Some Monstros!ITIEs IN PLANTS. 
By F. M. ANDREWS. 
In the proceedings of the Indiana Academy of Science for 1905, pages 
187 and 188, I have mentioned some interesting variations which I noticed 
in Trillium. Since that time I have been favored by the announcement 
of some additional monstrosities shown in Trillium by Prof. John M. Hol- 
zinger! of Winona, Minnesota, in a paper which he has been good enough 
eo send me. 
It occasionally happens that interesting monstrosities or variations. 
occur in other plants. Such variations, although very common, are never- 
theless often of great importance. 
One of the most common folear variations occurs in clover, and these 
I have found more or less abundantly, especially in Trifolium pratense. 
De Vries? states that he rarely observed clover individuals with more than 
one quaternate leaf. I have observed from time to time some specimens of 
elover which had one leaf-of four leaflets, and in one instance found two 
specimens of clover, each of which had in addition to ten regular leaves of 
three leaflets, seven (7) other leaves, each one of which had four (4) 
leaflets. One of these quaternate leaves was beginning to form a leaf hay- 
ing five (5) leaflets by the splitting process. Again another plant of 
clover near this one having seven quaternate leaves, had in addition to 
the ternate leaves, one with five leaflets. Another specimen of clover had 
ten leaves of five leaflets each, in addition to several ternate ones. One 
of these leaves with five leaflets shows the origin of the supernumerary 
leaflets by the splitting process, as De Vries describes on page 342 of his 
“Species and Varieties. Their Origin by Mutation,” 1905. 
Another specimen of clover had in addition to the usual ternate ones, 
one leaf having six leaflets, and another plant of clover, one leaf having 
seven leaflets. These plants all grew close together in a yard and were 
the only ones thereabouts which showed, in the many other specimens of 
clover present, any of the above mentioned deviations.
