Hoya undulata

Hoya undulata S.Rahayu & Rodda sp. nov. is an epiphytic, glaborous  climber with white latex in all vegetative parts. The leaves of this species form domatia, specialised structures harbouring ants, previously only observed in Hoya mitrata Kerr and Hoya darwinii Loher.

Stems slender, internodes very variable in length, from 0.5 cm in the parts of the vine forming domatia, to 20 cm long in climbing stems,, green with darker spots; adventitious root sparsely produced along the stem. Leaves petiolate; petiole broader than stem, light green to purple; lamina dimorphic, the first type ovate, obovate or oblanceolate, usually almost flat, located along climbing stems, the second type almost round to elliptic, usually convex and forming domatia.

The specific epithet 'undulata; refers to the characteristic undulate leaf margin.

 

The genus was named in Modern Latin in honor of English gardener and botanist Thomas Hoy (c. 1750-1822).
