Most nearly allied to C. rhamnifolia, Miq., but differs by its 



more rigid foliage, the shape of its involucre, the distinct zonate 



arrangement of the processes terminating in sharp smooth prickles, 



and the three nuts. 



6. QuERcus DiscocARPA, Hauce. — Fine specimens of this, com- 

 municated under nos. 3629, 11447, and 11486, hb. Bogor., enable 

 me slightly to correct the diagnosis as follows : — Aculeis saepe 

 3-4 lin. longis acicularibus refractis, glande -matura cum cupula 

 non connata. Unfortunately, not one of the fruit I have opened 

 has enabled me to ascertain the cotyledonar structure. But, as I 

 now know the species, I believe it must certainly be placed amongst 

 the Castanopses, near C. ecliidnocarpa, rather than amongst the 

 Pasania, Chlamijdobalani, where it has hitherto lain in my herbarium. 

 So long, therefore, as the genus Castanojms is admitted, the species 

 must figure as C. discocarpa. On this subject, I am' gratified to 

 observe a growing disposition on the part of those writers who 

 have good opx3ortunities of studying Asiatic Corylacece to concur in 

 the view I have long advocated as to the reunion of both Castanea 

 and Castanopsis with Quercus. Mr. Kurz some time ago wrote : — 

 " The differences between these genera are simply artificial ones:"* 

 and, in a letter I received from Dr. Scheffer, he observes, — " Du 

 reste, j'accepte pleinement votre opinion que Castanojms, Castanea, 

 et CallcEocarjms doivent etre fondus avec Quercus.'' Latest of all, 

 one of the most industrious and original of hving botanists, — Pro- 

 fessor Baillon, — than whom there are few if any less disposed 

 " jurare in verba magistri," remarks, in his recent revision of the 

 genera of the family, "Les chenes peuvent a peine se distinguer 

 generiquement des chataigniers ;"f and, whilst he unhesitatingly 

 reduces Castanopsis to Castanea, in his list of genera he puts a mark 

 of interrogation before the latter. It is strange that M. Baillon 

 should have made no reference to the very imx^ortant investigations 

 of Oersted.
