13. UNIFLOIUE. 



29. unifldra, Moench (C. parvifolia, Ait. C. tomen- 

 tosa, Eggleston, not Linn. C. fldrida, Loud.). Dense, 

 low shrub, with numerous slender spines, rarely spine- 

 less, 3-8 ft. : Ivs. on short not glandular petioles, cuneate, 

 obovate or oblong-obovate, irregularly or doubly cren- 

 ate-serrate, pubescent on both sides, at length gla- 

 brous above, J^-1H m - long: fls. J^in. across, 1-3-fld. 

 corymbs; calyx pubescent, with large serrate lobes: fr. 

 pyriform or globose, yellow, % in. across, with 3-5 

 stones. May, June. Ga. and Ala. to Fla. S.S. 4:191. 



30. Vailiae, Brit. Shrub, to 12 ft., with slender 

 straight spines: Ivs. oval or ovate, acute, cuneate at 

 the base, crenate-serrate and often slightly lobed, at 

 maturity glabrous and lustrous above, pubescent 

 below, J^-lj/2 in- long: fls. ^in. across, in 2-6-fld., 

 pubescent corymbs; calyx-lobes glandular-serrate: fr. 

 globose, M m - across, dull red, with 3-5 stones. May;

14. FLAV.<. 



31. flava, Ait. Tree, to 20 ft. : branches wide-spread- 

 ing, with thin nearly straight spines: Ivs. broadly obo- 

 vate or elliptic, acute or nearly rounded, cuneate at base, 

 coarsely and doubly serrate, on vigorous shoots usually 

 slightly lobed, the teeth tipped with red glands, at 

 maturity puberulous only on the veins below, about 2 

 in. long; petioles glandular, short: corymbs few-fld., 

 slightly villous; calyx-lobes glandular-serrate; fls. %in. 

 across; stamens 20, with purple anthers: fr. ovoid, 

 dark orange-brown, J^in. long, with dry and mealy 

 flesh and 5 stones. April; fr. in Oct. Ga. and Fla. 

 S.S. 13 : 693. The true C. flava is not in cult.; the plant 

 now cult, as C. flava is quite different and is apparently 

 not very closely related to this species; it has so far not 

 been found growing wild in E. N. Amer., though it was 

 apparently intro. from the southern states. As it has 

 not yet been determined to which species it belongs, it 

 may be enumerated here as var. lobata, Lindl. Shrub 

 or small tree: Ivs. ovate or obovate, cuneate at the base, 

 acute, crenately serrate and often slightly lobed, at 

 maturity pubescent on the veins beneath, 1-2 in. long: 

 corymbs pubescent, few-fld.; stamens 10: fr. pyriform, 

 green or reddish with hard flesh, and 3-5 stones. B.R. 

 23:1932, 1939. G.C. III. 27:404. Tender. 



32. aprica, Beadle. A shrub or small tree, some- 

 times to 20 ft., with spreading branches and slender 

 zigzag branchlets armed with thin straight spines 1-1^ 

 in. long: Ivs. broadly obovate or oval, acute or rounded 

 at the apex, narrowed into the short petiole, serrate 

 usually only above the middle and often slightly lobed, 

 with gland-tipped teeth, pubescent on both sides while 

 young, at maturity glabrous, dark yellow-green and 

 thickish, %-lH in. long: fls. %in. across, in 3-6-fld. 

 compact pubescent corymbs; calyx-lobes glandular- 

 serrate: fr. globose, ^in. across, dull orange-red, with 

 3-5 stones. May; fr. Oct. Va. to Ga. and Tenn. S.S. 

 13:698. This species has proved hardy at the Arnold 

 Arboretum.
