very distinct — of the flax fields of Europe, (Rus- 
sia! Sweden! Germany! France! England! Ireland! Spain! 
Sicily!) extends into the Canary Islands (Webb! Finlay !) 
and Egypt Satie Figari!) and has also been seen in the 
eastern parts of the United States! I have seen no speci-

flax from Ba dad,” is most probably the same thing. 
The characters relied on for a generic separation of this 
species from Cuscuta, are untenable, or are founded on mis- 
take. The calyx is deeply 5-lobed, not 5-sepaled; the cap- 
sule is constructed exactly as in the allied species ; the dissep- 
iment is complete till, at maturity, the larger, ae obcordate 
art separates from the upper substylar portion. The intra- 
stylar aperture penetrates into the capsule fe at full matu- 
rity by aslit parallel to the dissepiment and sometimes by a 
sec vaso transverse one. e stigma is, at the flowering peri- 
od, almost twice as long as the style, and at base of the same 
shickidin, slightly tapering to an obtuse point ; only in fruit, 
when the style is shrivelled, the stigma has the appearance of 
being oe haped. 
The very short style, the shape of the thick stigma and the 
sirianteies: of the stylar part of the dissepiment, indicate a close

alliance to the Asiatic species, enumerated below, though all

corolla closely coats the capsule. 
The distinctly pedicelled flowers are disposed in loose or 
compact umbelliform clusters, few-flowered or crowded, sup- 
ported by a single bract. 
The species belonging here are all Asiatic; C. Arabica ex- 
tends into Egypt, where it seems to be the most common 
f 
This group constitutes the connecting link between Zw- 
cuscuta and Callianche, another Asiatic form, in which the 
ie remnants of the styles are united.
