It is unfortunate, indeed, that this beautiful and unusual species — 
of the South Pacific islands cannot, for reasons of priority, bees 
tinue to be known by Willdenow’s well-chosen name.

The Acacia long known as A. linearis Sims, Bot. Mag. t. 156 
(June, 1820), must become A. longissima Wendl. Comm. Acac. 
45, t. 11 (Jan., 1820). The specific name linearis, therefore be- 
comes aveilabie, since it is no longer “ already borne by a valid 
species,” for the plant known as A. linifolia (Vent.) Willd, a — 
name over which the earlier one of Wendland must now take me 
cedence.

cated several of the more marked variants of this highly 
species. Although Bentham wrote, Fl. Austr. ii. 417 (1864), that 
these plants “ are connected by too many intermediate forms to be 
separable even as varieties’ they appear, after all, to be worthy 
a place in classification because they display, i

fagonioides is at once recognizable by the few small broadly obo- 
vate leaflets,

Bentham and subsequent authors have followed Link, L ey 
rejecting Robert Brown’s name because of the presence of Aca : 
ciliata Humb. & Bonpl. in Willd. Enum. Hort. Berol. 1055 (1809). 
But this latter name, as Bentham, Trans. Linn. Soc. Xxx. 0°. 
(1875), has shown, cannot be identified even approximately oe 


accord with Art. 51, 4 of the International Rules, in order to av" 
tg permanent source of confusion or error ”’ since — cel’ 
tification seems impossible.” This discardment, then, of A. oilic 
Humb. & Bonpl. makes it possible to take up the first pub! a
