Hey pitdog,
The secret to using the female flower head of the Cattail (Typha spp.) is to have some very fine, wispy pieces of Birch (Betula papyrifera) bark in the Cattail. It has to be fine and wispy otherwise it takes too long to get it going.
This also is a good idea, to a certain extent with Cedar (Thuja occidentalis) as it goes out fairly quickly (not near as fast as Cattail, though), at least it does with our Eastern White Cedar, but it can be blown back into flame.
Very true, but don't breathe in the fumes. Apparently some nasty little bugs can be found in old bird's nests.
And as far as Pine (Pinus spp.) needles go, (Normark quote

"Then blow like a Mother...." Absolutely true.

Also: "almost any dried grass can be used as tinder". I found that while very dry, fine grass works very well, the coarser stuff can be a 'no-show', at least for me.
BTW, since we're mentioning Cattail, it can also be used as a slow match. A six inch flower head will smoulder for about 2 hours in still air. Also functions as an insect smudge. Or, if you can't get the fire going, open up some flower heads and jam the material down between layers of clothes. Makes an excellent insulation.
