In mountain woods from Mendocino and JLiiiposa Counties to the British Boundary, and east- 

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

 remarkably from the other species in the less saccate lij) and in tlie acuminate instead of ])lunt 

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

 a Spirantlus. 



7. LISTERA, 1!. Brown. TwAvnLADi:. 

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

 the sepals. Hat and dilated, mure or less deeply bilid. 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 fibroiis 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 nortliern liemispherc, scarcely distinguished from 

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

 Atlantic States, the rest belonging to the Old World. 



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

 across the continent ; in damp cold woods. 



b. conDAT.\, 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, 'J-clcft, 'J-toothed at Imsc; ctdumu very short. Belonging also to Northern Euiope.
