Herbarium, here alluded to, represents a part of the type of S. guadran- 
gulatum, Klatt, as it answers perfectly to the description. With it, 
moreover, Mr. Pringle’s specimens are an excellent match. The species 
seems well characterized by the linear grass-like leaves, and the pyri- 
form glabrous fruit, fully twice longer than in S. angustifolium, Mill., 
and its related forms. 
SISYRINCHIUM TENUIFOLIUM, Humb. & Bonpl., var. Seatoni. Stems 
about 1 dm. high, much-branched, glabrous: leaves equalling or exceed- 
ing the inflorescence, slender, subfiliform : capsule pubescent. — MExIco.

r.). 
The variety Seatont differs from the species chiefly in the lower 
stature, and in the filiform character of the leaves. 
Habenaria oreophila. Glabrous throughout: stem erect, leafy, 
7 to 8 dm. high: leaves oblong-lanceolate, 1 to 1.5 dm. long, 3 to 3.5 cm. 
broad, apiculate-acute, entire, membranous; the lowermost leaves re- 
duced to mere sheaths, the uppermost gradually smaller: inflorescence 
a terminal elongated loose 2 to 3 dm. long raceme; bracts subfolia- 
ceous, lanceolate-acuminate, about equalling the ovary: upper sepal 
ovate, cucullate, 8 mm. long, 3-nerved; lateral sepals oblong-lanceolate, 
slightly oblique, obtuse, 3-nerved: lateral petals deeply 2-parted ; the 
upper division lanceolate, upwardly arched, shorter than and coherent 
with the upper sepal; lower division bent downward, linear-attenuate 
and somewhat coiled at the tip: labellum deeply 3-parted; the middle 
lobe ligulate, slightly thickened, 11 to 13 mm. long, obtuse ; lateral 
divisions linear-attenuate, 2.5 cm. long, more or less spirally coiled at 
the free ends: spur clavate, free, 4 to 4.5 cm. long: column bearing 
fleshy oblong appendages at the base: ovary narrowly winged. — 
Mexico. State of Guerrero: mountains near Iguala, 15 September, 
1900, O. G. Pringle, no. 9248 (hb. Gr.). 
The affinity of this species is with Habenaria jaliscana, Watson, and 
H. leucecapensis, Fernald. From the former it is readily distinguished 
by the height, the longer leaves, the longer spur, and by the entire 
absence of the falcate character of the lateral divisions of the labellum; 
and from the latter it differs in having much longer and narrower leaves.
