1906, (No. 2164). 
Near Quercus confragosa (Kina. t.71), from which the present 
plant differs in having acute scales of the involucres and the 
obscurely dentate leaves. This is still nearer Q. cleistocarpa SEEMEN, 
from which it is distinguishable by the much larger leaves which 
are obscurely dentate towards the apex, and by the much more 
prominent scales of the cones. 
Quercus longinux Hayata sp.nov. Rami et ramuli graciles fusco- 
nigricantes lenticellis minutis notati. Folia alterna ad nodos ap- 
proximate disposita petiolata oblongo-lanceolata 8 cm. longa 16 mm. 
lata apice acuminata, (acuminibus 2 cm. longis), basi acutis mar- 
gine a medio deorsum integra, sursum (preeter acumina) tenuiter 
serrata, (serris acutis aristatis), tenuiter coriacea, costis supra planis 
sulcatis, costis et venis subtus prominentibus, venis primariis 
utrinque latere 7-8 tenuissimis prope marginem evanescentibus vel 
ad apicem serrarum attingentibus, supra nitida subtus glauca, petiolis 
1 cm. longis supra sulcatis basi calloso-incrassatis. Cupula late
