Abstract
Clerodendrum kelli R.Bustam., A.B.Tobias & Ples—a new species of the genus Clerodendrum L. (Lamiaceae) from the montane forests of Carranglan, Nueva Ecija, Luzon Island, Philippines—is described and illustrated. The species shares morphological features that are uncommon for the genus with both Clerodendrum quadriloculare (Blanco) Merr. (purple abaxial leaf surfaces) and C. mindorense Merr. (reduced fruiting calyx lobes), but differs from both in having lax (vs dense/compact) inflorescences bearing flowers with shorter corolla tubes and reddish-pink (vs green or purple) calyces with ovate (vs triangular or lanceolate) lobes. Additionally, a lectotype for C. mindorense is assigned. Preliminary assessment of its conservation status following IUCN guidelines places Clerodendrum kelli in the category of Critically Endangered (CR B1ab(iii)+2ab(iii)).
