Bentham described five species of Seguieria (Ann. Nat. Hist. 1: 479-480. Aug 1838; Trans. Linn. Soc. 18: 235. 1839) and mentioned the superficial similarity of this genus of Phytolaccaceae to Securidaca. Walpers (Walp. Repert. 1: 246-247. 1842), perhaps beguiled by Bentham’s interfamilial note, placed the five species in his enumeration of Securidaca, reproducing Bentham’s brief diagnoses and citing (as discovered by C. V. Morton) the wrong volume of the Annals. Bentham himself (Jour. Bot. Kew Misc. 2: 210. 1850) published a note on Walpers’ error. In the Flora of Peru [Field Mus. Publ. Bot. 13(pt. 3, no. 2): 911. 1949], Macbride gracefully evaded the problem of the correct binomial. This bibliographic error in Walpers’ compilation does not seem to preempt Bentham’s epithet in Securidaca. The general aspect (large leaves, small lateral inflorescences) of S. macrophylla is rather like that of S. froesii, but the completely glabrous leaves, ecristate keel, and glabrous fruit with the large corpus broad-winged on one side distinguish the earlier-described species. I have reservations as to the distinctness of S. cayennensis Blake and S. cristata A. C. Smith from S. macrophylla.
