SYNGENESIA. iEQUALIS. Bibens. 
Leaves with opposite distant serratures. Flower-leaves very entire. Seeds 
with four awns, two of which are larger. Woodw. Stem a little hairy, 
(two feet high, branched. E.) Calyx segments egg-spear-shaped, with 
black lines. Blossom and summits yellow. Anthers brown. Germen 
pyramidal, quadrangular. 
Nutant Double-tooth or Bur-marigold. (Welsh: Graham ogwydd. 
E.) Wet ditches, marshy places. A. Aug. —(Sept. E.) 
Var. 2. Flowers with radiated florets in the circumference: (and thus dis¬ 
tinguished from Coreopsis. E.) 
FI. Dan. 841— Barr. 1209—11. Ox. vi. 5. 22. 
Frequently on the same plant with var. 1. Woodw., as in the lower part of 
fig. FI. Dan. 
Coreopsis Bidens. Linn. In England, and very frequent in Ireland. R. Syn. 
187. n. 2. About Tarporley and other places in Cheshire. Hudson. 
Norfolk, but not common. At Ditchingham. Mr. Woodward. (Road 
side between Llanyngenel and Rhyddpont, Anglesey. Rev. Hugh Da¬ 
vies. E.)

Seems to differ in no other respect than in its dwarfish size and wanting the 
serratures on the leaves, which probably would appear if the plant 
acquired a more expanded growth in a moister atmosphere. Var. 2 
merely exhibits an unusual degree of luxuriance. 
B. minima. Linn. In the fish pond on the moor near Somerset Bridge, 
Surry. Dill, in R. Syn. In a splashy rivulet at the bottom of Tittensor 
Common, Staffordshire; and also near Birmingham. Stokes. 
B. triparti'ta. (Leaves tripartite : seeds upright, with two or three 
bristles : calyx leafy at the base : bracteas unequal. E.)

Ger. Em. 711. 1— Park. 595. 7 — H. Ox. vi. 5. 20. 
Leaves , segments deeply serrated, the middle one much the largest. Calyx, 
scales oval, fringed with hairs, the inner smooth, with yellow membra¬ 
nous edges. Woodw. Flowers terminal, yellow, (nearly upright, uni¬ 
form, tubular, smaller than those of the other species. Stem upright, 
two or three feet high, branched, expanding, leafy, bluntly four-sided, 
furrowed, smooth. Leaves opposite, smooth, sometimes with five seg¬ 
ments. E.) 
Trifid Double-tooth. Water Hemp. (Bur Marygold. Welsh: 
Grahan cir-rhan. E.) Marshy and watery places. A. Aug—(Sept. E.)* 
Var. 2. Dwarf. 
Fl. Dan. 312, ( the right hand figure.') 
Only a starved plant, but its upright flower, and the incipient divisions on 
the leaves, sufficiently shew to which species it belongs. 
* (A dye may be prepared from this plant, with alum, to stain cloths yellow. Lightfoot 
states that in chemical qualities it much resembles the celebrated Verhesina acmela , and 
therefore infers the probability of its proving serviceable in calculous complaints. E.)
