(DC.) Reiche. It is obvious that the existence of the binomial 

 Chabraea hdegrifoUa Phil. (1856), especially if invalid, does not pre- 

 vent the validity of a Lcvcherla intcgrifolia founded upon Philippi's 

 quite different Chabraea iniegrifolia of 1872. In the synonymy of 

 this species may be placed Leuceria Hahnii Franch. Miss. Sci. Cap. 

 Horn, V. 349, t. 3 (1889). L. fucgina Phil. Anal. Univ. Santiago, 

 Ixxxvii. 98 (1894). It is not improbable that this may also have been 

 the Chabraea suaveoleus, /3 iniegrifolia 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 is 

 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 is 

 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 paper 

 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. virens 

 (D. Don) Hook. & Arn.
