Capsule loculicidal, the valves in opening bearing the partitions and separating 

 from the persistent placentiferous axis; calyx-lobes valvate in the bud. 

 Capsule ovoid-pyramidal; flowers in terminal panicles of secund racemes; anther- 

 cells opening longitudinally from the apex to the middle; leaves deciduous. 



4. Oxydendrum. 



Capsule oblong; flowers in axillary fascicles; anthers opening below the apex by 

 2 oblong pores; leaves persistent. 5. Lyonia. 



Fruit drupaceous; flowers in terminal panicles; anthers bearing a pair of reflexed awns 

 on the back, each cell opening at apex anteriorally by a terminal pore; leaves per- 

 sistent. 6. Arbutus. 

 Ovary inferior; fruit baccate; flowers axillary, racemose or solitary ; anther-cells terminating

1. ELLIOTTIA Ell. 



A glabrous tree or shrub, with slender terete branchlets, scaly buds, and fibrous roots. 

 Leaves petiolate, oblong or oblong-obovate, acute at the ends or occasionally rounded at 

 apex, entire, thin, dark green and glabrous above, pale and villose below, particularly on 

 the thin yellow midrib and obscure forked veins; deciduous; petioles slender and flattened, 

 with an abruptly enlarged base nearly covering the small axillary buds. Flowers perfect, 

 on slender elongated pedicels, in erect terminal elongated racemose panicles, with minute 

 acute scarious caducous bracts and bractlets; calyx short, tubular, puberulous, dark red- 

 brown, 4-toothed, the broad apiculate teeth erose on the margins and imbricated in the 

 bud; petals 4, imbricated in the bud, spatulate-linear, sessile; stamens 8, hypogynous, shorter 

 than the petals, filaments broad, flattened; anthers oblong-ovoid, the cells callous-mu- 

 cronate, free at the apex of the spreading lobes, opening from above downward; disk much 

 thickened, fleshy; ovary sessile, subglobose, 4-lobed, 4-celled, concave at apex; style elon- 

 gated, slender, gradually enlarged and club-shaped above and incurved at apex; stigma 

 3-5-lobed, smaller than the thickened end of the style; ovules numerous in each cell, at- 

 tached on the inner angle of a tumid piacenta, ascending, anatropous. Fruit unknown. 



Elliottia with a single species is confined to the southern United States. 



The genus is named in honor of Stephen Elliott (1771-1830), the distinguished botanist 

 of South Carolina.
