from Chiapas have all the pinnae deflexed." That is the case with 

 Prof. J. G. Lemmon's specimens from the Huachuca Mts., Ariz. 

 I have not seen either Kunze's description or his specimens, but 

 am inclined to believe that we have two species in the United 

 States, viz., A. resiliens Kze., in the west, and A. parvulum M. 

 & G., in the east. 



THE FERN FLORA OF WASHINGTON. 



By J. B. Fuctt. 



The State of Washington has not been as thoroughly explor- 

 ed as have the older States in the East. Much has been done, but 

 much remains to be done. This is especially true in the moun- 

 tain region, where vast areas still await the advent of the botan- 

 ical explorer. No complete list of ferns and their allies of this 

 State can be made for many years to come, until the hidden 

 recesses of mountain, lake, and canon have been thoroughly 

 explored and their secrets revealed. 



This State has a great diversity of soil and climate. It may 

 be divided into three topographical regions. The climate of 

 each being modified by local conditions. Western Washington, 

 or that region lying west of the Cascade Mountains, has an 

 average rainfall of about 65J/2 inches. The northwestern part 

 is traversed by the Olympic Mountains, on whose western slopes 

 there is an average rainfall of about 92 inches. Here the ferns 

 grow luxuriantly in the mossy woods, the species most abundant 

 and conspicuous being the following: Maiden hair, sword fern, 

 deer fern, brake, western polypody or licorice fern {P. falca- 

 tum), spreading wood fern and Athyrium cyclosorum with its 

 varieties, especially latifoliutn. On the storm-swept peaks at 

 an altitude of about 5.000-6,000 feet are the following: The 

 holly fern, mountain polypody (P. hesperium), dwarf spleen- 

 wort, fragile fern (Cystopteris fragilis), mountain lace fern 

 (Chcilanthes gracillima) and parsley fern, or pea fern, as it 

 is popularly called with us, from its peculiar manner of fruiting. 



In the Puget Sound basin lying between the two mountain 

 regions may be found all the ferns mentioned as conspicuous 

 west of the Olympic range, to which must be added Woodwardia
