The few widely distributed plants included comprise about 30 new 

 records for New Guinea, of which the most interesting are Xyris pauci/ora, 

 Bulbostylis capillaris var. trifida, Spathoglottis aurea, Polygonum strigosum, 

 Viola distans, and Hydrocotyle rotundifolia. 



Several of Beccari's Hatam plants have been re-collected, viz. Riedelia 

 orchioides, Palmeria arfakiana, in a J example, of which the ? is so far de- 

 scribed, Styphelia trochocarpoides,and Dicrotrichium brevipes. Of Gjellerup's 

 plants, as would be expected in working over the same ground, the dupli- 

 cate examples are more numerous, especially in the orchids, but even in 

 that order Smith has described 20 new species with four new varieties, and 

 in Ericaceae two Rhododendrons, four Vacciniums, and one Diplycosia prove 

 new, with one variety in Styphelia in Epacridacese. 



Collections made subsequently round Manokoeari (Dorei Bay) on some 

 of the islands along the coast, and at Humboldt Bay, have been separately 

 enumerated, no two species proving common to both the mountain and coast 

 flora. About 150 plants are comprised in this list, which includes one new 

 genus and several new species in ferns, with 27 new species in other genera, 

 and interesting new records, of which the larger portion is more Malayan in 

 type. Wide distribution of endemic plants is again a very marked feature. 



In working out these collections I must express my thanks to the expert 

 botanists who have so kindly determined those orders in which they were 

 interested. To Dr. J. J. Smith of Buitenzorg I am under especial obligation, 

 not only for undertaking the Orchidacese, Ericacese, and Epacridacese, but 

 also for many valuable details concerning work already done in the Arfak, 

 and in arranging for the services of one of his trained native collectors 

 who accompanied me to New Guinea. I am indebted to Dr. Odoardo Beccari 

 for working out the Palmse ; Dr. Valeton for the Ziugiberaceae and 

 Rubiacea? ; and M. Casimir de Candolle and Professor J. Macfarlane for the 

 Piperacere, Meliaceajj and the Nepenthacese. In London my thanks are due 

 to Drs. Stapf and Rendle and the staffs of Kew and the British Museum for 

 much kind help ; and in particular to Professor G. S. West for the deter- 

 mination of the Freshwater Algoe ; Miss A. Lorraiu Smith for the Lichens ; 

 Dr. A. B. Rendle for Pandanacese, Cyperacese, and Gramineje, and a new 

 genus in Urticacese ; Dr. 0. Stapf for Utriculariaceae and valued criticism ; 

 Messrs. J. Ramsbottom, A. Gepp, L. Hutchinson, E. G. Baker, H. N. Ridley, 

 and J. R. Drummond for Fungi, Bryophytes and Pteridophytes, Euphor- 

 biacese, Melastomacese, Moracea3, and Solanacese ; and to Mr. S. Moore for 

 the Labiata?, Acanthacese, and Composites, and his great kindness in revising 

 the proofs. 



The plants may be consulted at the British Museum, Kew, Leiden, and 

 Buitenzorg, and in my own collection (on loan to the British Museum).
