Of this rare and remarkable plant, it may be said that the stems 

 ' and foliage resemble those of some Loasa or Bartonia, the in- 

 florescence that of an Echinops^ while the fructification, as far 

 as I know, is quite peculiar, Lagasca, the only author I believe 

 who has, hitherto, had the opportunity of examining the plant, 

 refers it doubtfully to Boraginece, Lindley to Santalacece with 

 equal uncertainty, while our friend Dr Arnott considers it rather 

 a Thymeleous plant, or ** probably sui Ordinis,'^ in which he is 

 very likely correct.
