Conservation
Least Concern (LC).
Distribution
India, Sri Lanka to South China, south to Java and the Philippines, except Borneo. It is further known from isolated populations in the northern part of the Cape York Peninsula in northern Australia and from Guadalcanal in the Solomon Islands (see Map 9).
Ecology
Growing in primary to secondary forest (for instance the Schima-bamboo forest of northern Peninsular Malaysia), beaches or open types of vegetations. Soil: sandy or clay loam, sometimes on granite shale, sandstone or (coral) limestone; 0 – 400 m.
Morphology General Habit
Tree 5 – 18 m long, DBH 10 – 25 (− 50) cm; bark pale brown to white with large thin papery scales
Morphology General Wood
Sapwood pale orange to cream
Morphology Leaves
Leaves opposite, ovate to obovate, (4.5 –) 9 – 34 × 5 – 24 cm, apex acute to acuminate, base cuneate to cordate, margin entire, rarely serrate, membranaceous; hairs stellate or tree-like; venation 4 – 8 main side veins, often triveined from the base, (light) green above, (light green) brownish below; glands whitish, on both upper and lower surface; petioles 1.5 – 8.5 cm long, sub-terete, velutinous to sparsely hairy, green to brown
Morphology Reproductive morphology Flowers
Flowers: calyx 5-lobed, weakly two-lipped, lobes equal, green; flowering calyx 2.5 – 3 × 1.8 – 2 mm; lobes 0.5 – 1 mm long, apex acute; fruiting calyx 3 – 4 mm diam., patent
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 1 – 2.5 mm long, just exceeding the tube when mature, not didynamous; anthers c. 0.2 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla tube 2 – 4 mm long, two-lipped, externally covered with stellate hairs to glabrous, light yellow to (greenish) white or light blue, scented; central lobe of lower lip spathulate to oblong, 1.5 – 2 × 1 – 2 mm, apex acute; side lobe of lower lip oblong, 1 − 1.8 × 0.1 – 1.8 mm, apex rounded; upper lobe spathulate, 1.8 – 2 × 1.8 – 2 mm, apex rounded
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary globose, c. 1 mm diam., glabrous with few stellate hairs at apex, glands absent; style 3.5 – 4.5 mm long, just exserted, stigma 0.1 – 0.5 mm long, apex rounded to acute, yellow
Morphology Reproductive morphology Fruits
Fruit globose, 3 – 6.5 × 3 – 5.5 mm, stellate hairs at apex when young, later glabrous, sometimes with a patch at the apex, black; glands absent or scattered and sometimes concentrated at apex, purple-black when mature, endocarp smooth; seeds four, equally developed when mature.
Morphology Reproductive morphology Inflorescences
Inflorescence 8 – 40 cm long, corymbose cymes, covered with stellate hairs and long simple to shortly branched hairs especially at nodes; bracteoles linear, < 1 mm long
Morphology Twigs
Young twig brown, covered with stellate hairs, with a ridge between petioles, bracts lacking at base
Note
This species greatly varies in leaf size. This is partly due to the various habitats in which this species can grow (Rajendran & Daniel 2002: 289 – 291) and to the fact that the leaves have a strong tendency to decrease in size near the inflorescences. Some of this variation was used to delimit species (Premna pyramidata and P. stellata; Lam 1919) and both names have been placed in synonymy here. Another character that was used in species delimitation is the shape of the calyx lobes (Lam 1919). These can vary greatly during the lifetime of a calyx, resulting in fruiting specimens being giving a different name to flowering specimens. Lam in 1919, expressed his doubt about the validity of this character and the level of recognition that should be given to P. pyramidata and P. tomentosa.
Phenology
Flowering from February to November; fruiting from May to September (rarely February). Flowers reported to be visited by insects, fruits reported to be eaten by birds.
Type
Type: [India] Madras, Klein 1795 (holotype B-Willd).
Vernacular
Peninsular Malaysia: Kapiat or Ara Dumut; Indonesia, Java: Bolang or Gadoengan (Javanese language), Bunglang or Bungbulang (Sundanese language); Sumatra: Djati lauang (Medan); Lajas-lajas (Karo-Batak language) Nandabah (Alas language); West Sumatra: Pisang-pisang or Kajoe-koemit (Malay language); Palembang: Leban tjapo (Malay language); Philippines, Samar: Manaba.

Use
Used medicinally in India (Rajendran & Daniel 2002: 289 – 291) and Peninsular Malaysia; the wood is used for making paddles and house posts. In South Sumatra, the bark mixed with that of a Vitex, pressed and the sap is used against diarrhoea. The ground leaves are used to clean wounds and in the preservation of dried fish and meat (Heyne 1950).

Native to:

Andaman Is., Assam, Bangladesh, Borneo, Cambodia, East Himalaya, India, Jawa, Malaya, Myanmar, Nepal, Nicobar Is., Philippines, Queensland, Solomon Is., Sri Lanka, Sulawesi, Sumatera, Thailand, Vietnam

Extinct in:
