BOTANICAL STUDIES 



07 



serrate or entire, reflexed after anthesis : stamens 20, the anthers 

 dark purple : fruit, which ripens and falls in September and 

 October, oval or short-pyriform, 7-9™™ thick, io-i2 mm long, the 

 flesh firm : nutlets usually 2-3, rarely more, about 6 mm long, the 

 lateral surfaces nearly plane : hypostyle occupying about half of 

 the ventral angle. 



Crataegus abstrusa grows in woods, mostly in sandy soil, near Tallahassee, 

 Florida (type locality). 



The original specimens, representing flowers {/fyojg) and fruit {H4958) from 

 the same individual, are preserved in the Biltmore Herbarium. 



Crataegus lenis n. sp. 



A shrub or small tree 2-6 m tall with a short trunk sometimes 

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

 bark, or frequently with several stems from the base, the spread- 

 ing and ascending branches forming an oval or irregular, open 

 crown : leaves ovate, oval or suborbicular, the blades i.5-5 cm 

 long, i.5~5 cm wide, mostly pointed at the apex, rounded or con- 

 tracted or on leading shoots truncate or subcordate at the base, 

 the borders serrate and incisely lobed ; they are glabrous, or 

 when young with a few, weak, caducous hairs along the midrib 

 and lower portions of the veins on the upper surface, thin to 

 firm in texture, bright green, fading in autumn with tones of 

 yellow and brown : petioles 7 mm -2 cm long, margined, remotely 

 glandular : flowers i5-i8 mm wide, expanding about the middle 

 of April and when the leaves are more than half grown ; they 

 are produced in simple, glandular-bracteate, 3-7-flowered corymbs 

 which terminate short, leafy branchlets : pedicels and hypan- 

 thium glabrous : sepals triangular-lanceolate, serrate or nearly 

 entire, reflexed after anthesis : stamens 20, the anthers nearly 

 yellow : fruit, which ripens in October, oval or sub-pyriform, 

 6-8 mm thick, 8-1 i mm long, at maturity red or ruddy, the flesh 

 firm : nutlets 2-3, rarely more, 5-6 mm long, the lateral surfaces 

 nearly plane : hypostyle about half the length of the nutlet. 



Cratcegus lenis grows on wooded slopes, mostly in clay soil, near Greenville, 

 Alabama (type locality). 



The type specimens, which represent flowers (Bz/jj) and fruit ( B2/JJ 2 ) 

 from the same tree, are preserved in the Biltmore Herbarium.
