| Apium prostratum subsp. howense | |
Apium prostratum subsp. howense is a flowering plant in the carrot family native to Australia's Lord Howe Island. The epithet howense derives from the name of that island. [1]
It is a perennial herb, tufted, trailing and aromatic when bruised, with stems growing to 30 cm long. The pinnate leaves are 20–170 mm long. The tiny flowers are white to pinkish. The fruits are 1.5–2 mm across. [1]
The subspecies is endemic to Australia’s subtropical Lord Howe Island in the Tasman Sea. There it is fairly common in sand pockets and cracks in coralline rocks on the shoreline, within the splash zone. [1] Joseph Maiden's 1889 book 'The Useful Native Plants of Australia records how 'Apium australe' could be used as a culinary vegetable and also refers to it as 'Australian Celery". [2]
Apium is a genus of about 20 species of flowering plants in the family Apiaceae, with a subcosmopolitan distribution in Europe, Asia, Africa, South America and Australia. They are medium to tall biennials or perennials growing up to 1 m high in the wet soil of marshes and salt marshes, and have pinnate to bipinnate leaves and small white flowers in compound umbels. Some species are edible, notably Apium graveolens, which includes the commercially important vegetables celery, celeriac and Chinese celery. Apium bermejoi from the island of Menorca is one of the rarest plants in Europe, with fewer than 100 individuals left.
Eucalyptus viminalis, commonly known as the manna gum, white gum or ribbon gum, is a species of small to very tall tree that is endemic to south-eastern Australia.

Eucalyptus gunnii, commonly known as cider gum, is a species of small to medium-sized tree endemic to the island of Tasmania, Australia. It has mostly smooth bark, lance-shaped to egg-shaped adult leaves, flower buds in groups of three, white flowers and cylindrical to barrel-shaped fruit.
Atriplex cinerea, commonly known as grey saltbush, coast saltbush, barilla or truganini, is a plant species in the family Amaranthaceae. It occurs in sheltered coastal areas and around salt lakes in the Australian states of Western Australia, South Australia, Tasmania, Victoria and New South Wales.
Casuarina glauca, commonly known as the swamp she-oak, swamp oak, grey oak, or river oak, is a species of Casuarina native to the east coast of Australia. It is found from central Queensland south to southern New South Wales. It has become naturalised in the Everglades in Florida where it is considered a weed.
Apium prostratum, commonly known as sea celery, is a variable herb native to coastal Australia and New Zealand. The leaves are variable, with toothed leaflets, and a celery like aroma. The tiny white flowers occur in clusters.
Leptospermum polygalifolium, commonly known as tantoon, jellybush or yellow tea tree, is a species of shrub or tree of the family Myrtaceae that is endemic to eastern Australia, including Lord Howe Island. It has thin bark, elliptical leaves, white flowers arranged singly on short side shoots and fruit that remain on the plant for a few years.
Trophis scandens subsp. megacarpa is a flowering plant in the mulberry family. The subspecific epithet comes from the Greek mega ("big") and carpos ("fruit"), with reference to the larger fruits in this subspecies.
Hymenophyllum howense is a fern in the family Hymenophyllaceae. The specific epithet refers to the locality of occurrence.
Cryptocarya gregsonii, commonly known as native blackbutt, black plum or laurel, is a flowering plant in the laurel family. The specific epithet honours Jesse Gregson of Newcastle, New South Wales, a botanical friend of Maiden.
Coprosma huttoniana is a flowering plant in the family Rubiaceae. The specific epithet honours Ian Hutton, the Lord Howe Island based naturalist who discovered the plant and recognised it as a new species.
