description
Appearance and leaf
Eucalyptus pendens grows slender in the growth form of the mallee - eucalyptus , this is a growth form that is more shrub -like than tree-shaped , there are usually several trunks that form a lignotuber and reach heights of 2 to 5 meters. The branches hang freely (like a weeping willow ). The bark is smooth and gray or pink in color all over the bush. There are oil glands in the bark.
In Eucalyptus pendens is Heterophyllie ago. On middle-aged specimens, the sitting leaves are lanceolate, curved sickle-shaped, with entire margins and matt gray-green. The leaves on adult specimens are divided into petiole and leaf blade. Your petiole is narrowly flattened or channel-shaped. The leathery and relatively thick leaf blades of the same color on the upper and lower sides on adult specimens are lanceolate, taper towards the base of the blade, have a pointed upper end and can be straight or crescent-shaped. The side nerves, which are barely recognizable, extend from the median nerve at a very acute, acute or obtuse angle. The cotyledons ( cotyledons ) are kidney-shaped.
Inflorescence and flower
On the side of a pedicel-round, narrowly flattened or angular inflorescence stem with a diameter of up to 3 mm in cross section, there are about seven to eleven flowers together in a simple inflorescence . The flower buds are club-shaped and not floured or frosted blue-green. The sepals form a calyptra , which is preserved until flowering ( anthesis ). The smooth, ribbed or warty calyptra is hemispherical, one to twice as long as the striped, warty flower cup (Hypanthium) and as wide as this. The flowers are white or creamy white. The flowering period in Western Australia extends from August to November.
fruit
The fruit is cylindrical or ovoid. The disc is indented, the fruit compartments are included.
Occurrence
The natural range of Eucalyptus pendens is on the west coast of Western Australia , halfway between Perth and Geraldton . Eucalyptus pendens occurs in the independent administrative districts of Coorow , Dandaragan and Moora in the Mid West and Wheatbelt regions .
Eucalyptus pendens grows on white or gray sand soils with laterite gravel . Eucalyptus pendens can be found on slopes of hills, on outcrops and in sandy plains.
Taxonomy
The first description of Eucalyptus pendens was made in 1972 by Ian Brooker , entitled Four new taxa of Eucalyptus from Western Australia in Nuytsia , Volume 1 (3), p 243, Figures 1 AB, 2. The type material has the caption " At 125 miles peg north of Perth on highway between Gingin and Badgingarra. Western Australia (30 ° 14 'S, 115 ° 28' E) 23 July 1969, MIH Brooker 1949. (holo: PERTH, iso: PERTH, FRI, K) “. The specific epithet pendens is derived from the Latin word pendere for hang.
