After a nice, dry, warm sleep we awake to another beautiful spring morning. Leaving Northam we head south down Spencers Brook Road to near Mokine, where we turn into Mokine Road. Next we turn at Leaver Road and find Mokine Nature Reserve, our first stop for the day. The first orchid found for the day is the Green spider orchid or Fringed mantis orchid (Caladenia falcata) which is the most widespread of the falcata complex orchids. The prominently clubbed lateral sepals emit pheromone-like odours to attract male thynnine wasps who pollinate the flowers.
Well the next orchid is the bright yellow Common donkey orchid (Diuris corymbosa) which flowers from August to October and is distributed between Gingin and Bunbury, then inland to Brookton. Donkey orchids are also called Pansy orchids by some, and the shape of the flower matches both common names to a tee.
Next up is the ever faithful Cowslip orchid (Caladenia flava) which is arguably the most widespread species of terrestrial orchid in Western Australia. The location we find ourselves in, leads me to believe the orchids growing here are the subspecies “flava”, which is also the most widespread of the 4 named subspecies. These orchids can be found in their hundreds, however we only find scattered individuals and clumps.
Next up we find some Dark banded greenhoods (Pterostylis sanguinea) in both their green and brown forms. These orchids are nearing the end of their season as they are noted as flowering from June to September.
Another related orchid is also located. The distinctive Jug orchid (Pterostylis recurva) which is found from Geraldton to Israelite Bay, is another orchid that is regularly found on our treks. This orchid ranges in colour during it’s lifecycle from green to light brown, with the 3 pictured showing this feature.
Then another bright colour catches our eye. A dual-flowered Little pink fairy (Caladenia reptans subsp. reptans) is found growing on the road verge. The purple underside to the leaf is a feature to help distinguish it from the other pink fairies.
Further into the reserve I go to try and find anything else and as luck has it I come across a lone Dancing spider orchid (Caladenia discoidea), standing tall in the open. In fact they can be up to 450mm in height, however this specimen was around 270mm in height. The short, horizontal petals and lateral sepals are a distinctive feature of this small orchid. And just to record the sighting we did also find a still recognisable Hare orchid (Leporella fimbriata), which flower March to June.
What a great little spot this turned out to be. We have spent just over 1hr here and have found 8 orchid species. Next time we will need to explore further into the reserve as we were only a few metres in from the road this time. As it is now after 11am we make tracks for our next exploration site.
