not been previously observed in New Zealand. It is a native of sandy shores in the south of Europe and north of Africa, but is now a common weed in many countries. Psoralea pinnata Linn. I am informed by Mr. H. Oakley that this has gone wild at Waipu, and threatens to become a serious nuisance. It is commonly cultivated in gardens, but I have not previously heard of its spreading spontaneously. Lactuca scariola Linn. Onehunga Railway-station yard; J. P. Kalaugher! Not previously recorded from New Zealand. Jasione montana Linn. Tutira Run, near the source of the Mohaka River, Hawke's Bay; H. Guthrie-Smith! This is the first recorded instance of this plant in New Zealand. Echium plantagineum Linn. Has been abundant on one farm at Kihikihi, Waikato, for more than forty years; J. B. Hayes! Has recently appeared in considerable quantity on the slopes of Mount Victoria, Devonport; J. P. Kalaugher I observed it in the vicinity of Auckland more than twenty years ago, but it seems to have died out in the original localities. Hyoscyamus niger Linn. Near Pakuranga, Auckland; R. Green! The only locality previously published for New Zealand is that of Wellington, by Mr. T. Kirk. Verbena bonariensis Linn. Near Kaitaia; H. Carse! Slopes of Mount Eden; F. Neve! Euphorbia segetalis Linn. On sand-dunes at Tauroa, near Ahipara; R. H. Matthews and H. Carse! Now recorded for the first time in the Southern Hemisphere. It is a native of southern Europe and north Africa, extending as far south as Madeira and the Canary Islands. Euphorbia cyparissias Linn. I am indebted to Mr. J. W. Murphy, of Christchurch, for specimens of this collected near Culverden, North Canterbury. As in the case of E. segetalis, it has not been previously recorded from the Southern Hemisphere. Alnus glutinosa Linn. Old trees of the alder have spontaneously appeared in not a few stations along the banks of the lower Waikato, from Huntly to within a few miles of the mouth of the river. Probably they have originated from seeds floated from Taupiri, where, I understand, it was planted by the missionaries prior to 1860. The willows which now form a continuous fringe along the banks of the river have doubtless originated from the same source. Eichhornia crassipes Schlecht. The well-known “water-hyacinth” has established itself in a lagoon at Te Aroha, according to information supplied to me by Mr. F. Neve. At
