only ; it differs from this species in its much smaller size and in its 

 strongly incurved leaves which are hairy on the lower surface near 

 the base and often toothed. Mature strobiles are a desideratum.

CLAVATUM GROUP 



It is a difficult problem to distinguish many of the species of 

 this group, a large proportion of which Baker reduces to the single 

 species L. clavatnm, whose distribution is curiously given as 

 " Arctic and alpine zones of both hemispheres, also mountains of 



Polynesia." In J

not able to separate on structural grounds from our common 

 northern species, f although it differs toto coelo in habit. In place 

 of our unobtrusive close-creeping plant, the Jamaican form is 

 rampant in great masses over the paths about the Cinchona plan- 

 tation, forming a weed, and sprawling over low shrubs in the 

 greatest profusion. Material from the whole world will be needed 

 to elucidate the relations of the species involved in this polymorphic 

 tangle. Besides abundant material from Jamaica we have imperfect 

 collections from Mexico, Guatemala, Colombia, Guiana, Brazil, 

 Ecuador and Bolivia, but insufficient for monographic purposes. 

 For these reasons we prefer to leave the Jamaican plants for the 

 present under

Europe). 



Range : Europe and North America from the Arctic zone as far 

 as Pennsylvania ; also (provisionally) Jamaica above 5000 ft., and 

 possibly Mexico and Guatemala. 



*L. Eichleri F6e, Crypt. Vase. Bres. //. 106. /. 4, cited by Baker as a synonym, 

 is apparently distinct if Fee's plate is to be relied on, and his plates are usually 

 extremely reliable. Mr. Baker further cites this species incorrectly as L. pendulum. 



| With a distribution scattered well over the Northeastern States extending as far 

 west as Washington State and Southward to Pennsylvania, this species is far from being 

 either "arctic or alpine" in America, although it does attain both these regions in this 

 country as in Europe.
