open country round about. Repeated searches in the Stude- 
baker woods were rewarded by the discovery of a number of 
individuals that were sterile. I think I gathered the few I found. 
To my dismay I now find that they are not the males of either 
A. mesochora or occidentalis, not even right males at all. Their 
elongated involucres and undilated pappus-bristles declare them 
to be of that third phase, the neutral or the false-hermaphor- 
dite one, of which mention is made above. If the real male plant 
shall come to light, either from the woods named, or, along with 
the female, from elsewhere, then may we hope to ascertain what 
the species is. 
It is evident that not all the large-leaved plants of the prairie 
region can be distributed between the two species last named; 
but with the scanty materials at hand representing too imperfectly 
one or two species, perhaps yet to be made out, nothing more 
can be done. 
A. CALOPHYLLA, Greene, Pitt. uli 347. M7. Septe aeogare 
Readily known at whatever stage of growth by the great dimensions 
of its foliage, the largest leaves more than two inches wide and 
not much longer, of thin texture, and permanently flocculent 
above. Known only from the limestone districts of southern 
Illinois and adjacent Missouri; but it should be looked for in 
similar parts of extreme southern Indiana, which still remains 
a region botanically unexplored. 
IV.—NEW PLANTS FROM NORTH DAKOTA. 
By J. LUNELL. 
During my botanical excursions in this state I have for many 
years paid a special attention to the multi-variable behaviour of 
the group of plants, known as Lacimiaria scariosa, and made 
efforts to penetrate the secrets governing its remarkable changes. 
I have also had a splendid occasion to widen the scope of my 
observations by studying the fine material of Mr. C. C. Deam, 
secretary of the Indiana State Board of Forestry, who kindly 
placed it at my disposal, thereby enabling me to confirm my
