ciently account for such slight differences as are now noticeable in the florulas 

 of the various islands. If we compare the florulas of these islands and the 

 Snares we find about seven species common to both the Snares and Long 

 Island . From the list of these — namely, Crassula moschata, Apium prostratum, 

 Myosotis albida, Veronica elliptica, Hierochloe redolens, Poa foliosa, and 

 Asplenium obtusatum — it will be seen that most of them are fairly widely 

 distributed over the southern islands. The characteristic species of the 

 Snares — viz., Stilbocarpa robusta, Anisotome acutifolia, Poa litorosa, and 

 Colobanthus muscoides—hsive not yet been reported from the Stewart Island 

 group, although some closely allied species are found among the latter. One 

 species, Senecio Stewartiae, is found only on the Snares, Solanders, and 

 Herekopere Islands. At present, therefore, it appears that the Snares 

 do not belong to the Stewart Botanical District, but rather to the Sub- 

 antarctic Province On the question of plant-distribution on these islands 

 L. Cockayne* and T. F. Cheesemanf have thrown much light in their 

 different papers dealing with the matter.
