To Adolf Ernst   11 September 1880

Summary

Thanks for seeds of Cobaea;

was much interested in AE’s article ["On the fertilisation of Cobaea penduliflora", Nature 22 (1880): 148–9] opposing G. E. M. Bonnier’s view ["Les nectaires", Ann. Sci. Nat. (Bot.) 6th ser. 8 (1879): 6–212].

Case of Lisianthus is an excellent one of structure and movement of parts adapted to cross-fertilisation.

Asks whether worm-castings are found in the area.

Edmond Perrier of Paris would be pleased to receive earthworms collected in Venezuela.
