villose early in the season, becoming nearly glabrous, 3-6 mm. in length; 

 leaves at the end of vigorous shoots broad-obovate to suborbicular, 

 occasionally slightly lobed with short rounded lobes, more coarsely serrate, 

 up to 3 cm. in diameter. Flowers opening the middle of April, 1 cm. in 

 diameter, nearly sessile, solitary (on the single specimen in this herbarium), 

 the short pedicels thickly covered with long matted white hairs; calyx 

 broad-obconic, villose, the lobes slender, acuminate, nearly entire or lacin- 

 iately glandular-serrate above the middle, villose; stamens 20; anthers 

 rose color; styles 5. Fruit obovoid, gradually tapering to the base, 1-1.2 

 cm. long, 8-9 mm. in diameter, the calyx prominent with a short tube, a 

 broad deep cavity pointed in the bottom, and spreading and reflexed much 

 enlarged lobes; flesh thin, dry and mealy; nutlets 5, rounded at apex, 

 gradually narrowed and acute at base, rounded and grooved on the back, 

 6-7 mm. long and 3 mm. wide, the narrow dark hypostyle extending nearly 

 to the base. 



A shrub 1.5-2 mm. high, with very slender branchlets covered early 

 in the season with matted pale hairs, dull red-brown and slightly pubes-

Florida. Leon County, upland woods in sandy soil near, Tallahassee^ 

 T. G. Harbison Nos. 5710 (type) and 5710a, April 15 and October G, 1920. 



This species generally resembles C. uniflora Moencli, the type of the 

 Group, which differs from the Tallahassee plant by its usually more pubes- 

 cent leaves, yellow anthers, subglobose rarely slightly obconic fruit with 

 a more enlarged calyx. It is named for Henry B. Croom, a native of 

 Newbern, North Carolina, who for many years visited his plantations in 

 western Florida every winter, and in 1833 discovered Torreya on the 

 bank of the Appalachicola River, and who wrote and published papers on 

 the flora of the southern states. 



Crataegus Victorinii (§ Macracanthae), n. sp. 



Leaves ovate to oval or obovate, rounded and short-pointed or acute 

 at apex, abruptly concave-cuneate at base, often slightly and irregularly 

 lobed with acuminate lobes, and sharply doubly serrate usually only above 

 the middle with straight teeth; nearly fully grown when the flowers 

 open and then glabrous witli the exception of a few hairs on the upper side 

 of the midrib, and at maturity thin, glabrous, dull dark green on 

 the upper surface, paler on the lower surface, 3.5-4 cm. long and 2.5-3 

 cm. wide, w r ith a stout midrib and prominent veins impressed above; 

 petioles stout, narrow, wing-margined to the middle, glabrous, 1-1.5 cm. 

 in length; leaves on vigorous shoots obovate, rounded at apex, more acutely 

 cuneate at base, lobed with longer acuminate lobes, 4.5-5 cm. long and 3-4 

 cm. wide. Flowers opening early in June, 1.5 cm. in diameter, on long 



slender pedicels in wide 10-25
