ON SOME NEW MALAYAN CORYLACEJE. 



By H. F. Hance, Ph.D., Member of the Royal Botanic Societies of 

 Eatisboii and Belgium, &c. 



In the summer of 1876, Dr. Scheffer was so kind as to send 

 me, from the rich herbarium of Buitenzorg, a number of specimens 

 of Malayan Coryhicea', almost all unnan^ed, but many very rare 

 and- valuable, wath full permission to describe such as I might 

 consider new. A.fter a patient examination and comparison of all 

 these, I selected the following as being undescribed ; and as a 

 testimony to the care I bestowed on their study, I may say that 

 Dr. Sche£fer, to whom I communicated my views, has signified his 

 assent, not only as to the species being new, but also in regard to 

 the systematic position I have assigned each, except in the case of 

 Quercus rhioensis, which, from my omission to indicate it by its 

 number, he did not identify. The species described all belong to 

 Miquel's * Sumatran province,' or Wallace's • In do -Malayan region' 

 of the Archipelago. 



1. Quercus (^Cyclobakmus, Eucydohalanus) Rajah, s/j. nov. — 

 Ramis angulatis tenuiter tomentellis demum glabratis, foliis 

 coriaceis ovalibus v. ovali-oblongis margine integerrimis basi in 

 petiolum 3-4 linealem cuneato-angustatis apice rotundatis subitoque 

 breviter lineari-rostratis supra glabris lucidulis subtus opacis 

 tomentoque squamoso-furfuraceo denso gilvo v. pallenti obtectis 

 costa satis crassa supra elevata costulis ad utrumque latus cu'citer 

 10 sub angulo 50° egressis utrinque paululum prominentibus intra 

 marginem obscure anastomosantibus 5-7 poll, longis 2^-3 poll, 

 latis, fructibus secus pedunculum validum folio parum breviorem 

 confertim sed singulatim dispositis sessihbus, cupulas patelliformis 

 7 lin. diametro extus glabratae intus centro pulvinatim elevatse 

 zonis concentricis 4 indistinctis integris, glandibus obovoideo- 

 hemisphaericis dilute brunneis basi excavata pallida tomento brevi 

 sericeo griseo plus minus persistenti tectis 9 hn. altis 10 lin. 

 diametro columna stylina apiculatis. 



Ex archipelago Malayano. (Herb. hort. Bogor., n. 11484.) 

 Nearest the Bangka Q. Miqiieliana, Scheff. ! in Dr. Scheffer's 

 oiDinion, in which I entu-ely concur. It is, however, perfectly well 

 distmguished by the shape and colour of the leaves, their stouter 

 costules, the sessile fruits, less numerous and distinct entu-e-edged 

 cup-scales, and by the much paler tomentose acoms. 



2. Quercus (Pasaiiia, Eupasania) RmoENSis, sp. nor. — Ramis 

 angulatis glabris lenticellatis, foliis coriaceis a basi cuneata elliptico- 

 oblongis breviter acuminatis integerrimis glaberrimis costulis 

 utrinque circ. 12 tenuibus angulo cu'C. 60^ egressis supra impressis 

 subtus elevatis, fructibus secus pedunculos canescentes terminales 

 ssepius fasciculatos folia subduplo superantes ternatim aggregatis, 

 cupulis cupuliformibus 5 lineas diametro canescentibus intus cano- 

 sericeis squamis distinctis adpressis, glandibus glandaceis lucidis 

 ovoideis acuminatis 6 lin. diametro 5-6 lin. altis.
