Comment

Eremophila denticulata subsp. trisulcata is known only from the Eyre Botanical District in the areas north and north-west of Mt Ragged. The common name comes from the large yellow fruit which were thought to resemble cumquat citrus fruits. This species flowers over a long period and attracts honeyeaters to the nectar in the flowers.

Nice work with the new Rayfact, Dave.

This is a very graceful Eremophila.

These nicely show that the lens really is par-focal as I focused (at max aperture) in visible light, locked everything off, stopped down, shot visible, changed the filter, shot UV without ever peeping at the UV Live view image. We had some rain and although it was out of season (being autumn now not spring when they normally flower) several responded well.
