Dischidia imbricata
Dischidia imbricata is a plant in the genus Dischidia native to Southeast Asia from Vietnam to Borneo and Java. Like Hoya imbricata, Dischidia imbricata is a shingling plant that, as it grows epiphytically, clings closely to the host plant and may even have leaves that are completely flat like roof shingles.
