have named Pteris aquiUna pseud o caudata. It is simply 

 a form with elongated narrow pinnules, the terminal one 

 being unusually lengthened. It may occur wherever the 

 insolation and small water supply make a reduced leaf 

 surface desirable. For this reason it is most common in 



PTERIS AQUILINA PSEUDOCAUDATA 



the southern states, where it is often the dominant fern, 

 though it may occur northward in the sandy wastes near 

 the coast as far as Massachusetts. The specimen illus- 

 trated was sent me by W. C. Dukes of Mobile, Ala., and 

 represents a not unusual form of the frond in which the 

 terminal pinnule may have a few projections or lobes 

 upon it. The illustration is of two pinnae from the base 

 of the frond. — Willard A T . Clute. 



The Water Clover. — There never can be rules for 

 the making of common names. The common people will 

 call the plants what they please. In the Garden Maga- 

 zine we find Marsilia quadrifolia called water clover, a 

 name that is quite descriptive, although Marsilia does not 

 belong to the same grand division of the plant world that 

 clovers do.
