Asks for specimen of Orchis pyramidalis for his work on insect fertilisation of orchids.
Thanks GB for specimen [of Orchis pyramidalis].
Discusses a great difficulty with orchids: "Insects visit several species which never secrete an atom of honey." [See Orchids, p. 44ff.] Does GB know whether nectar is ever secreted and reabsorbed promptly?
Thanks GB for arranging for his paper ["Two forms of Primula", Collected papers 2: 45–63] and for his photograph.
Requests more precise details about Oxalis, to which GB referred in his remarks on Primula.
Would prefer to have Primula paper published in the Linnean Society’s Journal rather than Transactions.
Thanks GB for valuable letter [3331].
Will follow his suggestion about violets.
Discusses differences between Thymus and Primula.
