U. grandiflora J. E. Smith. Lar(^.e-flo\vered Bellwort. Less

 ments of the perianth twisted. May.

 ets. In general appearance like the other members of the

KRYTHRONIUM L. 



E. Americanum Ker. Adder's Ton(;le. Dug-tooth Violet. 

 Yellow Lii.v. Fawn Lu.v. Abundant in nearly all low thick- 

 ets on river banks, etc. Leaves two or three, oblong, spotted 

 with brown ; flowers single, drooping, brownish outside, yellow 

 inside, the segments revolute in sunshine. Bulb very deep in 

 the earth. This plant does not flower until its bulbs have reached 

 a sufficient depth. To accomplish this, the young bulbs near 

 the surface send out long runners that form new bulbs at their 

 extremities, upon which the central bulb dies. The large flow- 

 ering bulbs commonly do not send out runners. One of our 

 earliest spring flowers. The foliage disappears before midsum- 

 mer.

 and stout, bearing numerous large, drooping, orange-yellow 

 flowers, spotted inside with brown ; segments of the perianth 

 strongly revolute. An elegant species. Aug.
