We can find no valid differences between von Seemen's two species and it would 

 appear that he must have overlooked his Q. cleistocarpa when describing Q. Wilsonii. 



The summit of the acorn is flat or even depressed in imperfectly developed 

 fruits, but usually it is shghtly raised. Sometimes the upper part of the cup does not 

 properly develop, and in that case a greater or lesser part of the acorn is exposed and 

 the appearance of the fruit is changed. The species is obviously very closely re- 



Pasania Oersted in Kjoebenh. Vidensk. Meddel. XVIII. 81 (Bidr. Egesl. Syst. 73) 

 (excl. sect. Chlamydobalanus) (1866). — Prantl in Engler & Prantl, Nat.

 There can be little doubt that the four genera enumerated above are so closely 

 related that they cannot be considered distinct, and as Lithocarpus is the oldest of 

 these generic names, it becomes, as already pointed out by Nakai, the name of the 

 genus, the type of which is L. javensis Blume. The reason why Koidzumi rejected 

 Lithocarpus and uses the name Synaedrys is apparently the supposed existence of an 

 earlier homonym which he quotes as " genus Styracaceorum in Cat. Buitenzorg. 

 1823." We are, however, unable to find in Blume's Catalogus van . . . Gewassen te 

 vinden in 's Lands plantentuin te Buitenzorg of 1823 any mention of a genus Litho- 

 carpus. The first place where we find this name mentioned is in Endlicher's Genera 

 plantarum, 743 (1836-40) under Styrax a. Eustyrax as " Lithocarpus Blume Hart. 

 Buitenz. non Fl. Jav. St. Benzoin Dryand.," and Miquel refers to it in 1855 in his 

 Flora Indiae Batavae, I. pt. 1, 865, adding after Lithocarpus Bl. Bijdr. p. 527 " non 

 homonymum ejusdem genus Styracem Benzoin spectans." Apparently Lithocarpus 

 Blume Hort. Buitenzorg is an unpublished name and being, moreover, a synonym 

 of Styrax, it cannot, even if it should have been published earlier, invalidate Blume's 

 Lithocarpus of 1825.
