A POINT IN NOMENCLATURE. 
By A. B. Renptz, D.Se., anp James Britren, F.L.S. 
Dr. Lrypav in the last issue of Engler’s Jahrbuch (xliii. 352), 
refuses to accept the name Physacanthus for a genus of Acan- 
Antes published by Bentham (Gen. PI. ii. 1085) in 1876, on the 
that the two gant nin ed by him as belonging to it 
wate tinksiown” (“unbekannt”); we presume Dr. Lindau means 
unnamed and undescribed. 
There is pa in the International Rules to support this 
view; on the contrary, the first example there Ent of the valid 
publication of a genus—Carphalea Juss. (Gen. Pl. 198, 1789)— 
corresponds in every respect with the publication of Physacanthus, 
the genus being established on an unnamed dried specimen col- 
lected by Commerson in Madagascar. 
r. Lindau prefers to retain his own name Haselhoffia, de- 
this was so teak pointed out by C. B. Clarke in Flor. Trop. Afr. v. 
57 (1899).
