*Pothos* sp. Riau is an unidentified true *Pothos* in the Araceae, separate from the commonly sold “pothos” in *Epipremnum*. The Riau label should be treated as a locality or collection name from Sumatra, Indonesia, rather than a formal species name. The plant produces slender climbing stems with narrow, elliptic green leaves held close to the stem. Nodes produce roots when kept against moss, bark, cork, or a humid background surface, and the plant is best grown vertically rather than as a loose trailing vine.
