ADDITIONS AND CORRECTIONS
- Page [5] and subsequent pages. For Ipomea read Ipomœa.
- Page [68.] For Hippomanes read Hippomane.
- Page [68.] For Conocarpus erecta read Conocarpus erectus.
- Page [122.] Sir W. Buller includes the fruits of the Puriri tree (Vitex littoralis, according to Kirk) amongst the food of the New Zealand fruit-pigeons.
- Page [177.] For Entata, in the head-line, read Entada.
- Page [266.] The fruits of Oncocarpus vitiensis have been found in the crop of a Fijian fruit-pigeon (Carpophaga latrans). See Hemsley’s Bot. Chall. Exped., Introd., 46, and iv. 308; also Newton’s Dictionary of Birds, p. 724.
- Page [368.] Sernander (p. 185) observes that the fruits of Naias marina have little or no floating power.
- Page [416.] For the first eight lines read as follows:—“Of these, 22 occur in Continental regions on both sides of the Pacific; 12 are found in the Old World alone; one is peculiarly American, and two are confined to the Australian and Polynesian regions. A few of these can be regarded as exclusively American in their origin, though the bulk of them hail evidently in the first place from the Old World. But from the circumstance that all or most of the other species of the genus concerned are confined to America, it may legitimately be inferred that Waltheria americana, Ageratum conyzoides, and Physalis angulata are American-born species. Teucrium inflatum is a peculiar instance of an American weed collected in Polynesia before apparently it had been recorded from the Old World.”
- Page [438.] For Conocarpus erecta read Conocarpus erectus.
- Page [417.] Add after Cardiospermum halicacabum.... “Its seeds, as my experiments show, possess little or no capacity for dispersal by currents, since they sink at once or within a few days, even after drying for months.”
- Page [455.] Omit the reference to figure 6 in the centre of the page.
- Page [498.] For Hippomanes read Hippomane.
- Page [508.] Amongst my Solomon Island collections identified at Kew were the fruits of a species of Litsea from the crop of a fruit-pigeon (Hemsley’s Bot. Chall. Exped., IV. 295.)
- Page [533.] For Commelyne read Commelina.
- Page [539.] At foot of page, for Thames sea-drift, read Thames seed-drift.
- Page [581.] For Crambe maritimum read Crambe maritima.
- Page [618.] Under Mascarene Islands add Myoporum to the plants linking them to the Pacific Islands.
OBSERVATIONS OF A NATURALIST
IN THE PACIFIC
CHAPTER I
INTRODUCTION
The study of insular floras.—Their investigation in this work from the standpoint of dispersal.—The significance of plant-distribution in the Pacific.—The problems connected with the mountain-flora of Hawaii.—The persistence of dispersing agencies at the coast, their partial suspension on the mountain-top, their more or less complete suspension in the forest, and the effect on the endemic character of plants.—The connection between the endemism of birds and plants.—The relative antiquity of plants of the coast, forest, and mountain-top.—The genetic relation between coast and inland species of the same genus.—The ethics of plant-dispersal.—Evolution takes no heed of modes of dispersal.—The seed-stage is the price of Adaptation.
