the name of Herpestls for the mass of species to which it was ori- 
ginally given, and to give a new name to the H. lanigera. 
According to Martins, Calytrlplex of Ruiz and Pavon is the Her- 
pestis Monniera. 
Sphaerotheca, if I am right in the species I have thus determined, 
has, with the characters of Gratiolese (very near to those of Matou- 
rea) the habit of Scoparia. 
To Matourea I have referred several plants which, with the calyx 
and habit of Gratiola, have didynarnous stamens, a loculicidal de- 
hiscence, and the capsular valves entire, or slightly bifid. This 
leaves an artificial genus, comprising four or five species, closely 
connected in habit with Gratiola, of which it might perhaps be 
considered a section. 
Caconapea of Chamisso and Schlechtendal, though very different 
In habit, is scarcely distinguishable from Matourea in character. I 
am unacquainted with Ranaria of the same authors. 
The genus Gratiola remains confined within the limits ascribed 
to it by Brown (Prod. 435). 
Beyrichia (judging from three Bahia species gathered by Salz- 
mann, which I have referred to that genns*) and Achetaria, which 
appears from Chamisso*s descriptions to be closely allied to it, are 
remarkable by the abortion of the upper stamina, as in most dian- 
drous Labiatse and Acanthaceee, and not of the lower ones, as is 
usual in diandrous Scrophularinese. The imbricate tribracteate ca- 
lyx, and in some measure the habit, indicate a further affinity to 
Acanthacese, from which they are however well distinguished by 
the capsule and seeds. 
Dopatrium, confined to the three species mentioned below, is as 
distinct from Gratiola in habit as in character. 
Microcarpeea, Peplidium, and Limosella are ve»y nearly allied to 
each other in habit, and Peplidium has been joined by Hooker to 
Microcarpaea ; but if the manner of dehiscence of the capsule, and 
the number and form of the stamina, be really good generic distinc- 
tions in the Gratioleae (and they are very frequently the only ones), 
it is impossible not to consider these three plants as separate genera. 
Bonnaya was separated by Link and Otto from Gratiola on ac- 
count of the long siliquose fruit, a character very uncertain, and 
apparently of little importance. There is, however, a much more re- 
markable difference in the dehiscence of the fruit, which is the same
