strophiola conspicua cerina medio perforata, marginibus in annulum ob-

In this plant the racemes are frequently so abbreviated that the 
purplish-pink flowers arise at the same level from the clavate or globu- 
Jar node-like termination of the branch, a mode of inflorescence pre- 
cisely similar, though on a smaller scale, to that of Canavalia. When 
this character and that of the presence of s/ipelle, before indicated by 
me, are taken into consideration, it will, I think, be admitted that 
Abrus would be better removed from Viciee, where Mr. Bentham has 
placed it in the ‘ Genera,’ to Phaseolee, with which it was associated by 
De Candolle, and Wight and Arnott. Æ. Cantoniensis differs from its 
congeners by the conspicuously strophiolate seeds; but that this cha- 
racter is only of secondary importance, may be inferred from the fact that 
Rhynchosia, another Phaseoleous genus, includes species some of which 
have seeds with a caruncula, whilst others are destitute of that appen- 
dage. 
AIRA ULIGINOSA, Weihe. 
Erratum, p. 281.— By an awkward inadvertence on my part, the 
name of Aira flexuosa was written for the head-title of my communica- 
tion about 4. uliginosa. As the two specific names are rightly applied 
in the general text, and even the right authority given for the name in 
the head-title (Weihe, not Linn.), a botanical reader will easily infer 
that “flexuosa” was simply an error of the pen.
