7 lines), moderately dilated toward the end, round-truncate or slightly 

 emargiuate and apiculate, the 3 laminae very broad at the base of the 

 middle lobe and again near the summit, ending abruptly. Rio Blanco, 

 on grassy hillsides ; August. (337.) — Color a " beautiful dark salmon 

 and red." 



Bletia ? Of the B. verecunda group, but low and slender, 



the narrow leaves a span long: flowers few (6 or 7 lines long), nar- 

 rowed and scarcely gibbous at base, " cream-color within, amber with- 

 out"; lateral sepals subfalcate, acute, equalling the ligulate obtuse 

 petals ; lip flabelliforra, the lateral lobes parallel with the broad middle 

 one, which is not produced and but slightly broadened upward, crispate, 

 as also the 3 broad laminae. Rio Blanco, on rocky hillsides ; August. 

 (336.) 



Spiranthes graminea, Lindl. Rio Blanco, in damp shade ; Oc- 

 tober. (7-47.) — Resembling the original 224 Hartweg except that 

 the lower sheaths appear to be more completely closed ; hardly the 

 species of the Atlantic States so called. 



Spiranthes aurantiaca, Benth. & Hook. Rio Blanco, in deep 

 barrancas; September. (581, but written 481 in the Cambridge set.) 



— Flowers and bracts orange-color ; the foliage blackens as soon as 

 placed in paper. 



Habenaria spathacea, Rich. & Gal. Stem from a soft tuberous 

 root, over a foot high, covered with sheathing spathe-like leaves (3 or 

 4 inches long) : flowers 2 or 3, lemon-color, on long pedicels within 

 large dilated fuliaceous bracts ; sepals broad, 5 lines long ; petals 2- 

 parted, the upper division twice broader and subfalcate lip subequally 

 3-cleft nearly to the base, 6 or 8 lines long. Rio Blanco, on grassy 

 hillsides; September. (342.) — A peculiar species which can scarcely 

 be mistaken. 



Habenaria Jaliscana. A foot high from a small tuberous root, 

 stout and leafy : leaves lanceolate, or the lower ovate, acute, sheath- 

 ing, 3 inches long or less : raceme short and open, with large foliaceous 

 bracts : sepals ovate, acute, nearly equal (4 lines long), the lateral sub- 

 falcate ; petals 2-parted and lip 3-parted, the divisions strongly falcate 

 excepting the ligulate-spatulate obtuse middle lobe of the lip, its longer 

 (6 lines) lateral lobes and the lower lobes of the petals approximate 

 on each side, linear, acuminate, the upper petal-lobes contiguous to 

 the upper sepal ; spur narrowly clavate, 12 to 15 lines long: column 

 with fleshy oblong appendages at base \\ lines long; stigmatic pro- 

 cesses \\ lines long. Rio Blanco, in moist bottoms; August. (343.) 



— Flowers greenish yellow. This (as the following) may be some
