_ The Order ZycorHyLtLEa was proposed by Mr. Brown, 
in the Appendix to Flinders’s Voyage, and adopted in the — 
Prodromus of Mons. Decandolle; who describes it as com- 
ing between Rutacem and OxauipEem; differing from the 
former by a single style, seed without arillus, a foliage 
more uniformly opposite and furnished with stipules; from 
the latter by the structure of the seed-vessels, which do 
not consist of the elastic cocculi so remarkable in Rutacew. 
The present species is native of South America; and — 
was Cultivated by Miller, in the Chelsea Garden, as far back — 
as 1752. ‘The popular name of “ Caltrops” has been adopt- — 
ed from the seed-vessels of the common European species 
(Trisuwus terrestris), well known to Gerarde and our old- 
est herbalists. ‘he thorns of the seed-vessels are compared 
with the spikes of the instrument called “ Caltrops.” 
It is with pleasure we find the consummate talents, sa- 
gacity, and industry, with which M. Decandolle is indis- 
putably endowed, directed to an object that they may 
accomplish to the great advantage of science, instead of — 
struggling with impossibilities; and we congratulate our’ 
readers on the appearance of the first volume of the Pro- 
dromus of a general system, in which the known species 
will find a place in their respective divisions, with only a 
short notice of the distinctions, and one or two select 
synonyms. , ;

cultural Society.
