AQUIFOLIACEAE 731 



petals white, obovate or oblong-obovate, 3-3.5 mm. long, obtuse : stamens included : fruit 

 ovoid, 6-7 mm. long, dry and indehiscent, 3-5-winged, rarely nearly as broad as long, the 

 faces and wings strongly wrinkled. \_Cliftonia ligustrina Spreng. ] 



In pine-land swamps, Georgia to Florida and Louisiana. Winter and spring. 



Family 6, AQUIFOLIACEAE DC. Holly Family. 



Usually evergreen shrubs or trees, with a watery sap. Leaves alternate, 

 without stipules : blades simple, entire or toothed, sometimes spiny. Inflores- 

 cence normally cymose. Flowers perfect or polygamous, regular. Calyx of 

 4-6 j)ersisteut imbricated sepals. Corolla white or greenish, of 4-6 deciduous 

 imbricated petals which are alternate with the sepals and often united at the 

 base. Androecium of 4-6 stamens inserted at the base of the corolla, alternate 

 with the petals, all fertile. Filaments erect, shorter than the petals. Anthers 

 introrse, the sacs opening lengthwise. Gynoecium a compound pistil. Ovary 

 2-6-celled (rarely with more cavities). Stigma commonly sessile, with as many 

 lobes as cavities in the ovary. Ovules 1-2 in each cavity, suspended, anatropous. 

 Fruit a drupe with 4-8 horny or crustaceous nutlets. Seeds with a mem- 

 branous testa. Endosperm fleshy, copious. Embryo cylindric and straight, 

 or globose. \_Ilicaceae Lowe.]
