Blue Mountains with the Botanists

We had a very restful night at our Blue Mountain hide-away, The Waldorf.  After two days of being on the road by 7:30 it was luxurious to leave at 8am after a hot breakfast. 

Our first stop was a little walk through temperate rainforest near Mt. Wlison.  This was a short walk, but there were three interesting plants for me. (I think more for everyone else.).  Because of a recent wind storm, we saw some branches that had blown down from the canopy above, fairly recently.  They are doomed, now, unfortunately, but we could get a good look at how the orchids live on the branches of the host tree way up high where they also receive much more light than on the floor.  The next interesting  plant is called Tasmania , and it has crazy fruit that are very "primitivve" (ancestral is the correct term) where the style ends up outside of the fruit as it develops.  Finally, we saw a little fern called Tmesipteris.  It would be hard to find without someone pointing it out.  When I was in college, this little fern was thought not to be a fern, but something ancestral to all the vascular plants.  This little fern is very simple-- no true roots or leaves.  Since its DNA has been sequenced, it's true relationship to other ferns has been determined.  They are pictured above, and what you see are highly specialized stems serving as the photosynthetic surface AND as the root surface.  Through their evolution, they have lost their roots and leaves.  (Don't let this shake you, just think of snakes that are reptiles that have lost their limbs through evolutionary time).  They are growing on a tree fern stem.  This may not excite you, but look at just part of the crowd it drew.  I haven't drawn a crowd with that many cameras since I was halfway through my single digit birthdays!

Our next stop was further into the mountains.  To get there, we took a road with a name that begs explanation.  The name of the road is "Bells Line Of Road."  It looks like a mistake on the road sign, but it is a very deliberate name.  Bell was a surveyor who laid the road line, although the road was not built right away, for political reasons.  Folks were well aware of his road line, though, probably because it was so superior to the road that was in use, so when the road was eventually built, it was named Bells Line Of Road. 

At this stop we climbed part of the way up Mt Banks.  At least, the map names it as Mt Banks.  At the trailhead, the historic marker says "Mt Banks or Mt King George."  I am sticking with the Mt Banks name, in part because I am pretty sure this George was the one America fought a war against, and also because it was named Banks, after a famous botanist, by the explorer who climbed the mountain.  We had beautiful views from the near top.

And a close look at some tiny plants.

We drove to our lunch and afternoon spot after our descent.  This was the lovely Mount Tomah Botanic Gardens, part of the Royal Botanic Gardens in Sydney.  Since Mount Tomah is in the Blue Mountains, it can host the cold climate collection of the Royal Botanic Gardens.  It is a new garden--really only about thirty years old, although you would never know that by walking amongst the beds.  It has a nice geographic arrangement as well, with a creek separating plants of the northern hemisphere from the southern.  We got to see Wollemi Pine, nearer to its wild home, in this gardern.  (There is a specimen growing in the Royal Botanic Garden in Sydney.)  The Wollemi was thought to be extinct, but then found by some bushwalkers in the Blue Mountains about ten years ago.  Although there is a small cluster in the wild, its location a closely guarded secret.  Public, private and botanical gardens are its refuge.  It is a cool looking tree.  And, it has its own Facebook fan page.

Male cone.  The Wollemi has very soft needles.

The parking lot of the Mt. Tomah Botanic Gardens was our good-bye location, since some members of the trip didn't come directly back to Sydney.  We had a pretty quiet van ride back; I think passengers of all ages were thoughful and a bit tired.  Murray Henwood (University of Sydney) and Barry Ponns (Royal Botanic Garden) did an excellent job planning this trip, and especially exercising patience and high, good humor with the trip participants.  Believe me, telling a group of botanists that they have to ceasing looking at and photographing plants in order to get to the next stop, is quite a challenge.

We have a city day tomorrow.
