VASCULAR CRYI'TOGAMIA OF NEW GUINEA.

Dorset. Li N.W. Germany I know a few scattered bushes, which 

 I supposed to be B. argmtevs W. et N., and which resemble very 

 much the B. erythrinus. I believe there is no real difference 

 between this species and B. argenteus.

 me a few branches gathered by him near Lyme Regis, Dorset, 

 which agree exactly with the German plant.

14. R. gratus Focke. — Flowers and fruits very large ; pollen- 

 grains nearly all regular ; sepals patent after flowering or embracing 

 the young fruit. The Rev. E. F. Linton has sent me dry specimens 

 of this species, collected in Surrey, Norfolk, and Derbyshire.

VASCULAR CRYPTOGAMIA OF NEW GUINEA, 

 COLLECTED BY SIR W. MACGREGOR. 



By J. G. Baker, F.R.S. 



Baron von Mueller has sent to Kew a complete set of the 

 Vascular Cryptogamia collected by Sir W. Macgregor during big 

 recent adventurous expedition to the highlands of New Guinea, and 

 asked me to report fully upon them. The botanical results of the 

 expedition are of great interest. For a full account of the flower- 

 ing-plants obtained, reference must be made to a paper entitled 

 " Records of Observations of Sir Wdliam MacGregar's Highland 

 plants from New Guinea," read by Baron von Mueller, before the 

 Royal Society of Victoria, on the 12th of September, 1889, and 

 now published in their recently-instituted quarto Transactions. 

 Out of 61 flowering plants gathered in the mountain-zone, at 

 altitudes of between 8000 and 13,000 feet above sea-level, 38 

 species appear to be new and endemic. Two of these are new 

 genera, Ischnea, allied to Nananthea in Composite, and Decaloca in 

 Epacridacere ; of the other endemic species, 17 shew a northern 

 affinity. Amongst these are a Hypericum, a Sagina, a Rubus, a 

 Gentian, four Vacciniums and four Rhododendrons. Eleven 

 species, including a Phyllocladus, a Libocedrus, a Metrosideros, an 

 Olearia, and two Vittadinias, are allied to upland Australian and 

 New Zealand types. Fifteen species are conspecific with well- 

 known Australian and New Zealand plants, such as Myosotis 

 australis, Libertia pidchella, and Astelia alpina. There are four 

 Bornean plants, hitherto known only from Kina-balu. Cosmo- 

 politan temperate types are represented in the collection by Tarax- 

 acum officinale, Scirpus ccespitosus, .lira ccespitosa, and Festuca ovina. 

 There is a Himalayan Potentilla [leuconota D. Dou), which occurs 

 also on Kina-balu, and finally, it may be worth while to add, as I 

 have been asked about it several times, that " the Daisy " which
