926 SYNGENESIA. SUPERFLUA. Gnaphalium. 
Rymny river, Monmouthshire, for the space of at least twelve miles. 
Such are the stations given by Ray, and repeated by Hudson; but the 
former seemed to doubt its being a native. (We learn from FI. Brit, that 
it has, however, recently been discovered by the Rev. T. Butt, near a 
rivulet in the heart of Wire Forest, Worcestershire; and by Dr. Salt in a 
meadow at Longdon, near Litchfield. E.) P. Aug.*' 
G. dioi'cum. Runners trailing: stem unbranched: flowers in a simple,

In the barren plants the heads almost globular: in fertile ones nearly 
cylindrical. Linn. Ripe seeds are rarely produced, as is the case with 
many plants which stole at the root. Root woody, brown, with a few 
stiff fibres. Runners several, creeping, leafy, from the crown of the root. 
Root-leaves in a thick tuft, oval at the end, tapering below into a long 
leaf-stalk, green and slightly hairy above, underneath white with a thick 
cotton; stem-leaves numerous, strap-shaped, half embracing the stem, 
green above, white and cottony underneath. Stems upright, simple, 
three to seven inches high, white, cottony. Heads three to eight, on 
short fruit-stalks. Calyx scales blunt, the outer short, green, cottony ; 
the inner widening upwards, long, smooth, shining, white, frequently 
tinged with purple; in the barren plants shorter. Seeds short; down 
sessile, with simple rays, that of the fertile plants longer than the calyx, 
that of the barren plants not exceeding the calyx. Woodw. Blossom 
white, purple, or reddish. 
(A larger variety, with leaves broader and woolly on both sides, has been 
sent from the Isle of Skye, by Mr. J. Mackay. FI. Brit. This plant is 
said to preserve its habit on cultivation, and has been designated G. hy- 
perboreum. We have been favoured with specimens from the original 
station by Mr. Winch, and observe in our herbarium G. dioicum , enlarged 
by cultivation, with a similar appearance. E.)

ach. Barton. Frequently cultivated as an ornamental plant in the gardens both of 
England and the Continent; said to have been introduced from America about the 
sixteenth century. Its enduring quality renders it valuable through the winter; (for, 
though inferior to several exotic species in brilliancy, its flowers equally retain their 
pristine appearance for years. This species appears to be dioecious. Vid. Brown, in 
Linn. Tr. xii. 128,—The fact that many species of the Syngenesia Class are dioecious, or 
have the barren and fertile flowers on distinct plants, not only escaped the observation of 
Linnaeus, but of his most enlightened successors : and even Jussieu points out G. dioicum 
as “Species una dioica insigni e.vceptiojie. ,> For a further illustration of this curious 
subject, vid. Linn. Tr, vol. xiii. E.)
