Another little flower that 1s readily recognised as one of the 
mustards. It is not as luxurious in its taste as the preceding 
species and is content with the less rich soil of rocky places 
and hillsides. 
BLOOD-ROOT. INDIAN PLANT. (Plate XC VIZ) 
Sanguinarta Canadeénsts. 
FAMILY COLOUR ODOUR RANGE TIME OF BLOOM 
Poppy. White with yellow centre. Scentless. Genera. April, May. 
Flowers: terminal; solitary ; growing on a naked scape. Calyx: of two 
sepals. Corolla: of eight to twelve petals. Stamens: numerous. Pisti/ : 
one. Fruit: an oblong pod. Leaf: one only, from the base; rounded; 
palmately-lobed; veined. oofstock: fleshy and, as the stalks, containing a 
blood-red juice. 
The blossom of the blood-root is one of the most carefully 
guarded of Nature’s children, Its sweet loveliness is not thrust 
ruthlessly upon the world to make its way the best it can. 
The leaf is carefully wrapped about the flower bud, and not 
until the former is assured of the temperature and the fitness 
of the surroundings, does it unfold and allow the scape to 
stretch upward bearing the beautiful flower. And how fair it is 
only those can know that have seen it unfold its pure, spotless 
petals. Indeed, it is too fragile for the rocky hillsides. The 
winds carry off its petals and those that seek it often sigh to find 
it has already perished. 
It seems strangely incongruous that the fluid of this plant 
with its unusually pure blossom should have been used so ex- 
tensively by the Indians to decorate their faces.
