definition | Distribution: Species within the Amaranthaceae family are distributed world-wide in
tropical and warm temperate regions. This family currently consists of c. 70 genera
and c. 1000 species. In Australia specifically there are 18 genera with c. 200 species;
c. 160 of these are endemic, 10 native and 27 introduced. Description: Species within this family are ephemeral, annual, biennial or perennial herbs, shrubs and rarely climbing shrubs. For more details regarding the description of species within this family please see: https://profiles.ala.org.au/opus/foa/profile/Amaranthaceae Pollen Morphology: The pollen produced by the species in this family are spherical and between 15-25um in diameter. There are many pores (>15, panto-porate) that are small (1.5-2.5um) and are scattered all over the pollen grain. The surface texture of the pollen varies between species, with some being slightly granular (scabrate) and others have a smooth or very fine mesh surface texture. Note Chenopodiaceae was formerly considered a separate family. Taxa of that classification has been encompassed with Amaranthaceae. |

definition | Distribution: The Arecaceae family consists of c.190 genera and c.2365 species that
are primarily distributed in moist equatorial, tropical and subtropical regions. However,
there are some outlier species found in semi-arid and temperate regions. In Australia,
this family consists of 19 genera (6 being endemic, 11 being non-endemic and 2 naturalised
exotics) and 57 species (43 being endemic, 11 being non-endemic and 3 are naturalised
exotics). Description: This family are a group of perennial flowering plants that consist of climbers, shrubs, tree-like and stemless plants. For more details regarding the description of species within this family please see: https://profiles.ala.org.au/opus/foa/profile/Arecaceae Pollen Morphology: The pollen produced by the species in this family have a football-like shape with slightly rounded ends in equatorial view and rounded with an indent in polar view. The size of this pollen is variable depending on the taxon, but can be between 20-50um long (equatorial axis) and 10-20um wide (polar axis). On the length of the pollen grain there is a single long slit (monocolpate/monosulcate). The surface of most of these pollen has a mesh-like surface texture (reticulate), however, some can occasionally be spikey (echinate). |

definition | Distribution: Asteraceae is the family of flowering plants, with an estimated 1600+
genera and 24,000 species (plus many more apomictic microspecies) found worldwide
(except Antarctica), and growing in most habitats. In Australia about 300 genera and
1417 species, the native taxa mainly in subfamilies Asteroideae (Tribes Astereae and
Gnaphalieae). Asteraceae is the second most speciose family in Australia, exceeded
only by the Myrtaceae (c. 89 genera and c. 1858 species) and rivalled only by the
pea-flowered legumes (c. 140/1402) and Poaceae (c. 230/1300) Description: This family are a group of annual or perennial herbs, subshrubs, shrubs or rarely small trees or lianes, usually terrestrial, rarely facultatively aquatic. For more details regarding the description of species within this family please see: https://profiles.ala.org.au/opus/foa/profile/Asteraceae Pollen Morphology: The shape of the pollen in this family is highly variable and can be separated into two grain types. Type 1 grains are circular to clover shaped and often appear as a spikey ball. These pollen grains also have three pores and furrows (tricolporate), however they may be difficult to see. Type 2 grains have flat panels in a snow-flake like shape and have window-like apertures. The surface of these pollens are also spikey. The size of the pollen in both groups are variable with most taxa being 20-25um in diameter but some are seen to be smaller (15um). |

definition | Distribution: A genus of 30 species in temperate regions of the northern hemisphere
and the Andes in South America; the Flora of Australia publication listed one species
naturalised in Australia, the Australian Plant Census lists two species. Description: This genus is a group of trees or shrubs. For more details regarding the description of species within this genus please see: https://profiles.ala.org.au/opus/foa/profile/Alnus Pollen Morphology: The pollen grains from this family are pentagonal or quadrangular in polar view or elliptical when viewed from the side. The size of these are between 20-23um on the polar axis and 24-26um on the equatorial axis. These grains have 4-5 pores that protrude around the grain and are surrounded by annular thickenings that have a distinct semi-circular aspis underneath. The surface texture of these grains are faintly grainy (scabrate) and they have a finely granulate plasma. |

definition | Distribution: A genus of about 60 species from the Northern Hemisphere; 1 or 2 species
sparingly established in Victoria. Description: This genus is a group of deciduous trees or shrubs. They are monoecious and have bark that is dark brown to chalky white and is smooth. For more details regarding the description of species within this genus please see: https://vicflora.rbg.vic.gov.au/flora/taxon/9654af5f-bccf-4415-8736-efd0e12d1567 Pollen Morphology: The pollen grains from this genus have a circular shape in polar view and an elliptical shape in equatorial view. These pollen grains are between 18-25um in size and have 3 pores that are evenly spaced around the equator. These pores protrude slightly from the grain and have thick circular rings around each pore. The surface of the pollen grain is smooth, however the interior (plasma) is finely granular. |
