JDH writes to Sir William Turner Thiselton-Dyer regarding arrangements for publishing Harriet Thiselton-Dyer's drawings [in CURTIS' BOTANICAL MAGAZINE]. JDH criticizes the publisher Dulau for giving WTTD trouble with A HAND-BOOK TO THE FLORA OF CEYLON. JDH discusses his difficulties with classifying the grasses of Ceylon [Sri Lanka], [Otto] Stapf assists him with this but they disagree on the division of tribes & Stapf's key from FLORA CAPENSIS is proving flawed. JDH is going to Dartmouth, whilst he is away [William Botting] Hemsley will look after the BOTANICAL MAGAZINE.
