pec, in the State of Oaxaca, altitude 2000 m., 1 June, 1895, no. 545; 
also by C. Conzatti near the city of Oaxaca, altitude 1550 m., 17 May, 
1896, no. 146. 
This species has been hitherto attributed to Northern Mexico and 
Texas. 
Furcra&a Bepineuausi, Koch. Wochenschr. 1863, 233 ; Morr. Belg. 
Hort. xiii. 327, with fig.; Baker, Handb. Amaryll. 203, & Bot. Mag. 
te 0 this species may be referred Pringle’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. Larly.in the present season Mr. Pringle was successful 
in securing flowering specimens, which proved beyond a doubt that the 
affinity of the plant is with the genus Furcrea, 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 gibbosity: 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 illine lobulo obtuso aucto.” ; 
CoRALLORHIZA MEXICANA, Lindl. Gen. & Sp. Orch. 534. Spectr 
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. Gonzélez, 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 1 
question.
