'Lonicera hispida' from the website Trees and Shrubs Online (treesandshrubsonline.
Bean’s Lonicera chaetocarpa has been reduced to synonymy with this species, but material in cultivation under the two names exhibits horticulturally significant differences, so we retain Bean’s entries under their original names for the time being, pending a full, revised treatment of Lonicera to be undertaken when funding permits. Bean’s text has been adapted to update the taxonomy.
A deciduous shrub 3 to 5 ft high, with bristly young shoots. Leaves ovate-oblong, rounded or broadly tapered at the base, short-pointed or often blunt at the apex, 11⁄2 to 21⁄2 in. long, about half as wide, hairy on the margins, and more or less so on both surfaces; dark green above, greyish beneath; stalk 1⁄8 in. long. Flowers produced at the base of the young shoots at the end of May; corolla funnel-shaped, about 1 in. long, 5⁄8 in. wide at the mouth, yellow or yellowish white, the tube longer than the lobes. Each pair of flowers is subtended by two roundish ovate membranous bracts up to 1 in. long, edged with bristles; stalk 1⁄3 to 1⁄2 in. long, bristly.
Kingdon Ward introduced a form with softly downy, oblong-lanceolate to oblong leaves with drawn out apices from S.E. Tibet in 1924 (Bot. Mag., t. 9360): this corresponded to the plant described by Royle as Lonicera bracteata (Lonicera hispida var. bracteata (Royle) Rehder ex Airy Shaw).
Native to a broad swathe of Central and East Asia, from the Caucasus to Eastern China, and south to Burma. One of a number of closely related taxa in the Lonicera hispida species complex characterised by their large bracts.
