Description: Crataegus tomentosa L.
"Leaves large (3' - 5' long), broadly ovate or oval, finely serrate, and slightly lobed above
the middle, abruptly narrowed into a short margined petiole,
pubescent, especially beneath, the veins straight and impressed;
corymbs large, tomentose; styles 1-3; fruit pear shaped, orange-red.
- Chiefly northern.
" Leaves broadly ovate, membranaceous, slightly toothed or entire,
pubescent beneath, slender-petioled, 3'-6', (5-13 cm) long;
flowers 0,5', (1.5 cm) wide;
fruit globose, red, 3" (5-7 mm) wide; styles mostly 2.
- River banks near Rome, Georgia. Aprill. -A small tree." -Alvan W. Chapman, 1897.
Description 2.: Crataegus tomentosa chapmani Beadle
"- So far I have not seen the typical C. tomentosa in the south, and I agree with Dr. Chapman in recognizing the form with very small fruit as a well marked variety. Near Biltmore, N.C., C. tomentosa Chapmani forms a small tree 4-6 m high, growing usually in rich soil and attaining a trunk diameter of 1 dm or less. The branches are gray, and armed with slender spines; leaves 5-12 cm long (occasionally larger), broadly ovate, prominently veined, sharply serrate and incisely lobed, and form sparingly to densely pubescent beneath: corymbs many-flowered, leafy, bearing glandular, caduceus bracts, and covered when young with fine, pale tomentum, which finally disappears: flowers small, 1-5 cm wide, ill-scented: calyx pubescent, the divisions lanceolate, serrate, acute: fruit sub-globose, 5-7 mm in diameter at maturity, bright red, long persistent.
Originally discovered on the banks of Silver creek, Floyd County, Georgia, by Dr. Chapman, whose name I have used in the new trinomial. The distribution is probably confined to the region of the southern Allegheny mountains." -C.D. Beadle, 1898.
