SHORTER NOTES 



A Teratological Note on Timothy. — The usual farm crops 

 afford many instances of double (and sometimes triple) fruits. 

 Such specimens of red clover and field corn are rather common. 

 I have never noticed such abnormalities in timothy, however, 

 until this year, when a partially double head of timothy was 

 found in our lane. The whole head is 7.6 cm. long, being single 

 for 4 cm. of its length and having the upper part divided into two 

 stalks of 3.6 cm. each. The upper divisions are almost equal in 

 diameter to the basal part, and are fully fruited, except occasion- 

 ally on the inner sides. The divisions diverge at an angle of 35 

 degrees. H. R. Romine. 



Abnormalties in the Radish, Clover, and Ash. — Several 

 seedlings of the radish grown by our students this year in their 

 seed germination studies had one cotyledon some distance below 

 the other ; in one instance the cotyledons were 3 cm. apart. A 

 specimen of white clover, Trifolium hybridum, was found along 

 the roadside this June with seven large flowerets 2.3 cm. below 

 the head itself. The flowerets of the head were perhaps not so 

 numerous as usual. From an American ash tree near our school 

 buildings I picked several leaves which to me seemed very un- 

 usual. There were two sets of leaflets instead of one set at the 

 nodes along the rachis ; some had three pairs of such doubles 

 instead of three pairs of leaflets. Emmeline Moore.
