300 NOTE ON HYPERICUM UNDULATUM. 
to note liow well tlie species was understood two years previously by 
the late venerable Prof. Treviranus, an excellent botanist, who possessed 
a profound critical knowledge of the European Flora. At page 9 of 
his work, ' In Hyperici Genus ej usque Species Animadversiones,' pub- 
lished towards the close of 1861, I find the following words : — ■' Hy- 
pericum qnadrawgnlum, E., in jus specie! restituatur, et erit itaque //. 
undulatum, Schousb. Flores magnitudine illis H. tetrapteri accedunt. 
Ab is to tamen non licet separare H. JBaticum, Boiss.,* quoad specimina

his c Sylloge/ placed 1L Neapolitamm, Ten., as a synonym of //. 
tetraptenwi, its identity with II. undulatnm, was pointed out twenty- 
three years ago by Gussone (Flor. Sic. Synops. ii. 379), from the ex- 
amination of De Candolle's herbarium. I am not aware on what 
grounds Prof. Babington (to whose paper in the first volume of the 
Trans. Bot. Soc. Edinb. I have not access) and Mr. Bentham apply 
the name of II. quadranguhm to H. tetrapterum, in opposition to the 
opinion of Fries, Spaeh, Koch, Godron, Fenzl, and Treviranus. Fries 
distinctly states (Nov. Fl. Suec. ed. alt. p. 236), that he himself first 
gathered it in 1819 in Sweden, where it only occurs in the province ol 
Scania ; and moreover, irrespective of other arguments, Linmvus's de- 
scription agrees better with the H. dubium of Leers. (Compare 
writes
