Although we have not seen authentically named specimens of Arenaria bryoides, 
Willd., we have no doubt that the Guatemala plant is at most no more than a variety of 
that species. It agrees almost exactly with the excellent description cited above, except 
that “folia enervia” is not applicable; but the meaning of this is not quite clear. 
The specimens collected by Linden (no. 938) on the Peak of Orizaba, and named A. 
bryoides, Willd., in Kew herbarium, differ from the Guatemala plant in having less 
crowded, thinner leaves, decidedly ciliate throughout their entire length, and in having 
smaller flowers with more prominently ciliate sepals.
