In 1856 Miquel evidently resolved to bring out a second part 

 of the publication, which appeared in 1854 (Plantae Jungh. Enum. 

 pi.). This follows for instance from his quoting in the Flora Ind. 

 Bat, II (1856) p. 1053: "PI. Jungh. I. p. 84". My publication on 

 the PI. Jungh. ined. might therefore perhaps have been called "PI. 

 Jungh. II". Since, however the only part, which appeared in 1854, 

 was not specially designated as part N c . I, I have now, for the sake 

 of clearness, not called my present publication also "Plantae Jungh.", 

 but "Plantae Junghuhnianae ineditae". 



I found this latter designation for the first time in Miquel Fl. 

 Ind. Bat. I. 2. (1859) p. 356. An authentic herbariumspecimen of 

 Flueggea serrata Miq., collected by Junghuhn in the higher mountain 

 regions of Java, and found by me in the university Herbarium at 

 Utrecht, is published there for the first time and is quoted by Miquel 

 1. c. as PI. Jungh. inedit. 



The authentic herbarium-labels, preserved at Leiden, which refer to 

 the species treated of in the above-mentioned publication {PI. Junqh. 

 Enum. pi, 1854) bear numbers, which correspond with that publi- 

 cation of 1854 and are sometimes also quoted in the later publications 

 as PL Jungh. n. 1, 2, 3, etc. In order to avoid any possible con- 

 fusion with these numbers, I have quoted below the specimens in 

 the collection now described by me, as follows: PI. Jungh. ined. 

 n. 1, 2, etc. 



The number of exclusively alpine Javanese species met with in 

 the above collection, is not large. Nevertheless I found several more 

 or less characteristic Javanese alpine species represented, sometimes by 

 a profusion of specimens. As such the following may be mentioned 

 among others: Urtica grandidenta Miq., Thalicirum javanicum Bl., 

 Myrica javanica Bl., Euphorbia Rothiana Spreng., Viola serpens 

 Wall., Leptospermum javanicum Bl., Clethra canescens Reinw., 

 Leucopogort javanicus (Jungh.) de Vriese, Lysimachia ramosa Wall. 

 var. typica Knuth., Primula imperialis Jungh., Buddleia asiatica 

 Lour., Vaccinium Teijsmanni Miq., Vaccinium varingaefolium Miq., 

 Rhododendron retusum Benn., Lonicera oxylepis Miq., etc. 



With some specimens of the collection, now described by me 

 I found labels, on which, presumably about half a century a«-o 

 was written in the hand- writing of the late Professor W. H. de Vriese : 

 "legit Junghuhn, herb, de Vriese'. It seems therefore, that before 

 's Rijks Herbarium at Leiden acquired this collection of Junghuhn 

 whether by purchase or by donation, it belonged wholly or partly 

 to that herbarium.
