Yes, found what my distant memory recalled. I think the author was talking it up a bit, but it possible:
"Suggestions have been made that the Dictamnus albus plant, found throughout northern Africa is a candidate for the burning bush. In the summer, the plant, also known as the “gas plant,” exudes a variety of volatile oils that can catch fire readily and may give the impression that the bush is burning. So was Moses witnessing the combustion of a mix of terpenes, flavonoids, coumarins and phenylpropanoids? An interesting hypothesis about the burning bush, but one that can be readily doused.
The plant’s volatile oils do not catch fire spontaneously, they need a source of ignition. Moses is unlikely to have been walking around with flintstones looking for bushes to ignite. And when the vapours coming off the Dictamnus albus plant do ignite, the flash lasts just a few seconds."
Which would approximate to using a flintlock and a plant that I think was also called wildfire. I see no reason why Moses would not have the means and knowledge to make fire. A long, long, while ago I came across something about african natives using a plant called or referred to as "wildfire" to make fires.
