ST. JOHN: SABLE ISLAND. 61 



GRAMINEAE. 



Panicum huachucae Asbe. Occasional in the drier spots. 

 J. Macoun (C. no. 22,708), labeled P. implicatum; H. St. John, nos. 

 1,129 and 1,130 (H). 



Fr. July and August. 



[PANICUM IMPLICATUM Scribn. J. Macoun 's collection was so 

 labeled by Hitchcock and Chase, but the size of the spikelets and the 

 character of the pubescence indicate that this plant should rather 

 be treated as P. huachucae.] 



ECHINOCHLOA CRUSGALLi (L.) Beauv. A garden weed at the Main 

 Life Saving Station. H. St. John, no. 1,131 (H). 

 Fr. September. 



ANTHOXANTHUM ODORATUM L. Established on the drier, more 

 stable parts of the island. J. Macoun (M. p. 218A) comments on 

 the abundance of this species on the old land and argues that it 

 appears native there, or at least is " a resident of such long standing 

 that it has made itself at home in all suitable places. " H . St. John, 

 no. 1,132 (H). 



Fr. August. 



PHLEUM PRATENSE L. Planted and well established near the 

 Life Saving Stations. Observed by J. Dwight, Jr. (D. p. 12); 

 collected by J. Macoun; H. St. John, no. 1,133 (H). 



Fl., Fr. August. 



AGROSTIS ALBA L., var. VULGARIS (With.) Thurb. Cultivated 

 near the stations, according to J. Dwight, Jr. (D. p. 12). 



A. alba L., var. maritima (Lam.) G. F. W. Mey. Abundant in 

 the dune hollows and at the margins of the fresh-water ponds. Col- 

 lected by J. Macoun; H. T. Gussow (E); H. St. John, nos. 1,134 and 

 1,135 (H). 



Fr. August. 



A. [A collection by J. Macoun (C. no. 73,060) obviously belongs 

 to the alba series, but I have been unable to place it to my 

 satisfaction. 



[A. HIEMALIS (Walt.) B. S. P. Both Macoun and Gussow list 

 this species, but the plants are probably to be interpreted as of the 

 var. geminata.]
