備註: 原產地菲律賓 ,為不少雜交種的其中一種親本。本變種跟原種分別為: 所有萼裂片都化成葉狀萼片,而原種只有一塊萼裂片都化成葉狀萼片。 Mussaenda philippica var. aurorae is unique in having five enlarged calyx lobes (3.5–7 x 2–5.5 cm) Exclusive of calycophylls, the variety closely resembles M. philippica var. philippica in vegetative and reproductive structures. The variety aurorae has been one of the parent taxa of the quite different and colorful Philippine Mussaenda cultivars. The variety aurorae is endemic to Laguna, a province in central Luzon, and has also been collected in nearby Manila. This variety is cultivated in Los Banos or is known from secondary forests, on clay, humid soils, and at altitudes ranging from 100 to 250 m.s.m. Shrubs 1.5–3 m tall; young twigs puberulous. Leaf blades 8–16 x 3.2–8.5 cm, puberulous on both surfaces, margins ciliate, apex not conduplicate; secondary in 8 to 10 pairs; petioles 0.7–1.5 cm, sparsely to densely pubescent; stipules triangular, 3.5–7 x 2–5 mm at the base, abaxially with sparse indument only at the base; apex bifurcate about half of length the stipule lobes not diverging. Inflorescences puberulous; bracts entire or bilobed, 3.5–4 x 1–1.7 mm, densely pubescent underneath. Flowers with the pedicels 1–2.5 mm; calyx tubes 3.5–4 mm, pubescent; calyx lobes recurved, all developing into calycophylls; colleters 2 or 3 pairs per lobe; calycophylls 3.5–7 x 2–5.5 cm, puberulous along nerves of both surfaces, margins ciliate, base cuneate; calycophyll stalks 0.6–1 cm, densely pubescent; corolla tubes 1.5–2.3 cm long, with tuft of trichomes surrounding the opening; corolla lobes 4–6 x 4–4.5 mm; apex recurved, filiform apical appendages 1–1.5 mm; anthers 6 mm in short-styled flower morphs; pollen diameters to 15.75 um; ovary 3.5–4 3 1.5–2 mm, style 3–4 mm in short-styled flower morphs, stigma 3.5–4 mm in short-styled flower morphs Alejandro, G.J.D., Meve, U. & Liede-Schumann, S.
