Agapetes is a genus of evergreen, mostly epiphytic shrubs in the family Ericaceae (order Ericales), rarely terrestrial trees, usually bearing a swollen rootstock. Native to the eastern Himalayas through southwestern China, Indochina, and Southeast Asia, the genus comprises about 80 species — 53 of them in China (17 endemic) — with many more names published historically (The Plant List accepted 147 of 245 published names as of 2018). Plants are semi-climbing to shrubby, grown ornamentally for their pendulous bunches of red, tubular flowers that bloom over a long season. Leaves are spirally arranged, subopposite, or pseudoverticillate, with entire or serrate margins. The 5-merous flowers appear axillary, solitary or in racemes, corymbs, or fascicles; the corolla is typically red (rarely white or yellow), sometimes with dark zig-zag bands, and may be tubular, urceolate, or campanulate. Ten stamens roughly equal the corolla in length, and the inferior ovary is divided into 10 pseudolocules by false partitions. The fruit is a globose, succulent to nearly dry berry with a persistent calyx. The genus was published by George Don in 1834, building on work by David Don, with Agapetes setigera as the lectotype. Most species belong to the same lineage as many Southeast Asian–Malesian Vaccinium; New Guinea and Southwest Pacific species formerly placed here are now in Paphia.
Etymology
The genus name Agapetes derives from the Greek ἀγαπητός (agapetos), meaning 'beloved'.
Distribution
The genus is native to the eastern Himalayas, extending through southwestern China and Indochina into Southeast Asia. China is the center of diversity with 53 species, 17 of which are endemic. It is cultivated in cool temperate to subtropical climates elsewhere.
Ecology
Agapetes species are predominantly evergreen epiphytic shrubs (rarely terrestrial trees), typically with a swollen rootstock. They grow in climates ranging from cool temperate to subtropical and are adapted to montane and forested habitats across their Himalayan–Southeast Asian range.
Cultivation
Agapetes is grown as an ornamental for its long-blooming pendulous red tubular flowers. Propagation is from cuttings. In the United Kingdom, the cultivar Agapetes 'Ludgvan Cross' has received the Royal Horticultural Society's Award of Garden Merit. It thrives in cool temperate to subtropical climates.
Taxonomy Notes
The genus was validly published by George Don in 1834 (General History of the Dichlamydeous Plants 3: 862), based on previous work by David Don. The lectotype species is Agapetes setigera D. Don ex G. Don, designated in 1871. Historical synonyms include Caligula Klotzsch, Corallobotrys J. D. Hooker, Desmogyne King & Prain, and Pentapterygium Klotzsch. Most Agapetes species belong to the same lineage as many Southeast Asian–Malesian Vaccinium species. Species formerly placed in Agapetes from New Guinea and the Southwest Pacific have been transferred to Paphia Seemann.
