ONOSMAS OF LINNÆUS AND SIBTHORP. 393 
has pencilled on the sheet “ O. orientalis? 7, which may have led Boissier— 
as already pointed out—to suppose that the specimen stands for O. orientalis 
L., with which it has nothing to do : indeed, Linnzus expunged the orientalis 
in his later writing on the sheet. 
In my “ Piante Italiane Critiche,” no. xciii. (in Nuov. Giorn. Bot. It. 
xxxiv. pp. 26-29, 1924) I have arranged as follows the Italian forms which 
may be united under O. echioides as varieties ; they are all alike in their 
perennial root and strong woody base ; in their preference—not exclusive— 
for limestone ; in their simple or slightly branching stems; in their astero- 
trichous indumentum ; in their usually very narrow leaves ; in their sessile 
fruiting calyces, a character which completely separates them from stellulatum 
Waldst. et Kit. and less markedly from the he/veticum group ; and in their 
very small shiny nucules. 
(A) var. Column mihi = O. echioides L. sensu strictissimo = (). montanum 
Ten. Syll= 0. Javorke Simonk. p. parte. From a woody branched 
trunk spring tufts of leavesand simple flowering stems, 15-30 em. high, 
which bifurcate above the middle. Indumentum usually spreading ; 
leaves setoso-tuberculate, linear, 2-3 mm. wide, with revolute margins, 
the uppermost broader (8 mm.) at the base, and sometimes semiamplexi- 
caul; the starry bristles (asterosetulæ), which are disposed in a circle 
round the base of the stronger bristle that crowns the tubercle, usually 
completely covering and concealing the surface of the leaf, thereby 
giving a grey aspect to the foliage in steco; fruiting calyces sessile ; 
corolla pale waxy yellow, 2-24 cm. long, puberulent, and with very 
minute scattered lemon-coloured glands: free part of filament equalling 
the length (c. 6 mm.) of the small anthers. — Nucules very small 
(c. 24 mm.). Habitat: the Apennines from southern Calabria to the 
Marches, reappearing near Trieste and in Istria. 
(B) var. dalmaticum mihiz 0. dalmaticim Seheele, in Flora, xxvi. p. 561 
= 0. Javorkw Simonk. quoad exempl. ex Dalmatia. This form seems 
to preponderate in Dalmatia. Scheele deseribed it from specimens 
collected by Petter near Spalato and distributed in 1830. It is very 
variable, but only differs from var. Column in the broader flattish 
leaves, hardly or not at all revolute at the margins, in the taller stems, 
and in the darker colour of the foliage in sicco, due to the more widely- 
spaced stellie allowing the leaf-surface to show between them. This 
variety is sometimes as hairy as var. Colummer, and more often much 
barer, in a form which I have called forma calvescens, especially in the 
Abruzzi and in Dalmatia. 
(C) var. veronense mihi = O. angustifolium of Rigo’s exsice. and of Fl. 
Ital. Exs. no. 939 (in synonymy), not of Lehmann. This has the
