ASPLENIUM EBENOIDES IN CHESTER 

 VALLEY, PA. 



By T. Chalkley Palmer. 



The infrequency of this species will, perhaps, warrant 

 a short notice of its appearance once more within a few 

 miles of its original station. These plants were found 

 on September 8th of the present year growing on a 

 mossy ledge of the Chester Valley limestone seven miles 

 west of the Schuylkill and within the limits of Chester 

 County. The situation is shaded and the exposure is to 

 the north. The ledge is not exactly damp — it is only 

 not dry. 



One of the plants has long spore-bearing fronds and 

 has evidently survived more than one cold season. The 

 other two were younger. All were vigorous and healthy. 

 The fronds were altogether typical and the lower pinnae 

 distinctly resembled those of Asplenium platyneuron as 

 did, quite uniformly, the lower half of the rachis. The 

 plants grew within a foot or two of each other. There is 

 no intention to discuss, here, the question of hydridity. 

 However, the companion plants to these were preemi- 

 nently Asplenium platyneuron and Camptosorus.

Dr. R. J. Smith, Milpitas, Santa Clara County, Cali- 

 fornia, notes that Selaginella Bigelovii is not confined 

 entirely to Southern California. It grows quite freely 

 in Alum Rock Canyon, Santa Clara County, about seven 

 miles east of San Jose, at the foot of Mt. Hamilton. On 

 a very steep bank with northeast exposure are many little 

 clumps of bright green, some a yard or more across. 

 After the first rains in the fall they are very noticeable 

 while other plants are still brown.
