A NEW Station for Asplenium pinnatifidum. — Afiplenium 

 'pinnatifidum Nutt. is a species hardly known to New England col- 

 lectors. In the summer of 1902 a plant of it was found at Sharon, 

 Connecticut, by Mr. E. I. Huntington and a note stating the fact was 

 published in the Fern Bulletin, xi. 14 (Jan. 1903). This was the first 

 and has remained the only reported station for the plant in New Eng- 

 land. The honor of discovering a second station in Connecticut for 

 this interesting little fern belongs to Mr. H. C. Bigelow of New 

 Britain, Connecticut. Mr. Bigelow is an enthusiastic student of our 

 fern.s and in the summer of 190(3 found three plants of ,1. pinnafifidum 

 growing on an outcropping ledge of shale in Southington, Connecti- 

 cut. It was growing with Aspknium plaiyneuron Cakes, and Camp- 

 tosorus rhizophijUus Link, and there was at first some question 

 whether it might not be a form of the much discussed A. ebenoides R. 

 R. Scott, but a careful comparison with other material showed there 

 could be no doubt as to its identity with A. pinnatifidum Nutt. The 

 station at Sharon is about twelve miles farther north than Southington, 

 but the latter station is more than thirty miles farther east, bringing 

 the range of this fern well into the central part of Connecticut. One 

 of the plants found at Southington has been placed at the (jray Her- 

 barium.— C. H. BissELL, Southington, Connecticut. , 



Principles of Botany.^ — It was to be expected that Mr. Bergen 

 and his associate Dr. Davis, authors of the new " Principles of Botany" 

 recently published by Ginn & Co., would make an excellent text-book. 

 Both have had long experience as teachers, both are eager students 

 and investigators, each in his chosen field of the science, and both are 

 able to command forcible and lucid English. Thus the book is emi- 

 nently readable. Mr. Bergen, besides, from previous success in the 

 same line, knows how to put a text-book together. In this volume 

 he has divided the field with his asst)ciate, taking the chapters on the 

 structure and physiology of seed-])lants, as well as those on ecology 

 and economic botany, and leaving to Dr. Davis the treatment of 

 morphology, evolution, and cla.ssification of plants. 



Mr. Bergen's chapters embody a fresh treatment of topics which he 

 has already shown ability to present in his earlier text-books. The 

 arrangement is even better than before. Especially commendable 

 (though not new) is the combination of demonstrations of structure
