Dear Mr Holtturn. 
After some weeks furlough spent in the mountains of E.Java I 
got the material of G*Tahan collected by Corner* The sheets are label¬ 
led but not yet numbered* I. have gone through them and was able to 
give some additional identifications but X am not able to name Gesne- 
riaceae. Rhododendron, Vaccinium etc* with the aid of Ridley’s flora. 
Though Gentians and other temperate genera, which are so numer¬ 
ous in the Gajolands, Atjeh, are absent in this collection, the gen¬ 
eral impression is more or less the same* One could define it as an 
extremely depauperate Losir flora* The close connection is shown e*g* 
by Xyris grandis now also known from W.Sumatra, Oreobolus also found 
in Atjeh, Isachne pangerangensis s.l* in the same forms as from Atjeh, 
etc* Has Corner had any spefial intentions with the collection? I am 
sure that Dr•G.Kukenthal, Untere Klinge 9, Coburg, Germany, should 
be anxious to see the CIndium 1 s Corner collected* Has Eukenthal asked 
on loan material of Rhynchospora, Cladium, Schoenus, iotinoschoenus, 
Lepidosperma, Oreobolus, Carex & Gahnia from Singapore? He has worked 
up our material for his mpnographical ,, Pflans5enroich ,f -work* He is 
very able and returns material very rapidly* I know no other Cyper- 
ologist at the time of his knowledge and as Kukenthal is already very 
old though going strong it would be highly advisable to have the 
Singapore material named by him before it is too late* As he is a 
private person (pensioned Reverend) we pay the shipping charge vice 
versa* I am sure that he will be very glad to revise the Singapore 
material, which is for him rather easy work with his knowledge* If
