36 POLYPODIUM CALIFORNICUM. CALIFORNIAN P()LYPODY. 



parent veins as seen when held up to the Hght. These veins 

 are club-shaped, or thickened upwards at the termination, a 

 point that does not seem to have attracted the attention of 

 describers, though as to the mere frond differences in the 

 opacity of the various forms have been commented on. 



Kaulfuss in the work from which we have translated the 

 description says it is " similar \.o Polypodium vulgare'' \\\\\q\\\'s> 

 our common Eastern form. But this is from the botanist's stand- 

 point. The popular vote will be that it is much handsomer, by 

 its more slender lobes and generally graceful fronds. 



If we, as it seems we must, combine P. intcrmedmm with 

 P. Californiciini, it gives a wide geographical range to it on the 

 Pacific Coast from the Columbia River southwards. 



Explanation of the Plate. — i. An average sized plant. 2. An enlarged portion of a 

 division of the frond showing the veinlets and the soil thereon.
