A Great Day. 87 



and clamber over the top of the brush or break our 

 way through. We felt like veritable explorers mak- 

 ing our way through an entirely new country. 



As we worked our way down the ravine we suddenly 

 came upon a bank on which grew a great quantity of 

 Adiantum Jordani C. Muel., interspersed with Poly- 

 podium Calif ornicum Kaulf. A little further down we 

 found some large clumps of Woodwardia radicans (L) 

 Sm., some of last year's fronds, six feet or more in 

 height, still remaining and showing its characteristic 

 fruiting, but the new fronds not fully uncoiled. 



We were now quite jubilant and ready to vote our 

 trip a great success, but it seemed to be only a beginn- 

 ing, for we soon discovered Pellaea andromedaefolia 

 (Kaulf.) Fee., P. ornithopus Hook, and another that 

 may be only an immature form of andromedaefolia, 

 though it was in full fruit. But I find that P. andro- 

 medaejolia is quite diverse in its growth, being bi- tri- 

 or qu adripinnate, and the ultimate pinnules on some 

 plants being less than half the size of others. I think 

 the tendency is for them to become more times pinnate 

 as the plants grow older. I hope to clear up this point 

 by watching individual plants in my wild garden. 



Farther down the canyon we found a quite large area 



densely covered with tall, waving fronds of Pteris aqui- 



ina L. with some more clumps of Woodwardia radicans, 



and a little farther the bracken was interspersed with 



Equisetum robustum A. Br. 



It was now getting late and we had not yet reached 

 the mouth of our canyon so we began to hurry along, 

 but we just couldn't get away without finding one more 

 fern, for on a little bank we found two or three plants of 

 Cheilanthes Calif or nica (Nutt) Mett. We were now 

 rich indeed. Our Southern California fern flora is not 

 very large at best, and here in one afternoon in one little
