“late, with ‘simple, double, or sometimes incised serratures, gener- 
ally elongated ; spikes thin, more properly filiform than in any of 
our species; calyx and corolla intermediate in shape, size, and 
color, between both parents. It resembles some varieties of the 
true V. paniculata, but the dark purple flowers, and the thick 
eylindric fruiting spikes, at once distinguish it.

Besides these four hybrids, I have found here the correspond-

nate by the same names, reversing the order, viz. 
‘hewe stricto-paniculata: greener, narrower, more petioled

of V. bracteosa with any but V. urticefolia, or of V. Aubletia, 
the only remaining species in this region, I have not yet found. 
The only other hybrid found by me in this country, is Rumer 
 obtusifolic-crispus. Whether these introduced plants hybridize 
in their native country is unknown to me.
