Trying to improve Acacia information

[nen888]

..
ps. acacia info heads, a recent post elsewhere got me looking at Acacias of Madagasgar ..it's actually quite a rich (though some cases very endangered) uncharted territory, with a few interesting sort of afro-asian species and around 6-7 endemics..
pictured are, for botanical interest:
i) Acacia rovumae found coastal regions of southern Somalia, Kenya and Tanzania, southern and western Madagascar.
ii) Acacia bellula (type specimen) endemic to Madagascan woodland.
and a real gem iii) A. sakalava, red flowered and known from only one location..seen here with butterfly ally (probably also highly endemic) ...

mrfi, please let us know how you go with Longifolia.
I personally am interested to hear, due to the number of Longifolia in my State, and my lack of success with numerous other Acacia so far heh.

That A. sakalava pic is lovely! What a great species name, too :thumb_up:

Re : Akarae et al , 2009 , [ previous page , p 62 .].. [ potential medicines for the treatment of liver diseases] . [ 1 ] Any info on these compounds ? . [ 2 ] The nature of these compounds . eg , alkaloids , flavinoids , terpenes , etc . ? .Acacias are in general regarded by most Aussies to be of little significance or commercial value . Nevertheless , it is becoming apparent that they are indeed an amazing species , of which we know very little , and in need of extensive research .

^..i'm finding a lot of 'preliminary' type phytochemical surveys of Acacias from the past decade, but with very few actually going the full GCMS ID of precisely what compounds..these papers are initially verifying the ancient knowledge of medicinal use of these acacias (nilotica, catechu, feruginea etc. ) ..more detailed analysis is probably going on in in-house confidential pharmaceutical company hidden labs..

Nexians,

Thanks for contributing such hard to come by info!

Years of experience has taut me to be conservative about such topics but from what i'v read it seems there are quite a few with the same hobbie.

Anyway i have had the same experience as most with my extractions of Mucronata, Longifolia and of course the mountain variate(not anymore) with varying results including success with all 3 and poor results with the first 2.

At this stage i am looking for a more viable option than the Phleb to work with that can have just as consistent results. I have just located a stand of Floribunda with long thin phyllodes
that will be the next to be tested. Bugger about the heavy rain atm as this weekend was looking like the time to get a small sample so will wait a few weeks, hopfully no more heavy rain. Also could anyone help ID this one that is just starting to bud, it has me puzzled? note the thick, rubbery red twigs that look like another i am fond of.

hey morgatron

not quite sure but that tree looks quite similar to acacia falcata or acacia pycnantha? pycnantha usually has broader and more tear shaped phyllodes though I've seen variations with slightly narrower phyllode

also one other question... do acacia floribunda's flowering patterns vary? Some of the floribunda that grow around town are going into flower again.. they flowered last spring too so only a few months back really. seems odd that they'd be blooming again. I'll take some photos and chuck them up tomorrow... its also possible they are another species, but they look very similar to floribunda .. especially when in flower. Some of the trees are not blooming yet

also, just planted some floribunda seeds and some mimosa hostilis seeds.. next will try and plant acuminata and victoriae but want to make sure the potting mix is ok. sterilizing some native potting mix at the moment and going to add a small amount of lime to make it more alkaline as i read the narrow leaf acuminata better suits to alkaline soils.. any ideas nen? hope they sprout!

hey brickie

might be and flowering early too??????
i will check my stand of Flori's and get back to you about the budding/flowering. after you mentioned it i have had a look at my mucronata's, i have 2 huge ones, and they have not come on yet but i have noticed a lot with ball flowers on racemes have come on early. my thoughts are that like Australian fauna they can become fertile more often or when the conditions are right, like the heap of rain the last year or two.

i will wait a few weeks of dry weather and got try my flori's. fingures crossedXXX

hehe.. who might you be that knows my old name? show yourself!

and yeah i did wonder whether maybe it has something to do with the intense rain of late... a similar thing seems to be happening with baileyana too.. unless the rods stay for a long time after it loses its flowers

 

[morgatrom]

Just wanted you guys to know that i read the whole thread, over a week, before i contributed thats why i used ya old name bro. bit wanky i suppose.:?

There is a huge stand of Longifolia about 20km from where i am, it grows like a weed almost, that i will check on the weekend for early flowering as well. This could throw a second spanner as with rain and flowering nothing would be worth investigating for a while. bummer

 

[acacian]

I would just call that dedicated ... thats a lot of reading! a feat .... ... hmmm... did you say the longifolia were in flower? they shouldn't be... it is meant to flower much later from june to october.. I know obtusifolia is a late bloomer around nov-december, though I doubt it would still be in flower. have you got photos?

 

[morgatrom]

Not sure about the Longifolia i will check it out on the weekend.

There is another that has caused me interest over the years Acacia Verticallata or Prickly Moses which with Longifolia is out of control in parts of the Otways. Maybe one day i will find the time to test this one as well

 

[morgatrom]

Oh yeah, could you please post a link to your Acacia Gallery mate. Buggered if i can find it cheers:thumb_up:

 

[nen888]

..hey there..yeah morgatron..waiting till the rains over's a good idea..and great reading feat..! good to see you back acacian..

i'm going to sum up some of the key findings of this thread soon..
new information on both useful species and ancient traditions surfaced, none of which has appeared collected in print before..this thread achieved a lot since June 2011..! be well all threaders..

and remember the Acacia Identification Thread..

 

[acacian]

good to be back well.. i wasn't really gone but I havent been doing much acacia experimentation and didn't really have much to contribute as far as research. about to go for a walk to pick some acacia baileyana phyllodes as well as some phalaris aquatica though. so soon enough I'll have results..

oh, and been tryina get ahold of ya past few days.. give us a buzz sometime. i head back in about a week .. will be back probably april..for good

.. Acacia photo gallery - The Ethnobotanical Garden - Welcome to the DMT-Nexus theres a link morgatron

Hey Guys

Just an update on the early flowering season theory, this year my largest of 2 Mucronata's is starting to grow spikes, with tiny buds on them, right up the top of the "tree". I can confirm that i checked my notes from last few years and this has never started before April since i have owned the property, 5 years. Also they were not there 3 days ago or were to small to see from ground level.

If anybody wishes to correct me on the id feel free. My best guess is that its a Mucronata/Floribunda Hybrid that's about 75/25% respectively. I will attach some photo's of them both in full bloom as you can hardly see a phyllode there are that may flowers. In the mean time check this out for a well loved specimen.

 

[acacian]

nice tree morgatron... just wondering what texture are the phyllodes? are they fairly papery or more stiff?

 

[morgatrom]

Thanks mate:thumb_up: there stiff so thinks its mostly Mucuro, flowers like hell but?

Some IMPORTANT news, the photos below are of a AlpiniaXPhleblo that my mate photoed at Buffalo on the way home from help clean up after the fires . Their all starting to flower up there too, all of them???????

The bottom photo is blurry but is a big Longifolia growing surrounded by Phleblo which will be a handy X for growing down my way:lol: its starting to flower too:roll:

 

[morgatrom]

oops here are the photos from my mate

 

[acacian]

morgatron... the first photo looks like it could be acacia obliquinerva rather than an alpina/phleb cross... they grow everywhere around mt buffalo too..
