6. Lonicera purpusii Rehder

Map 1426

Plants shrubs 1.5–2.5 m tall, the main stems erect or ascending, self-supporting. Twigs glabrous or inconspicuously hairy with minute, scurfy hairs, the pith solid. Winter buds narrowly ovoid, glabrous except for the finely hairy margins of the scales. Leaf blades 3.5–9.5 cm long, 1.5–5.0 cm wide, elliptic to ovate-elliptic, angled or tapered at the base, angled or tapered to a sharply pointed tip, the upper surface glabrous, the undersurface (and margins) sparsely to moderately pubescent with stiff, more or less appressed hairs along the midvein, not glaucous, but the undersurface light green. Flowers in pairs, 1 or 2 in the axils of the leaves on previous years growth (second-year wood), each pair sessile, the 2 bracts each 3–9 mm long, fused at the base, ovate to ovate-triangular, hairy along the margins, the pair of bractlets on opposite sides of each flower somewhat longer than the ovary, usually fused at the base, oblong-ovate to nearly circular. Calyces glabrous, the lobes 0.1–0.5 mm long, broadly semicircular or the margin appearing merely undulate. Corollas 12–18 mm long, somewhat zygomorphic, divided 1/2 or slightly more than 1/2 of the way to the base into 5 more or less spreading lobes of about equal length, the lower lobe with deeper sinuses than those between the other 4 lobes, the tube noticeably swollen or pouched on the lower side near the base, white, turning cream-colored or pale yellow after pollination or with age. Stamens and style exserted from the corolla, about as long as the corolla lobes, the style glabrous. Ovaries fused to about the midpoint. Fruits 6–10 mm long (oblong-ellipsoid), red. January–February.

Introduced, uncommon, known thus far from a single site in Cape Girardeau County (artificially derived hybrid between two Asian species; introduced in Missouri). Disturbed mesic upland forests.

This is an artificial hybrid between two Chinese species, L. fragrantissima Lindl. & Paxton and L. standishii Jacques. Its leaves are semievergreen. The intensely fragrant flowers appear very early in the season. The first Missouri collections were made by Mark Basinger in 2000 at a remnant woodlot within the Cape Girardeau city limits.
