of forms is not of so mucli interest to us, for \vc have several 

 smaller areas in western Vermont where there are more tlian 

 twenty forms ; we are more interested in the large tract practically

 the rest of the Point are pastured and most of this region is a 

 great thorn orchard and in many places a dense thorn thicket. 



One is surprised to find the dominant species the southern 

 Crataegus Criis-galli L., known in New England only at a few 

 stations in Connecticut and along Lake Champlain in Vermont. 



The northern Crataegus coccinca rotimdifolia Sarg. is also 

 abundant. 



As yet none of the group Teiniifoliae, the most common in 

 New England, has been found there. All of the forms in the 

 following list the writer has seen growing there excepting those 

 accredited to Professors Brainerd, Peck, and Sargent. 



Crataegus Cliauiplainensis Sarg.; C. eoceiiiea L., C. H. Peck ; 

 C. coccinca rotiDidifolia Sarg.; C Criis-galli L.; C. cxclnsa Sarg., 

 C H. Peck ; C. Jiahellata, Spach ; C Uolviesiana Ashe, Brainerd 

 and Sargent ; C. lobulata, Sarg.; C viacracantJia Koehne (also 

 a hairy form) ; C. praecoqna Sarg.; C Pringlei Sarg.; C priniiosa

Crataegus Porteri Britton. — Abundant flowering specimens 

 and ripe fruits of this species (described in Bulletin of the New 

 York Botanical Garden, i : 448) recently received from Mr. 

 Wm. M. Canby who has visited the region about Tannersville, 

 Pa,, where the type specimen was collected by me in 1896, en- 

 able me to supply the following supplementary description of the 

 plant : 



A tree 6.5 m. high or less, with long flexuous straggling 

 branches and a short trunk 1.5-2 dm. thick, with light-colored 

 and smooth bark. Leaves thickish, very smooth, rounded or
