pec, in the State of Oaxaca, altitude 2000 m., 1 June, 1895, no. 545; 

 also by C. Couzatti near the city of Oaxaca, altitude 1550 m., 17 May, 

 1896, no. 146. 



This species has been hitherto attributed to Nortliern Mexico aud 

 Texas. 



FuRCR^A Bedinghausii, Koch. Wocheuschr. 1863, 233 ; Morr. Belg. 

 Hort. xiii. 327, with fig. ; Baker, Haudb. Amaryll. 203, & Bot. Mag. 

 t. 7170. To this species may be referred Priugle's no. 6669, collected 

 on lava beds, Serrania de Ajusco, altitude 2600 m., 17 August, 1897, dis- 

 tributed as "Yucca Pringlei," a name given to the plant from fruiting 

 specimens only. Early in the present season Mr. Priugle was successful 

 in securing flowering specimens, which proved beyond a doubt that the 

 affinity of the plant is with the genus Furcrcea, and not with Yucca. 



Through the kindness of Mr. J. G. Baker, of the Royal Gardens, Kew, 

 Mr. Pringle's plant (notwithstanding its somewhat smaller leaves) has 

 been identified with the above species. 



Corallorhiza involuta. Aphyllous, glabrous throughout, the 

 entire plant purplish: roots coralloid : stems 1 to 2.5 dm. high, provided 

 with three sheathing obtuse bracts: racemes few-several-flowered: floral 

 bracts short: perianth purple, about 12 mm. in diameter; sepals oblong, 

 somewhat narrowed toward the apex, 6 mm. long, about one third as 

 broad, 3-nerved, the lateral sepals a little unequal at their bases forming 

 a slight gibbosit}' : petals oblong, obtuse, 3-nerved, nearly equalling the 

 sepals : labellum deep purple with a yellowish base, oblong, thickened, 

 6 mm. long, about one half as broad with an obtuse blunt almost truncate 

 apex, provided near the base with a thick cushion-like body, margins 

 strongly involute : clinandrium somewhat arched, about 3 mm. long. — 

 Collected by C. G. Pringle under oaks on the summit of Sierra de San 

 Felipe, Oxaca, altitude 2925 m., 16 June, 1894, no. 5874. 



This may possibly prove to be the same as the C. bulbosa, Rich. & 

 Gal., but the base of the plant is not bulbous, and there is no correspond- 

 ence with the character " hinc et illinc lobulo obtuso aucto." 



Corallorhiza mexicana, Lindl. Gen. & Sp. Orch. 534. Speci- 

 mens collected by Mr. C. G. Pringle on the Sierra de San Felipe, 

 Oaxaca, altitude 2750-3000 m., June, 1894, no. 4690, also in the same 

 locality by C. Conzatti and V. Gonzalez, 12 September, 1897, no. 

 461, are referred doubtfully to the above species. In view of the very 

 meagre descriptions of the Mexican species of this genus, it seems 

 advisable to append the following description of the specimens in 

 question.
