L. borealis is common from Alaska to Washington and Colorado. Type : "Unalaschca," Fig. II. 11. Limnorchis foliosa sp. nov. Stem stout and very leafy, about 3 dm. high : leaves linear- lanceolate, attenuate, i — dm. long: spike short and dense, less than I dm. long; bracts linear- lanceolate, attenuate, about three times as long as the flowers : these about 15 mm. long, white : upper sepal broadly linear, obtuse, about 6 mm. long ; lateral ones narrowly lanceolate, about 9 mm. : petals narrowly linear-lanceolate, attenu- ate ; lip about 10 mm. with an oval base and an almost linear lower half, obtuse : spur about the length of the lip,filiform, not at all clavate. (Fig. II.) This species has the habit o{ Pcnilaria flava and Cocloglossuui bractcatimi, but the flower is of the typical LiinnorcJns t}^pe and places it nearest to L. dilatata. The flowers, however, are larger and the lip less rhomboid. Al.\ska : Nagai, 1871-2, M. \V. Harrington (Ball's Fxplora- tion ; type in the Columbia herb.). 12. LiMXOKCHis (Pursh) Rydb.; Britton, Man.
