Both oi these new species are of great interest since they are the 



first recorded indigenous forms from the eastern United States 



and show that the genus was present in this area throughout the 



Tertiary. They also throw an interesting Hght on the conditions 



of sedimentation at the time of their existence.

SHORTER NOTES 



Whorled Leaves in Gentiana. — In his notes on the flora of 

 Copake Falls, N. Y., Sereno Stetson describes and gives an illus- 

 tration of an unusual leaf arrangement in Gentiana quinguefolia 

 L., where whorls of three are shown instead of the normal 

 opposite phyllotaxis in Gentiana. Information is requested 

 from those knowing a similar case. There is one in my "herbarium 

 of G. Andrewsii Griseb., which I collected by Chautauqua Lake, at 

 Mayville, N. Y., September, 1907. One stem among those taken 

 has four whorls of three leaves, those of the uppermost nodes 

 below the leaves subtending the cluster of flowers at the top. 

 The stem was cut ofl^ near the root, and was about 4 dm. high, 

 2 dm. being occupied by the verticillate leaves. The four lower 

 nodes represented on the stem have the leaves opposite, so that 

 the entire stem does not share in the abnormality. One leaf 

 in the upper whorl has a flower in its axil. The only mention I 

 have seen of a similar case, except that of Mr. Stetson, is by Dr. 

 O. Penzig in his Pflanzen-Teratologie (2: 155. 1894). Under 

 Gentiana asdepiadea L., a plant of southern Europe, he says: 

 "Whorls of leaves with three members in place of the pair, not 



rare."
