456 A. W. Evans — Haioaiian Hepaticm of the Tribe Juhuloideoe. 



In addition to the Lejeuneese described and noted in this papei', 

 the two following species, both of which are rather widely distrib- 

 uted in tropical America, are accredited to the Hawaiian Islands: 

 Prionolejeunea microdonta (Gottsche) Steph. and Stictolejeunea 

 squamata (Willd.) Schiffn. I have looked in vain for Hawaiian 

 specimens of these plants in the herbaria at Kew and Berlin, and 

 Herr Stephani makes no mention of such specimens in his paper on 

 the Lejeunecp in the Lindenberg Herbarium at Vienna. I have 

 therefore omitted them, as it is probable that they were listed on 

 incorrect determinations.
