From the above tabulation it may be seen that of the plants 
selected at random for examination 51 per cent, of the stems have 
three flowers and 49 per cent, have four or more; 10 per cent, have 
simple involucral leaves only, 44 per cent, have both simple and 
compound, and 46 per cent, have only compound involucrate leaves. 
Of the total number, 88 per cent, have one or all of the involucrate 
leaves petiolate, and 12 per cent, have only sessile ones. Observa- 
tions of others on this interesting little plant are solicited — especially 
should the Ohio botanists, amateurs and pupils furnish such notes 
for publication in the Ohio Naturalist. 
Explanation of Plate 9. — Syndesmon thalictroides ; the leaves, etc., were used as nega- 
tives and the photographs were reduced by the engraver to less than one-half the natural size. 
Figs. 1, 2 and 3 show leaves from the same plant ; figs. 4, 5 and 6 are from one and the same 
plant; figs. 7, 8, 9 and 10 are parts of the same plant; figs. 11, 12 and 13, also 14, 15 and 16 are 
each of one plant respectively ; figs. 17 to 23 inclusive illustrate leaf variation, specimens taken 
from different plants, except figs. 22 and 23 which are from one and the same plant.
