§ 7. Plantae Junghuhnianae ineditae. I. Notes on some Javanese species 

 of an as yet unpublished collection of Junghuhn's plants, in 's Rijks Her- 

 barium at Leiden. 



A few months ago, while searching in 's Rijks Herbarium at 

 Leiden for some herbariumspecimens of Junghuhn's Javanese alpine 

 plants, which were required by me, one of the officials of that 

 institution found among the separately preserved collections of 

 " Indeterminata" a fairly extensive collection made by Junghuhn. 

 This collection had already undergone preliminary determination 

 by me, in 1896 (during a short stay at Leiden), at the request of 

 Dr. J. Valckenier Suringar, but for the rest remained wholly un- 

 determined. 



As I noticed in this collection a number of Javanese alpine plants, 

 and as it seemed worth while to study the collection as a whole, 

 I resolved to complete the determination, begun in 1896, and to 

 publish the results. The latter, as far as an enumeration of the 

 Javanese specimens is concerned, are ready for the press, but 

 will be published separately ; here I only append a few remarks 

 on this collection of Junghuhn. 



The whole collection consisted of fifteen large packets and fully 

 560 collecting numbers. 



As is the case of very many old herbariumcollections, the labelling 

 of a large number of these specimens left much to be desired. On 

 the other hand some specimens were provided with detailed col- 

 lecting labels, written by Junghuhn himself. With a few exceptions, 

 all the specimens were quite undetermined (without determination 

 of the genus and order). Most of the specimens were also without a 

 collecting number on the label. In consultation with Dr. J. C. Goethart, 

 Keeper of 's Rijks Herbarium, it was accordingly decided to give 

 running numbers to this whole collection of "Plantae Junghuhnianae 

 ineditae", these numbers being independent of the old numbers, 

 extant in some cases, but not explained by any list or publication. 

 Printed labels have also been added, running partly as follows : 

 "Plantae Junghuhnianae ineditae. In insula Java legit Dr. Fr. Junghuhn 

 anno 1838 — 1863 sub n..." Except for the substitution of the word 

 "Sumatra" for "Java", the specimens from Sumatra in this collection 

 have received a similar label.
