Soliva sessilis, one of up to nine species of the genus Soliva, is a low-growing herbaceous annual plant. Its common names include field burrweed, Onehunga-weed, lawn burrweed, lawnweed, and common soliva. It is one of several plants known as bindi weed, bindii, or bindi-eye. A weedy plant known for its tiny sharp-needled seeds. It appears with small feathery leaves reminiscent of parsley, with an exposed upward-pointing rosette of seeds in a pod nestled at the branch junctions. Eventually small flowers appear if the plant is allowed to develop. Those familiar with the plant may also know it as "bindi patches", which can't be walked on barefoot. Dogs and cats are no less affected and tend to avoid areas where they have encountered it. Originally native to South America, the plant is now well established in many places around the world, including Australia, New Zealand, southwest France, Hawaii, California, and several other states in the United States. It is mainly found in parks and ovals, though it has also become an invasive species in lawns in the southeast USA, Australia and New Zealand. Bindi weed can be manually removed by pulling it out at the root, usually when it's grown big, and started to flower, and before seeding—especially after rain when the ground is softer. A hand tool that pinches the tap root and enables some leverage while getting in under the central core is the best method. Bindi can be treated with herbicide. Late winter and early spring are the best times to destroy the weed before its seeds germinate. Effective herbicides are typically combinations of MCPA and Dicamba, which target broad-leaved plants but not grasses. These chemicals have similar effects as natural plant auxins, and their increased concentrations cause unnatural plant growth which kill the plant. Mowing grass to a higher level will allow more competitive plants to thrive in the area. Bindi weed also favours compacted ground, so aerating the soil should also reduce the presence of the plant

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Soliva sessilis has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Soliva sessilis carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Soliva sessilis was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.
Signal

How strong is each trace?
Modelled climatemodelled
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
