In botany, a seed is a plant embryo and food reserve enclosed in a protective outer covering called a seed coat (testa). More generally, the term "seed" means anything that can be sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted.
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.
The Mooloolah River National Park is a nationally protected area located on the Sunshine Coast, Queensland. It covers an area of 830.9 hectares and is bordered by the Mooloolah River to the east, Claymore and Dixon Roads to the west, and the Lower Mooloolah River Environmental Reserve to the south. It is bisected by the Sunshine Motorway with the northern, 161.93 hectare component of the Park being a later addition. The Park was initially vacant crown land prior to national park designation in 1960. Surrounding land uses include livestock grazing, urban development and the campus of the University of the Sunshine Coast. It is the second largest mainland park on the coastal lowlands in South East Queensland after Noosa National Park and represents an example of low-lying coastal floodplain distinctive of the region.
Tribulus terrestris is an annual plant in the caltrop family (Zygophyllaceae) widely distributed around the world. It is adapted to thrive in dry climate locations in which few other plants can survive.
Cryptocarya is a genus of evergreen trees belonging to the laurel family, Lauraceae. The genus includes more than 350 species, distributed through the Neotropical, Afrotropical, Indomalayan, and Australasian realms.
Annona glabra is a tropical fruit tree in the family Annonaceae, in the same genus as the soursop and cherimoya. Common names include pond apple, alligator apple, swamp apple, corkwood, bobwood, and monkey apple. The tree is native to Florida in the United States, the Caribbean, Central and South America, and West Africa. It is common in the Everglades. The A. glabra tree is considered an invasive species in Sri Lanka and Australia. It grows in swamps, is tolerant of saltwater, and cannot grow in dry soil.
Cucumis humifructus, the aardvark cucumber or aardvark pumpkin, is a kind of cucumber from southern Africa, tropical Africa, and Madagascar which fruits underground. It is a prostrate vine up to seven meters in length. It is reliant on the aardvark to eat the fruit in order to spread and re-bury the seeds of the plant. The species was described in 1927, with the name spelled C. humofructus, but this is corrected to C. humifructus following the International Code of Nomenclature for algae, fungi, and plants.
Marah macrocarpa, known as chilicothe, wild cucumber, manroot or bigroot is a species of plant in the genus Marah.
Mikania micrantha is a tropical plant in the family Asteraceae; known as bitter vine, climbing hemp vine, or American rope. It is also sometimes called mile-a-minute vine. It is known as Japani lota in Assam.
The 1950 rainfall records for the Australian states of New South Wales and Queensland reported probably the most remarkable record high rainfall totals ever recorded anywhere in the continent. Averaged over both of these states, 1950 is clearly the wettest year since adequate records became available circa 1885. Queensland recorded a statewide average rainfall of around 1,125 millimetres (44.3 in) as against a mean since 1885 of around 640 millimetres (25.2 in), whilst New South Wales recorded around 930 millimetres (36.6 in) as against an instrumental mean around 520 millimetres (20.5 in). Australia's wettest town, Tully also recorded its highest annual rainfall total in 1950 with 7,925 millimetres (312.0 in).
Enchylaena tomentosa, commonly known as barrier saltbush or ruby saltbush, is a small native shrub of Australia.
The 1911–16 Australian drought consisted of a series of droughts that affected various regions of Australia between the years of 1911 and 1916. Most of the dry spells during this period can be related to three El Niño events in 1911, 1913 and 1914, though rainfall deficiencies actually began in northern Australia before the first of these El Niños set in and did not ease in coastal districts of New South Wales until well after the last El Niño had firmly dissipated and trends toward very heavy rainfall developed in other areas of the continent.
Bryonia alba is a vigorous vine in the family Cucurbitaceae, found in Europe and Northern Iran. It has a growth habit similar to kudzu, which gives it a highly destructive potential outside its native range as a noxious weed. Other common names include false mandrake, English mandrake, wild vine, and wild hops, wild nep, tamus, ladies' seal, and tetterbury.
Cryptostegia is a genus of flowering plants native to tropical Africa and Madagascar. The genus is in the family Apocynaceae.
Aristolochia praevenosa, synonym Pararistolochia praevenosa, is an Australian plant in the birthwort family, native to Queensland and New South Wales. The Richmond birdwing butterfly vine grows in subtropical rainforest in coastal areas north from Wollongbar, in far north eastern New South Wales and adjacent areas in south eastern Queensland. It has been recorded as far north as the Mary River. It also grows in tropical north eastern Queensland, where it is a food plant for the Cairns birdwing butterfly.
Austropuccinia psidii, commonly known as myrtle rust, guava rust, or ʻōhiʻa rust; is a rust native to South America that affects plants in the family Myrtaceae. It is a member of the fungal complex called the guava rust group. The spores have a distinctive yellow to orange colour, occasionally encircled by a purple ring. They are found on lesions on new growth including shoots, leaves, buds and fruits. Leaves become twisted and may die. Infections in highly susceptible species may result in the death of the host plant.
Euclasta gigantalis is a species of moth in the family Crambidae. The female has a wingspan of 45mm.
Eucalyptus raveretiana, commonly known as the black ironbox, is a species of small to medium-sized tree that is endemic to Queensland. It has rough, fibrous or flaky bark on the trunk and larger branches, smooth pale grey bark above, lance-shaped leaves, flower buds in groups of seven on a branched peduncle, white flowers and small, hemispherical fruit.
Onocosiphon suffruticosus, commonly known as the shrubby mayweed, is a flowering plant native to Namibia and the Western Cape and Northern Cape provinces of South Africa. Additionally, it can now be found in France, Australia, and the USA.
Cryptostegia madagascariensis is a species of flowering plant in the family Apocynaceae. It is commonly known as purple rubber vine, is a woody-perennial vine that is native to western and northern Madagascar. It has also been introduced to several tropical and subtropical regions by man, including Puerto Rico and the Virgin Islands. It is very similar to the rubber vine, which is also native to Madagascar. In their area of overlap some hybrids have been observed, which are distinguishable by intermediate flower morphology. In the 1930s a hybrid was also developed for horticultural purposes.
