one plant to another, the abundance of their seeds, and the double power they 
- of germinating either in the earth or in the capsule. M. Vaucher says, that 
! bis fields from Dodder pretty well by perpetually breaking and dividing 
their stalks with a rake. The best method of extirpating this troublesome plant, 
:ri\ appears to be to mow all portions of the field where the Dodder has been seen 
eelop itself, and to do it before it can have produced seed. Each species of 
i attaches itself to its favourite crop, and no other will nourish it. Thus, if a 
portion of land should be infested with the seeds of any species of Dodder, if 
;i crop of wheat or grass be sown on it, the seed will come up and perish, not finding 
any plants about it which would afford nourishment to it.

Stems much branched, red or greenish-yellow. Flowers sub- 
sessile or shortly stalked, in rather compact sessile globular 
heads. Calyx funnel-shaped; segments fleshy only at the base, 
-> mi-transparent, erect, ovate, blunt, spreading at the apex. 
Corolla twice as long as the calyx ; tube cylindrical at the time of 
flowering, afterwards inflated ; limb spreading, as long as the tube; 
lobes broadly-ovate, obtuse, spreading; scales thin, rather small, 
ad pressed to the tube, distant, with rounded spaces between them, 
or sometimes absent. Stamens included. Styles 2, filiform, di- 
vergent, nearly as long as the ovary ; stigma oblong-linear. Seeds 
slightly roughened. 
Parasitical on hop, nettles, vetches, thistles, &c. Rather rare. 
Sparingly distributed over England, from Somerset and Dorset to 
York, and said to have occurred near Aberdeen. 
England, [Scotland]. Annual. Late Summer 
and Autumn. 
Stems much branched and matted. Flower-clusters quite 
sessile, at firsl about the size of peas, afterwards considerably larger. 
Flowers white tinged with red. This plant has the individual 
flowers smaller, but the clusters larger than in C. Epilinum, the 
corolla twice as long in proportion to the calyx, white tinged with 
pink, and the tube of the corolla is not inflated until the ovary 
begins to swell. The flower-heads are also much closer together 
and with the individual flowers shortly stalked. 
A form (?) (var. nefrens, Fries) destitute of scales in the corolla,
