I’m discovering that identifying wildflowers is very time-consuming. Our two field guides cover wildflowers from all over Australia, with multiple variations on most species. Looking at the small illustrations or photographs in the field guides, often nothing looks exactly the same as the wildflowers I have found. However, by looking at locations they are found, the shape of the leaves, descriptions of whether the stems are hairy or smooth, whether the plant is low growing or a large shrub give me clues. Often I can at least narrow it down to a family of plants, with one or two possible species.
Goodenia
Goodenias were widespread and long-flowering on our property. They seemed to be around for the end of Winter, and all of Spring. More than ten different species of Goodenia are described in our field guides, but none of these seem to match our Goodenias – so I need to do more research on this one. This prompts me to put a more location-specific field guide on my shopping list.
Tall Sundew
An insectivorous plant, the Tall Sundew grows in moist locations – which is probably why we only found them on lower ground in one corner of our property. The sandy loam soil generally does not hold water for long. When I took these photos, I had no idea what it was, and focussed my lens on the flowers, which are quite beautiful and delicate. Next time I see one, I will make sure to photograph the leaves, which are sticky with long hairs – designed to attract and trap insects.
Guinea Flower
Potentially a Rough Guinea Flower (Dilleniaceae Hibbertia aspera) this shrub grew among the bracken along the Southern side of our property. In October, my photography skills were not as good as they are now, so branches and leaves obscure some of the detail. However, it is possible to see the pale yellow colour of the flowers, and sufficient leaves to narrow down the species somewhat.
With six further flowers I am having difficulty identifying, there will be Part 3 to the October Flowers post in a few days time. Hopefully I can at least attach a broad category to each flower.
Fifteen Acres 
The Goodenia photographed is Goodenia lanata, Trailing Goodenia. It is the emblem of the Field Naturalists Club of Ballarat.
The Hibbertia is Hibbertia riparia, Upright Guinea-flower, which is common south of Ballarat. H. aspera is generally a coastal species.
Excellent! Thank you so much! I keep looking at photos of Goodenia and none of them look like the one we have, so this solves a long-held question. Do you know if there is a field guide specific to Central Victorian flowers and plants? The reason that Part 3 of October Wildflowers has not yet eventuated is that I can’t find a match for the flowers I’ve photographed. I may just put them up without names at this point, and add them as I can identify them.
