 Florida, especially Apalacliicola. 



§ 4. Pieris. Corolla from ovate-urceolate to cyliiulraceous, 5-toothecl : calyx 

 of 5 nearly distinct and eai-ly oj^en sometimes herbaceous sepals : filaments nar- 

 row, usually pubescent orciliate, 2-setose or 2-toothed at or below the apex (these 

 teeth or awn-like appendages spreading or recurved, rarely obsolete) : anthers 

 oblong, awnless: dorsal sutures of the 5-angular capsule with more or less of 

 a thickened ridge (sometimes separating in dehiscence) : placentiE usually borne 

 about the middle of the columella and of the cells: seeds scobiform or oblong 

 and with a loose thin coat. — Pieris § 1 & § 4, Benth. & Hook. 1. c. — Original 

 Pieris, Don, is Asiatic, with racemes chiefly terminating leafy branches ; and the 

 seeds pendulous. The two American, of subsection Maria (Pieris § Maria, Benth. 

 & Hook.), bear the flowers in axillary umbels or fascicles, the pedicels scarious- 

 bracteate and bracteolate at base ; and the placentae as low as the middle of the 

 columella ; the seeds therefore in all directions. All combine into one subgenus 

 in structure of flower, capsule, and bisetose filaments. 



* Leaves thick-coriaceous aud evergreen: sepals thickisli aud rigid, purplish: flowers honey- 

 scented, in early spring. 



A. nitida, Bartr. (Fetter-bush.) Very glabrous, 2 to 6 feet high, and with acutely 

 triangular branches : leaves Myrtledike, rigid, bright green, very shining above, punc- 

 ticulate beneath, ovate to lanceolate-oblong, acuminate, entire, the minutely revolute edge 

 bordered by an intramarginal nerve : flower-clusters in the axils of the persistent leaves of 

 the preceding year : corolla ovoid-cylindraceous with contracted orifice (3 or 4 lines long, 

 from white to rose-red) : filaments nearly glabrous, bearing the setiform small appendages 

 close to the summit : style abruptly fusiform-thickened above the middle : capsule ovoid- 

 globose, little exceeding the calyx. — Bartram, Cat. & in Marsh. Arbust. (1785) 8; AValt.

* * Leaves almost membranaceous, deciduous: flowers (late spring or summer) consequently on 



leafless branches of the previous J'ear, in the manner ol Zenuhia: sepals thinner, larger, and 

 nearly foliaceous, deciduous with the leaves! {Leucoihat § Maria, DC.) 



A. Mariana, L. (Staggek-bush.) Glabrous or slightly pubescent, 2 to 4 feet high : 

 leaves oblong or oval, obtuse or acute at both ends, entire, loosely veiny (1 to 3 inches 

 long) : fascicles of nodding flowers racemose on naked shoots : corolla cylindraceous-cam- 

 panulate with slightly narrowed orifice, white or pale rose-color (almost half inch long) : 

 filaments hairy outside ; their very small setose appendages below the summit, occasionally 

 obsolete or wanting: capsule ovate-pyramidal, truncate at the contracted apex; the pla- 

 centa; low down. — Sims, Bot. Mag. t. 1579; Duham. 1. c. t. 37; Gray, Man. ed. 5, 296.

§ 5. Lyonia. Corolla from globular to urceolate, pubescent or glandular : 

 calyx 5- (rarely 4-) cleft ; the valvate lobes early open, short : filaments fiat, 

 pubescent ; these and the short anthers both destitute of appendages or awns : 

 capsule as in the preceding section, i. e. with ribs at the dorsal sutures which are 

 more or less separable iu dehiscence : placentae on the apex of the columella 

 and at the top of the cells : seeds all pendulous, narrow, scobiform, having a loose
