This rare, though not very interesting, plant is a native 
of the high parts of the Cordilleras lying between Valpa- 
raiso and Santiago, where it was collected for the Horticul- 
tural Society by Mr. James M‘Rae. Our drawing was 
made in the month of May 1828, from a plant growing in 
the Chiswick Garden, where it is cultivated in the frames. 
That the genus now called Polygonum comprehends 
several groups of plants requiring to be separated as 
distinct genera, is, we think, quite apparent from the very 
* So called on account of the numerous geniculations of the stems of 
some of the species (wads, many, and yo», a knee), according to De Théis 
and: others : but this derivation is perhaps applicable to the herb weruyorarer 
of the Greeks, which is supposed to have been the Convallaria latifolia of 
modern Botanists, rather than to the subject of the present article. : The 
mwodbyevey of the Greeks, under which were comprehended several species of 
the genus Polygonum, is said by the lexicographers to be derived from 
veAvyevs, fruitful, productive; and Scribonius Largus expressly declares 
that “ herba, que, quia multa est, et ubique nascitur, weruyoror appellatur.
