These two specimens do not materially differ from the plant here 
figured, which was received by me, under the same name of “ Rat-

riosa, graminifolia or spheroidea; but neither of them agrees well 
with the description of scariosa.* For the present, these remarks 
are thrown together principally with a view to elicit information re- 
specting the medicinal species of this beautiful genus of plants; and as 
the plate here given, is a supernumerary one in this number, the 
above imperfect account will, it is hoped, be excused.
