found by Mr. M^'Rae about Valparaiso are more slender in all 

 their parts than those from Cumbre, which is a pass on the 

 Chilian side of the Cordilleras.

This appears to be very distinct from any found by Mr. M<^Rae. 

 It is nearly related to C hletioideSy which it seems to emulate 

 in the size of the flowers.

 Stem about a foot and a half high. Leaves erect, oblong-lanceolate, 

 somewhat obtuse, gradually changing to long, membranous, acumi- 

 nate, sheathing squamae. Spike about five inches long, eight or ten 

 flowered. Bractecs membranous, acuminate, neai'ly as long as the 

 upper sepals. Flowers ringent. Upper sepal lanceolate acute, inner 

 erect, rather shorter, obtuse ; lower sepals three times as long as the 

 upper ones^ ovate-acuminate, spreading, membranous, finely fringed 

 beyond the middle with long delicate filiform processes which arise 

 from the margin. Labellum ovate- acuminate, cucullate at base, about 

 one-third the length of the lower sepals, like which it is also bordered 

 with a fringe of long filiform cilise. Colu?nna erect, half the length 

 of the upper sepals. 

 Two specimens only of this noble species, one in flower, the 

 other in bud, were discovered by Mr. M°Rae in the grassy 

 pastures about the hot-baths of Colina, a small village on the 

 skirts of the plain which surrounds the town of Santiago. The 

 fine fringe that borders the lower sepals and the labellum caM
