etc. One of the very few naturalized plants found on the Little Barrier 



Island. 

 Arenaria serpyllifolia, L., Europe, A., 3. Unc. Col. Lit. Local. Confined to a 



solitary locality on the sandy beach at Koheroa, near Omaha, possibly a 



waif brought hj the sea. 

 Sagina apetala, L., Eiirope, A., 3. Unc. Ali. Via. Only observed in a single 



locality, into which it has been latterly destroyed by traffic. 

 Cerastium vulgatum, L., Europe, A., 1-2-3-4-5-6. Ace. Den. (?) Col. (?) Pas. 



Via. This and a few other species require a term somewhat intermediate 



between "Denizen" and "Colonist," being sufficiently abundant and 



general to belong to the former, while their small size prevents their 



interference with the original vegetation, to any marked extent. 

 Cerastium viscosum, L., Europe, A, 1-2-3-4-5-6. Ace. Den. (?) Col. (?) Pas. 



Via. Pup. Observed at an altitude of 2000 feet. 

 Polycarpon tetraphyllum, L., Europe, A., 1-3-4-6. Ace. Den. (?) Col. (?) 



Lit. Via. 

 Spergula arvensis, L., Europe, A., 1-2-3-4. Ace. Col. Agre. 



PORTULACE^E. 



Portulaca oleracea, L., Europe, 1-2-3-4. Hor. (?) Ace. Den. Lit. Agre. 

 Often forming a compact sward in the immediate vicinity of the sea. A 

 troublesome weed in rich cultivated land. 



Hypericine^e. 



Hypericum Androscemum, L., Europe, P., 6. Hor. Col. Via. Local. 



,, perforatum, L., Europe, P., 4-6. Ace. Den. Pas. Local but 



abundant. 

 Hypericum humifusum, L., Eui'ope, P., 3. Ace. Col. Pas. Local. 



Malvaceae. 



Malva sylvestris, L., Europe, A., 6. Ace. Col. Pas. Local. This and the 

 next species appear to be annual in N. Z., although biennial or perennial 

 in the northern hemisphere. 



Malva rotivndifolia , L., Europe, A., 2-3-4-5-6. Ace. Den. Agre. Via. 

 ,, caroliniana, Yi., 1ST. America, P., 1-2-3-4-5-6. Ace. Den. Via. 



Lavatera arborea, L., Europe, P., 3-4-6. Hor. Col. Lit. Via. 



Line^:. 

 Linum zisitatissimum, L., Europe, A., 2-3-4. Agri. Ace. Col. Agre. Via. 



Geraniace^e. 



Geranium molle, L. Included in the list of naturalized plants given in the 

 "Handbook," but should, I think, be considered indigenous, although its 

 area may have been widened by introduction. 



Pelargonium quercifolium, Alt., Cape of Good Hope. P., 2-3-6. Hor. 

 Col. Via., etc. 



Erodmm cicutarium, L., Europe, A. (?), b. clmrophyllum, v. " littorale" 

 1-2-3-4-5-6. Ace. Den. Via. Found also in Marlborough, (Buchanan.) 

 A remarkably variable plant ; the leaflets in the typical are sometimes 

 scarcely toothed and very broad, and in var. b. narrow-linear, closely 

 resembling the garden Chervil, var. v. has almost entire leaves, more 

 resembling E. maritimum, Sen., than the present species. It is confined 

 to the Bay of Islands. 



Erodium moschatum, Sm. Europe, A., 2. Ace. Col. Via. Local. Perhaps a 

 form of the preceding species.
