Fifty-eight natural orders, 147 genera, and 235 species, are included 

 in his enumeration, He mentions five new species — Viscum Lindsayi, 

 Celmisia Lindsayi, Poa Lindsayi, Aciphylla Colensoi, Crepis Novae 

 Zelandias, and exhibited drawings of them. There were also five 

 species which had not been previously found in Otago ; thirty were 

 rare in Otago or New Zealand, or exhibited other interesting peculi- 

 arities of geographical distribution ; twenty-five species were common 

 to New Zealand and Britain ; and twenty-seven were British plants 

 naturalized. Hardy immigrant plants are gradually displacing the 

 more delicate and rarer herbaceous natives of Otago and of New Zealand. 

 In the majority of cases it is to the detriment of the colonist whose 

 fields or pastures are destroyed by the luxuriant intruders, though in 

 certain exceptional cases, for instance, in the pasture grasses and 

 clovers, he is decidedly and largely benefited. 



Among the British plants which are naturalized, or are becoming 

 naturalized, near Otago, are the following : — Poa annua, Festuca 

 bromoides, Lolium perenne (rye grass), Anthoxanthum odoratum, 

 (sweet vernal grass), Holcus mollis, Phalaris canariensis (canary 

 grass), Alopecurus agrestis (a kind of fox-tail grass), Phleum pra- 

 tense (Timothy grass), Eumex acetosa, B. acetosella, B. crispus, 

 B. obtusifolius (various species of Docks), Stellaria media (chick- 

 weed), Cerastium glomeratum, C. viscosum, Spergula arvensis, 

 (spurrey), Brassica oleracea (cabbage), B. campestris (Swedish 

 turnip), Nasturtium officinale (water-cress), Capsella Bursa-Pastoris, 

 (shepherd's purse), Trifolium repens (white clover), T. pratense, 

 (red clover), Vicia sativa (common tares), Plantago lanceolata and 

 P. major (species of rib grass), Erodium cicutarium (stork's bill), 

 Urtica urens (nettle).

Mr. James M c Nab has made observations on some foreign Coni- 

 ferous plants raised from seeds ripened in Britain. He remarks : — 



" For some years past my attention has been directed to the Coniferaa 

 raised from seeds ripened in Britain, and I have now to make some obser- 

 vations relative to the few species which have come under my notice, 

 chiefly in the Edinburgh Botanic Garden. Beginning with Abies Doug- 

 lasii, I have examined specimens taken from the trees originally in-
