Mr. Ames refers a specimen collected on the Pecos River, August 6, 1898 (G. E. 
Coghill 147), to L. dilatata, Doctor Rydberg cites a specimen of L, ensifolia from 
Silver City, collected in 1880 by E, L. Greene. We have seen neither of these speci- 
mens, J. dilatata is a northeastern species, ranging only as far west as Nebraska, 
excluding the specimen mentioned. ZL. ensifolia is closely related to L, sparsifolia, 
and is reported from the same region; it differs in having a shorter and denser spike, 
the upper sepals larger, and the bracts shorter and broader; its leaves are noticeably 
different in shape in material we have seen.
