Epilobium paniculatum; h, in- 
terior ovary; f, a grown capsule; 
g, tube of calyx above the ovary; 
e, one of the bifid petals; 7, one

silken hairs.

scription of which (p. 60) is satisfactory. Our plant is acaulescent or stemless; therefore, 
according to the book, the calyx tube is filiform (slender) above the underground ovary. 
This being verified by examination, there can be little doubt that the plant is @nothera 
ovata, You now see that the flowers, instead of growing upon scapes, are sessile upon 
the end of a root-stock. The apparent flower stem is the slender calyx tube and style 
consolidated. When you plucked the flower, the ovary was left under the ground. No 
wonder you could not find it. Later in the season you will find other plants belonging 
to this order; then the figures above will help you. 
The figure at the right above represents the upper part of a plant which usually grows 
in moist places. The white flowers have four separate sepals; four petals; six stamens in 
two sets, two being shorter and otherwise different from the other four, and one pistil.
