 oblong', toothed, notched above, with a short 

 abrupt point. The flowers are yellow, blue, or 

 purple, in .1 raceme of many flowers, the flower- 

 stalks not so lonjr as the calyx, the main stalk 

 lonjfer than the leaves. The pods are flattened 

 in a loose spiral of 2-3 turns, downy, the hairs 

 close. The plant is 1-2 ft. in height. It flowers 

 from Mav to .•Xuijust, and is a herbaceous per- 

 ennial. 



Crimson Clover (Tn'folium incanialum, L.).—

 fields, &c. The plant has an erect habit, with 

 slender stems, and is downy or softly hairy with 

 spreadinjj hairs, the leaves shortly stalked, the 

 leaflets inversely egg-shaped or heart-shaped. 

 The stipules are egg-shaped, blunt, and hairy. 

 The flowers arc in a long, cylindrical, later egg- 

 shaped head, crimson, terminal, on stalks, the 

 calvx teeth not so long as the corolla, lo-vcined, 

 and hairy, spreading in fruit, and the mouth is 

 also hairy. The petals do not fall. The wing 

 is longer than the keel, the latter springing back 

 into position af^er it is depressed by insects, and 

 the stamens are exposed. The stamens are dia- 

 delphous. The filaments have swollen tips. The 

 stvie is thread-like. The pod is stalkless, i-seeded. 

 The plant is 6-18 in. in height, and flowers in 

 June and July, being a herbaceous annual. 



Leafless Yellow Vetchling (Lathyrus Aphaca, 

 L. ). — The habitat of this plant is cornfields, waste 

 places, gravel pits, and about hedges and road- 

 sides. The habit is climbing, the stem weak. 

 The leaves are tendrils, and the stipules, which 

 are large, egg-shaped, spear-shaped, nerved, do 

 the work of the leaves. The first and second 

 leaves in the seedling are scale-like and 3-lobed, 

 with awl-like points, the third and fourth com- 

 pound, with one pair of leaflets and stipules, and 

 an awl-like tendril. The fifth and later leaves are 

 awl-like points and stipules. The point becomes 

 a tendril above. The flowers are pale yellow, 

 single, rarely on long stalks, erect. The lobes 

 of the calj'x are green, linear, about as long as 

 the corolla. The pod is sickle- shaped, broad, 

 nearly erect, beaked, netted, and the 6-8 seeds 

 are smooth and flattened. The plant is 1-3 ft. 

 in height, and flowers in June and July, being 

 a herbaceous perennial. 



Tuberous Pea (Lathyrus luberosus, L.). — This 

 plant is a denizen, found in cornfields. The plant 

 is of climbing or trailing habit. The rootstock 

 is creeping, the rootlets tuberous. The stem is 

 angled, not winged. The leaflets (one part) are 

 inversely egg-shaped, with spreading nerves. 

 The leaf-stalk and tendrils are stout, the stipules 

 are large and half-arrowshaped. The flowers 

 are borne on long flower-stalks, 2-5, crimson, in 

 a raceme. The bracts are awl-like. The ultimate 

 flower-stalks are longer than the calyx, the latter 

 with teeth, triangular. The pod is .smooth, netted, 

 the seeds smooth and round. The plant is 2-4 (i. 

 in height. It flowers from June to August, and is 

 a herbaceous perennial.

 chiefly on a chalky soil. The habit is erect. The 

 stem is rough, simple, finely furrowed, round. 

 The leaves have the lobes arranged each side of 

 a common stalk, with leaflets divided nearly to 

 the base, lancc-shaped, coarsely toothed, the base 

 running down the stem. The flowerheads are 

 white or pink, in shortly-stalked umbels with 

 2-4 rays, the bracts membranous. The branches, 

 bearing 5 fruits, with prickles in 2-3 rows, rough, 

 are 5-seeded. The plant is 6-18 in, in height, 

 and flowers in Jvuu- and July, being a herbaceous 

 annual.

 Huds.). — The habitat of this plant is fields, 

 hcdgebanks, roadsides, waste places, and corn- 

 fields. The habit is erect, the stem roughly hairy, 

 much-branched, solid, with angles, bearing nume- 

 rous leaves, once or twice pinnate, the leaflets 

 loose, lance-shaped, cut or coarsely toothed. The 

 flowers arc white or pink, in terminal stalked 

 umbels, with 2-8 rays, irregular. There is an 

 involucre of one bract or none. The oblong fruit

 and small green flowers in a cyme, 3-9. The 

 leaves are 6-8 in a whorl, linear, strap-shaped. 

 The plant is lighter green than the Common 

 Cleavers, and the fruit is pale. The stem is 

 rough, and the leaves have turned-down prickles. 

 The plant is 1-3 ft. in height, and flowers in July,

Cornfield Galium (Galium Iricorne, Stokes). — 

 The habitat of this plant is cultivated fields, corn- 

 fields, &c. The habit is similar to that of Cleavers, 

 the stem prostrate, then ascending and spreading. 

 The leaves are narrow at the tip, 6-8 in a whorl, 

 linear, lance-shaped, rough, the prickles turned 

 back at the margin, and the 3 small creamy- 

 white flowers are in a cyme, on axillary flower- 

 stalks, shorter than the leaves, the middle one 

 only perfect. The fruit is granular, large, white, 

 and the fruit-stalk is turned back eventually. 

 The plant is 4-12 in. in height, and is in flower 

 from June to October. It is a herbaceous annual. 



Cornfield Woodruff {Aspenila aruensis, L.). — 

 This plant is an alien or casual, found in cornfields
