Plants of Chillagoe – a provisional checklist

BrachychitonI had the very great pleasure of visiting Chillagoe a number of times between 2012-2017 and have compiled a very provisional checklist of the plants I could identify. The most characteristic feature of that area must have been the presence of Currajongs (Brachychiton spp.), particularly near and on the limestone outcrops where the caves are. These short but majestic trees were often associated with an interesting monsoon vine thicket which consisted of quite a variety of grape vines (Vitaceae) and a number of interesting shrub species such as Croton arnhemicus, Graptophyllum excelsum and Dendrolobium arbuscula. Among the limetone rocks I was fortunate to espy a magnificent display of Cardwell Lilies (Proiphys amboinensis) and also some interesting fern species including Adiantum and possibly a poikilohydric species I haven’t determined. The woodlands around the area was characterized by ironbarks (possibly Eucalyptus crebra) and ghost gums (Corymbia dallachiana and Corymbia confertiflora) and also had a number of very characteristic savanna trees and shrubs such as Erythrina vespertilo, Terminalia platyptera and Atalaya. More on Chillagoe Plants when I update my Flickr with my macro pics.

About David Tng

I am David Tng, a hedonistic botanizer who pursues plants with a fervour. I chase the opportunity to delve into various aspects of the study of plants. I have spent untold hours staring at mosses and allied plants, taking picture of pollen, culturing orchids in clean cabinets, counting tree rings, monitoring plant flowering times, etc. I am currently engrossed in the study of plant ecology (a grand excuse to see 'anything I can). Sometimes I think of myself as a shadow taxonomist, a sentimental ecologist, and a spiritual environmentalist - but at the very root of it all, a "plant whisperer"!
