24 ELEMENTS OF BOTANY. 



V. AQUILEGIA, COLUMBINE. 



Also mistakenly called Honeysuckle. 



Sepals 6, petal-like, all similar. Petals 5, all similar, each 

 consisting of an expanded portion, prolonged backward into 

 a hollow spur, the whole much longer than the calyx. Pistils 

 5, forming many-seeded pods. Perennials, with leaves twice 

 or thrice palmately compound, the divisions in, threes. 



(A. Canadensis), Wild Columbine. Flowers scarlet without, 

 yellow within, nodding ; spurs rather long and hooked. 



GRUCIFER^, MUSTARD FAMILY. 



Herbs with pungent, watery juice and alternate leaves with- 

 out stipules. The sepals are usually 4, often falling off early ; 

 the petals 4, arranged in the form of a cross ; stamens 6, the 

 2 outer ones shorter than the 4 inner ones. The fruit is 

 generally a pod, divided into two cells by a thin partition 

 which stretches across from one to the other of the two 

 placentae. The flowers throughout the family are so much 

 alike that the genera and species cannot usually be deter- 

 mined without examining the tolerably mature fruit. 



I. DENTARIA, TOOTHWORT, PEPPER-EOOT. 



Pod lance-linear, flatfish. Seeds in one row, wingless ; 

 seed-stalks broad and flat. Stems naked below, 2-3-leaved 

 above, from a thickish, more or less knotted or interrupted 

 rootstock. Plowers rather large, in early spring. 



a. (D. diphylla), Two-leavkd Toothwort, Pepper-eoot, 



Crinkle-eoot. Rootstock long, often branched, toothed, eatable, 

 with a flavor like that of cress or radish ; stem-leaves 2, close together, 

 each of 3 ovate-diamond-shaped and toothed or crenate leaflets ; the 

 root-leaf like the stem-leaves. Flowers white. 



b. (D. laciniata), Crow's Foot. Rootstock short, necklace- 

 like ; stem-leaves 3-parted ; root-leaf often absent ; flowers white or 

 rose-color.
