gins dentate or shallowly lobed near the apex ; they are glabrate 

 or somewhat pubescent on the lower surface at maturity, and 

 when young are lucid or bright green and slightly pubescent on 

 the upper surface, especially along the midrib, pale beneath, and 

 with conspicuous tufts of tomentum in the axils of the veins, 

 which, together with the midrib, are coated with pale hairs, firm to 

 subcoriaceous in texture, bright green, fading in autumn with 

 tones of yellow, orange and brown : petioles 7 mm -2 .5 cm long, mar- 

 gined, glandular, pubescent, at least when young : flowers i5~2o mm 

 wide, opening about the 20th of March and when the leaves are 

 almost fully grown ; they are disposed in simple, 3-5-flowered 

 corymbs which terminate leafy branchlets or fascicles of leaves : 

 pedicels and hypanthium tomentose : sepals 4-5™™ long, glan- 

 dular-serrate, reflexed after anthesis : stamens 20, the anthers 

 light yellow : fruit, which ripens in August, pyriform or oblong- 

 pyriform, io-i4 mm thick, about i.5 cm long, at maturity yellow or 

 orange, blotched or cheeked with red, the flesh succulent : nutlets 

 mostly 3, 8-io mm long, the lateral surfaces nearly plane : hypostyle 

 6-7 mm long. 



Cratcegus vicana is well represented in herbaria by the collections made by- 

 Mr. A. H. Curtiss {No. 6617) from individuals growing in a vacant lot in Tavares, 

 Lake county, Florida. From the specimens gathered by Mr. C. L. Boynton at 

 Tavares, and representing flowers {B4010) and fruit {B4010 2 ) from the same 

 individual, the description has been drawn. 



The type specimens are preserved in the Biltmore Herbarium.
