Crataegus illustris n. sp. 



A small tree or large shrub 3-6 m tall with a short trunk 

 sometimes i-i-5 dm in diameter clothed with scaly, rough bark 

 of a dark gray or brownish color, the ascending or spreading 

 branches forming a symmetrical open crown : leaves broadly 

 ovate or oval, 3~5 cm long exclusive of the petioles, 2-5-5 cm wide, 

 acute or obtusely pointed at the apex, rounded at the base, the 

 borders serrate and mostly with rounded, lobe-like incisions ; 

 they are glabrous, firm to subcoriaceous in texture, bright green, 

 fading in autumn with tones of yellow, orange and brown : peti- 

 oles 1-2. 5 cm long, margined: flowers i4-i8 mm wide, expanding 

 the latter part of April and when the leaves are two-thirds grown ; 

 they are produced in simple, 3-6-nowered corymbs which termi- 

 nate short leafy branchlets : pedicels glabrous, 7-1 3 mm long : hy- 

 panthium glabrous : sepals triangular-lanceolate, about 3 mm long, 

 serrate or nearly entire, reflexed after anthesis : stamens 15-20, 

 the anthers dark purple : fruit, which ripens in October, de- 

 pressed-globose, about i cm in diameter, the flesh firm : nutlets 

 3-5, 6-7 mm long, the lateral surfaces nearly plane : hypostyle about 

 half the length of the nutlet. 



Crataegus illustris is a remarkable species both on account of its ample, 

 very broad leaves and its peculiar, depressed fruit. 



The original specimens {H4.200 and /J4200 2 ), which are deposited in the 

 Biltmore Herbarium, are from a tree found growing on a gravelly hill near 

 Meridian, Mississippi. 



Crataegus assimilis n. sp. 



A small tree or large shrub 3-6 m tall sometimes with a trunk 



1- i.5 dm in diameter covered with dark gray or brownish scaly 

 bark, the ascending or spreading branches occasionally armed 

 with stout spines 1-2. 5 cm long: leaves ovate or oval, the blades 



2- 5 cm long, i.5-4 cm wide, acute at the apex, contracted or rounded 

 at the base, the borders serrate and with rounded, lobe-like in- 

 cisions ; they are glabrous, or at the time of unfolding bear a 

 few weak hairs along the midrib on the upper surface, firm in 

 texture, deep green, fading in autumn with tones of yellow, orange 

 and brown: petioles ymm_ 2 cm long, margined: flowers i5-i8 mm 

 wide, opening early in April and when the leaves are about two-
