or bark of Pinus Elliotti but its leaves and cones have the same 

 characters and it is probably the same species. Some authors 

 state that Pinus Elliotti is replacing P. palustris wherever the 

 latter is cut away, but this does not seem to be the case to any 

 appreciable extent in Georgia, where P. palustris reproduces 

 itself freely. 



Pinus heterophylla was originally described very briefly by 

 Elliott as Pimts Tacda var. heterophylla. It is improbable that 

 Elliott would have considered the slash pine, had he really 

 known it, as a variety of Pinus Taeda. There is, however, a 

 pine growing along the coast of Georgia, in situations like that 

 described by Elliott for his variety heterophylla^ which has much 

 the appearance of Pinus Taeda, though probably entitled to 

 specific distinction. 



A pine which is sometimes chipped for turpentine, but fails to 

 yield any, is Pinus serotina Michx., a comparatively little-known 

 species. This ranges from North Carolina to Florida, occurring 

 in sandy swamps. In Georgia, it is widely but sparsely distrib- 

 uted over the coastal plain, extending inland to within a few 

 miles of the fall-line. Its cones are quite characteristic and re- 

 main on the tree for years, whence its name. It can be distin- 

 guished at a glance by its habit of sending out short branches all 

 along the trunk, probably from adventitious buds.

The second paper was by Dr. W. A. Murrill and was entitled 

 " Remarks on some Generic Types among the Polyporaceae." 

 Dr. Murrill gave a resume of the treatment of the genus Polyporus 

 and the family Polyporaceae by Micheli, Dillenius, Linnaeus, 

 Adanson, Haller, Scopoli, Paulet, Palisot de Beauvois, Pollini, 

 Fries, Gillet, Karsten, and others, discussing the historical types 

 of Polyporus, Agaricus, Favolus, Hexagona, Cyclomyces, Lcnzites, 

 Gloeophyllum, Pomes, Ganoderma, Elfvingia, Cryptoporus, and 

 Pyropolyporus. Some of the more striking characters of the 

 genera were illustrated in an artificial key. The results of Dr. 

 Murrill's studies among the Polyporaceae have recently been or 

 soon will be published in the Bulletin of the Torrey Botanical
