The above description is compiled from that given by Dr. ^larloth and 

 from his figures o£ the plant, partly copied on PI. 5. figs, 1-2. lie appears 

 ]iot to have 6k:tQ;\\ the pLant in a vegetative condition^ as he does not describe 

 both kinds of leaves, nor if they are or are not crystalline-papillate when 

 young- The mode of growth is undoubtedly the same as tliat of M. pro.vi mvm ^ 

 M, dlsdtiun^ etc.j which I describe on p. 59^ and not quite the same as 

 dctaiUMl by Dr. Marloth, I have included this species here to contrast it 

 with AL iiToAiHtim^ from which iV. mitratiun seems to difCer by its much 

 stouter conical bodies, which arc also solitary instead of clustered. 



Dr. Marloth has placed this phint in a separate section (§ Mitrata)^ but 

 as J/, mitratutn^ M. pvoximum^ and .17, dissitum^ wliicli are certainly all 

 allied, do not differ in any way in their very peculiar mode of growth from 

 M. divoruni and M, coffnatum described here, all of these S[)eci(*s must be 

 associated tnider one group or section ; and as tliere is evidently a relation- 

 shljj between M. cllconun and M, monillj'onuej as indicated by some of the 

 branches on the plants of M. divoram^ one of which I have represented on 

 PL 5j where the internodes are much shorter than usual, so that they then 

 somewhat resemble the bead-like joints of Jl/, moniliforiiie^ it ap[)ears to me 

 that all those plants should bo placed under the section Moniliforviia of 



Haworth, as I have here done.
