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.[2]
Description
Strongylodon juangonzalezii is a large woody vine (liana) that climbs up to forest canopies. Each leaf is borne on long petioles that split into three leaflets with rounded bases and pointed tips, each around 10 cm (3.9 in) long and 6 cm (2.4 in) wide. The leaves are dark green in color on both the upper and lower surfaces.[2]
The flowers of Strongylodon juangonzalezii point upward. They bloom in dense clusters. They are a vibrant lilac to purple color when young, becoming a striking blue color as they mature. The seed pods are oblong in shape. They split longitudinally as they ripen and mature. The seeds are shiny and maroon in color when fresh, but turn dark brown and papery as they dry. Strongylodon juangonzalezii begins to flower and bear fruits from February to mid-March.[2]
Distribution and habitat
Strongylodon juangonzalezii is a liana. It climbs large trees in disturbed secondary growth forests.[2]
Strongylodon juangonzalezii is endemic to the Philippines (it is the eighth endemic species of Strongylodon in the country). It has only been recorded in four sites in Luzon island. Aside from the Buenavista Protected Landscape, it has also been described from the Masungi Georeserve of Rizal.[1][2][3]
