GREENMAN. — PHANEROGAMS. 475 



Plant glabrous throughout, aphyllous : stems from an ascending 

 rhizome, 3 to 7 dm, high, purplish, provided with 2 to 4 sheathing 

 obtuse or acutish somewhat scarious nerved bracts : racemes many- 

 flowered ; rhachis subangulate ; floral bracts small, scarious : perianth 

 1.5 cm. 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 ; labellura 6 to 7 mm. long, yellowish white, 

 dotted with purple, sliort-unguiculate, 3-lobed, 3-)ierved 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, o-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. multijiora" but differing in 

 the lobing of the lip, the papillate character, and the venation of the 

 same, as well as the shorter lamellae. 



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 to 8 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, 

 3-5-nerved, bearing two somewhat diverging lamellae about one third dis- 

 tant 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 G. Mexicana, Lindl., from which it is distin- 

 guished by the more slender habit, smaller flowers, and by the well 

 marked characters of the lip.
