Acacias of Spring

15 August 2010

Despite there being a small gale blowing at lunchtime I took myself and the small dog off to see what members of the genus Acacia I could find flowering.  I managed to find 4 on this day: I couldn't find any A. genistifolia although I have seen it on the property, and the A. pravissima was not yet in flower.  I will try to keep this post updated as I find other species.

In the images which follow I have tried to include both the flower and leaf/phyllode, as the latter are far more reliable than the former as a guide to identification.

Acacia buxifolia: 'Box-leaf Wattle'.  On our property this is only represented in the direct seeding by Greening Australia.

Acacia Dawsonii:  Poverty Wattle.  So called because of the sparseness of the flowerheads.  This is a 'foreigner' which has escaped from someone's planting and now grows a fair bit in the area.
Acacia dealbata:  Silver Wattle.  The commonest tree on the block with many dead clumps in the top paddock surrounded by saplings growing up from the old suckers.
Acacia gunnii: Ploughshare wattle.  So called because of the shape of the leaves.  Along with A. genistifolia, one of the very early flowering wattles.

I was able to track down some A. genistifolia albeit some kilometres away, between Hoskinstown and Forbes Creek.  The following image shows why the name translates as "Gorse-leaved Wattle".
The Acacia pravissima (Ovens Wattle) which lines our garden has hit it's stride on 8 Ovtober.

A tour of the West (part 1)

Image
A friend from my time in the UN sent me some photos of her family trip along Route 66.  They did this is a large camperwagon rather than a Chevy Corvette (apparently the kids jacked up about being offered a trip in the trunk).  It seems to have been a very good trip for them and most interesting to see their photos.  It was also educational for me, as I found out the German for rocking chair (schaukelstuhl, since you ask). They did 7200 miles in 30 days - a pretty serious bit of distance. This made me think of the trips we did in 1981 when living in Denver.  Frances initiated that idea by getting a book about the National Parks of the West  and marking interesting places.  I then worked out a route on a Rand-McNally Road Atlas (GPS was unknown then  - as were iPhones, personal computers and the internet).  From memory, taking nearly the whole Summer school holidays we covered about 10,000 miles in 70 days.  Here, approximately,  are our routes: That map comes from Google Maps (G

Insects from pine trees

Image
This afternoon (13/1/2015) we were looking out of our sunroom and noticed a strange bit of mist.  On getting my binoculars on the case I found it to be a cloud of tens of thousand of insects.  They appeared with naked eye to be flying away, but with binoculars I thought they were circling. Here are some images In the second one it may be possible to see there are two streams coming from the top of each tree. There was a loud buzzing noise but that could just be several thousand wings. Earlier in the day Frances had been to some nearby willows and they were infested with many little black soft bodied insects.  Perhaps they shifted to the pines and were swarming? Help!! Any information welcome. A colleague, from Wamboin, had noticed a similat phenomenon, but involvng eucalypts rather than pines!  Here are the photos he took with his phone. I have consulted some expert friends.   Their responses were: I would have gone for chironomids. I recall years ago driving al

Satin Bowerbird gets ready for Lanigans Ball.

Image
Having some time to spare today I went to check the bower near "Tom Green's Seat" in the Australian National Botanic Gardens.  The bower was well occupied by what I take to be - based on the green plumage and yellow bill - a 5th or 6th year male Satin Bowerbird.  (With all these images, click on them for a bigger - unfortunately not better focused picture.  The shots were taken hand held on full zoom from about 10m distance into a fairly well shaded location.) He was very much engaged in adding to the construction. Then it seemed that another bird called from the bush above.  This led to a whole lot of activity: the most spectacular (and worst imaged) was a flash of the wings: The bird also did a fair bit of hopping around.  Given that it was still immature I called to mind the greatest traditional Irish song of all time: Diarmuid O'Leary and the Bards performing Lanigan's Ball .  This ditty refers to spending "6 long months at Brooks Academy learning
