Syzygium australe

Higher Taxonomy
Family: MyrtaceaeView DescriptionDichotomous Key

Habit: [Subshrub] shrub, tree, trunk bark smooth or scaly; glands 0 or embedded in epidermis. Leaf: opposite or alternate, persistent, generally glandular when young. Inflorescence: generally axillary, raceme, panicle, cyme, or flowers 1. Flower: generally bisexual, parts in 4s, 5s, generally +- white; hypanthium exceeding ovary or not; stamens generally many; ovary [rarely superior to] inferior, 2--5(18)-chambered; placentas axillary, just below top, or basal, ovules few to many, generally in 2--many series. Fruit: berry, capsule, nut. Seed: 1--many; coat membranous to +- leathery or hard, bony; embryo starchy or oily (of great taxonomic importance).
Genera In Family: 100 genera, +- 3500 species: many species tropical America, Australasia, fewer Africa, southern Asia; economically important for timber (Eucalyptus), spices (Syzygium aromaticum (L.) Merr. & L.M. Perry, cloves; Pimenta dioica (L.) Merr., allspice), edible fruits (Psidium guajava L., guava; Acca sellowiana (O. Berg) Burret, pineapple guava), many orns (Eucalyptus, Melaleuca, several other genera). Note: Apparently of Gondwanan origins; tropics, subtropics, Mediterranean climates. Chamelaucium uncinatum Schauer, Luma apiculata (DC.) Burret, Melaleuca citrina (Curtis) Dum.Cours., Myrtus communis L., Syzygium australe (Link) B. Hyland are waifs.

Genus: SyzygiumView Description 

Habit: Shrub, tree, generally glabrous. Leaf: opposite, persistent, papery or leathery. Inflorescence: cyme, panicle, or raceme, terminal, axillary, sometimes on older stems. Flower: calyx lobes, petals 4 [(5)]; hypanthium prolonged above ovary, base often long-acuminate; ovaries chambers generally 2, each few--many-ovuled. Fruit: berry. Seed: 1--2(5), seed coat membranous; embryos sometimes many, distorted; cotyledons separate, thick, planoconvex.
Species In Genus: +- 500 species: old world tropics. Etymology: (Greek: joined, from paired structures of some species)

Syzygium australe (Link) B. Hyland
Stem: branchlets weakly compressed, 4-winged or -ribbed near tips, wings merging in pairs to form pocket near next lower node; older branches smooth, +- cylindric, bark tan, flaking. Leaf: blade obovate or elliptic, 3--9 cm, 1.2--3.2 cm wide, 2.2--2.8 × longer than wide; base +- narrowly wedge-shaped; apex acute or abruptly acuminate, with mucro. Inflorescence: terminal and in upper leaf axils, cyme, axis 10--15 mm; flowers 3--7; bracts falling before flowers open, leaving prominent scar. Flower: bud 6--10 mm, club-shaped; bracteoles ephemeral; calyx lobes 4, in subequal pairs, 2--3 mm, 2--4 mm wide, ovate, margins scarious, apex bluntly acute to rounded; petals round, 3--5 mm diam, white, margins scarious, tip rounded; stamens 100--150; styles 7--24 mm. Fruit: 14--23 mm, +- spheric or elliptic, red or purple. Seed: generally 1, spheric; cotyledons >> embryonic stem.
Ecology: Rare in disturbed urban riparian areas; Elevation: < 50 m. Bioregional Distribution: SCo (San Diego Co.); Distribution Outside California: southeastern Australia. Note: Often cultivated in California; sometimes confused with Syzygium paniculatum Gaertn. (winged or ribbed branchlets 0, twig pockets 0; seed often with many embryos), also commonly cult, but evidently not escaped, in California.
