This series is intermediate, as it were, between tlie Sensitive and the Meticulosa, the M. casta and its 

 allies having the habit of the former but differing in the more numerous leaflets,'and the M. dolens and its 

 allies differing from the Meticulosa only in the presence of prickles, which in a few specimens are 

 exceedingly few, or perhaps sometimes entirely wanting, although a careful search has almost always 

 pointed out some small ones, which I have never found in any of the numerous species of Meticulosa.

I have seen no specimen answering to the character given; and as the flowers were unknown to Prcsl, 

 it is uncertain even to which section of the genus the plant should be referred. The habit described is 

 nearest to that of M. casta.

Delile's specimens were from the Botanical Garden of Montpellier, supposed to be of American, perhaps 



oridn. In the Berlin herbarium there is a specimen from Mexico, Ehrenberg, ^yhich agrees
