ON A NEW INDIAN OAK. 



Apart from the question of the claims of Castanea and 

 Castanopsis to generic rank, my own views regarding which are 

 well known, the consolidated styles of the tree under consideration 

 show that it does not fall under either group. As it has, more- 

 over, unless I err, never been published, I desire to dedicate it to 

 the memory of its discoverer, whose untimely death is a sad loss 

 to Indian botany, Mr. Kurz's knowledge having been very sound, 

 and his experience as a working naturalist unusually wide. 



1. QuERCUS (Cyclobalanus, Encleistocarptcs) KuRzn, sjj. nov. — 

 Kamulis teretibus cortice subsuberoso glaberrimo crebre lenticellato 

 obductis, foliis membranaceo-coriaceis lanceolatis integerrimis 

 attenuato-acuminatis supra lucidulis subtus ochraceo-pallentibus 

 costa subtus prominula venis primariis ad utrumque latus 10-14 

 angulo 62° egressis arcuatis juxta marginem anastomosantibus 

 cum secundariis tertiariisque vix tenuioribus reticulum densum 

 utrinque elevatum elibrmantibus 4-5 x^oU. longis 1-1 i poll, 

 latis petiolo 4-lineali, fructibus pluribus secus ramum 2 lin. 

 diametro sessililibus subdistantibus, involucro ovoideo cinereo- 

 tomentoso pollicem longo 6-7 lin. lato \ lin. tantum crasso zonulis 

 concentricis 6 baud distincte squamosis valde sinuato-curvatis 

 marginibus erosidis verrucoso-mcrassatis pr^edito demum irregu- 

 lariter fisso, glande demum libera ovoidea castanea tenuiter fulvo- 

 sericea basi hilo carpico ruguloso paulo pallidiore totam basin 

 occupante notata, styhs in columnam brevem stigmatibus in 

 globum coalitis, cotyledonibus intricato-plicatis. 



In Assamia coU. b. Kurz. (Herb, propr., n. 20495.) 

 The species stands next to Q. Blumeana, Korth., and 

 Q. encleistocarpa, Korth., of which the second alone is known to 

 me from specimens, but it is very distinct from either. The fruit 

 is more like that of Q. lanceifolia, Koxb. and Q. /issa, Champ, 

 (with which latter it agrees in its cotyledons), except for the 

 close grey down of the involucre, which is like that of the callseo- 

 carpoid Castanopses ; but both those species belong to Pasania, 

 Chlamydohalanus. 



2. Quercus Grijithii, Hook. f. & Th. — I am now of opmion, 

 after the comparison of very good Khasia specimens, that this is 

 truly distinct fi'om my Q. Fabri, from which it differs by the more 

 closely placed costules each running out into a sharp tooth, and 

 the paler more convex cup-scales. In Q. Fabri the lobules into 

 which the costules run are quite rounded and obtuse, and the cup- 

 scales are of a deep reddish brown, very flat and appressed. The 

 acorns of both are quite alike. 



3. Querciis scmiserrata, Koxb. — According to A. DeCandoUe, 

 Sir Joseph Hooker considers this identical with Q. annidata, Smith, 

 which is certainly not different from Q. glauca, Thimb. This is a 

 view in which I am unable to concur. Instead of the glaucous or 

 glaucescent under surface of those of the latter tree, the leaves of 

 Q. sejuiserrata have a yellowish submetallic tinge : again, the fruit 

 is very different, and at least double the size of that in any form 

 of Q. glauca; the much thicker cupule is more or less w^oolly-
