REPORT ON THE BOTANY OF JUAN FERNANDEZ AND MASAFUERA 35 



There is a little uncertainty about this species, arising from the fact that Bcrtero 

 regarded the insular forms as belonging to Gunnera chilensis, Lam. (Gunnera scabra, 

 Ruiz et Pavon), and consequently distributed two species under the same number. A 

 specimen in Kew Herbarium without a number labelled ' : Juan Fernandez, Bertero," in 

 the handwriting of the late Sir William Hooker, agrees with Brown's brief description ; 

 but a female inflorescence and a seedling plant about eight inches high can hardly belong 

 to the same species. Bertero's label, bearing the number 1463, is attached to the same 

 sheet, and most likely the specimen figured for this work was sent with the latter as one 

 species, for Bertero (Annales des Sciences Naturelles, xxi. p. 348) says: "La tige du 

 Gunnera scabra acquiert dans ce lieu jusqu'a 10 pieds de haut ; ses feuilles varient con- 

 siderablernent : j'en ai vu de peltees, de tres-glabres, lisses, et meime luisantes." Bertero 

 named his specimens Gunnera scabra, var.foliis Iambus. Philippi describes the inflores- 

 cence of his Gunnera glabra thus: " Spica fceminea composita, rhachidibus partialibus 

 filiformibus. Flores masculi in pedunculi aderant ; an spica semper aut casu tantum 

 androg)ma V Yet his description of the leaf does quite well for Gunnera bracteata. The 

 stem, he states, is six feet high. Bertero cites the name " pangue," which belongs to 

 the continental Gunnera chilensis, for the insular plant. 



Gunnera peltata, Philippi.

The specimens in Kew Herbarium are too imperfect for satisfactory determination, 

 the base of the blade of the leaf beino- wanting; in all cases. There is no doubt that the 

 genuine Gunnera peltata is quite distinct from Gunnera chilensis, as it has a trunk from 

 twelve to eighteen feet high and distinctly peltate leaves. Among the specimens of 

 Gunnera in the Kew Herbarium is one sheet ticketed "Juan Fernandez, Douglas," which 

 seems to be the typical Gunnera chilensis ; the inflorescence and leaf corresponding exactly 

 to Chilian specimens. 



The genus Gunnera comprises about fifteen species inhabiting America, from Fuegia 

 and the Falkland Islands to Mexico, Abyssinia, Java, Tasmania, New Zealand, and the 

 Sandwich Islands.
