from column, pollen masses two, not divided, or ivith a mere sulcation, attached to 

 the minute gland on the tip of the column ; mature capsules 3-4" long, oval. 



It is partieulary remarkable in having a dense spike of sessile flowers. 

 Mount Graham, Arizona, at an elevation of 9,500 feet (734). It appears 

 to be extremely rare. I am indebted to Mr. Watson for indicating the 

 genus, and also for the information that the plant was probably undescribed. 



Habenaria leucostachys, — ? — Stem leafy ; leaves oblong-lanceolate, 

 obtuse ; spike long, densely flowered ; bracts about as long as the flower. 

 My specimen from Willow Spring, Arizona (269), shows a well-marked, 

 hooded, posterior sepal, such as we might expect to find in H. dilatata, but 

 is without the dilated base to the lip and the trowel-shaped rostellum of th,e 

 latter species ; lip lanceolate, not longer than the somewhat curved spur. 

 The locality whence this specimen was obtained was a very cold, damp one 

 (even though in Arizona), at an altitude of 7,195 feet. 



Habenaria hyperborea, R. Br. — Colorado (965). 



Habenaria dilatata, Gray. — Colorado ; in company with the above. 

 Quite too near some forms of the above species, as the characters on which 

 the distinctions are founded vary immensely. 



Epipactis gigantea, Dougl. — Nevada. 



Goodyera Menziesii, Lindl. — Entirely in accord with the figure (Spi- 

 ranthes decipiens, Hook.), 204, Hook. Fl. Bor. Amer., except that on either 

 side of the base of the lip, in some of my specimens, there is a distinctly 

 serrated crest. Other flowers from the same spike have a single crest 

 in the median line. 



Mount Graham, Arizona, at 9,500 feet elevation (749). 



Spiranthes Romanzoviana, Chamisso. — Mount Graham, Arizona, at 

 9,500 feet elevation (752) ; Utah ; Colorado. 



Corallorhiza Macr^ei, Gray 1 — I name this specimen so with great 

 doubt. It will more likely prove to be new, I think. It differs from the 

 genuine C. Macrcei in its smaller flowers, short, thick column, spur short, 

 thick, and truncate, the lip oval, and with a distinct auricle on either side 

 at base. 



Mount Graham, Arizona, at 9,500 feet (750).— This peak appears to
