5. Rowlee, W. W. " Notes on Antillean Pines with Description of 

 a New Species from the Isle of Pines." Bulletin of the Torrey 

 Botanical Club, XXX, 1903, pp. 106-108. 



Pinus recurvata Rowlee and Pinus cubensis var, anomala Rowlee 

 are here described as new. 



6. Urban, Ignatius. In his "Flora Portoricensis," Symbolcs An- 

 tillance seu Fundamenta FlorcE Indies Occidentalis, IV, 1903-191IJ 

 Urban gives the general distribution of the various species cataloged 

 therein for Porto Rico, and, among the various localities listed, the 

 Isle of Pines frequently occurs, evidently based on the A. H. Curtiss 

 Collection. Volumes V, VI, and VII of the Symbolce Antillance also 

 contain a number of references to plants from the Isle of Pines, 

 mainly from the Curtiss Collection. Descriptions of new, and reports 

 as to the distribution of previously described, species are given. 



7. Britton, N. L. In the Bulletin of the Torrey Botanical Club there 

 have appeared at irregular intervals for a number of years past a series 

 of articles, entitled "Studies of West Indian Plants." In these 

 articles Dr. Britton has dealt to a limited extent with specimens col- 

 lected in the Isle of Pines, giving descriptions of a few new species. 



8. North Aynerican Flora. In certain recent numbers of the 

 North American Flora there are to be found references to the Isle of 

 Pines, either in the paragraphs on general distribution of the species, 

 or, in a few cases, new species are proposed based on specimens from 

 the Isle of Pines. 



For new species see Lotoxalis pinetorum Small, North American 

 Flora, XXV, 1907, p. 49, Kalmiella aggregata Small, op. cit., XXIX, 

 1914, pp. 54-55, Xolisma vaccinioides Small, op. cit., XXIX, 1914, 

 p. 68. 



Q. Harshberger, John W. Phytogeographic Survey of North America, 

 in Engler & Drude, Die Vegetation der Erde, XIII, 1917. 



Under the heading "Cuban District," in the treatment of the 

 Antillean Region, Harshberger gives lists of species under various 

 ecological groups, these lists being mainly derived from Rowlee's 

 articles. (See above.) 



10. Hitchcock, A. S. "Grasses of Cuba," Contributions from the 

 U. S. National Herbarium, XII, 1909, pp. 183-25S. The Isle of Pines 

 is included in Cuba by Hitchcock, and various references are made 

 to the Taylor, Palmer & Riley, and Curtiss Collections from the 

 Isle of Pines. Curtiss' No. 420, Isle of Pines, is proposed as a new 

 species, Eragrostis cubensis Hitchcock.
