scirpea, are all referred by Bentham to Verbena, but they have 
all precisely the same habit as D. juncea, and I should 
not be surprised if they proved to be forms of that plant. 
Walpers (Repertorium iv. 16) includes D. juncea and some 
of the others in a section (Juncex) of Verbena, together with 
some other Verbenacex, which, as Miers observes, have no 
affinity with these. : 
In D. juncea the teeth of the calyx vary a good deal in 
development, being sometimes hardly perceptible; the 
stamens vary in number; of the specimens cited by 
Miers, the type, that collected by Gillies, has no fifth, 
which is present in Macrae’s and Bridge’s specimens. 
D. juncea is a native of the Chilian and Argentine Andes, 
at elevations of three thousand to five thousand feet, from 
the latitude of Mt. Aconcagua to that of Valdivia. There 
are three small trees of it in the Royal Gardens, Kew, in 
a bed close to No. 2 House, where they flower in June; 
they were raised from seed received about ten years ago, 
but there is no record of their source. 
Descr.—A bush or small tree, branching from the base ; 
branches erect, spreading, or recurved, branchlets opposite, 
ternate, or quaternate, internodes very long, green, terete,

_ Leaves in very distant pairs, rarely one inch long, opposite,
