ELEVENTH ANNUAL REPORT. 29 
The second is a Curatella from Guatemala which is remark- 
able for the very large deposit of silica in the leaves so that it is 
used as sandpaper by the natives. 
The third is an Amphitecna, a genus which has never before 
been studied in the field and whose fruit has never been described. 
The fruit is interesting as it is strikingly similar to a cacao pod, 
hanging down from the main trunk like cacao.

W. A, KELLERMAN, 
( Abstract. ) 
Distribution in Ohio noted of Lactuca scariola, Lactuca 
virosa and Lactuca saligna. Attention was called to the judg- 
ment on those forms by Dr. B. L. Robinson, who regards the 
one called by Dr. N. L. Britton ‘“Lactuca -virosa,’’ as a variety 
(integrata) of Lactuca scariola. Careful search for intermed- 
late characters, especially in the shape of the leaves, among many 
thousands of plants growing in the vicinity of Columbus, or 
collected elsewhere in Ohio, was not rewarded with success.
