Dear Professor Svedelius, 
In your letter of ^rd April answering my questions 
about Radem&chia and sitodium, you very kindly offered to 
give any further assistance which might be needed. I now 
find myself obliged to call upon your kindness for the 
finishing touches to my notes on Artocarpus. 
At the same time as I wrote to you, on ^th January, 
I wrote also to the Botanical Department of the British 
Museum in order to obtain extracts of a few old papers 
and books to which we have not access in Singapore. 
Mr.Ramsbottom acknowledged my letter, since when I have 
heard nothing further. I also dislike referring matters 
to taxonomy to Kew Herbarium oecause our letters are 
passed to Dr.Sprague from whom we receive no reply. 
We have cleared up the protolea of the Jack-fruit 
and Chempedak. The Chempedak, as you say, must be called 
A.Integra (Thunb.) and I now decide that the Jack-fruit 
must be called A.heterophylla Lam. This is annoying, but 
such are the Rules of Nomenclature. There are two earlier 
names for the Jack-fruit, namely Sitodium cauliflorum 
\ ? 
Gaertner (De Fruct.I, 1786, p. 5 ^ 5 ) and A. jaca lam. (Sngy'cl. 
- ----u. . ' y: .-.. ... v V \ 
III, 1783 , p•2). Both these names' must be discarded^ 
however, as superfluous names at their date of publication 
because they included the type of A.integrifolia Iinn.f. 
in their synonymy (see Intern.Rules Bot.Nomencl.Art .69 “ 
Radiola,
