Botany of Juan Fernandez and Easter Island.*—<A recently 
published report on the collections made by Dr. and Mrs. Skotts- 
berg during the Swedish Expedition to Patagonia and Terra del 
Fuego in 1916 and 1917 contains three papers dealing respectively 
with (1) the Pteridophyta of the Juan Fernandez Islands; (2) the 
Ferns of Easter Island; and (3) the Myxomycetes of Juan 
Fernandez. The two first are by C. Christensen and C. Skottsberg, 
and the last by R. E. Fries. Up to 1908, 42 species had been 
recorded from Juan Fernandez, while the number now known is 
51, of which 17 are endemic, and 2 species, known elsewhere, are 
represented by endemic varieties. One genus, T'hyrsopteris, is 
endemic and does not occur at altitudes below 400 metres; for 
an account of this plant see Kew Bulletin, 1915, p. 295. Of 
the species recorded outside Juan Fernandez, 27 are also found 
on the continent of South America, 5 in tropical America, 6 in 
‘the Falkland Islands, 5 in New Zealand, and 5 on the“Australian 
continent. Three others occur on islands in the southern 
ocean.” Three are of wide distribution, viz.: — Cystopteris 
fragilis, Bernh., almost cosmopolitan; Polypodiwm lanceolatum, 
L., throughout the tropics, and Elaphoglossum Lindenii,' T. Moore, 
tropical America. Some species also found in the Falkland 
Islands sebanie a high altitude in Juan Fernandez, two being 
found up to 1,370 metres, while Serpyllopsis caespitosa, C. Chr., 
and Adiantum chilense, Kaulf., extend up to 1,400 metres, the 
last named also going down to sea level. 
Easter Island was visited in June, 1917, when all the ferns 
previously recorded were again collected as well as five additional 
ones, bringing the total for the island up to 12. Two are 
endemic; one of these, Dryopteris Espinosai, Hicken, had 
previously been collected by Mr. F. Fuentes; the other 
proved to be a new oe eee Doodia paschalis, allied to the 
Australian D. blechnoides, A. Cunn. Most of the other species 
have a wide tieibGtion. and are of a more tropical type than 
those from Juan Fernandez, though the latter is only about 
5° further south. 
hirteen genera of M yxomycetes, comprising 18 species, are 
enumerated Pans uan Fernandez by Dr. R. E. Fries. None 0 
these is endemi 
The report is a ildeveaded by 5 ites and several text figures.
