Porella platyphylla (L.) Lindb. Concerning the material reported by the 

 writer under this name Dr. Evans writes: "I have recently been studying the 

 specimens of Porella from New Mexico and it seems to me that they hardly 

 represent the true P. platyphylla. In all probability they ought to be referred 

 to P. platyphylloidea instead. Unfortunately the most important distinction 

 between these species is found in the elaters and none of the New Mexican 

 specimens which I have seen have mature capsules. The gametophytic char- 

 acters, however, correspond better with those of P. platyphylloidea.^' Dr. Evans 

 states that he has material of this plant collected on the West Fork of the Gila 

 River, New Mexico, in August, 1903, by O. B. Metcalfe (No. 490), and that 

 specimens collected by Fendler were distributed by Austin (as Madotheca rivu- 

 laris var.) as No. gic of his Hepaticae Boreali-Americanae. 



Frullania mexicana Lindenb. Reported from New Mexico by Evans, ^ the 

 specimens collected on an oak at Cloudcroft, August, 1899, by Wooton. This 

 collection was reported earlier as F. inflata Gottsche.^ 



Frullania Wrightii Austin, Bull. Torrey Club 3: 15. 1872. The type is 

 said to have been collected in New Mexico by Charles Wright in " 1861 " (doubt- 

 less 185 1 ). Many plants have been referred erroneously to New Mexico as the 

 result of the misleading labels of Wright's ccllections of 1849-52, the specific name 

 " neomexicana," for instance, having been applied to several plants not known 

 to grow in the State. Although many of Wright's specimens were collected in 

 Texas, Arizona, Chihuahua, and Sonora, all were distributed with labels implying 

 or definitely stating that they came from New Mexico, a decidedly loose use of 

 the name, even for that time. The chances are favorable that this hepatic came 

 from the vicinity of Santa Rita, a locality at which Wright spent much time and 

 one better suited to the growth of hepatics than most of the regions he explored. 

 Dr. Evans states that Frullania Wrightii is a doubtful species and may be only 

 a form of F. riparia. 



The writer is under obligations to Dr. Evans for the data cited above. It 

 thus appears that five species are to be added to the seven reported previously^ 

 Very probably still others may be found by a careful search of literature.
