Dr. H. O. FORBES'S NEW GUINEA EUBIACEiE.— I. 



By H. F. Weknham, D.Sc, F.L.S. 



The plants described in the present paper, to be followed, it is 

 hoped, by othei-s covering the whole series, wei'e collected by Dr. H. O. 

 Forbes, F.li.Gr.S., in the years 1885-6. In 1885 an expedition was 

 organized, under this gentleman's leadership, with the object of 

 investigating the orography and natural history of the Owen Stanley 

 Kange, some twenty miles to the north-north-east of Port Moresby, 

 in British New Guinea. This range was named by the late Professor 

 Huxley, who had first sighted it from the deck of H.M.S. Huttlesnake 

 commanded by Captain Owen Stanlej^ as well as Mount Victoria — 

 originally named after Huxley by Dr. Forbes, the first to explore it. 

 The whole costly equipment for the expedition, Avhich was generously 

 subsidized by several learned societies, was lost, on the 26th of July, 

 1885, in the accidental wrecking of a lighter in the roads off Batavia. 

 Dr. Forbes refitted the expedition in Brisbane, and a fresh start was 

 made under the auspices of Sir Peter Scratchley, the new Governor 

 of New Guinea ; Port Moresby was reached on the 31st August, and 

 a substantial base-camp was established, and occupied on the 1st 

 October, in the region of Mount Sogere, at about 2000 feet above sea- 

 level and 25 miles from the coast. Owing to a host of adverse circum- 

 stances, prefaced by the disaster just described and culminating in 

 the death of Sir Peter Scratchley, Avho was more than favourably 

 disposed to the expedition, the latter proved a failure. After seven 

 months' occupation the camp, which had grown by then to the pro- 

 portions of a village and included the substantial beginnings of a 

 horticultural and botanical garden, had to be abandoned. The camp 

 was raided later by hostile natives, and the bulk of Dr. Forbes's 

 valuable collections was destroyed. The object of the present papers 

 is to furnish the names and descriptions of what is the mere residue of 

 a comprehensive collection of plants of the Sogere district. The t3'pes 

 of new species are preserved in the National Herbarium.
