1. H. aphyllus Raf. Stem 3 to 6 din. high, beset with purplish scales, the lower 
sheathing: flowers racemed, bracteate, brownish-purple, 12 to 16mm, long. (Bletia 
aphylla Nutt.)—Rich woods, extending from the Gulf States through Texas into

4. GYROSTACHYS Pers. (LADIES’ TRESSEs. ) 
Leafy plants, with clustered-tuberous roots, stems leaty at base, 
small white flowers in a regular or one-sided or spirally twisted spike, 
nearly equal sepals and petals (lateral sepals diverging and dilated at 
base, upper connivent with the petals), the clawed concave lip fur- 
nished with 2 callosities near the base and involute around the lower 
part of the column, ovate beaked stigmas, anthers attached to back 
of column, and 2 obovate 2-cleft powdery pollen-masses fixed to a 
common gland of the stigma, (Sptranthes Richard.) 
1. G. cernua (L.) Kuntze. Stem leafy below and leafy-bracted above (1.5 to 4 dm, 
high): leaves linear-lanceolate, the lowest elongated (1 to 3 dm, long): spike cylin- 
drical, rather dense (5 to 12 em. long) and with white fragrant flowers, pubescent or 
nearly smooth: perianth horizontal or recurving (8 to 10 mm. long); the lower 
sepals not upturned or connivent with the upper; lip oblong, longer than the 
Sepals, contracted above the middle, wavy at the recurved obtuse apex, the callosi- 
ties at the base prominent, nipple-shaped, somewhat hairy: glands of the stigma 
linear, in a long and very slender beak. (Ophrys cernua L. Spiranthes cernua Rich- 
ard,)— From Hockley to the Trinity. 
2. G. gracilis (Bigelow) Kuntze. Stem very slender (1.5 to3 dm, high), smooth 
throughout, scape-like: lowest leaves lanceolate or elliptical (2.5 to 5 em. long), 
spreading: spike very slender, with the minute flowers (2 to4 mim, long) on one side 
of the rhachis or sparingly spiral, smooth: lip finely crenulate on the margins, 
recurved and acute at apex, with2 nippie-shaped callosities at base: anthers 4-cleft. 
(Spiranthes gracilis Bigelow. )—From Hockley to the Trinity. 
3. G. cinnabarina. (Llave) Kuntze. Stem scape-like, pilose: radical leaves obloug- 
lanceolate, acute: spike large, conical-thyrsoid and compact, with lanceolate dull 
olive-green bracts shorter than the pilose flowers, which are vermillion red exter- 
nally and bright yellow within: sepals and petals linear-lanceolate, acuminate, 
spreading at apex: lip glabrons, narrowed and channeled at base. (Neotlia cinna- 
barina Llave. Stenorrhynchus cinnabarinus Lindl, Spiranthes cinnabarina Watson. )— 
A very showy Mexican species, found in one locality in the Chisos mountains. 
(Havard). 
5. PERAMIUM Salish. 
Stems leafy, from creeping rootstocks, with racemed flowers, con- 
spicuous bracts, nearly equal sepals and petals, the free lip narrowly 
constricted at the middle, short and erect column, sessile anthers 
behind the broad truncate stigma, the coarsely granular pollen-masses 
becoming attached to the gland capping the small rounded beak of the 
stigma, and ovaries at right angles to the stem. (pitpactis Haller.) 
1. P. giganteum (Dougl.) Stem 3 to 12 dm. high, nearly smooth: leaves from 
ovate (below) to narrowly lanceolate (above), somewhat scabrous on the veins 
beneath: racemes pubescent: flowers greenish, strongly veined with purple: saccate 
base of lip with erect wing-like margins, strongly nerved and the nerves callous- 
tuberculate near the base. (pipactis gigantea Doug].)—Extending into western 
Texas from the west.
