9. LIMNORCHIS Rydb. Boe orcuis. 
Erect herbaceous perennials, with succulent greenish stems arising from elongated 
rootlike tubers and bearing slender, more or less crowded spikes of inconspicuous 
greenish or white flowers, 
The plants occur in cool, moist situations in shaded thickets in rich soil. They have 
usually been referred to the genus Habenaria and are so treated in the latest revision 
of the genus.' We prefer the treatment of Doctor Rydberg,? which is followed here 
so far as it relates to New Mexican species. 
KEY TO THE SPECIES, 
Leaves short, 3 to 7 cm. long, the lowest usually largest......... 1, L. brevifolia. 
Leaves much longer, 8 to 20 cm, long, the lowest shorter than 
thos? along the middle of the stem. 
Flowers white or nearly so; spur and lip various. 
Lip linear, not at all dilated at the base, 8 mm. long; 
spur over 10 mm. long; spike long, lax, slender... 4. L. sparsiflora.
