Common Name: MYRTLE FAMILY 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. eFlora Treatment Author: Leslie R. Landrum, except as noted Scientific Editor: Thomas J. Rosatti.
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. Etymology: (Greek: joined, from paired structures of some species) eFlora Treatment Author: F.R. Barrie & Leslie R. Landrum Reference: Hyland 1983 Austral J Bot Suppl Ser 9:1--164
Syzygium australe (Link) B. Hyland
WAIF 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.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
