Asks whether glaucous plants in Venezuela are more common in drier areas.
Has read AE’s paper in Nature [21 (1880): 217] on Melochia, a new family of heterostyled plants, and suggests some crosses to be carried out to determine the fertility of illegitimate seedlings.
Thanks for interesting letter; is sure it would be worth while to test fertility of illegitimate offspring of heterostyled plants.
Would welcome any information on occurrence of bloom-covered leaves on dry plains.
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.
CD fears that he exaggerated the importance of worms in forming ledges on hillsides [see Earthworms, p. 278 ff.].
