Weicker, have however these parts of exactly the form descrihed ahove, and agree in 

 all points with the English plant, with the exception of the want of a bractea under 

 each bunch of flowers. It is however possible, from the manner in which this bractea 

 is hidden by the flowers in the English plant, that it may also exist in that found in 

 Germany, although the employment of its absence as a part of the specific character, 

 is strongly opposed to this supposition." — p. 563. 



The next species, Cuscuta halophyta, has not, we believe, been de- 

 tected in this country. It was recently discovered on the southern 

 coast of Norway, growing on succulent saline plants; and was first 

 described by Fries, in his * Novitianim Fl. Suec. Mantissa prima,' p. 

 8. Fries does not mention the scales ; but Mr. Babington has found 

 them in a specimen gathered by Dr. Blytt " on the coast of the Fiord, 

 near Christiana," who gave it to Mr. Bowman, from whom Mr. Ba- 

 bington received it. 



The following illustrations exhibit the corolla of each species laid 

 open, in order to show the form of the scales, and their position with 

 respect to the stamina ; they are copied from Mr. Babington's figures 

 in the two papers under notice : from which source are also derived 

 the characters of the four species, and the description of Cuscuta 

 epilinum. 



1. Cuscuta europ(Ba, Linn. (Sp. PI. 180). " Clusters of flowers bracteated,'' sessile: 

 scales bifid, erect, adpressed to the tube of the corolla ; tube cylindrical when in 

 flower, ventricose in fruit : calyx much shorter than the corolla. (Fig. 1). 



Keichenbach's figure of the opened corolla is shown at fig. 2. 



2. Cuscuta epithymum, Sm. (Eng. Bot. p. 378). " Clusters of flowers bracteated," 

 sessile ; scales palmately cut, connivent ; tube of the corolla cylindrical, limb 

 campanulatc : calyx much shorter than the corolla. (Fig. 3.)
