Kirk.— On the Naturalized Plants of the Chatham Ids. 321 
amount of intercourse with other places, as already stated, has not afforded 
much scope for the introduction of many of those viatical plants which follow 
the footsteps of the traveller. These remarks are illustrated by Mr. Travers’ 
notes ; for instance, referring to Hypocheris 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, Rumex 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. 
Capsella bursa-pastoris, DC.—Amongst grass and in bush on both islands. 
Sinapis nigra, L.—Common about Waitangi. 
Silene anglica, L., b. quinquevulnera.—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, 7. K.) 
Trifolium minus, Sm.—Common amongst introduced grasses, 
Sherardia arvensis, L.—Only seen amongst cultivated grasses on Pitt Island. 
Bellis perennis, L.—Common in grass fields on main island ; not common on 
Pitt Island ; prefers clay land. 
Hypocheris radicata, L.—Only seen in grass fields in a few places on the main 
island 
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, Hoffm., 
which is certainly indigenous, 7.X.) 
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.
