So closely allied to the common celery {Apium graveolens, Linn.) that it was 

 treated as a form of that species by Hooker (Fl. Antarct., ii, 287), although he sub- 

 sequently regarded it as distinct in the " Flora Novae Zealandiae." Wildemann, in 

 the recently published " Botany of the Voyage of the ' Belgica,' " has again re- 

 ferred it to A. graveolens (p. 134). It differs, however, as has been pointed out by 

 Bentham and other botanists, in the prostrate or decumbent habit, and especially 

 in the thick and prominent almost corky ribs of the fruit ; and I think it is best 

 kept as a distinct though closely allied species.

A noble species, excellently figured and described by Hooker in the " Flora 

 Antarctica." He remarks that " it attains a height of 6 ft., bearing several umbels 

 of rose-coloured or purplish flowers, each compound umbel as large as the human 

 head. The foliage is of a deep shining green, and the whole plant emits, when 

 bruised, an aromatic smell." 



In the " Genera Plantarum " Mr. Bentham referred to Aciphylla all the plants 

 from the Southern Hemisphere placed by Hooker in Ligusticum. No doubt he was 

 influenced by the fact that the floral and carpological characters of the two groups 

 are very similar. But, on the other hand, the habit of the true Aciphyllae, with 

 their rigid and coriaceous spinous leaves, and paniculate inflorescence with spinous 

 bracts, is most distinct, and to me certainly appears to justify their separation as 

 a distinct genus, which would really be as well characterized as many genera of 

 Umbelliferae accepted by most botanists. If it be necessary to limit Ligusticum to 

 the forms 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 southern species than to transfer them to Aciphylla.

Almost as striking a plant as the preceding, from which it is easily distinguished 

 by the finely divided leaves with numerous linear segments.
