Rhizoma crassum, repens. Caulis erectus, spithameus ad 
pedalem, teres, striatus, glaber, superne paniculatus. Folia 
pleraque radicalia, longe petiolata, cordato-sagittata, obtusa, 
crenata, glabra: caulina magis ovata, minusque petiolata: 
suprema lanceolata, subsessilia, pinnatifido-serrata. Pedunculi 
erecti, graciles. Flos mediocris. Calycis sepala 5, subro- 
tundata, patentia. Petala 5, subrotundo-obcordata, glabra, 
flava. Ovaria in capitulum subrotundum congesta. Achenia 
immatura subrotunda, compressa, stylo persistente mucronata 
terminata, glabra. 
A smaller specimen than that here figured sent by Mrs.

3 or 4 inches in length, throwing out numerous thick radicles 
from its underside.
