The following minor differences appear to exist between the New 

 Zealand and Tasmanian forms : In G. cordifolia the petioles are shorter 

 than the lamina, in G. densiflora (?) they are longer. The blade in the 

 Tasmanian plant is more triangular and less rounded than in the New 

 Zealand one, much more hairy on the margin, and the stolons have much 

 shorter internodes. The male spikes of the one seem, however, to agree 

 well with those of the other, and the general resemblance is undoubted. 

 It will, however, be better to regard our plant as distinct until better 

 evidence of identity is obtained. 



Mr. Cheeseman informs me that my plant is distinct from that collected 

 by Dr. Cockayne on the Craigieburn Mountains, and identified by the 

 Kew authorities as G. densiflora Hook. f. I have, unfortunately, seen no 

 specimens of Dr. Cockayne's plant. 



I have deposited a specimen in the Canterbury Museum. 



2. Anisotome Enysii (T. Kirk) Laing (comb. nov.). 



Cockayne and Laing (he. cit.) have restored the genus Anisotome for 

 the southern species of Ligusticum ; hence the necessity for this alteration, 

 and the following. 



3. Anisotome Enysii (T. Kirk) Laing (comb, nov.) var. tennysonianum 



Laing. 



Foliis pinnatis, ambitu deltoideo-ovatis, pinnis inferioribus trifoliolatis, 

 foliolis minus argute dentatis minus crassisque, quam in forma typica, 

 latioribus autem rotundioribusque. 



I have hesitated whether to describe this plant as a fresh species or 

 only as a variety of A. Enysii. I have adopted the latter course, because 

 on examining specimens of A. Enysii from Central Otago and Banks 

 Peninsula I find that they differ considerably, and probably contain more 

 than one elementary species. Further, I have not seen any type specimens 

 of A. Enysii from Castle Hill, and consequently cannot be sure that any 

 of my species truly represent the original type. Until, therefore, the limits 

 of the species A. Ensyii are better defined it will perhaps be safer to 

 include this under it as a variety. 



A. Ensyii from the Lyttelton Hills is a dwarf chasmophyte with minute 

 linear involucral bracts, united only at the base, and with well-marked 

 ridges on the fruit. A second form is found growing in the turf on the 

 Akaroa - Flea Bay ridge ; the pinnae are more distant, the whole plant is 

 taller and laxer than the Lyttelton one, and the involucral bracts are 

 usually free. 



In the plants from Naseby given me by Dr. Petrie the toothing of the ' 

 leaves is less sharp and less deep than in the other forms, and the terminal 

 segment is broader and rounder, whilst the involucral bracts are usually 

 sheathing, as described by Cheeseman. When such differences as these 

 exist in the forms already grouped under A. Enysii it seemed unwise to 

 make a fresh species of this plant, particularly as it was found in only one 

 locality, in the upper river steppe on the western side of Lake Tennyson. 

 Though differing markedly from A. Enysii in the form of the leaf, the 

 floral characters present only slight variations. A fuller description is 

 appended.
