Polypodium speluncae L. was first by Moore identified 

 with Davallia polypodiodes Hk., which species is since 

 commonly called Microlepia speluncae. Whether Moore 

 was correct in that identification is unfortunately not 

 quite sure. According to B. D. Jackson, 1 no specimen of 

 P. spelunca is to be found in the Linnaean Herbarium. 

 Summary: The combination Dryopteris speluncae (L.) 

 Und. is not well founded, and it ought not to have been 

 published. The Bermuda plant is probably D. ampla, 

 as given in my forthcoming revision of the American de- 

 compound species of Dryopteris. Polypodium speluncae 

 L. may be the species generally called Microlepia speluncae 

 (L.) Moore, but this is not proved, certainly it is not D. 

 ampla.

Wayside ferns of the Dolomites 



C. A. WEATHERBY 



The route through the Dolomite region, which is usu- 

 ally followed by travelers arriving from the south, runs 

 from Belluno in northeastern Italy, where the railway 

 stops, by way of Cortina and the new " Dolomites Road, " 

 to Bozen in the valley of the Adige. Geologically speak- 

 ing, it hardly touches the real Dolomites at all. For three- 

 quarters of its length, it traverses a belt of ''more or less 

 pure' 7 Triassic limestone which wholly lacks the high 

 percentage of magnesium characteristic of true dolomite. 

 For the latter part of the way, on the descent through 

 the Eggenthal to Bozen, the prevailing rock is a rather 

 close-grained, purplish porphyry, in appearance very lik<
