the retuse apex. These broad and silvery hyaline scales, of extreme 
thinness and delicacy, are externally, as it were, diymous, from the 
introflexion of their thickened axis or costa. In the inner pales the 
base becomes more and more thickened and corneous; like the outer 
squame of the partial involucres, this corneous axis making a strong 
contrast with the diaphanous margins. This genus should stand 
between Skirrophorus, from which it differs by its very remarkable and 
persistent squamæ and paleæ (both of the glomerule and of the. one- 
flowered capitula), as well as in its whole habit, and Hyadolepis,* from 
which it is distinguished by the paleaceous general receptacle, the 
glabrous pyriform achænia, and the total absence of pappus.

Zuccarini estimated the amount of species in his herbarium at 30,000; 
among which were many specimens received from Botanic Gardens, such 
as those of Erlangen, Munich, Berlin, Vienna, Paris, Padua, Verona, 
Milan, Kew, Lówen, Naples, Bonn, Montpellier, and St. Petersburg. 
Owing to his lamented early death, there was only found a numerical 
list of the genera, but none of the species, of this very. considerable 
botanical treasure.T 
* The examination of Cunningham's specimens of Hyalolepis, DC., in the 
Hookerian Herbarium, confirms, in most respects, the characters given by De Can- 
dolle, of the correctness of which, owing to the state of the specimen, he was 
uncertain. The narrow hyaline scales of the general involuere are entire, and the 
ish eosta is evanescent long below the summit. The general receptacle is flat 
and epaleate. The involucre of the capitula, which are sometimes two-flowered, is 
formed of three similar lanceolate-spathulate scarious scales, with a thin costa, firmly 
coalescent below the flower into a short and indurated terete base, or partial recep- 
tacle, which separates at maturity from the general receptacle. The corolla is 
5-toothed, and the anthers are manifestly bicaudate, The very immature achænia 
are linear, and some of them apparently want the single delicate bristle of the pappus. 
+ We extract from this list a very general sketch, arranged according to Endlicher's 
method, as it may be of interest to know the numerieal extent of an herbarium, raised . 
by a continental botanist, during the last deceuniums, by means of that system of
