then abandoned by him for the preferred Osmorhiza, was for years 

 applied to the western Sequoias, and it is now in popular usage and 

 maintained by at least one professed follower of the law of priority 

 for a California!) palm. The name was not used for the umbellifer- 

 ous genus by any author besides its originator (and not even by 

 him !) within fifty years of its original publication, but in the mean- 

 time the name Osmorhiza was taken up not only by Rafinesque but 

 by other authors. The retention then of the name Osmorhiza for 

 the genus is in accordance with the definition of the Berlin rule, 

 which is now being recognized by conservative botanists as the most 

 rational law by which to gain uniformity in the selection of generic 

 names. The plant of the Rocky Mountains which has now been 

 discovered in southern Labrador should be known then as Osmorhiza 

 obtusa ( Washingtonia obtusa, Coulter & Rose), and it should be 

 watched for with some confidence in northern New England and 

 adjacent Canada. 



An Extension of Range for the Typical Lycopodium com- 

 planatu.m. — It was pointed out several months ago 1 that the plant 

 which has long passed as Lycofoiliiim complaiiatum in America is really 

 not that species as it is understood by European botanists, and the 

 European and American forms were forthwith described and the 

 ranges of both, in this country, appended. The true L. complanatum, 

 L. was cited as occurring as far south as Island Falls, Aroostook 

 Co., Maine. In the writer's herbarium, however, there are five 

 specimens collected on Pleasant Pond Mountain, Carratunk Planta- 

 tion, Somerset Co., — more than ioo miles southwest of Island Falls. 

 The Carratunk specimens show five good strobiles and as many 

 more old ones. The peduncles range from 2.5 to 4 cm. long and 

 the strobiles from 1.5 to 2 cm.; these are, in all cases, solitary. The 

 undivided terminal branchlets are slightly more than 2 mm. wide 

 but are not so long as in the specimens mentioned by Mr. Fernald 

 (1. c.) who, by the way, recently called the writer's attention to the 

 fact that the Pleasant Pond Mountain specimens represented an 

 extension of range. — J. Franklin Collins, Providence, R. I.
