91. Crataegus berberifolia T. & G. Barberry-leaved 

 Haw, He Hog-apple. 



A low broad-topped tree with many stout thorns, 

 1-2 inches long. This tree reaches its northern limit 

 in North Carolina and is not rare on the hills around 

 Chapel Hill. Leaves ovate-spatulate, %-2^2 inches 

 long, V s -1 inch wide, thick, shiny and rough pubes- 

 cent above, softly and rather sparcely pubescent be- 

 neath, toothed above, the lower half or third even; 

 flowers in clusters of five to nine, the flower-stalk and 

 ovary very hairy ; fruit oblong, dull orange or red or 

 greenish-red, 5 / ie -% iuch thick, the surface slightly 

 short hairy under a lens at maturity. This Haw is 

 called the He Hog-apple around Chapel Hill on ac- 

 count of the usual lack of fruit, and this year (1916) 

 for the first time we have found a little fruit on 

 them.* Dates of flowering : May 20, 1901 ; May 7, 



* It has recently been shown that many of the supposed species 

 of Crataegus are probably. hybrids, with a large part of the pollen 

 aborted (Journal of Heredity 7:266. 1916).
