The genus Hoya (Family: Apocynaceae) has more than 500 species,
comprising mainly of epiphytes and geographically distributed in South America,
Southeast Asia, Indo-Malesia and Australian regions. Most of the species are cultivated
for their ornamental, aromatic and showy flowers. Philippines is one of the countries
with the highest diversity of Hoya species. As seed setting is very rare in most of the
species, it necessitated the development of conservation strategies through ex situ
conservation methods using vegetative or micropropagation techniques. Present chapter
provides detailed information on the traditional uses, phytoconstituents, conservation
status and micropropagation studies of the ornamental and medicinally important genus
Hoya.
