scription of which (p. 60) is satisfactory. Our plant is acaulcscent 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 (Enothera 

 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.
