placenta," and upon dissecting the capsule of the first species 
which we selected, H. parviflorum, we found, that not only 
was the capsule, but also the germen, perfectly free from 
any placenta, and entirely unilocular: and we afterwards 
ascertained that Auguste St. Hilaire had discovered that the 
same structure existed in Hypericum elodes. In H. parvi- 
florum, too, we observe the stamens not to be numerous; and, 
as far as we could judge from our inspection of dried speci- 
mens, all of them free to the base. If, then, the habit of the 
plant be also considered, there can be no question ofthe pro- 
priety of Sarothra being arranged with the Hypericinee : and 
the only doubt remaining upon our minds is, whether it 
ought not to be united with the genus Hypericum: H. parvi- 
Jlorum being exactly the connecting link. Taking, however, 
into account the mode of growth of our plant, its erect, rigid, 
dichotomous ramification, small leaves, fewer and larger 
seeds, narrow petals and the smaller number of stamens, 
we, for the present, retain the genus; — 2 species we 
thus define; 
1. S. gentianoides ; ramosissima, foliis subulatis minutissimis 
appressis, segmentis calycinis subsequalibus capsula 
lineari-oblonga duplo brevioribus.— Linn. 
Haz. Canada and the United States. 
Some of our species of this plant, gathered by Dr. Wray 
of Augusta, are from 12 to 16 inches tall, and from their 
copious wiry stems afford an illustration of the fitness of the 
generic name, from cagwtea, a Broom. 
2. S. Drummondii ; ramosa, foliis linearibus obtusis, segmentis 
calycinis erecto-patentibus inzqualibus capsula ovata 
duplo fere longioribus. (Tas. CVII.) 
Has. Near St. Louis, on the Missouri. ‘Drannindn tad is 
far less branched than the last, less slender, with much longet 
leaves and flowers, and, at first sight, bears no inconsiderable re- 
semblance to Linum Virginicum. The exact number of stamens 
is very difficult to ascertain in the dried states of the plant; 
but we have distinctly counted as many as 19 in a flower. The
