Introduction

  • This is one of the commonest and most widespread of all Madagascar palms, occurring from sea level up to nearly 1500 m. It is a very attractive single-stemmed species with a slender trunk and leaves with strongly grouped leaflets. In fact it appears uncannily like D. pinnatifrons, and, without staminate flowers and/or fruit it is impossible to tell them apart. The two species can also grow in the same habitat and area, to add to the confusion, but generally, the present species is the smaller and more slender of the two. Young seedlings, however, seem to be easily identified (see notes under D. pinnatifrons). The exposed forms of D. nodifera with very narrow leaflets can be strikingly beautiful. D. nodifera is undoubtedly in cultivation, where it will be impossible to distinguish from D. pinnatifrons until it flowers. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Discussion

  • Although the generic name was validly published by J.D. Hooker in Bentham & J.D. Hooker, Genera Plantarum 3: 877, 909 (1883), the only species mentioned under Phloga is Dypsis nodifera Mart., and under the Code, Article 33.1, Ex. 2, this does not qualify as a new combination. The species bears an extraordinary resemblance to Dypsis pinnatifrons, but can be distinguished by the six stamens (not three) and the ruminate endosperm (not homogeneous, as in the Dypsis). Plants out in the open often have much narrower leaves, and forms with extremely narrow leaves have been split off as var. stenophylla; we believe this is merely an adaptation to bright light, and there are intermediate forms; therefore, we have relegated this variety to synonymy. The flowers were visited by flies in Dransfield et al. JD6436. Overdorff reports that leaves and fruit are eaten by Lemur fulvus and L. rubriventer. Variability can be quite large locally: in Beentje collections at Betampona several trees standing close together were collected, and inflorescences within this population were branched to two or three orders; the prophyll varied in length from 12 to 33 cm. But Beentje & Dransfield 4808 (Mananara Avaratra: Antanambe, Oct. 1994, y.fr.) is so different that it is only tentatively included here. The rachis is slightly longer, but the leaflets are not as tightly grouped and certainly not ovate; they are also less fanned.
    Note. The author of the combination is often cited as Noronha ex Salomon, even by Salomon himself This is not correct: Salomon is the author of the combination, and Noronha had nothing to do with it.
    Note. The name Phloga polystachya was published as a nomen nudum by Noronha in Prodromus Phytologicus, in Du Petit-Thouars, Mélanges de Botanique et des Voyages (1811); there was no description of any kind, but Noronha gives its local name as "Ou Van"; the same local name for this species was given to HB in 1991 Martius, in 1849, cites Phloga polystachya Noronha MSS as a synonym of his own Dypsis nodifera Mart, and Moore (1963) therefore cited the name as Phloga polystachya Noronha ex Mart Hooker (1887) cited the name Dypsis nodifera Mart under the description of Phloga, but did not make the new combination The first to make the combination under Phloga was Baker (1887); it is curious that Baker also described Dypsis polystachya, with a different type, two pages earlier, but did not compare the two Phloga polystachya is an invalid name, as it is a synonym of Dypsis nodifera.

Biology And Ecology

  • Moist forest, on steep or slight mid slopes, or littoral forest on white sand and then on the flat; alt. 5-1440 m. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Conservation

  • Not threatened. Widespread and common. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Common Name

  • Ovana (Betsimisaraka); Bedoda (Betsimisaraka); Sincaré = probably Tsinkiara, a general name for small palms. Tsirika, Tsingovatra (Betsimisaraka; these are fairly general palm names). (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A

Uses

  • Hollowed out stems are used as blowpipes. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)A
