germination of South African Romulea?

In my limited experience to date with wild collected seed of unknown age,
germination of autumn sown seed is typically erratic and the total germination
percentage very low, typically <5%.  Is this typically other peoples
experience, or is germination higher with fresh seed?  Has anyone tried
scarification or hot water treatment to abrade/soften the hard seed coat prior
to sowing with any success? I assume that antelope/sheep browse Romulea
capsules, and passage through their guts might achieve similar effects in their
habitat?    The scientific literature suggests that smoke/fire does not
directly imporve germination of Romulea. 

Any experiences?
