Cephalozia patulifolia Steph. Bull. Herb. Boissier II. 8: 509 



This species was based on a specimen collected in California 

 by Bolander, no more definite locality being mentioned in the 

 published descriptions. Through the kindness of Mr. Maxon 

 the writer has had the privilege of studying Bolander's Cepha- 

 loziellse in the U. S. National Herbarium but has found 

 nothing that agrees with Stephani's or Douin's account. 

 According to the latter writer C. patulifolia agrees with C. 

 papulosa in having rough leaves and underleaves but differs 

 in its autoicous inflorescence. Stephani quotes Howe's var. 

 scabra as a possible synonym of C. patulifolia but Douin cites 

 it definitely under C. papulosa. 



35. Cephalozia Turned (Hook.) Lindb. (p. 129) 



This species is a representative of the genus Prionolobus 

 and may be known as P. turneri (Hook.) Schiffn. 



36. Scapania heterophylla M. A. Howe (p. 155) 



This interesting Scapania is still known only from the type 

 locality, Sisson, Siskiyou County, where it was collected on 

 submerged stones in a mountain stream by Howe in 1894. 

 Since its description by Howe it has been studied by Miiller, 33 

 by Stephani 34 and by Warnstorf. 35 Miiller admitted its validity 

 but recognized its close relationship to 5". undulata (L.) 

 Dumort. Stephani regarded it as "ganz deformiert" and sug- 

 gested that it might perhaps be referable to some other species 

 of the genus, without attempting to settle the matter definitely. 

 Warnstorf went still further and reduced it to varietal rank 

 under S. undulata, its name thus becoming S. undulata var. 

 heterophylla (M. A. Howe) Warnst. In his opinion the unin- 

 jured leaves at the tips of the stems and branches are quite 

 indistinguishable from those of S. undulata, and for this
