Kirk. — On the Naturalized Plants of the Chatham TJs. 321 



umount of inlorcoursc with otlier places, as alroady .stated, lias not aflbnied 

 inucli sco])C for tlie introduction of many of those viatical plants which follow 

 tlie footsteps of the traveller. These remarks are illustrated by Mr. Travers* 

 notes ; for instance, referring to Ilyjpochceris radicata, he writes, " Only found 

 in grass fields in a few localities on the main island," so that it is evidently of 

 very recent introduction, although within the past fifteen years it has become 

 a complete pest in cultivated and waste lands throughout the colony. Most 

 of the plants enumerated are said to occur either in * grass fields,' 'grassy 

 places,' or ' on abandoned cultivations;' only a single species, llumex acetosella, 

 is said to be generally distributed. All the species are of European origin, 

 with the exception of the prairie-grass, Bromus unioloides, which is American, 

 and, from its value as a nutritious grass adapted to a wide range of soil 

 and situation, is proving a welcome addition to our naturalized flora. 

 Ranunculus repens, L. — Old cultivations on main island. 

 Fumaria officinalis, L. — Grass fields on both islands. 

 Gapsella hursa-pastoris, DO. — Amongst grass and in bush on both islands. 

 Sinajjis nigra, L. — Common about Waitangi. 

 Silene awjlica, L., b. quinquevuhiera. — Seen only on Pitt Island ; amongst 



weeds and grasses on a newly made road. 

 Stellaria media, With. — Common amongst grass on both islands. 

 Cerastium viscosum, L. — Common amongst grass. 

 Geranium molle, L. — In grass, chiefly on Pitt Island. (There can be little 



doubt of this being indigenous, although its area has doubtless been 



extended by the progress of agriculture, 2\K.) 

 Trifolium minus, Sm. — Common amongst introduced grasses. 

 Bherardia arvensis, L. — Only seen amongst cultivated grasses on Pitt Island. 

 Bcllis perennis, L. — Common in grass fields on main island ; not common on 



Pitt Island ; prefers clay land. 

 Ilypochmris radicata, L. — Only seen in grass fields in a few places on the main 



island. 

 Sonchus oleraceus, L. — Common amongst grass in both parts of the island. 



(The specimens are too imperfect to allow of my determining the variety 



to which they belong, but I am inclined to refer them to S. asper, Hofim., 



which is certainly indigenous, T.K.^ 

 Anagallis arvensis, L. — Common in cultivations; especially on the banks of 



the great lagoon. 

 Solanum nigrum, L. — Common in cultivated ground ; said to have been 



brought by the natives from the main land. (Baron F. von Mueller 



considers this to be of recent introduction ; it was, however, collected in 



New Zealand by Banks and Solander.) 

 Prunella vulgaris, L. — Common on both islands; especially in water-courses.
