Description

Slender forest undergrowth palm to 2 m tall, solitary and clustering. STEM about 7 mm in diam. (not exceeding 3 cm, fide Jumelle). LEAVES about 6 in the crown (7-8, fide Jumelle); sheaths 6.5 cm long, about 7 mm in diam., covered in caducous chocolate-coloured scales; petiole 8-15 cm long, about 2.5 mm wide near base, covered in a thick layer of caducous pale brown scales; rachis 9-10 cm; leaflets 3-4 on each side of the rachis, ± regularly arranged, drying pale green, up to 2.5 cm distant, the longest to 25 cm long, about 4-12 mm wide, mostly composed of a single fold, both surfaces with scattered punctiform scales, abaxially with broad bands of caducous brown scales. INFLORESCENCE interfoliar, in bud much shorter than the leaves, but one dead inflorescence axis suggesting eventually as long as leaves (to 45 cm fide Jumelle), branching to 1 order only; peduncle 21 cm; prophyll to 8 x 0.4 cm, membranous; peduncular bract exceeding prophyll by 9.5 cm, otherwise similar (exceeding prophyll by 23 cm fide Jumelle); rachis about 5 cm (8-12 cm, fide Jumelle) with rather dense brown scales; rachillae probably about 14, about 2 cm long, about 0.5 mm in diam., rather sparsely scaly, triads about 0.5 mm apart in immature inflorescence, rachilla bract entire, inconspicuous. STAMINATE FLOWERS in very young bud, all parts at an early state of development; stamens 3 antepetalous. (J. Dransfield and R. Govaerts. 2006)/Palmweb. Editing by edric.

The need for the new name, Dypsis anovensis, is a consequence of the inclusion of Neophloga in Dypsis. Dypsis anovensis is known only from its type. The combination of slender, linear leaflets and small sparsely branched inflorescence is paralleled by D. cookei from high elevation forest on Marojejy; however, the leaflet texture of the latter is different and there are consistently more leaflets on each side of the rachis, that dry dark rather than pale green. Some of the dimensions mentioned by Jumelle suggest that he had more mature inflorescences at hand than the one preserved on the type sheet in P. (J. Dransfield and R. Govaerts. 2006)/Palmweb.

Culture

Warm, sheltered and moist. Cold Hardiness Zone: 10a

Comments and Curiosities

Conservation: Presumed extinct. Not seen for more than eighty years. Most of the forest has disappeared from the Anove River mouth. (J. Dransfield and R. Govaerts. 2006)/Palmweb.
