CD came to believe Drosera drew its nourishment from insects because it grows where no other plants survive. Doubts glands are modified stomata.
Suggests works by Grönland and Trécul.

My chief reason for believing that Drosera drew the greater part of itsnourishment from captured insects was its growing where no other plantscould grow. I began experiments on the comparative growth of plantswith and without insects, but failed by the plants being accidentallypoisoned. It seems to me likely that the chief difference would be inthe production of seeds. I did not observe the developement of the glandsas this had been partly done by MM. Grönland & Trécul; butMr Bennett has recently read a paper on these glands which is publishedin the Monthly Microscop. Journal Jan 1876. I can hardly believe thatthey are modified stomata.
I am glad my book has interest you.
