Bursaria Spinosa (a.k.a.: Native Blackthorn, a.k.a.: Christmas Bush)
(People actually plant these things in their gardens! ;-)
All along the Mighty Mitta... especially where you want to get out and scout or fish. The ends of the spines are very fragile and love to just come right off and bury themselves under your skin and then get sore and annoying. Kind of like the "jumping" Cholla cactus back in the Grand Canyon.
I thought the Woolly Gravillia was what was locally called "Christmas Bush", but no... this plant seems to keep its flowers through December, hence the name.
I used to send my Kokatat drysuits to their California shop for a hydrostatic test, patch and gasket repair when I was going back Stateside every year. They always used to ask; "What's up with you Aussie paddlers??!! Your drysuits always have a million tiny little holes!!" I tried to tell them about this little bush, not to mention the blackberries. Now I send my gear to PaddleSports & Bruce Baxter for repairs and replacements.
