11. Gyrostachys ochroleuca Rydb. Roots similar to those of G. cernua: stem 3-5 

 dm. tall, densely pubescent above : leaves various ; basal with linear blades 1-2 dm. long, 

 tapering to both ends and distinctly petioled ; lower stem-leaves similar, but mostly sessile; 

 upper stem-leaves reduced to lanceolate scales : spike densely flowered, 5-15 cm. long, 

 15-20 mm. thick, usually acute: perianth yellow-green or ochroleucous, very fragrant, 

 about 1 cm. long : bracts lanceolate or ovate-lanceolate, acuminate, the lower ones gener- 

 ally longer than the perianth : lip rounded at the apex, with straight hairy nipple-shaped 

 callosities. 



On hillsides, New Hampshire to Pennsylvania and North Carolina. Spring and summer. 



12. Gyrostachys plantaginea (Raf.) Britton. Roots clustered, coarse: stems 1-4 

 dm. tall : leaf-blades broadly linear or oblong, 5-15 cm. long, reduced to sheathing scales 

 above ; petioles shorter than the blades : spike 2-10 cm. long, 1-1.5 cm. thick : perianth 

 white, 6.5-7 mm. long: lateral sepals free, narrowly lanceolate: lateral petals somewhat 

 united with the upper sepals : lip yellow within, oblong, undulate, with a short claw ; cal- 

 losities relatively small, spreading* from the sides of the truncate base of the lip. ISpiran- 

 thes latifolia Torr.] 



In woods and on shaded banks, New Brunswick to Minnesota, North Carolina and Michigan. 

 Spring and summer. 



13. Gyrostachys odorata (Nutt. ) Kuntze. Roots clustered, coarse : stems 2-6 dm. 

 tall : leaf-blades oblong to oblong-lanceolate or sometimes narrowly linear-oblanceolate, 1-3 

 dm. long or shorter above and reduced to scales, acute ; petioles as long as the blades or 

 shorter, margined : spike 1-1.5 dm. long, 2-2.5 cm. thick : bracts acuminate, somewhat 

 shorter than the fragrant flowers or longer : perianth yellowish white : lateral sepals free, 

 like the lateral petals acute : lip nearly 1 cm. long, the base broadly oval or suborbicular, the 

 tip oblong, eroded and crisped, about as long as the base ; callosities slender, incurved, 

 each more or less pubescent at the base. 



On river banks, often in the water, Kentucky to North Carolina, Florida and Texas. Fall. 



14. Gyrostachys vernalis (Engelm. & Gray) Small. Roots several, coarse: stems 

 3-5 dm. tall, slender, scape-like : leaf-blades linear, early disappearing, those above the 

 middle of the stem reduced to sheathing scales : spike 5-12 cm. long, about 1.5 cm. thick : 

 bracts lanceolate, somewhat shorter than the flowers, acuminate : perianth white or whitish : 

 lip about as long as the sepals and lateral petals, 6-7 mm. long, constricted about the 

 middle, the base oblong, oval or rhombic-orbicular, the tip oval, suborbicular, crisped. 

 [Spiranthes vernalis Engelm. & Gray.] 



In sandy woods, Alabama to Texas. Fall. 



15. Gyrostachys constricta Small. Roots very coarse : stems 3-4 cm. tall, stout : 

 leaf-blades linear or narrowly linear-spatulate, 1-2 dm. long, acute, narrowed into mar- 

 gined petioles or those higher up on the stem reduced to sheathing scales : spike 5-10 cm. 

 long, 2-2.5 cm. thick, closely flowered : bracts lanceolate, as long as the flowers or shorter, 

 acuminate : lip 7-10 mm. long, nearly as long as the sepals and lateral petals, constricted 

 above the middle, the tip ovate or deltoid-ovate, much shorter than the base, the base ovate, 

 with 2 more or less incurved basal callosities. 



In marshes, Louisiana. Fall. 



16. Gyrostachys triloba Small. Roots several, cord-like : stems 3-5 dm. tall, 

 slender, sometimes rather weak : leaf-blades oblong or elliptic-oblong, 3-8 cm. long, acute, 

 sheathing at the base ; upper stem-leaves reduced to sheathing scales : spike 4-8 cm. long, 

 about 1.5 cm. thick : bracts lanceolate, acuminate, shorter than the flowers : lip oblong, 6 

 mm. long, about equalling the sepals and lateral petals in length, recurved and 3-lobed at 

 the tip, crisped throughout, cordate, with 2 basal callosities. 



In sand, near Fort Meyer, Florida. Winter. 



12. BEADLEA Small. 



Herbs, with short coarse fibrous roots. Stem scape-like, solitary. Leaves various : 

 those at the base of the stem normal, few ; blades broad, contracted into short petioles : 

 those on the stem reduced to sheathing scales, rather remote. Flowers in a terminal few- 

 flowered spike. Perianth inconspicuous. Sepals various, the lateral free, curved, the 

 middle one adnate to the lateral petals : lip folded around the column and adnate to it, 

 without callosities at the base. Anthers erect on the back of the column, ovoid, shorter 

 and broader than the lanceolate entire pointed stigma. Capsules ascending or spreading. 



1. Beadlea Storeri (Chapm. ) Small. Roots usually four, coarse fibers: stem 1-2 

 dm. tall, pubescent above : leaves 3-4, basal or nearly so ; blades ovate, somewhat oblique,
