nos. 62-67. 
A monotypic group restricted to northeastern North 
America. It has no strongly marked characters, but as 
it shows no close relation to any other species, it seems 
best to consider it as representing a separate subsection. 
- Its nearest affinity is with the Alpigenae, but it differs 
chiefly in the obsolete bractlets, wholly adnate to the 
ovaries and therefore indistinct, by the very caducous 
bracts, the absence of glands, the kind of pubescence and 
the small seeds. JZ. oblongifolia may be considered the 
American representative of the Alpigenae of the Old 
World, but it is less closely allied to that group than is L. 
conjugialis to the Old World Rhodanthae. Both species 
differ from their allies in the caducous bracts and the 
tendency of the bractlets to become obsolete.
