TREES AND SHRUBS. 



CAEYA FLOBIDANA, Saeg. 



Carya floridana, n. sp. 



Leaves from five- to seven-, usually five-, foliate, with slender petioles scurfy-pubescent when 

 they first appear, soon becoming glabrous, and from 1.5 to 2 decimetres long ; leaflets lanceolate 

 to oblanceolate, long-pointed and acuminate at the apex, unsymmetrical and rounded or cuneate 

 at the base, serrate with remote cartilaginous teeth, sessile or the terminal leaflet occasionally 

 short-petiolulate ; when they unfold thickly covered with rufous pubescence, soon becoming en- 

 tirely glabrous, and at maturity conspicuously reticulate-venulose, the three upper leaflets from 

 9 to 10 centimetres long and from 2.5 to 5 centimetres broad, and about twice larger than those of 

 the lower pairs. Staminate inflorescence long-pedunculate, scurfy pubescent, from 2.5 to 3 centi- 

 metres in length, produced at the base of shoots of the year from the axils of bud-scales, and also 

 from the axils of leaves ; pistillate inflorescence not seen. Fruit without wings or very slightly 

 winged at the sutures, obovate, gradually narrowed and rounded at the apex, cuneate at the base, 

 slightly four-angled, covered with yellowish brown scales, about 2.5 centimetres long and 2 centi- 

 metres in diameter ; involucre from 2 to 2.5 millimetres thick, splitting freely to the base, usually 

 by two sutures and to the middle by a third suture, the fourth usually remaining closed ; nut sub- 

 globose, usually slightly flattened, rounded or occasionally acute at the base, acute at the apex, 

 slightly ridged to the base, pale reddish brown, the reticulate veins deeply impressed, about 2 

 centimetres long and 1.8 centimetre wide, with a shell from 2 to 3 millimetres thick, and a small 

 seed. 



A tree, from 18 to 25 metres high, with a trunk sometimes 4 decimetres in diameter, covered 

 with slightly ridged dark gray-brown close bark, spreading branches forming a broad head, and 

 slender branchlets coated when they first appear with rufous scurfy pubescence, soon becoming 

 puberulous, and at the end of their first season glabrous, rather bright red-brown and marked by 

 numerous pale lenticels. Scales of the winter-buds valvate, thick, covered with yellow-brown 

 scurfy scales, the lateral sessile or stipitate ; terminal buds not collected. Flowers in February. 

 Fruit ripens in June. 



Eastern Florida: in sandy soil in the Indian River region, Volusia County, common : Eldred, 

 B. K. McCarty, June 1, 1911 (type), T. G. Harbison, March, 1913; near Georgiana, Merritt's 

 Island, W. M. Canby, February 16, 1889; sandy woods near Rock Ledge, W. M. Canby, Feb- 

 ruary, 1889. 



Carya floridana differs from all described species of the genus in the production of some of the aments of staminate 

 flowers from the axils of leaves ; from the other species with valvate bud-scales it differs in the number of leaflets which 

 are only five, while in the other species of this section they vary from seven to eleven, thirteen or fifteen. This is also 

 the only species of this group with obovate fruit ; the sessile or nearly sessile terminal leaflet and the cartilaginous teeth 

 of the leaflets are unusual. C. S. S.
