DOUBTFUL AND IMPEEFECTLY KNOWN SPECIES. 



Q. PDIVAEICATA, Lindl. in Wall. Cat. 2790; A. DC. Prodr. xvi. ii. 105, from 

 Tavoy, Wallich, is in flower only and undeterminable. The specimen presents no 

 salient character. Kurz refers it to Castanopsis rliamni folia. 



Q. GLOMEEATA, Boxb. FL Ind. iii. 660, Penang, W. Roxburgh; "leaves elliptic 

 entire polished on both sides, flowers iu long terminal glomerate spikes, acorn ovate 

 smooth half hid in the tubercled cup." Ro'cb. 



Q. JEXKIXSIANA, Senth. in Hoolc. Ic. PI. t. 1312, 1313, is a mixture of leafing 

 specimens of two very distinct plants, and the fruit of what may belong to either 

 or to a third. The latter only is from Colonel Jenkins, who gave it to Mr. Griffith ; 

 it apparently belongs to the section Lithocarpus. Of the leafing specimens, one is 

 probably a Quercus, the other probably a Castanopsis (see end of that genus). The 

 following is a description of the Quercus. 



QUEECUS SP., BentJi. in Hook. Ic. PI. 1. 1313 only ; bark of branches white, leaves 

 8-12 by 2|-5 in. elliptic-oblong acuminate entire coriaceous base acute, above bright 

 brown and polished with a raised midrib, beneath pale or whitish with 9-14 pairs of
