Summary

Terminology for asexual gemmae of Lunularia vulgaris and comparison with Marchantia.

Summary

would like some cotton seeds.

Summary

Summary

Suspects WTT-D is the author of a good review of Erasmus Darwin in Nature [21 (1880): 245–7].

Summary

Asa Gray wants seeds of a variety of cotton known as vine cotton.

Summary

Wants Ipomoea seeds for observing germination.

Summary

WTT-D’s suggestion about absorbent function of pegs in Abronia suggests origin of pegs in Welwitschia, which deeply interests CD. Previously could not see how pegs became large enough to be of mechanical use. Now thinks tissue between hypocotyl and radicle absorbs fluid, which would favour rise of peg to expose larger surface.

Rejects German contempt for investigating use of organs.

Asks WTT-D to observe how worms draw Robinia leaves into burrows.

Summary

CD may not mean same thing as WTT-D by absorbent pegs in Abronia.

F. O. Bower’s paper on Welwitschia [germination] [Q. J. Microsc. Sci. 21 (1881): 15–30] will appear in January.

Has observed earthworms for CD: they do not draw Robinia leaves into burrows by the petioles.

Summary

Wants plants with two sets of anthers of different colours. Fritz Müller letter [13041a] has made him wish to renew experiments and observations carried out 20 years ago.

Summary

Wants Monochaetum flowers for examination as he has forgotten the structure and cannot publish until he has repeated his observations and experiments.

Summary

Thanks for Monochaetum flowers; his old notes have now become intelligible.
