ryum argcntcum and Funaria hygromctrica. As in the case of 

 Drummond's specimens the antheridial parent is unknown, but 

 was probably Physcomitrium turbinatiim ; it scarcely seems possible 

 tnat it could have been Funaria. The specimens agree in every 

 way and show various evidences of inheritance from each parent. 

 Un most of the plants, typical immersed capsules of Aphanorhegma 

 occur together with either one exserted, long-pedicelled capsule of 



hyscomitrium or with two smaller immersed capsules more closely 

 related to Physcomitrium than to Aphanorhegma. As in Drum- 

 mond's specimens, the apical lid with a clearly differentiated 



order, the shallow spore-sac, and especially the different cell- 

 structure of the walls and the less developed spores, clearly dis- 

 •nguish the hybrid sporophytes from typical Aphanorhegma. 

 Discussion followed regarding hybrid ferns, and respectin^ 



splenmm platyneuron and A. ebenoides. In answer to questions 

 Y Dr. Rusby, Dr. Underwood said that where both species grow 

 ogether in Alabama, he finds A. ebenoides growing beneath cliffs, 



platyneuron in different situations about the edges of
