GREENMAN, — PHANEROGAMS, 475 
Plant glabrous throughout, aphyllous: stems from an ascending 
thizome, 3 to 7 dm. high, purplish, provided with 2 to 4 sheathing 
obtuse or acutish somewhat scarious nerved bracts: racemes muany- 
flowered; rhachis subangulate; floral bracts small, scarious: perianth 
1.5 em. broad, yellowish white or purplish in the dried state, pedicellate, at 
first erect, later reflexed ; the persistent sepals about 7 mm. long, nearly 
3 mm. broad, obtuse, 3-nerved, the upper oblong the lateral oblong-lan- 
ceolate, slightly oblique, prolonged at the base into a short gibbous 
adnate spur ; petals oblong, obtuse, often somewhat oblique, 3-nerved, a 
little shorter than the sepals; labellum 6 to 7 mm. long, yellowish white, 
dotted with purple, short-unguiculate, 3-lobed, 3-nerved from the base, 
lateral lobes short, somewhat falcate, obtuse, rounded or sometimes emar- 
ginate, the median lobe obovate-cuneate, subtruncate or retuse, entire, 
occasionally irregularly crenate, bilamellate at the base on either side of 
the midnerve, between the lateral sinuses, rather densely papillate on the 
upper surface, 5-nerved from the branching of the two lateral nerves just 
above the sinus on either side: clinandrium somewhat arched, about 5 
mm. long: capsule oblong-obovoid, 12 to 17 mm. long, reflexed. A 
Species as stated by Lindley “very like C. multiflora,” but differing in 
the lobing of the lip, the papillate character, and the venation of the 
Same, as well as the shorter Jamelle. 
Corallorhiza Pringlei. Glabrous throughout, aphyllous: stems 
slender, 1 to 3.5 dm. high, more or less scaly-bulbous at the base ; cau- 
dex provided with 1 to 3 sheathing bracts: racemes rather few-flowered ; 
floral bracts minute, shorter than the pedicels, the latter 2 to 3 mm. in 
length : flowers small, 5 to8 mm. in breadth when fully expanded ; sepals 
oblong-lanceolate, obtuse, inconspicuously 3-nerved, 3 to 4 mm. long, 
about 1 mm. broad, exceeding in length the obtuse slightly broader 
lateral petals, both sepals and lateral petals marked with a semi-translu- 
cent oblong punctation ; lip white variegated with purple, ovate-rotund or 
Sometimes slightly obovate-rotund, narrowed at the base into a short 
claw, strongly emarginate at the apex, with an irregular crenate margin, 
“nerved, bearing two somewhat diverging lamelle about one third dis- 
‘ant from the base; clinandrum short, thick, about 2 mm. long: capsule 
oblong-elliptic, 7 mm. long, reflexed on slender pedicels. — Collected by 
C. G. Pringle on shaded banks, Las Sedas, Oaxaca, altitude 2000 m., 1 
November, 1894, no. 5804; and on the Sierra de San Felipe, altitude 
2600 m., 13 December, 1895, no. 6295. 
Distributed in 1895 as C. Mexicana, Lindl., from which it is distin- 
Buished by the more slender habit, smaller flowers, and by the well 
marked characters of the lip.
