A very distinct species. Southwestern Georgia, and north- 
western Florida. HereI refer Nos. 2568 and 2377 G. V. 
Nash, 1895. 
Crataegus Holmesiana n. sp. A small tree 3--5 metres in 
height, with a rounded or flattened crown and long horizon- 
tal or spreading branches armed with numerous 3--4 cm, long 
straight or slightly curved thorns; or generally a large shrub. 
Leaves ovate, the blades 4--9 cm. long, 3--6 cm. wide, obtuse or 
acute at the apex, acute, obtuse or somewhat rounded at the 
base, coarsely and acuminately serrate all around, the teeth 
oland-tipped with 5--9 pairs of shallow lobes or doubly serrate, 
5--7 pairs of prominent veins, glabrous on both sides or when 
young sparingly pubescent beneath: petioles terete, slender, 
1.5--3 cm. long, generally purplish, and with a few stalked 
glands on it near the base of the leaf. Flowers in glabrous, 
nearly simple few-flowered corymbs, white, 1.5--1.7 cm. wide : 
petals nearly orbicular contracted at base into a short claw: 
calyx glabrous, the divisions glabrous, nearly entire; bracts 
and bractlets few, linear, glandular, not conspicuous. Fruit 
8--11 mm. thick, red, glabrous, falling early, 3--5 seeded. 
This species inits habit resembles C. mod/zs. It is separated 
from the nearly related species of the coccinea group by hav- 
_ ing much larger leaves with very acute serratures. Central 
New York. 
Crataegus atrorubens n. sp. A small tree or shrub. Branch- 
es gray: twigs bright red-brown, rather slender, marked with 
few pale lenticels: thorns few. Leaves oval, broadly ovate, 
or even obovate, the blades 3--7 cm. long, 2--5 cm. wide, ob- 
tusely and rather coarsely serrate, sometimes with 3--5, shal- 
low lobes towards the obtuse apex, or merely doubly serrate, 
4--6 pairs of prominent veins, entire at the rounded or subcor- 
date base, dark green above, slightly paler beneath, mem- 
branaceous, when young sprinkled with short appressed hairs 
on the upper surface, especially on the veins, and pubescent 
beneath in the axils of the veins, at length glabrate: petioles 
1.5--3 cm. long, very slender, finely pubescent, especially on 
the grooved upper surface. Inflorescence a 6--14-flowerce !
