136 ORCHIDACE.E. Goody era. 



base, petioled, usually white-reticulate. Rootstock creeping, Avitli fibrous fleshy 



rootlets. 



A dozen or more species are widely distributed around the globe, mostly in the tropics. The 

 two other North American species, one of them common in N. Europe and Asia, are not found 

 west of the Kocky Mouiitain.s. 



1. Gr. Menziesii, Li mil. Scape aud inflorescence pubescent, 6 to 15 inches 

 high : leaves smootii, ovate-oblong to oblong-lanceolate, acute, 2 or 3 inches long, 

 narrowed into a short petiole, usually somewhat reticulated with light greenish 

 markings : spike many-flowered, rather dense, secund : bracts ovate-lanceolate, 

 equalling the ovary : perianth white, i)uberulent, 2 to 4 lines long ; lip strongly 

 concave and erect, narrowing above into the slightly spreading summit : column 

 short and straight : anther acuminate : gland and bifid beak very narrow and 

 elongated (a line long or more) : capsule ovate-oblong, very nearly sessile, 4 lines 

 long. — Orch. 492. Spiranthes decipiens, Hook. Fl. Bor.-Am. ii. 203, t. 204. 



In mountain woods from Ihmdocino and Mariposa Counties to the British Boundary, and east- 

 ward along the northern border to Western New York : August and September. Differing 

 remarkably from the other species in the less saccate lip and in the acuminate instead of blunt 

 anther, as well as in the elongated beak of the stigma, in these respects more nearly resembling 

 a Sjnranth^s. 



7. LISTERA, h. Brown. Twayblade. 

 Perianth spreading or reflexed : sepals and petals similar : lip free, longer than 

 the sepals, flat and dilated, more or less deeply bifid. Column free and naked, 

 bearing the ovate anther at the back of the summit. Pollen-masses 2, powdery, 

 united to a very minute gland upon the rounded and entire beak of the stigma. — 

 Stems low, from fibrous and creeping roots, and with a pair of broad sessile oppo- 

 site leaves in the middle ; flowers small and greenish, in a loose raceme. 



A genus of 5 or 6 species belonging to the northern hemisphere, scarcely distinguished from 

 Neottia but by its herbaceous foliage. Besides the following another species is found in the S. 

 Atlantic States, t}ie rest belonging to the Old World. 



1. L. convallarioides, Nutt. Stem slender, 3 inches to a foot high, naked 

 excepting one or two sheaths at base and the pair of orbicular or ovate acutish 

 leaves (1 to 3 inches long) just below the raceme : inflorescence pubescent; flowers 

 6 to 20, purplish ; bracts acute, shorter than the slender pedicels : sepals and petals 

 linear, 2 or 3 lines long ; lip oblong-ovate and cuneate, 2 to 5 lines long, emar- 

 ginate or 2-lobed, with a small tooth on each side near the base : column slender, a 

 line long : capsule erect, ovate-oblong, 3 lines long and about equalling the pedicel.

In the Sierra Nevada from the South Fork of the Joaquin {Muir) northward to Alaska, and 

 across the continent ; in damp cold woods. 



L. coitDATA, R. Brown, collected in Oregon and Washington Territory {Hall, Lyall) and of 

 like range north and eastward, should be found in California. The leaves are smaller, triangular- 

 ovate and somewhat cordate ; flowers minute, on short pedicels in a smooth raceme ; sepals ovate ; 

 lip linear, 2-cleft, 2-toothed at base ; column very short. Belonging also to Northern Europe. 



8. EPIPACTIS, Huller. 

 Perianth spreading, the sepals and petals nearly equal : lip free, deeply concave 

 at base, without callosities, narrowly constricted and somewhat jointed in the mid- 

 dle, the upper portion dilated and petaloid. Column short (equalling the anther), 

 erect. Anther sessile behind the broad truncate stigma, on a slender jointed base, 

 2-celled, obtuse : pollen-masses coarsely granular, becoming attached above to the
