United States it becomes ipso jacto, in their estimation, native in 

 the state or county covered by the flora, even if it is there strictly 

 confined to weedy habitats. Mr. Deam did not go quite to that 

 extreme, but he gave many weeds the benefit of the doubt, and 

 classed them as natives. My acquaintance with Indiana vegetation 

 is chiefly confined to car-window notes in about one-fourth of the 

 counties, between 1911 and 1941, but from what I know of the same 

 species elsewhere, I would judge that his 302 introduced species 

 should be increased to about 500, and the natives correspondingly 

 reduced. 



Many valuable features of the book, such as keys and distribu- 

 tion maps for every species, the tabular summary, the descriptions 

 of natural regions, the bibliography of about 700 titles, and the list 

 of Indiana botanists (142 men and 29 women) have been discussed 

 by previous reviewers. It is worth noting here that the 41 botanists 

 who have died lived about 61 years on the average; the later ones 

 a little longer than the earlier ones. 



Typographical errors are very few, and mostly easily detected. 

 One minor fault of the book is the use of too many fictitious common 

 names, some of which are longer than the technical names, and not 

 likely ever to come into general use, and thus serve no useful

FIELD TRIPS OF THE CLUB 



Trip of August 2-3, 1941, to Southern New Jersey 



Mr. Hollis Koster of Green Bank, a competent student of pine 

 barrens natural history, showed us many interesting species in that 

 area. Some of the species bring to mind early botanists of the area. 

 Among these were Rynchospora knieskernii, Lobelia canhyi, Poly- 

 gala mittalii, and Panicuni commonsianum. The writer was inter- 

 ested in adding Jmicus caesariensis, Smilax walteri, and 5". lauri- 

 folia to the list of plants occurring at the ghost town, Martha. 

 Mistletoe (PJioradendron flavesceus) is a plant that many of us 

 had not previously seen on a field trip in New Jersey. In the Bass 

 River State Forest a tree designated as Quercus imhricaria brought
