back : berries globular.

7. Lonicera flava Sims. A twining vine 1-3 m. long, with glabrous and sparingly 
glaucous foliage. Leaf-blades broadly oval, broadly ovate or oblong, or rarely obovate or 
elliptic, the upper 1, 2 or 3 pairs connate, obtuse or acutish, chartaceous-margined, 
gradually narrowed or sometimes cordate at the base, the lower ones short-petioled : flow- 
ers in terminal clusters, fragrant: corolla bright orange-yellow, glabrous without ; tube 
fully 20 mm. long, glabrous within, barely gibbous, about twice as long as the lips: fila- 
ments and style glabrous, exserted : berries subglobose or oval, 6-7 mm. long. 
On rocks or in rocky soil, North Carolina, South Carolina, Georgia and Alabama. Spring. 
8. Lonicera sempérvirens Ait. A commonly evergreen twining vine 1-6 m. long, 
with glabrous or sparingly pubescent and glaucous foliage. Leaf-blades leathery, oval or 
oblong or sometimes obovate, lanceolate or linear-lanceolate, 3-9 cm. long, obtuse or apic- 
ulate, glaucous and sometimes softly pubescent beneath, the upper pair or several pairs 
connate, dark green, glabrous or nearly so above: clusters forming terminal interrupted 
spike-like panicles: corolla scarlet or yellow, 3-4 cm. long, glabrous ; tube slightly dilated 
upward; lobes 5, spreading, nearly equal: stamens and style scarcely exserted : berries 
clustered, about 6 mm. long, scarlet. 
In sandy soil, often on river banks, Connecticut to Nebraska, Florida and Texas. Summer to fall.
