this memoir, in watching the Epilobia for many years in Australia, 

 is persuaded, that no other but this species occurs in this continent, 

 where it is widely dispersed over the extratropical part, reaching 

 tropical latitudes towards the east coast, ascending to the summits 

 of the alps and penetrating to the edges of the arid deserts. 

 Adapting itself to so varied climatic conditions the plant assumes 

 corresponding protean forms, though, as remarked, apparently not 

 those forms which in the humid climate of New Zealand have their 

 prototype in E. rotundifolium. Some of the extreme varieties of the 

 species appear to the isolated observer to indicate specific distinction ; 

 but it would be a vain attempt to draw the limits between these 

 forms, as no diagnosis founded on them would stand the iield-test. 

 Through the kindness of W. Woolls, Esq., of Parramatta, I received 

 specimina, collected by All. Cunningham at the Bay of Islands in 

 July 1838, and to which Cunningham attached the name E. rotun- 

 difolium, thus apparently discarding the distinctions on which his 

 E. nummularifolium, &c., rested ; for these specimina accord more 

 closely with Dr. Hooker's definition of E. nummularifolium than 

 with that of E. rotundifolium. The copious production of seeds of 

 all Epilobia renders it unlikely, that specific demarcations between 

 them have been obliterated by hj'bridism. It is a curious fact that 

 seemingly hitherto no other Epilobia have been found in the southern 

 hemisphere than those referable to E. tetragonum.

Common in the woods of Chatham-Island. 



A stately plant, dwarf when growing on the sea^coast. Leaves 

 lanceolate-ovate or lanceolate, without conspicuous stipules. Brac- 

 teoles at the base of the pedicels canalicular-lanceolate, ^-1'" long. 

 Teeth of the calyx 5, occasionally 6 or 7, deltoid, about f'long. 

 Petals semilanceolate, with broad base sessile, 2-2^'" long, inside 

 yellow, tardily dropping. Stamens inserted outside of the narrow 

 epigynous disk. Anthers yellow, ellipsoid, dorsifixed, hardly 1"' 

 long. Ovary two-celled, each cell containing a single pendent ovule. 

 Fruit a true drupe, with orange-colored pericarp. Putamen egg- 

 shaped, thick, bony, one-celled. Seed about 2"' long, ellipsoid- 

 cylindrical. Testa tender-membranous, pallid. Embryo equally
