INFLORESCENCE infrafoliar, branching to 3 orders, arching with pendulous rachillae; peduncle 22-26 cm, strongly curved, distally about 4 x 3 cm, with scattered scales; prophyll 41-54 cm, borne at 6-9.5 cm above the base of the peduncle, about 14 cm wide, persistent, pale brown abaxially, chestnut-red adaxially; peduncular bract inserted at about 14 cm above the base of the peduncle, deciduous; rachis 47-50 cm, first order branches 14-20, 15 x 9 mm across, glabrous or with minute scattered scales, all axes green; rachillae cream-coloured, pendulous, 13-53 cm, 3-4 mm across, glabrous; triads spaced to dense, sunken; rachilla bract obtuse. STAMINATE FLOWERS only known in young bud. PISTILLATE FLOWERS in young fruit with sepals 2.8-3.7 x 4-5.2 mm, ciliolate; petals 4.5-5 x 5.6-6 mm; staminodes about 1.2 mm long. Young FRUIT 4-5 x 5-5.5 mm. (J. Dransfield and H. Beentje. 1995)/Palmweb. Editing by edric.

This taxon resembles D. pilulifera but is distinct by the regular leaflets and the presence of scattered scales on the leaflets. (J. Dransfield and H. Beentje. 1995)/Palmweb.

A majestic, tristichous palm (the leaves are in three ranks). Although the material is incomplete, this is clearly a distinct taxon. The name derives from the local name. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Culture

Sunny, moist, but well drained position. Filtered light when very young. Cold Hardiness Zone: 10a

Comments and Curiosities

The name tsaravoasira apparantly means "good with salt" in the local language. It thus doesn't really need to be said that the palm heart is eaten.

Conservation: Endangered. Only known from three sites, two of which are under agricultural pressure; numbers within the populations are low, and we have seen less than thirty altogether. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Uses: Palm-heart edible and highly esteemed.

This Dypstery is a difficult one to keep straight, but lets try anyway.

An important point to start with is that the main palm that was introduced as Dypsis tsaravoasira is the legendary "Orange Crush," and definitely not Dypsis tsaravoasira. "Orange Crush" had been identified as Dypsis pilulifera for years, but it has lost it's name D. pilulifera to the infamous D. sp. 'Jurassic Park' which is now D. pilulifera. Also one of the palms that was introduced as Dypsis sp. 'cerecea' and later misidentified as Dypsis nauseosa, is now confirmed by John Dransfield as the real Dypsis ampasindavae, and Dypsis tsaravoasira is now a new type all together, D. ampasindavae, and Dypsis tsaravoasira are two totaly different species, and no onger are associated.

Having said that, would you believe that there is still some unanswered questions and doubt? More than one Palmateer is not sold on this ID. Bill has posted the following pics of two different Dypsis sp. 'ceracea.' The first two being the one JD earlier identified as Dypsis tsaravoasira, and the last two, suggested by Bill to possibly be the real Dypsis tsaravoasira. Maybe we can get some better pics of these two.

Bo Lundkvist has supplied the following pics of the Dypsis tsaravoasira confirmed by JD.
