Linnæus conceived them to originate from the pith, and the stamens from the wood, and hence constructed an ingenious hypothesis, relative to the propagation of vegetables, which is not destitute of observations and analogies to support it, but no countenanced by the anatomy and physiology of the parts alluded to.
