Anisotome. | UMBELLIFERAE. 673 
the “Genera Plantarum” Bentham transferred the whole of the species from 
Ligusticum to Actphylla, which course was shortly afterwards adopted by Cockayne. 
In my memoir on the “ Botany of the Subantarctic Islands,” published in 1909, I 
suggested (p. 408) “ that if it be considered necessary to limit Ligusticum to the species 
found in the Northern Hemisphere (and there is much to be said in favour of such a 
course), then it would be far more preferable to revive Hooker's genus Anisotome for 
the reception of the New Zealand species than to transfer them to Aciphylla, particu- 
larly as the habit of the true Aciphyllae, with their rigid and coriaceous spinous leaves, 
and paniculate inflorescence with spinous bracts, is most distinct, and certainly appears 
to justify their separation as a distinct genus, which would really be as well charac- 
terized as many genera of Umbelliferae accepted by most botanists.” Since then, on 
the initiative of Cockayne and Laing, most New Zealand botanists have accepted this 
view. The reconstituted genus Anisotome will therefore include 20 species from the New 
Zealand area, and possibly 2 others from Australia. It chiefly differs from Ligusticum 
+n the narrower fruit with the ribs often unequal in height, and in the fewer vittae.
