scabrous on the upper surface at maturity, usually with some 

 pubescence along the midrib beneath, and when young are spar- 

 ingly pubescent on both surfaces, lustrous above, pale below, 

 eventually firm or subcoriaceous in texture, fading with tones of 

 yellow, orange and brown : petioles 2-io mm long, pubescent, at 

 least when young : flowers io-i4 mm wide, opening about the 

 ioth of April and when the leaves are almost fully grown ; they 

 are produced in small, congested, compound, 5-12-flowered co- 

 rymbs which terminate short, leafy branchlets : pedicels spar- 

 ingly pilose : hypanthium glabrous or with a few hairs at the 

 base: sepals 3-4. 5 mm long, entire or slightly serrate: stamens 

 16-20, the anthers light yellow or almost white : fruit, which 

 ripens and falls in September, subglobose, 8-g mm thick, at matu- 

 rity orange-yellow with red or ruddy cheeks : nutlets mostly 2-3, 

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

 two-thirds the length of the nutlet. 



Cratczgus edura grows in upland woods near Opelousas, Louisiana (type 

 locality) . 



The type material, consisting of flowers (I/4/jS) and fruit {H4138 2 ) from 

 the same tree, is preserved in the Biltmore Herbarium. 



Crataegus tersa n. sp. 



A tree 4-6™ tall with a trunk sometimes i.5-2 dm in diameter 

 clothed with dark gray or brownish scaly bark, the spreading 

 brauches forming a wide crown : leaves oblong- or obovate-cunei- 

 form, the blades 2-6 cm long, 1-4. 5 cm wide, rounded or obtuse, or 

 on leading shoots slightly pointed at the apex, wedge-shaped or 

 more abruptly contracted at the base, the borders serrate or 

 crenate-serrate above the middle ; they are lustrous and glabrous 

 or slightly scabrous on the upper surface at maturity, more or less 

 pubescent beneath, and when young are sparsely pubescent on the 

 upper surface, and below are coated with pale hairs, especially 

 and densely so along the midrib, bright green, eventually sub- 

 coriaceous in texture, fading with tones of yellow, orange and 

 brown : petioles 5—1 5 mm long, margined, pubescent, at least when 

 young : flowers, which open about the middle of April and when 

 the leaves are almost fully grown, i5-i8 mm wide, produced in 

 compound, many-flowered, pilose-pubescent corymbs : pedicels
