 Fig. 2, seedling at the end of the first season' s growth. Fig. 3, second year 

 from the seed. Fig. 4, a 9 top of flowering plant early in May, stipular eminen 

 ces plainly shown at base of lower leaf; b, flower with most of the stamens re- 

 moved. Fig. 5, part of stem with fruit, late in July. Fig. (>, stipules; tf, part 

 of fertile stem with amplexicaul petiole of lower leaf, showing tubercular stipu- 

 les; />, caudex with portion of radical leaf petiole, old bud-scales dissected back 

 and showing stipules at base enveloping the rudimentary hibernaculum, depau- 

 perate leaf protruding, as observed in June. Fig. 7, stipules as bud-scales; a, 

 bud-scales at base of fertile stem, early in May; b and/, buds formed in the axil 

 of a radical leaf, as they appear in October or November, with outer scales dis- 

 sected back; />, one of the bud-scales surmounted by a depauperate leaf; <\ same 

 with merely fimbriate attachment; Fig 8, horizontal root fiber, with adventi-

 third leaves are produced; a, part of upper portion of stem showing attachment 

 of sessile leaf, floral bract, and fruit soon after anthesis; /> and € % same with
