TREASURE TROVE. 



By A. B. Klugh. 



In the southeast corner of Wellington County, Ontario, in 

 the midst of a mixed bush, stands a piece of rock some fifty yards 

 long by twenty-five feet in height. From a little distance it ap- 

 pears to be a very ordinary piece of rock, but on the first near 

 approach a fern student feels a sudden desire to shout, for there 

 in the mossy recesses he sees Pellaea gracilis, on the ledges Camp- 

 tosorus rhizophyllus, at the edge and on some of the upper ledges 

 Polypodium vulgare, and scattered all over the whole rock Cystop- 

 teris bulbifera. 



The existence, in a flourishing condition, of these ferns on a 

 rock by no means damp, and of so small extent is interesting, if 

 not unique. It might be mentioned that this is one of the two 

 stations known in the country for Pellaea gracilis, that Camp- 

 tosorus rhizophyllus is fairly common and widely distributed, 

 that Polypodium vulgare is scarce, being absent from all our big 

 masses of rock, and that Cystopteris bulbifera is our most abun- 

 dant fern, growing in all our damp woods and on all cliffs and 

 rocks. 



Another interesting little spot is to be found in a sphagnum 

 swamp near Guelph, as here within a radius of four yards I found 

 • Botrychium Virginianum, Osmunda cinnamomea, Adiantum peda- 

 t it Athyrium Ulix-foemina, Phegopteris dryopteris, Cystopteris 

 bulbifera, Nephrodium thelypteris, N. cristatum, N. marginale, 

 N. spinulosum, and N. boottii, and for the last named species it is 

 the only station known, it being very rare in this locality.

ASPLENIUM EBENOIDES. 



During a week's stay in eastern Pennsylvania, I made a botan- 

 ical excursion with the express purpose of finding Asplenia m 

 ebenoides in a spot where Asplcnium cbeneum and Camptosorus 

 rhizophyllus are growing in company. The result was two plants 

 not only of ebenoides, but that rare form of it which has rounded 

 instead of lanceolate pinnules. I report the occurrence of these as 

 additional evidence in favor of the theory of hybridity. — James
