Summary

Discusses specimens of Utricularia.

Mentions JR’s work on desmids [The British Desmidieae [Desmidiae!?] (1848)].

Summary

Thanks for the Pinguicula plants, which have recovered, and asks if he could also send Utricularia, since his other supplies have failed.

Summary

Sends specimens of Pinguicula and observations made on them. [See Insectivorous plants, pp. 390–1.]

Summary

Wants particularly to know whether seeds or leaves of other plants are ever found adhering to the leaves of Pinguicula. Observations would perhaps best be made in a month or two.

Summary

Thanks for Drosophyllum. No longer needs Utricularia.

Summary

Thanks JDH for extract on Hedychium pollination; it shows CD’s prior interpretation was incorrect.

Summary

Did not know cabbage contained so much nitrogen.

Pinguicula more excited by seeds than Drosera. Asks for information about Pinguicula.

Asks name of weed.

Asks to borrow Utricularia plant.

Summary

Asks about insects and seeds on leaves of Pinguicula.

Summary

It would be interesting to prove that some plants feed on decayed animal matter whilst others like Drosera can digest fresh animal matter. Suggests the method for observing this.

Summary

Thanks for letter and seeds.

Asks that Hooker return references about plants eating insects.

Discusses Pinguicula.

Summary

Asks what proportion of leaves of Pinguicula have insects adhering to them. Also, whether seeds of any plants ever adhere to the leaves, and in what situations does P. vulgaris grow.

Summary

Reports on his examination of the dried specimens of Pinguicula at Kew to answer CD’s query whether all species secrete.

Summary

Has some Utricularia minor for CD. Has found the bladders on U. vulgaris are not floats.

Thanks CD for book [Descent, 2d ed.].

Summary

Observations on the insects captured by Utricularia.
