326 THE BOTANISTS OF PHILADELPHIA. 



herbarium. Mr. Martindale paid considerable attention to 

 the peculiar and miscellaneous plants of the ballast grounds, 

 and this class, difficult of study to the ordinary student, 

 because not contained in our local manuals, is likewise well 

 represented. 



" In addition to making extensive collections himself, 

 and exchanging with numerous botanists, both at home and 

 abroad, he acquired, by purchase, the best collections offered. 

 No collector submitted a list of desirable plants but that he 

 was made happy by an order from Mr. Martindale, and he 

 was a liberal contributor to every botanical expedition. 

 Among the many noted American collectors, whose col- 

 lections are here represented, may be mentioned : Parry, 

 Garber, Lemmon, Rothrock, Rusby, Curtiss, Howell, 

 Reynolds, Palmer, and those magnificent collections made 

 in the southwestern states and territories and in Mexico, by 

 C. G. Pringle. 



" In 1881 he purchased the herbarium of Dr. Ferdinand 

 Rugel, of Tennessee, which was replete in the representation 

 of the flora of the southern states, thus receiving a large 

 addition to his already extensive collections from this 

 region. These specimens were remounted and distributed 

 through his herbarium. A great part of the herbarium 

 of his friend and co-laborer, Charles F. Parker, who had 

 made a special study of the flora of New Jersey, is preserved 

 in this collection. Likewise the collections of C. F. Austin. 



" No expense was spared to make his herbarium com- 

 plete and perfect in every respect, and the outlay was large. 

 It is estimated that in the collection and arrangement of 

 this magnificent herbarium, Mr. Martindale had spent 

 at least §15,000.
