species of Prunus than in the ease of some other woody plants, the 

 pines and oaks for instance. The interested reader may find it worth 

 while to study the statements about the habitats of Prunus in Sargent's 

 Silva, Wight's Native American species of Primus (U. S. Dept. Agr. 

 Bull. 179. 1915), and some of the more elaborate local Moras, such as 

 the recent flora of Connecticut by Graves and others, Stone's flora of 

 southern New Jersey (referred to by Mr. Long, and reviewed by the 

 writer in Torreya 12: 216-225. 1912), Kearney's Botanical Survey of 

 the Dismal Swamp region, and Mohr's Plant Life of Alabama. 



Many other genera of plants of course are just as sensitive to fire 

 as Prunus is, and any one who wishes to look further into the effects of 

 this neglected environmental factor can find references and cross- 

 references in the following places: — Bull. Torrey Bot. Club 38: 522.

Reprint of a rare Book on American Plants. — Mr. S. N. 

 Rhoads of Philadelphia has made accessible to botanists, through 

 reprinting, "the earliest published book, written by an American 

 Botanist and devoted exclusively to American Botany, Horticulture 

 and Floriculture." l This work is divided into two parts, 1. Cata- 

 logue d'Arbes, Arbustes, et plantes herbacees d'Amerique. 2. Liste 

 des Arbres, Arbrisseaux & Plantes qu'on ne peut se procurer que par 

 des voyages dispendieux dans le continent de l'Amerique, & que 

 M. Yong n'a point encore eleves en assez grand noinbre pour les 

 envoyer en Europe. Many of the names are binomials and some of 

 them are characterized as'" nova species," but the descriptions are 

 so meager and vague that they have little defining power, as for in- 

 stance " Angelica pastinaca, nova species. Pale a 5 pieds de haut & 

 croit dans un sol marecageux," and, therefore, they should not be 

 taken up to displace names with good descriptions made later. This 

 old book has been neglected or overlooked for many years. It does 

 not appear in the botanical bibliographies and the new names are 

 not cited in the Index Kewensis. William Young Jr., the author, 

 was a nurseryman and a gardener, a near neighbor of John Bartram
