SPIDER GUM, BUSHY YATE


Higher Taxonomy
Family: MyrtaceaeView DescriptionDichotomous Key
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.

Genus: EucalyptusView DescriptionDichotomous Key


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.

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.
