Diario del proyecto Shrubby samphires and climate change

Ever put a photo of a samphire up on iNat, to have it languish unidentified for months? It is a problem that is common in plant groups that don't have flashy flowers, or where many species look very similar. So how to increase your chances of a successful identification? The tips below should help. They look at photographing an important samphire, Tecticornia arbuscula, the shrubby samphire for the current project looking at the health of this species in Southern Australia.

First up, a photo of the entire bush in its habitat tells potential identifiers a lot - is it a low prostrate plant or an upright shrub? Near the sea? Inland? The shrubby samphire in this photo is clearly a large shrub. https://www.inaturalist.org/observations/43537254

In this photo you can see the woody structure of these long-lived plants: https://www.inaturalist.org/observations/44119604

And in this photo the shrubs are clearly growing in the intertidal zone - they are at least double the height of the sea rush that grows with them:

Next we zoom in to look for flowering spikes. Flowers on samphires are greenish, and are arranged in groups around a spike. Each group is separated from the group above by a bract of fleshy material. All greenish! The flowers of Tecticornia arbuscula actually hide down behind the bracts BUT a closeup photo will often reveal the single female flower on each side of the flower spike. You can see the divided stigmas sticking out in this iNat record: https://www.inaturalist.org/observations/45466897

As the fruits mature, the flesh of the bract yellows and shrinks back a bit around the fruit, which is buried close to the stem. The woody female style which was topped with those delicate stigmas dries and hardens, and remains sticking out of the fruiting body, like little Pinocchio noses. https://www.inaturalist.org/observations/36479163

A set of pictures that includes these details is simple to identify, and will result in your contribution bring rapidly identified.

Added the Slender-billed Thornbill to the project because the southern variety, subspecies rosinae is usually found in Samphire scrublands, so a large percentage of the photos are likely to show Shrubby Samphire, Tecticornia arbuscula in the view.
