Lowest part of the carpel containing the ovules; later developing into the fruit.
(sect.) Subdivision of a genus.
Generally an elongated structure arising from the ovary bearing the stigma at its tip.
(subsp.) Taxonomic rank for a group of organisms showing the principal characters of a species but with significant definable morphological differentiation. A subspecies occurs in populations that can occupy a distinct geographical range or habitat.

Shrub or tree, 3-10 m. Leaves 8-18 x 2.5-6 cm, broadly oblanceolate to obovate, base rounded, lower surface glabrous except for persistent punctulate hair bases. Flowers scented, 5-12, in a lax truss; calyx 1-3 mm; corolla 7-lobed, pale rose, sometimes fading white, open- to funnel-campanulate, nectar pouches lacking, 55-70 mm; stamens 14-16, filaments glabrous; ovary and entire style stalked-glandular. Flowering May-July. Royal Horticultural Society (1997)

Distribution  China C, S & E

Habitat 600-2,300 m

RHS Hardiness Rating H5

Conservation status Least concern (LC)

An evergreen shrub, ultimately 10 to 12 ft high, usually less in this country and of wide-spreading habit; branches stout, soon glabrous. Leaves oblong, with a tapering, rounded, or heart-shaped base, abruptly pointed; 4 to 8 in. long, 2 to 312 in. wide, quite glabrous on both surfaces, pale green above, slightly glaucous beneath; stalk stout, purplish, 12 to 1 in. long. Flowers fragrant, produced in May, somewhat loosely arranged in terminal clusters of eight to twelve; each blossom is 212 to 3 in. across, of a lovely blush tint on opening, becoming paler afterwards. Calyx so small as to be scarcely discernible. Corolla seven- (or rarely eight-) lobed, flattish; stamens fourteen to sixteen, much shorter than the corolla, glabrous; ovary and base of style glandular. Bot. Mag., t. 5596. (s. and ss. Fortunei)

Native of eastern China; discovered by Fortune in Chekiang province in 1855 and introduced to Glendinning’s nursery by means of seeds he collected the same autumn. Plants raised from these seeds were auctioned in 1859 and the species was named in that year by Lindley, but it was first properly described in 1866, in the Botanical Magazine, from a flowering specimen received from Mr Luscombe of Coombe Royal, Devon. The plate is a poor one and does not show the glands on the pedicels, style, and outer surface of the corolla characteristic of the species, though they are shown on the type specimen at Kew from which the original painting was made.

R. fortunei is a beautiful rhododendron, and is of interest as the first hardy species of ‘true’ rhododendron (as distinct from azalea) received from China.

Of the first-generation hybrids of R. fortunei the best known are those with R. griffithianum (the famous Loderi grex), R. thomsonii (Luscombei grex), and R. campylocarpum (grexes Gladys and Letty Edwards). These and others are described in the section on hybrids. In that section see also ‘Lavender Girl’ and ‘Duke of York’.

From the Supplement (Vol. V)

subsp. discolor (Franch.); Chamberlain R. discolor Franch.; R. mandarinorum Diels; R. kirkii Hort.; R. houlstonii Hemsl. & Wils.; R. fortunei var. houlstonii (Hemsl. & Wils.) Rehd. & Wils. – Differing from the typical subspecies only in its relatively narrower, oblanceolate leaves and not clearly demarcated from it either in this respect or geographically (Rev. 2, pp. 234-5 and Map 65). A distinguishing character given in Species of Rhododendron is the later flowering season of R. discolor. However, this applies only to the Wilson introduction from western Hupeh, and with the inclusion of R. houlstonii in subsp. discolor it is no longer true constantly if it ever was, since, as represented in British gardens by the Wilson introduction, R. houlstonii flowers even earlier than typical R. fortunei. These plants could be distinguished as R. fortunei subsp. discolor Houlstonii group.

subsp. discolor (Franch.) D.F.Chamb.

R. discolor Franch.
R. houlstonii Hemsl. & E.H.Wilson
R. kwangfuense Chun & Fang

Leaves oblanceolate, 2.8-4× as long as broad.

Awards AM 1921 (Messrs Wallace, Tunbridge Wells) as R. discolor; flowers white, tinted pink externally. AM 1922 (Hon. H.D. McLaren, Bodnant) as R. discolor; flowers pale pink, with a dull crimson blotch. AM 1974 (Crown Estate Commissioners, Windsor) to a clone ‘John R. Elcock’, as R. houlstonii; flowers purple, yellow in throat, with some spots in upper part. FCC 1922 (Royal Botanic Gardens, Kew) as R. discolor; flowers white, tinted pink externally. AM 1981 (R.N.S. Clarke, Borde Hill) to a clone ‘Random Harvest’, as R. houlstonii, from an E.H. Wilson collection; flowers in trusses of 10-12, corolla white, tinged pink, with some yellow-green in upper throat. AGM 1993

The two subspecies have partially overlapping distributions and apparently also overlap morphologically. R. fortunei can be confused with R. decorum but may be distinguished by the glabrous stamens. In cultivation it often has reddish petioles. R. fortunei has been much used as a parent in the generation of garden hybrids.

subsp. fortunei

Leaves obovate, 1.8-2.5× as long as broad.
