and thin cellular-reticulated testa : flowers (small and white) racemose or fascicled: 

 bracts minute and deciduous. Lyonia, Nutt. Gen. i. 2G6 ; Benth. & Hook. Gen. 

 ii. 587. 



* Lepidotc-scurfy, not pubescent : flowers fascicled in the axils of persistent coriaceous leaves. 



A. ferruginea, Walt. Low shrub, or taller and arborescent : leaves rigid, cuneate-obo- 

 vate, rhombic-obovate, or cuneate-oblong, entire, with revolute margins ( 1 or 2 inches long), 

 smooth and shining above, or obscurely lepidote when young, grayish or fcrrugincous-

 two forms are pretty well marked, viz. var. arborescens, with narrower less reticulated 

 leaves, usually crowded; and vnr.fruticosa, with sparser leaves conspicuously reticulated, 

 mostly cuneate-obovate or rhomboidal. To this belongs A. rliomboidulis, " Veill." in Duham.

9. OXYDENDRUM, DC. SORREL-TREE, SOUR-WOOD. (Composed of 

 oil's, sour, and dsvdQOv, tree, from the acid foliage. Oxydcndron, Benth. & Hook., 

 but DeCandolle's form follows the analogy of Epidendrum.) A single species, 

 with Peach-like foliage : fi. summer. 



O. arboreum, DC. Tree 15 to 40 feet high: leaves membranaceous and deciduous, 

 oblong or lanceolate (4 to 6 inches long), acuminate, serrulate, glabrous, or at first glaucous,

10. LEUC6THOE, Don. (Mythological; the name of one of the fifty 

 daughters of Nereus.) North and South American and Japanese shrubs, of 

 various habit ; with entire or serrulate leaves, and racemose chiefly white flowers.

 least mainly), Benth. & Hook. Gen. ii. 584, 586. (Ac/arista of Don is evidently 

 founded on the Mauritius and Bourbon species, the section Agauria, DC., genus 

 Agauria, Benth. & Hook., to which are added S. American species, all or chiefly 

 belonging to Leucothoe.) 



1. EULEUCOTHOE. Calyx not bracteolate, 5-parted ; the divisions usually
