A flower stalk of salsify was marked for its upper six inches and 

 it increased in length a half inch, all of which was confined to the up- 

 per third of the marked space. The same was true of others of the 

 same species. 



The flower stalks of Ranunculus bulbosus showed the same slight 

 increase as salsify. 



A flower stalk of Narrow-leaved Plantain {Plantago lanceolatd) 

 elongated one inch in the upper five inches of the marked stem and 

 the largest amount was in the upper-most half-inch space and the elon- 

 gation decreased in the succeeding spaces until it was nothing at the 

 third inch from the spike.

A NEW FOSSIL EUCALYPTUS FROM KANSAS. 



By Lester F. Ward. 



IN a small collection of fossil plants from the Middle Cretaceous 

 (Dakota Group), of Clark county, Kansas, which was made by Mr. 

 C. N. Gould and myself on Oct. 3, 1897, there occur several leaves 



that belong to the genus E^icalyptus One of these is entirely dif- 

 ferent from any of the rest and presents a nervation which at once marks 

 it as a species new to science. Although it is not generally advisable to 

 name species of fossil plants from single specimens, especially from 

 one incomplete leaf, nevertheless, so exceedingly clear is the nerva- 

 tion in the present case, that there is no room to doubt either its 

 generic affinity or its specific distinctness from all other species of 

 the genus. So much of the material that has been called Eucalyptus, 

 which has been reported from various deposits throughout the world, 

 is of a doubtful character that it is desirable that any case involving- 

 no uncertainty be brought to the attention of botanists and geologists. 

 I regard this as such a case and ventured to describe it in the Decem- 

 ber number of the Bulletin of the Torrey Botanical Club as a new 

 species. I named it Eucalyptus Gouldii., in honor of Mr. Gould, who, 

 as stated above, assisted in its collection. 



Of all living species of Eucalyptus this approaches most closely 

 in its nervation to that of Eucalyptus largijlorens^ first described by
