Acana smiguisor-bce, Vahl. B 



A. sanguisorbcs var. antarctica, var. nov. 



This is the common Accena of the Southern Islands, 

 and seems to me quite distinct from any form 

 found in New Zealand. It was most likely re- 

 ferred to var. pilosa by Kirk, to which form, or, 

 as I consider it, species, it bears some resem- 

 blance. The leaves are pale-green, but not 

 whitish -green as those of .4. sanguisorbce var. 

 pilosa, glabrous on upper surface, but with 

 many adpressed hairs on under-surface. Scape 

 almost glabrous, short and hardly raised above 

 the foliage, + 2-3 cm. long. (In the var. pilosa 

 the scapes are raised high above the foliage.) 

 Head ± 8-5 mm. in diameter ; calyx-lobes bright- 

 green (in the var. pilosa they are more or less 

 reddish), calyx-tube not densely pilose ; stamens 

 not exserted, but it may be that this variety is in 

 part dioecious. 



A. sanguisorbce antarctica can be distinguished 

 at a glance from A. saiigicisorbcB pilosa by the 

 general aspect, which is chiefly brought about 

 by the colour of the leaves, the length of the 

 scapes, the colour of the calyx-lobes, and the 

 length of the stamens. 



A. adscendens, Ysihl. C .. 



This is stated to occur in New Zealand, but Mac- 

 quarie Island specimens which I have examined 

 seem to me very difierent to the New Zealand 

 plant, with which I am well acquainted.
