Widely distributed tliroughout the tropics and in some subtropical areas. I 

 adopt the name E. hirta^ Linn., for this species instead of E. pilulifera because, 

 besides being printed on a previous page to the latter, it is most certainly the plant 

 described by Linnasus and preserved in his herbarium under that name, whilst, 

 although this plant is accepted by Boissier and others as being E. pilulifera, Linn., 

 it is clear that that acceptation has l)een based upon the figure in Burnmnu's Thex. 

 Zeylan. 224, t. 105, fig. 1, which Linnjeus has incorrectly roferred to as a synonym 

 of E. pilulifera. For it is certain that Linnaeus considered E. hirta and E. piluli- 

 fera to 1)6 distinct species. In his herbarium are two specimens, named in his own 

 handwriting " 18 hirta " and " 19 pilulifera." Comparing these specimens with the 

 descriptions, it is evident that the latter were made from the former. Linnaeus 

 describes E. hirta as having pointed leaves and pilose stems, but omits these 

 characters I'roin the description of E. pilulifera, implying (as was his custom) that 

 it does not possess them. This distinction completely accords with the specimens of 

 these species in the Linnean herharinm. The fipui-e of l')Urmann, however, referred 

 by Linnaeus to E. pilulifera disagrees with this distinction, having hairy stems and 

 acute leaves, and merely represents another form of E. hirta. The type specimen of
