38 Rhodora [Fkbkuary 



ments. In/, oronensis, on the other hand, the capsule is oblong, trun- 

 cate-emarginate, at most mucronulate. the sides flat or at tips concave ; 

 the larger spindle-shaped seeds have distinct white caudate appen- 

 dages ; and the anthers equal the filaments. These characters place 

 the plant very near the northern /. Vaseyi, but from that it is clearly 

 distinct in its elongate subdichotomous inflorescence, long bracts, cap- 

 sule shorter than the perianth, and in the short caudate seeds, those 

 of/. Vaseyi having the tails more than half as long as the dark body. 



Juncus Torreyi, Coville. The only New England station known is 

 along a railway ditch at Chelsea, Massachusetts, found by Mr. W. P. 

 Rich > in 1901. The species is ordinarily of inland distribution, from 

 western New York and adjacent Pennsylvania westward, and it is 

 probable that the Chelsea plant is of recent introduction. 



Luzula campestris, DC, in its typical form, a loosely caespitose and 

 strongly stoloniferous plant with 2-6 large (6-7 mm. thick) casta- 

 neous spikes on wide-spreading or decurved peduncles, seems to be 

 confined to northern Kurope. Its common representative in Amer- 

 ica, as in parts of FAirope and Asia, is var. mu/tijlorn, Celakovsky, 

 Prod. Fl. Bohmen (1869) 85 (L. niii/fiflora. Lejeune) , densely caespi- 

 tose, with the 3 to 12 subglobose or oblong ferruginous or pale 

 brown (greenish in deep shade) spikes on mostly ascending peduncles. 

 N?iX. frigida, Buchenau, Oest. Hot. Zeitsch. xlviii. (1898) 284, with 

 very short peduncles and subglomerulate dark brown to nigrescent 

 spikes, occurs from Greenland to Newfoundland, and reaches our 

 district in northern and eastern Maine. 



Juncus bufonius and its Rkcrksentativks in America. 



During the summer of 1902 members of the New England Botanical 

 Club who botanized on the coast of eastern Maine and the Maritime 

 Provinces were much interested in the variations of Juncus bufovius, 

 and particularly in its behavior upon the salt marshes and below the 

 limit of high tide. Abundant material was secured and during the 

 following winter the writer undertook a study of the species. The 

 results of this study were the decision that in North America we have 

 not only irw^Juticns bufonius with certain well marked varieties and a 

 number of trivial forms, but that in the western districts, from the 

 Rocky Mountains to California, etc., much which has passed as/. 

 bufonius is the well-known Old World species, /. sphaerocarpus. in 

 order to verify his conclusions the writer sent materials and notes to 

 the distinguished specialist on the Juncaceac, Prof. Franz Buchenau 

 of Bremen, and after a detailed correspondence and a study of 

 much material, generously augmented by critical specimens from Prof^ 

 Buchenau, he presents the following treatment of /. bufonius and its- 

 allies as known to him in North America.
