value of Vallonea, which at one time varied between £20 and 
£25 per ton, fell to such an extent during the years before the war 
that export—from Patras, at any rate, had almost ceased, but 
during the war the price rose again. 
Lobel, loc. cit., fancied that he had seen the Vallonea oak in 
central Italy ; ‘ “hujus — observasse memini publica via qua 
itur Pesaro Romam.’’ His memory deceived him; he can only 
have seen the Turkey oak there (or possibly Q. pseudosuber), as 
is pointed out by the accurate Ray, Hist. i1. p. 1887 (1688), who 
knew that tree in Italy, whereas he had only seen the acorns of the 
Vallonea at Venice, imported from Vallona. 
he only spot in Ttaly where the Vallonea oak has any claim to 
be indigenous is near Tricase, in the extreme heel, where a fine 
group on the steep coast of the Adriatic has every appearance of 
being native, but as it is . isolated, one cannot feel sure that 
it was not planted of o 
XIV.—THE GENUS ROSMARINUS. 
W. B. Turrit. 
The genus Rosmarinus is limited to the Nisaieetiguent: Region, 
where it occurs in the southern parts of the European countries 
eid this sea, in North Africa and as far east as Cyprus, the 
Troad, and also Cilicia, according to Boissier, Flora Orientalis, 
vol. iv. p- 636. Most systematists have limited the genus to one 
species, namely, Rosmarinus officinalis, L., although about twelve 
plants have been given specific rank by various authors. The 
following revision of the genus is based mainly on the excellent 
material preserved in the ‘Kew Herbarium. 
Rosmarinus, L., Gen. Pl., ed. v. p. 14, n. 38 (1754); Benth. 
Gen. et Spec. Labiat. p- 314 ‘et in DC. Prod. vol. xii p- 360; 
Benth. et Hook. f., Gen. Plant., vol. i. p. 1197; Briquet in Engler 
u. Prantt, Pflanzenfam., 3A. p. 216. 
Rosmarinus officinalis, Z., Sp. Pl., ed. 1, p. 25 (1753); 
Briquet, Les Labiées des Alpes Maritimes, p- 179 (1891). 
This species is the common rosemary and 
may be subdivided as follows : — 
var. genuina, Turrill, var. nov. Frutex 
erectus, usque ad 6-10 dm. altus, =p 
longa, margine revolute, subtus 5 eta 
bracteae lanceolatae vel lanceolato-ovatae; 
pedicelli circiter 3 mm. longi. Calyx cam- 
tomentosus. Govolia: eirciter 1 em. St vel
