BILTMORE B0TAX1CAL STUDIES 



at maturity firm in texture, glabrous or glabrate, the borders ser- 

 rate and incisely lobed : petioles 1-2. 5 cm long, margined : flowers 

 i2-i5 mm wide, expanding about the first of April and when the 

 leaves are nearly grown; they are bcrne in compound many- 

 flowered, pilose-pubescent coombs, the lower branches of which 

 are axillary : pedicels and hypanthium sparsely pilose : sepals 

 3~4 mm long, narrowly lanceolate, entire or minutely serrate, pubes- 

 cent on the inner surface, at least at flowering time : stamens 

 normally 20, 4~6 mm long : fruit globose, 5~7 mm in diameter : nut- 

 lets 3-5, about 5 mm long, the lateral surfaces nearly plane and the 

 back either smooth or with shallow grooves : hypostyle three- 

 fourths as long as the ventral angle. 



Cratcegus subviridis was found in low woods and bordering watercourses 

 near Chattahoochee, Florida (type locality), in which region the species is not 

 uncommon. 



The type material, consisting of flowers {B20J6) and fruit (B20/6 2 ) from the 

 same tree, is preserved in the Biltmore Herbarium. 



Crataegus interior n. sp. 



A small tree about 5 m tall with a trunk i-2 dm in diameter, 

 dividing 1-2 m from the base, the ascending branches forming an 

 oval, symmetrical crown, or frequently a large, much-branched 

 shrub : bark dark gray or brownish, flaky ; of the branches 

 smooth, the growth of the season glabrous, reddish-brown marked 

 by small pale lenticels : spines stout, i~3 cm long on the smaller 

 branches, chestnut-brown or gray : leaves ovate, ovate-lanceolate 

 or oblong, the blades 2-6 cm long, i-4 cm wide, acute or acuminate 

 at the apex, rounded or abruptly contracted at the base ; they are 

 pubescent on the upper surface along the midrib and largest veins 

 and in the groove of the petiole at the time of unfolding, and on 

 the lower surface bear tufts of pale hairs in the axils of the veins, 

 becoming in age glabrous or glabrate, the borders serrate and 

 deeply incised : petioles 5 mm -2. 5 cm long, margined: flowers about 

 I5 mm wide, appearing when the leaves are nearly grown and 

 expanding during the last of April or first of May ; they are 

 borne in compound, many-flowered, glabrous corymbs, the lower 

 branches of which arise from the axils of leaves : pedicels and 

 hypanthium glabrous: sepals 2-3. 5 mm long, entire or slightly ser-
