‘Mikania scandens L.A floret of this plant was found which 
had two of its filaments united. All the anthers were slightly 
united and were not essentially different in shape or size from 
other specimens examined. The filament in this species is made 
up of two distinct parts. There is a joint in the filament about 
.25 mm. below the base of the anther. Above this joint the tis- 
sue is made up of cubical cells. Their walls are comparatively 
thick and the tissue which they form is transparent. In the rest 
of the filament the cells are elongated, and the tissue they form 
is not transparent. The union of the filaments, in the case under 
consideration, begins in the transparent tissue, but is complete 
only in the portion below the joint. 
Hybrid, or not? In the March (1891) number of the BUL- 
LETIN, I called attention to the sterility of the achenia of So/idago 
serotina. Ait., var. gigantea, Gray, and mentioned that “this, 
taken with the place of growth and the intermediate character, 
would be evidence enough, at least, to suggest” that the plant is 
a hybrid. This judgment was based upon the principles govern- 
ing the determination of a wild hybrid, as set forth in Bentham’s 
“Handbook of the British Flora,” P. L. I wish to add that a 
careful examination of the plants of this kind in the stations of 
our Flora has failed to show one filled seed. W. W. ROWLEE. 
New Localities for Rare Plants. Hibiscus grandiflorus, Mx. 
—This well-marked species grows abundantly in an open swamp 
near White Hall, Greene County, Ill. This station is 70 miles 
north of St. Louis, and I believe the farthest north it has been 
recorded. 
Though closely allied to the showier H. Moscheutos, it is 
readily distinguishable by the velvety pubescenee clothing the 
entire plant, cordate leaves and hirsute pods. 
Veratrum Woodii, Robbins. At numerous times in the past 
few years, in the months of July and August, I have seen speci- 
mens of Veratrum growing on a brushy hillside near Uppet 
Alton, Madison County, Ill. I only caught fleeting glimpses of 
it from a passing train, but so conspicuous a plant is Vera/rum 
that it was easily recognizable as a member of the genus.
