226 v - Mueller, Notes on Botanical Collections. 



from Beccari's collection records the Q. Lamponga Miquel, also 

 from New Guinea in his extensive and elaborate work, „The Indo- 

 Malayan Species of Quercus," page 53, Plate 49. With this plant, 

 which he thinks reducible to Q. Pseudo-Molucca our Q. D'Albertisii 

 needs further comparison. Hybrids may also perhaps occur among 

 the many Oaks of Continental and insular India. Sir William Mac- 

 gregor sent further acorns of an Oak, fruits of which were also 

 brought from the Mount Obree Range by Sayer. Carpologically 

 il is related to Q. Reinwardti Korthaies, and Q. Cantleyana King, 

 but the foliage and flowers may prove very different. A third kind 

 of Papuan Oak is represented by acorns in the collection formed 

 at mount Dayman. The fruit bears similarity to that of Q. spicata 

 Smith, Q. cyclophora Endlicher, Q. pachyphylla Kurz. 



At the same locality were obtained. acorns of a species much 

 alike to those of Q. semiserrata Roxburgh and Q. Teysmanni Blume. 

 A fifth sort of Papuan Oak was received from the vicinity of 

 Mount Gilles, through M. W. Sayer. It is very different from 

 the other Papuan species hitherto known approaching closely 

 Q. Junghuhni Miquel ; but the leaves are nearly glabrous, much more 

 acuminate, and at the base less blunt; the fruits accord fairly well. 

 No material is available for ascertaining the charakteristics of wood, 

 bark and flowers. 



It may be of interest also to note hirn that Schuurmansia ele- 

 gans finally attains a height of 80 feet, that from the series of 

 forms betöre me it seems to constitute a monotypic genus, and that 

 this with its ally Sauvagesia has been justly transferred by Eng ler 

 from Violarinae to Ochnaceae. In a similar manner has by field. 

 researches in Java the genus Lepidostemon been declared unispecific 

 Such cases, moreover, demonstrate how difficult it still remains in 

 numerous instances to assign to Papuan plants the correct systematic 

 limitation in our present State of knowledge, necessarly imperfect from 

 insufficient material while the first explorations proceed. 



One of the most remarkable plants discovered on Mount Dayman 

 is a Carpodetus, C. Papuanus according to fruiting specimens ob- 

 tained. Of this genus on!y the typic species from New Zealand 

 C. serratus described by R. and G. Foster in 1776, Stands on 

 record. This demonstrates still further that forms of plants long 

 thought to belong exclusively to the most southern parts of the 

 world, constitute an appreciable immixture to the mountain flora 

 of New Guinea. The likewise saxifragous genus Quintinia has 

 been shown in my last report to occur likewise there ; but that is 

 represented also in Eastern Australia as well as in New Zealand. 

 Precisely the same can be said as regards geographic distribution. 

 Furthermore, Ackama is just traced to New Guinea as a genus new 

 for that area. Acaena and Azorella, now shown to be Papuan, 

 belong to the same category, but have a wider southern ränge. 

 Hypericum, Potentilla, Galium, Olearia, Styphelia, Gaultiera, Aga- 

 petes, Gahnia and Polytrichum occur also in the upper regions of 

 Mount Dayman, as they do on the Owen Stanley Ranges.
