anew genus, based on the fusion of the sepals. Once I became 
aware of the characters of the true Cyclopogon, I requested the 
type from Prague, and an examination of it confirmed my 
interpretation. Cyclopogon is closest to the genus Gamosepal- 
um, but in the latter genus the column in the flowers is adnate 
dorsally to the sepals. 
It must be emphasized that the circumscription given by 
Schlechter for Cyclopogon is no longer tenable. Fortunately, 
for Schlechter’s concept the generic name, Beadlea Small is 
available. Appropriate transfers are being made in the new 
generic revision of the Spiranthinae by Dr. Pabst and me. 
The following amplified descriptions are prepared from the 
type-material and from the additional material at hand. The 
genus is monotypic. 
Sepals similar, basally connate into a cylindric tube, above 
free. Petals connivent with dorsal sepal, basally for a short 
distance adnate to column. Lip broadly unguiculate, sagittate- 
auriculate, the claw adnate to sepaline tube. Column free, 
elongate, slender, cylindric, pubescent in front, basally pro- 
duced into a short, somewhat descending foot; stigmata 2, 
approximately touching each other; rostellum elongate, ligu- 
late, truncate or obscurely excised; anther in the descending 
clinandrium dorsal, erect, 2-celled. Ovary sessile. Terrestrial 
plants with fleshy, fasciculate, villose roots. Leaves basal, 
many, petiolate. Scape slender, several-sheathed, spicate 
above. Bracts linear-setaceous. Flowers small.
