This is another of the many interesting novelties of this tribe, for which we are indebted to our 
valuable correspondent Professor William Jameson of Quito. It possesses a remarkable character 
in the situation and direction of the involucres, for they are placed at the base of the upper margin 
of the pinnz, all pointing upwards, and as it were in the centre of the plant, and taking the place. 
of lacini, which exist in the same situations in the sterile pinnz.
