H. Kalmianum has been found in Central Tennessee, and a 
new species named by Dr. Gattinger A. lobocarpum is also re- 
ported from W. Tennessee, which seems to be a center for this 
group, as eighteen species are found there.

Mr. Meehan concludes, after a study of Mahernia verticillata, 
Cav., and other plants, that “in many cases superimposed 
stamens are the development of theoretical axial buds at the 
base of the petals” being thus of a cauline rather than of a phyl- 
line nature. He remarks that this theory relieves us of the diffi- 
culty met in the supposed interjection of an extra whorl of leaves 
in the production of these structures, for which there is no war- 
rant in phyllotaxis.
