(DC.) Reiche. It is obvious that the existence of the binomial 
Chabraea integrifolia Phil. (1856), especially if invalid, does not pre- 
vent the validity of a Leucheria integrifolia founded upon Philippi’s 
quite different Chabraca integrifolia of 1872. In the synonymy of 
this species may be placed Leuceria Hahnii Franch. Miss. Sci. Cap. 
Horn, v. 349, t. 3 (1889). L. fuegina Phil. Anal. Univ. Santiago, 
Ixxxvii. 98 (1894). It is not improbable that this may also have been 
the Chabraea suaveolens, 8 integrifolia Sch. Bip. Flora, xxxviii. 121 
(1855), nomen nudum.

Perezia virENs (D. Don) Hook. & Arn. Comp. Bot. Mag. i. 34 
(1835). This species is referred by Reiche, Fl. Chil. iv. 445 (1905) to 
P. Poeppigii Less. Syn. Comp. 411 (1832). It is clear that the 
validity of P. virens must depend upon the date of its name-bringing 
synonym Clarionea virens D. Don, Trans. Linn. Soc. xvi. 208. It 1s 
true that the volume in which it was published bears the date 1833, 
but it is stated that Don’s paper was read 1829 and there is every 
reason to suppose that the different papers of which the volume 15 
composed were issued as printed and at quite different dates. Fortu~ 
nately there is conclusive proof that Don’s paper had reached print 
and issue before Lessing’s publication, for Lessing cites Don’s papet 
on pages 407, 408, 412, and elsewhere in his Synopsis, which should 
settle the matter of priority and lead to the re-instating of P. wrens
