The phanerogamic flora of the New Hebrides and its relationships

The phanerogamic flora of the New Hebrides is mainly of the Malesian type both in floristic composition and structure of the vegetation. It is however a depauperate sample with fewer families and genera, most of which have a high proportion of elements with very wide geographical ranges of distribution. Most of the species have also been observed to have great ecological amplitude. At the level of family and genus, there is a total absence of endemic and relic elements; and only at the species level is there an appreciable degree of endemism. Unlike the Solomon Islands, the New Hebrides flora does show some regional differentiation. The northern islands appear to differ from the southern islands not only in frequencies of occurrence of species but also in the actual presence/absence of many significant groups. The flora of the New Hebrides has been found to have closer affinities with those of Fiji, Samoa and Tonga to the east than to islands to the west and northwest, despite the fact that the New Hebrides are closer geographically to the Solomon Islands and New Caledonia. It is suggested that the New Hebrides have a very young immigrant flora and that the colonization of the archipelago has taken place very rapidly in very recent times. It is also maintained that plant dispersal to the islands has been trans-marine rather than by migration over land.

SummaryIn view of the discovery of several new species and subspecies of Amblypelta (Hemiptera, COREIDAE), some of which are either known to be or else threaten to become of economic importance, a revision of the whole genus has become necessary.The genus Amblypelta, as defined in the present paper and as known so far, is confined to Australia north of Sydney, the islands between Australia and New Guinea, New Guinea and, to the west, the Kai Is., Timor and Java; the Bismarck Archipelago, the Solomon Islands including Bougainville, Eennell and Bellona; the New Hebrides and New Caledonia. In the present revision of the genus, twelve species and five subspecies are included, of which all but seven species are new to science. Apart from the descriptions of the new species and subspecies, taxonomic notes on the previously known species are given as well as a key to all the species.The known distribution of each species is stated, and consideration given to the zoogeography of the genus as a whole, and of certain species-groups which can be recognised within the genus.

The spots are at first small, oval, brown; enlarging and becoming pale buff in the centre with a broad, dark brown margin. In severe attacks the edges of leaves become extensively necrotic. GEOGRAPHICAL DISTRIBUTION: Apart from records from Jamaica and Seychelles the fungus has been reported only from S.E. Asia, Australasia and Oceania: British Solomon Islands, Fiji, French Polynesia, Malaysia (W., Sabah, Sarawak), New Caledonia, New Hebrides, Papua-New Guinea, Philippines, Sri Lanka, Vietnam and Thailand. TRANSMISSION: Presumably air dispersed.
