Strongylodon juangonzalezii, commonly called JC's vine or purple jade vine, is a species of leguminous perennial liana (woody vine) endemic to the tropical forests of the Philippines. It bears a cluster of large flowers that are initially lilac to purple in color, but become a striking blue as they mature.
Taxonomy.
"Strongylodon juangonzalezii" was first described in 2016 from specimens collected from the Buenavista Protected Landscape of Mulanay, Quezon Province. It is named after Juan Carlos Tecson Gonzalez, a professor of zoology and the then director of the UPLB Museum of Natural History. The generic name comes from Greek "strongylos" ("round") and "odontos" ("tooth-like"), in reference to the teeth-like shape of the flowers.

"Strongylodon juangonzalezii" begins to flower and bear fruits from February to mid-March.
