I04 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 



Stigma without appendages, and widely diverging anther-cells with 

 small beak-like processes at the base. 



L. orbiciilata grows in rich woods, at a low altitude. 



Montana: Stillwater Lake, 1892, C. W. Helmich; Flathead 

 Lake, 1883, Canby,ji2. 



Lysiella. 



Small plant with a short rootstock and thick root fibers. Stem 

 scapose, naked, with a single obovate leaf at the base. Flowers 

 greenish yellow. Upper sepal round-ovate, erect, surrounding the 

 broad column ; lateral sepals reflexed-spreading. Petals lanceolate, 

 smaller. Lip entire, linear-lanceolate, deflexed. Spur slightly 

 curved, shorter than the arcuate ovary. Beak of stigma not ap- 

 pendaged. Anther-cells widely diverging, wholl}^ adnate, arcuate. 

 Pod obovoid. 



Apparently a monotypic genus, mainly of North America, col- 

 lected at one station in northern Norway. It is nearest related to 

 JLys/'as, differing in the single basal leaf and the structure of the 

 flower. Name a diminutive of Lysias.

Limnorchis. 



Leafy plants with thick fleshy roots, or elongated conic undi- 

 vided tubers, and small greenish or whitish flowers in a long spike. 

 Sepals and petals free and spreading, several-nerved. Lip entire. 

 Beak of the stigma without appendages. Anther-cells nearly par- 

 allel, wholly adnate. Gland naked. Pollinia granular, with cau- 

 dicula at the base. 



A North American genus of about a dozen species, differing from 

 Lysias in the many stem-leaves, the parallel anther-cells, lack of 

 processes at their bases, and a somewhat different structure of the 

 flow^er. 

 Limnorchis hyperborea (L.); Orchis hyfcrborca L. Mant. 121; 



Habcnaria hyperborea R. Br. ; Ait. Hort. Kew. Ed. 2,5: 193

In bogs and wet meadows up to an altitude of 2500 m. The fol- 

 lowing specimens have been doubtfully referred here, differing from 

 the eastern form in the somewhat longer spur :
