CAPRIFOLIACEAE 1125 
6. NINTOOA Sweet. 
Shrubby twining vines. Leaves opposite: blades entire, short-petioled or nearly 
sessile. Flowers in pairs each of which terminates an axillary peduncle, accompanied by 2 
foliaceous bracts and 2 small bractlets, the hypanthia distinct. Calyx of 5 slender or subu- 
late sepals. Corolla relatively long: tube slender, not gibbous at the base: limb often 
longer than the tube, 2-lipped, the upper lip 4-lobed, the lower lip narrow. Stamens 5: 
filaments adnate to the corolla-tube. Ovary often 2-celled : style slender. Berries sub- 
globose or slightly elongated, pulpy, distinet. 
1. Nintooa Japónica (Thunb.) Sweet. <A diffusely climbing vine, 2-6 m. long, 
with glabrate or finely pubescent foliage, the bark shreddy. Leaf-blades oblong, ovate or 
orbicular-ovate, 2-5 em. long, thickish, obtuse, acute or short-acuminate, often slightly 
ciliate, rounded or truncate at the base, short-petioled ; petioles pubescent like the 
branches: flowers in pairs terminating peduncles from the upper axils : corolla white or 
pink, turning yellow, pubescent without; tube about 2 cm. long, longer than the recurved 
lips: stamens and style exserted : berries subglobose or oval, 4-6 mm. in diameter, black.

7. LONICERA L. 
Shrubby vines, with trailing or twining stems and shreddy bark. Leaves,opposite :

serted in 2 rows on placentae arising from the inner angles of each cavity. Berry fleshy, 
2-3-celled or by suppression of the septa 1-celled, few-seeded. HONEYSUCKLE.

1. Lonicera Caprifólium L. A twining vine 2-6 m. long, with almost glabrous 
and more or less glaucous foliage, the twigs often pilose. Leaf-blades thickish, oblong, 
oval or obovate, 2-7 cm. long, mostly obtuse, glaucous beneath, the lower ones short- 
petioled, the upper sessile, or the upper one or two pairs connate : flowers in sessile terminal 
clusters : corolla purple without, 3.5-4 cm. long, glabrous within ; tube 2.5-3 cm. long, 
curved, longer than the lips: stamens and style exserted : berries red.  [ L. grata Ait.] 
In thickets and rocky woods, New York to Michigan, south to Georgia and Louisiana. Native of 
Europe. Spring. 
2. Lonicera albiflora T. & G. A shrubby, spreading or partially twining vine, with 
branches 1-3 m. long, the foliage glaucous, usually glabrous. Leaf-blades becoming thick- 
ish, broadly oval, orbicular-oval or obovate, 1.5-4 cm. long, those of the distal pair, or 
typically one pair of bracts connate: flowers in a terminal cluster: corolla 2 ie white 
or yellowish white, 13-16 mm. long, glabrous without ; tube slightly gibbous, pubescent 
within ; lobes of the lips obtuse : filaments glabrous or nearly so: style pubescent : berries 
globular, 8-10 mm. in diameter.
