I received some time ago from my ever active friend the Barao do 
Castello de Paiva spec, of Centaurea maculosa Lam. Diet. i. 
669; DC. vi. 583; Koch 474; Jord. Obs. v. 61, t. 4. f. d; 
Gren. et Godr. ii. 254 ; RFG. xv. t. 48. ff. i., ii. ; C. jpanicu- 
lata Jacq. Austr. iv. 10, t. 320 (not Linn.), a common S. of 
Europe sp. with black-tipped pectinato-ciliate unarmed invol. 
scales (§ Acrolcyphus Cass.), which he supposed he had once 
met with on landing “ somewhere between S ta Cruz and Ma- 
cliico on his way to Can^al in June or July 1858 or 1859.”

some accidental mixture or confusion of spec.
