Habitat and Distribution

Saribus jeanneneyi is Endemic to the region of Prony, Southeastern New
New Caledonia. Photo by Dr. Jean-Christophe Pintaud, Royal Botanic Gardens, Kew/Palmweb.
Caledonia. Vallicole forest, dense, wet, steep substratum, in shallow soil on rocky scree and ultramafic substrate; alt. 200 m. A single specimen of this species is located in the Far South of Grande Terre. Considered extinct, it was rediscovered (one mature specimen only) in the region of Prony. there is one in cultivation now, grown from seed it has flowered for the first time (December 2004), at the age of 18. New information acquired; recently relocated in three very small populations.

Description

A solitary palm, up to 10 m. high with a smooth trunk 15 cm. in diam., Flared at the base, revealing a collar of roots. Crown holds 15 leaves, glabrous, arranged in staggered corona, petiole 1.35 m. long and 3.5 cm. wide, rounded bottom, flat or slightly hollow top, blade about 1 m. radius, regularly divided into 60 - 64 leaflets welded together at the bottom, then free over a length of 45 cm., at the top bifid of 4 - 7 cm. Phenology: Inflorescences glabrous, the young wine-colored, green adults, 1.4 m. long, well-branched in the distal part, with flowers glabrous. Fruit large, globose, 3.5 cm. in diam. Black - purple at maturity. (From the French)

Moderate, solitary, pleonanthic, hermaphroditic, palm. Stem erect, smooth, ringed with conspicuous leaf scars. Leaves induplicate, briefly costapalmate, neatly abscising; sheath disintegrating into a network of fine rusty-brown fibres; petiole elongate, adaxially flat to ridged, abaxially rounded, margins distally smooth, basally with short recurved spines in juvenile plants, smooth in adults, adaxial hastula short, rounded, abaxial hastula lacking; blade stiff, regularly divided to or beyond the middle into single-fold, briefly bifid, lanceolate, spreading segments, glabrous on both surfaces, midribs and intercostal ribs prominent, transverse veinlets conspicuous. Inflorescences interfoliar, branched to 4 orders, branches angled; peduncle very short, flattened; prophyll not seen, inserted above the base; peduncular bracts lacking; rachis very short, deeply divided into 3 elongate first-order branches, each branch bearing l peduncular bract below 2 unilateral second-order branches subtended by tubular, chartaceous bracts, bifid and flaring at the apex; proximal two second-order branches flattened, adnate to the first-order branch, subsequent second-order branches not subtended by tubular bracts, not adnate; bracts not evident at bases of rachillae; rachillae short, ± clustered at the ends of second-order branches, bearing rather distant cincinni of 3 flowers basally and solitary flowers distally. Flowers sessile, ebracteolate; calyx tubular, adnate basally to the receptacle, with 3 short free lobes; petals 3, briefly connate basally, valvate and adaxially hollowed distally, persistent; stamens 6, inserted at throat of the corolla, filaments erect, briefly connate and adnate to the petals basally, anthers erect, subglobose, sagittate, introrse; gynoecium globose-trilobate, trilocular, triovulate, carpels distinct in ovarian region, connate through styles, style slender, short, awl-shaped, stigma dot-like, ovule inserted basally, anatropous. Pollen ellipsoidal, occasionally slightly asymmetric; aperture a distal sulcus; ectexine tectate, aperture margin similar; infratectum columellate; longest axis 23–24 µm [1/1]. Fruit large, 1-seeded, globose, with apical stigmatic remains; epicarp smooth, purplish, mesocarp fleshy to fibrous near endocarp, endocarp woody, rounded on one side, keeled on the opposite side, laterally elongate and attenuate basally. Seed globose, erect, hilum basal, raphe orbicular, adjacent to hilum, endosperm homogeneous, deeply hollowed out basally with a large, erect intrusion of seed coat; embryo eccentrically apical. Germination remote-tubular; eophyll entire, oblanceolate, toothed distally. Cytology not studied. (Dransfield, J., Uhl, N.W., Asmussen, C.B., Baker, W.J., Harley. M.M. and Lewis, C.E.) Editing by edric

Differs from most other Old World members of the Trachycarpeae in lacking any kind of armature on the petioles. The endocarp is unlike that of any other member of the group. In habit, it resembles Livistona, and in the branching of the inflorescence, it is much like Saribus woodfordii. (Dransfield, J., Uhl, N.W., Asmussen, C.B., Baker, W.J., Harley. M.M. and Lewis, C.E.)

Culture

Warm, sheltered and moist when young, but becoming very resiliant as they get older. Seed apparantly germinates readily, but the young plants can be difficult to establish. Cold Hardiness Zone: 10b

Comments and Curiosities

Old name-Pritchardopsis jeanneneyi

Anatomy: Leaf with coryphoid midrib, irregular 2-layered adaxial hypodermis, and indistinct or lacking palisade layers.

Uses: The apex is edible and destructive exploitation has resulted in near extinction.
