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.

Common Name: EUCALYPTUS, GUM TREE Habit: Tree, shrub. Stem: generally erect; bark shedding, smooth, or persistent near base (occasionally) or throughout, rough; twigs generally round. Leaf: juvenile generally opposite, horizontal, sessile, +- cordate, entire, glaucous; adult generally alternate, vertical, petioled, +- lanceolate, entire, glandular, glabrous, generally same color on both sides. Inflorescence: axillary, (1)3--many-flowered, stalked umbel or panicle-like cluster of such umbels. Flower: perianth (generally, entirety of calyx lobes, petals) fused into bud cap in bud, bud cap shed at flower; stamens many, in several series, generally all fertile, white (yellow, red, pink); ovary chambers 3--6, fused to hypanthium. Fruit: capsule, thick-walled, woody, generally smooth, generally dehiscing at top. Seed: generally 1--3 mm, wind-dispersed. Etymology: (Greek: true cap, for bud cap) Note: World's largest flowering plants, some > 100 m; Eucalyptus pulverulenta Sims excluded, cultivated only. eFlora Treatment Author: Matt Ritter Reference: Brooker 2000 Austral Syst Bot 13:79--148
Eucalyptus citriodora Hook.
NATURALIZED Stem: 20--35 m, straight, slender; bark smooth, shed in irregular pieces, occasionally spotted, white or golden when first exposed, tan in age. Leaf: 10--20 cm, 1--2 cm wide, lanceolate, lemon-scented. Inflorescence: panicle of 3--5-flowered umbels. Flower: hypanthium 5--6 mm, hemispheric, > bud cap; bud cap generally beaked; stamens white. Fruit: < 15 mm, urn-shaped; valves included. Ecology: Uncommon. Disturbed coastal areas; Elevation: generally < 200 m. Bioregional Distribution: SCo; Distribution Outside California: native to northeastern Australia. Flowering Time: Dec--May Note: Commonly cultivated in California; treated by some as Corymbia citriodora (Hook.) Hill & Johnson (Hill & Johnson 1995 Telopea 6:185--504).

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.
