indicate synonyms and he refers it to Andropogon Grayia. This 

 latter is found on page 91. Here we read : 



''ANDROPOGON Lin. 



****** 



" Grayia Stcud. Zeylon. 

 " Grayia zeylanica. Anwtt. 



" Schizachyrium zeylanicum. Xt^cs in JJ^ig/it. hrb." 

 There is no earlier publication o{ Atuiropogon Grayia Steud., 

 and Schizachyriinn zcylaincinn Nees was not published until 

 1855/ and even then only as a synonym under Andropogon 



Pseiidograya. 



Grayia Arnott in Steudel's Nomenclator is therefore given on 

 page 91 as a synonym of a 7101/101 njidinii, which has another 

 nomen imdiim as a synonym, and on page 705 it is published as 

 a noDicn uudum with a nomen nudum as a synonym. Publications 

 of this kind nobody now-a-days holds as valid. 



What threw Dr. Greene off the track was perhaps the fact that 

 Hooker and Arnott in their original publication of Grayia men- 

 tioned an earlier Crrtj'/^?, referring to Wight's no. 2033. Wight's 

 Catalogue was never printed. Duplicate copies were sent out I 

 think in 1833. Even if this by somebody would be regarded as 

 a publication, Grayia e/igans Arnott (note : not G. ceylanicd)\sdX 

 hesta. nomen nudu7/i, for opposite the number 2033, this name only 

 is given. " Gray a e/cgans '' wrs afterwards properly published 

 by Steudel,- who stated that in his Nomenclator he had confused 

 it with ScJuzacJiyriuni zeylanicum. Grayia of Steudel's Nomen- 

 clator was therefore intended to be the same as the unpubhshed 

 Grayia of Wight's catalogue. 



Until somebody can show me that there is some other Grayia 



published before 1840, I feel obliged to reject Ercmoscviium and 



shall be pleased to use for the two Chenopodiaceous shrubs of 



the Rocky Mountain regions that time-honored name Grayia 



Hook. & Arn.
