I am looking for the kind of tree/bush for the burning bush of Moses. What are the kinds mentioned by Rabbis? I read before that some Rabbis identified the tree with the Sidr Tree. I need to know where specifically Sidr Tree (or cedar) is mentioned too.
Most commentaries render this as some sort of thorny bush (see Rashi, Ibn Ezra).
In terms of identifying which exact species it may have been, a great resource is Rabbi Kaplan's Living Torah commentary to Exodus 3:2, which states:
S'neh in Hebrew. This is most probably the black raspberry (rubus sanctus), which has berries that turn red and then black (Yerushalmi, Ma'asroth 1:2, 3a; cf. Septuagint; Vulgate). The Midrash also identifies it as a species of thorn-bush (Sh'moth Rabbah 1:9, 2:9). Others identify it as the sana plant (Casia obovata), the shurbu (Colutea istria) [or] the wild juju (Zizyphus spina).
