SYNGENESIA— POLYGAMIA-iEQU. Cuicus. S91 



4. C. Forsteri. Branching Bog Plume-thistle. 



Leaves slightly tlecurrent, pinnatifid, spinous ; downy he- 

 iieath. Stem panicled, hollow. Calyx ovate, rather cot- 

 tony ; outer scales spinous. 



In boggy woods. 



Near Fiant, Sussex, two miles from Tonbridge Wells. Mr. T. F. 

 Forstcr. 



Perennial. July, August. 



Root tapering, not creeping. Stem 3 or 4 feet high, erect, leafy, 

 angular, farrowed, not winged ; more or less branched and pa- 

 nicled at the top. Leaves rather deeply pinnatifid, with pardy 

 palmate, spreading lobes, tipped and fringed with rather small 

 spines ; the lowermost tapering at the base, and hairy or downy 

 on both sides ; those about the middle of the stem decurrent to 

 a small extent, cottony beneath ; uppermost gradually smaller 

 and narrower, oblong, undivided, heart shaped and clasping at 

 the base. FL 2 or 3 together at the end of each branch, on 

 downy stalks, erect, rather larger than the preceding, and of a 

 tine deep crimson. Cal. ovate, beset with a small portion of 

 loose deciduous web ; outer scales spinous, with downy edges, 

 like the last ; inner tapering to a long, narrow, coloured point. 

 Seed-down delicately feathery. 



The fructification of this plant most accords with that of the two 

 last species j while the herbage and habit approach some of the 

 following, or rather the exotic Cnicus rivuUiris, IVilld. n. 30, 

 though very distinct from that, and, as far as I have been able to 

 determine, from all other described species oi Cnicus or Carduus. 

 Mr. Forster observes that it increases in his garden by the root, 

 very sparingly by seeds ; perhaps from some ))artial imperfec- 

 tion in the flowers of the plants he happened to introduce. 



5. C. eriophoriis. Woolly-headed Plume-thistle. 



Leaves sessile, pinnatifid, with two-ranked spinous seg- 

 ments ; bristly above. Calyx globular, densely woolly, 

 leafy at the base.
