Buckleva, since it sometimes reaches the size of a 
small tree, is the largest known American parasite. It 
has many more fibrous roots than Darbya and the sub- 
terranean stem is not so extensive. The clasping disks 
by which attachments are made are larger and somewhat 
more cup-shaped than are those of Darbya. It is chiefly 
parasitic on the small roots of hemlock, beech, sugar 
maple, birch (sp. ind.) and red oak. It can be cultivated 
in the same manner as Darbya. 
The manner of propagation of Pyrea/aria is like that of 
Darbya but the underground stems are shorter and more 
abundantly supplied with small roots.

For many years a plant which was originally described 
by Pursh’ as Robinia hispida var. rosea has been con- 
fused with the Robinia hispida of Linneus by both 
American and Kuropean authors. This confusion origi- 
nated from the inadequacy of Pursh’s’ description; and 
has been continued by later writers who, having no spec- 
imens of Pursh’s plant for comparison, transferred its 
name to smooth or nearly smooth forms of PR. hispida 
which seemed in part to agree with the description of 
the variety rosea. Asa matter of fact the variability of
