The species was named after Dr. Th. Valeton Sr. the celebrated 

 author of the 11 first numbers of the Bijdragen tôt de kennis der Boom- 

 soorten van Java, the materials for which were coliected by the late 

 Dr. S. H. KooRDE rs. 



VII. DIPLACHNE P. B, 



Two species of this genus occur in Java. The first, a new one, wiil 

 be described hère beneath, the otiier, much commoner than the first, is 

 the plant which is described in many colonial floras under the name of 

 D. fusca P. B. 



D. fusca P, B. is the same as Festuca fusca L. (Spec. Plant. Ed,2,p. 

 109), which was described by its author as a Palestine grass with a 

 secund decompound panicle and 16— 24-flowered spikelets about25 mM long. 



But the plant described in the colonial floras as Diplachiie fusca 

 has an equalsided simple panicle of racemed spikes and 4 — 11-flowered 

 spikelets of 6 — 12 mM long, so that it cannot be identical with the species 

 described by Linnaeus. Hence the name 0//7/ac^/2£y'wsca cannot be retained 

 for it but should be replaced by D. polystac/iya as the grass in question 

 was first described by Forskal (Flora aegyptiaco-arabica, p. 23) under the 

 name of Broinus polystachyos Forsk. 



The synonymy of the species is as follows: 



Diplachne polystachya (Forsk) Backer = D. fusca Auct. 

 plurim. (haud P.B.) =Bromus polystachyos Forsk. 



Diplachne fusca P.B. =::Festuca fusca L. A plant not 

 occurring in the Dutch Indies.
