Juncus macrophyllus Goville, nom. nov. Juncus canaliculatus 

 Eugelm., Bot. Gaz. vii. 6 (1882), not Liebmann (1850). 



Dr. Engelmann considered this species, when he described it, 

 most nearly related to Juncus marginatus Rostk., but its closest 

 ally is undoubtedly J. longistylis Torr. The red color of the 

 anthers, which was given as a specific character in the first 

 description, and which was the basis of the affinity originally 

 assigned it with marginatus, is not constant, even in the type 

 specimen, a portion of which, through the kindness of Mr. S. B. 

 Parish, I examined several years ago. In open flowers of speci- 

 mens collected by Dr. H. E. Hasse near Los Angeles, California, 

 the anthers are of the pale yellow color usual in the genus, while 

 in a mature fruiting specimen collected by him they vary from a 

 reddish to a blackish brown. Under suspicion of being diseased, 

 some of these red anthers were examined at my request, in 1893, 

 by Mr. D. G. Fairchild, who reported that a Gladosporium was 

 present in abundance and that the reddening of the tissues was 

 undoubtedly caused by this saprophytic fungus. 



Juncus macrophyllus may be contrasted with Juncus longistylis 

 by the following characters: rootstock 1.5 to 3 mm. in diameter, 

 stouter and shorter than in J. longistylis; stem stouter than in
