Four basic characteristics make this variation stand out from its counterpart, regular D. prestoniana. One: its mammouth size, (3 and sometime 4 times the size of a regular D. prestoniana) huge even at the juvenile stage, no confusing this palm with a regular D. prestoniana. Second: its much curlier and wider pinnae. Third: its nearly always green, I mean green color. And four: its ease of care to maintain that green color, regular D. prestoniana struggles to keep any semblance of a solid green appearance, (except in Hawaii, once it's well rooted in the ground) often exhibiting a two tone, light green, dark green, striped pinnae (Bill Sanford refers to as the Oreo look}, edric.

A species which was discovered through serendipity: HB was trying to refind Chrysalidocarpus midongensis (now a synonym of D. onilahensis), unaware that that taxon came from a totally different Midongy (a small hamlet in the Itremo Mountains), failed to find it, but spotted this elegant tree on the skyline of a hill. The specific epithet honours Mr. Paul Preston, President of McDonald's Restaurants Limited (UK), who sponsored the four-year Palms of Madagascar fellowship. (J. Dransfield and H. Beentje. 1995).

Conservation: Vulnerable. At present only known from the Midongy area, where numbers do not exceed two hundred. None occurs in a protected area. HB has visited the Mahanoro area, which is nowadays devoid of tree palms. (J. Dransfield and H. Beentje. 1995).

Midongy area; an old collection from Mahanoro. Moist forest; slight slope; clay soils derived from laterite; alt. 50-550 m.

Description

STAMINATE FLOWERS in bud with sepals 1.2-1.3 x 1.2-1.3 mm; petals 1.5-1.8 x 1.3-1.4 mm; stamens 6, 1-seriate, with filaments about 1 mm and narrowly cylindrical, anthers 1-1.2 x 0.4 mm with parallel locules, versatile and dorsifixed; pistillode about 0.8 x 0.3 mm. PISTILLATE FLOWERS with sepals 1.5-2.2 x 1.6-2.4 mm, concave, orbicular, rounded, minutely ciliolate; petals 2-2.6 x 2.1-2.8 mm, broadly obovate with a small apiculus; staminodes 6, 0.4-1 mm high, thin and flat; ovary about 2.5 x 1.8 mm, asymmetrical. FRUIT ellipsoid with rounded apex, 12-15 x 6-8 mm, orange; endocarp fibrous. SEED narrowly ellipsoid, 11-12 x 5-5.5 mm, acute at base, rounded at apex, with homogeneous endosperm with slight marginal undulations. (J. Dransfield and H. Beentje. 1995)/Palmweb. Editing by edric.

Quite distinct from other large solitary species with grouped pinnae by its long and interfoliar inflorescence with densely puberulous rachillae, and homogeneous endosperm. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Culture

Cold Hardiness Zone 9b

Comments and Curiosities

Four basic characteristics make this variation stand out from its counterpart, regular D. prestoniana. One: its mammouth size, (3 and sometime 4 times the size of a regular D. prestoniana) huge even at the juvenile stage, no confusing this palm with a regular D. prestoniana. Second: its much curlier and wider pinnae. Third: its nearly always green, I mean green color. And four: its ease of care to maintain that green color, regular D. prestoniana struggles to keep any semblance of a solid green appearance, (except in Hawaii, once it's well rooted in the ground) often exhibiting a two tone, light green, dark green, striped pinnae and spear (Bill Sanford refers to as the Oreo look).

A species which was discovered through serendipity: HB was trying to refind Chrysalidocarpus midongensis (now a synonym of D. onilahensis), unaware that that taxon came from a totally different Midongy (a small hamlet in the Itremo Mountains), failed to find it, but spotted this elegant tree on the skyline of a hill. The specific epithet honours Mr. Paul Preston, President of McDonald's Restaurants Limited (UK), who sponsored the four-year Palms of Madagascar fellowship. (J. Dransfield and H. Beentje. 1995)/Palmweb.

Conservation: Vulnerable. At present only known from the Midongy area, where numbers do not exceed two hundred. None occurs in a protected area. HB has visited the Mahanoro area, which is nowadays devoid of tree palms. (J. Dransfield and H. Beentje. 1995)/Palmweb.
