In the summer of 1917 my attention was directed hy Mr. C. C. Lacaita to a 

 specimen in the Linnean Herbarium from South Africa named Ecldum 

 argenteum, which proved to be a species of Lohostemon that could not be

argenteum, Buck), witli which Linnc had supposed it to be identical. F 

 enquiries made I am informed that there is no specimen like it in the South 

 African or Bolus Herbaria, so that the following description of this new 

 species is entirely based upon the unique specimen in the Linnean Herbarium 

 which was collected at least 147 years ago, and does not appear to have been 

 found by any collector since that date. Its chief characteristics are the 

 ascending narrow silvery leaves with recurved tips, compact head-like cymes, 

 and especially the large sepals.
