Genera

[ Back to top ]

Acanthophoenix

Acanthophoenix is a monoecious genus of in the palm family from the Mascarene Islands in the Indian Ocean, where they are commonly called palmiste rouge. A genus long in flux, three species are currently recognized, though unsustainable levels of harvesting for their edible palm hearts have brought them all to near extinction in habitat. They are closely related to the Tectiphiala and Deckenia genera, differing in the shape of the staminate flower. The name combines the Greek words for "thorn" and "date palm". [more]

Archontophoenix

Archontophoenix is a plant comprising six palm species that are native to eastern Australia. They are tall, slender and unbranched. [more]

Areca

Solitary or small clump-forming palms, stem annulate, slender, smooth, unarmed, 0.5-25 cm in diameter. Leaves pinnate, pinnae mostly narrow, often with 2 or more principal ribs, long acuminate, rather short stiff. Base of leaf stalk usually forming a prominent shining swollen crown shaft. Leaflets thin, often confluent. Inflorescence much branched, borne at the base of the crown shaft. Female flowers in triads at the base of the rachillae, male flowers small, variously arranged on the upper part of rachillae; sepals small; petals much large, obliquely lanceolate, valvate; stamens 3-6 (-12-24) or more; anthers basifixed, erect; female flowers on the base of the rachillae larger than the male, sepals and petals imbricate, petals acute; ovary one-chambered, stigmas 3, very short; ovule one, basal, erect. Fruit ovoid or oblong, exocarp fleshy, fibrous. Seeds with truncate base, embryo basilar.[1] [more]

Dypsis

Trunks erect, clustered, less than 15 cm diam., clustering, erect, with conspicuous nodal rings, unarmed, occasionally branching near base. Leaves: leaf bases unarmed, yellowish, forming distinct crownshaft; blade pinnate [undivided], unarmed; plication reduplicate; segments lanceolate, evenly spaced, strongly ascending; apices acuminate. Inflorescences axillary below crown of leaves, paniculate, with 3 orders of branching; prophyll small; peduncular bracts caducous, tubular. Flowers unisexual, sessile, in triads of 1 pistillate flower flanked by 2 staminate flowers. Staminate flowers: sepals 3, imbricate, free; petals 3, briefly connate basally, valvate; stamens 6, free; anthers dorsifixed; pistillode present. Pistillate flowers: sepals 3, imbricate, free; petals 3, imbricate, free; staminodes 6, minute; pistil 1; ovules 1; stigmas 3. Fruits drupes, ellipsoid; exocarp yellow, smooth; mesocarp fleshy; endocarp thin, fibrous, terete in cross section. Seeds ovoid; endosperm homogeneous; embryo subbasal; eophyll 2-cleft; segments lanceolate.[2] [more]

Euterpe

In , Euterpe (E?t??p?) + t??pe?? terpein (to please)) was one of the Muses, the daughters of Mnemosyne, fathered by Zeus. Called the "Giver of delight", when later poets assigned roles to each of the Muses, she was the muse of music. In late Classical times she was named muse of lyric poetry and depicted holding a flute. A few say she invented the aulos or double-flute, though most mythographers credit Marsyas with its invention. The river god Strymon impregnated Euterpe; her son Rhesus led a band of Thracians and was killed by Diomedes at Troy, according to Homer's Iliad. [more]

Heliconia

Plants: pseudostems erect, in groups of [1--]5--50. Leaves: petiole long [short or nearly absent], base of blade unequal on either side of midrib. Inflorescences terminal, erect [pendent], raceme of cincinni; cincinni spiral [2-ranked]; cincinnal bract ± enclosing each cincinnus, brightly colored, leaflike. Flowers each subtended by membranous floral bract. Fruits blue [rarely red or orange] at maturity. Seeds surrounded by stony, roughened endocarp (pyrenes). x = 12.[3] [more]
