extremely narrow, scarcely subtle-ciliolated, those of the outer 
row less than half the length of those of the inner series, but the 
latter still shorter than the capillulary bracts of the receptacle 
and hardly as long as the fruit. 
A closely allied species, namely Centaurea solstitialis (Linne), 
the St. Barnaby’s Thistle, which is of the same geographic range 
in its native countries, has also already found its way into the 
Colony Victoria for permanent domiciliation ; it remains however 
as yet less frequent, though in the countries at the Mediterranean 
Sea it seems more common than Centaurea Melitensis, which does 
neither claim British natality in the way of Centaurea solstitialis. 
The latter may be recognised already by the terminating spinules 
of the involucral bracts being considerably longer than the 
lamina of bracts, also by the outside darker colour of the fruits, 
with less attenuation at the base, and by the longest pappus- 
bristlets about doubly exceeding the length of the fruit, irrespec- 
tive of some minor characteristics.

KENTROPHYLLUM LANATUM. 
De Candolle and Duby (from Necker), Carthamus lanatus, Linn4. 
The Saffron-Thistle.

the vernacular from the affinity to the spurious Saffron-Plant,
