Habitat and Distribution

Bangladesh, China Southeast, India, Mauritius, Nepal, Pakistan, Sri Lanka, and the West Himalayas. Phoenix sylvestris is common, wild or cultivated, in the plains of India and Pakistan. Phoenix sylvestris thrives from the plains to the coast in low-lying wastelands, scrub forest and areas that have been disturbed or are prone to periodic or seasonal inundation with water, causing water-logging.

Description

Solitary palm. Stem to 10 - 15 (20) m tall, without leaf sheaths about 20 - 30 cm in diam., with persistent, diamond-shaped leaf bases; stem base with mass of roots. Crown hemispherical, with more than 50 leaves. Leaves about 1.5 x 4 m long; leaf sheath reddish-brown, fibrous; pseudopetiole 40 - 50 cm long x 3 - 5 cm wide at base; acanthophylls closely inserted, arranged in several planes, about 13 - 18 on each side of rachis, conduplicate, yellow-green, very sharp, 4 - 14 cm long; leaflets irregularly fascicled, arranged in several planes, about 80 - 90 on each side of rachis, concolorous, greyish-green, often waxy, very sharp, 18 - 35 x 1.2 - 2.4 cm. Staminate inflorescences to 25 per plant, erect, not extending far beyond prophyll; prophyll coriaceous, bright orange internally when young, splitting first adaxially (side adjacent to trunk), 25 - 40 x 6 - 15 cm; peduncle 20 - 30 x 1.2 - 2.2 cm; rachis 13 - 18 cm long with numerous, congestedly arranged rachillae, each 4 - 16 cm long. Staminate flowers white-yellow, musty-scented; calyx a deep cupule to 2 - 2.5 mm high with 3 poorly defined lobes; petals 3 (rarely 4), apices obtuse, slightly hooded, 6 - 10 x about 3 mm; anthers 3 - 4 mm long. Pistillate inflorescences erect, arching on fruit maturation; peduncle green and upright, becoming golden-orange and arching on fruit maturation, to about 90 x 2 cm; prophyll papery, short, splitting twice between margins, about 24 x 5 cm; rachillae arranged in irregular horizontal whorls, about 50 - 60 in number, yellow-green in colour, about 8 - 34 cm long. Pistillate flowers creamy-white, about 40 - 50 mostly restricted to distal half of rachilla; calyx cupule 1.5 - 2.5 mm high; petals 3 - 4 x 4 - 5 mm. Fruit obovoid, 15 - 25 x 12 mm, ripening from green to orange-yellow, with mesocarp moderately fleshy and astringent. Seed obovoid with rounded apices, 15 - 20 x 7 - 10 mm; embryo lateral opposite raphe; endosperm homogeneous. (S.C. Barrow. 1998)/Palmweb. Editing by edric.

Phoenix sylvestris was first described as Katou-Indel by Rheede (1678 - 1703) in Hortus Indicus Malabaricus, upon which Linnaeus' description of Elate sylvestris in Musa Cliffortianus (Linnaeus 1736) was entirely based. The description of Elate sylvestris in Species Plantarum (Linnaeus 1753), comprised two elements: Palma dactylifera minor humilis sylvestris fructu minori, Hin Ind. Zeylaneus of Hermann (1698) in Paradisi Batavi Prodomus 361, and Palma sylvestris malabarica, folio acuto, fructu prunifacie in Historia Plantarum 1364 (Ray 1686 - 1704). The latter was based entirely on Rheede's Katou-indel. Roxburgh (1832), in transferring Elate sylvestris to Phoenix, failed to acknowledge these two elements and based Phoenix sylvestris solely upon Katou-indel. The name Phoenix sylvestris is thus correctly typified by Katou-indel of Rheede's Hortus Indicus Malabaricus. Hamilton (1827) recognised the two elements in Elate sylvestris but it was Martius (1823 - 53) in Historia Naturalis Palmarum who formally separated them. Palma dactylifera minor humilis sylvestris fructu minore, Hin Ind. Zeylaneus of Hermann was included by Martius in P. pusilla Gaertn., and Katou-indel was taken to refer only to P. sylvestris Roxb.
