300 Clark: Hepaticae from the state of Washington 



and Roell's list of 1893,"^ 23 species, no fewer than 19 being 

 additions to Underwood's list. Howe has since reported three 

 more species, Stephani two, and C. Muller, of Freiburg, two, so 

 that 42 species in all have been definitely reported from the state. 

 As noted above, this number has been considerably more than 

 doubled by recent investigations. 



The present paper makes no attempt to give a complete ac- 

 count of the species known from the state. It simply calls atten- 

 tion to nine species which are of more than passing interest. 

 These include one species new to science and a new variety of a 

 recently published Scapania, Of the remaining species noted four 

 are new to North America and three to the United States, although 

 previously reported from the Canadian provinces.

A. Lindenbergiatta is one of the larger species of the genus. 

 As Howef clearly shows, it agrees in this respect and also in 

 general habit with A, californica (Hampe) Underw., which is still 

 known from California only. The two species agree also in 

 developing their inflorescences either on the main thallus or on
