loo Alexander IV. Ez'atis, 



granulata, A. prehensilis, A. Spegaz:;iniana, A. spinulifcra, and A. 

 stolonifera Steph. (a species based on Australian specimens). 

 He does not include A. eriocaula, A. viuHifida, or A. pinnat'ifida. 

 With the exception of A. Negeri, Stephani's new species were all 

 based, either wholly or in part, on material collected by P. Dusen. 

 In 1900 and 1901 (28, 29) he published special papers on Dusen's 

 collections, in which the localities for these new species were given 

 in greater detail, and in these papers reinstated A. eriocaula and 

 A. piiinatifida as members of the Chilean flora. He likewise 

 included two species, A. fragilis and A. pulvinata, which seem to 

 be nothing more than nomina nuda and which therefore deserve 

 no further attention. In an independent paper on the vegetation 

 of Patagonia Dusen himself (7) described the habitats of some 

 of the species of Riccardia, which he had found, from an ecological 

 standpoint. 



In another paper, likewise published in 1901 (30). Stephani 

 listed the Hepaticae collected by Racovitza during the voyage of 

 the "Belgica" ; Aneura crispa, A. floribunda and A. spectabilis are 

 included. In a later paper, published in 1905 (31), he gave an 

 account of the hepatics collected by C. Skottsberg during the 

 Swedish South Polar Expedition of 1901-03. Among the four 

 species of Riccardia which he listed from Tierra del Fuego it is of 

 interest to note that he included A. multifida, a species which he 

 had excluded in 1899; the other three species were A. floribunda, 

 A. pinnatifida and A.4enax. 



A much more extensive paper (32) on the Hepaticae of south- 

 ern South America was published by Stephani in 191 1. It was 

 based on the large collections made mainly by Skottsberg during 

 the Swedish Expedition of 1907-09 to Patagonia and Tierra del 

 Fuego. In this paper nineteen Chilean species of Aiicura are 

 included, of which the following are described as new : A. cliileiisis, 

 A. crassicrispa, A. fuscobrunnea, A. profunda, A. spiniloba, 

 A. sitb nigra, and A. tenerriina. The remaining twelve species 

 need not be listed here, since all are found in Stephani's earlier 

 papers. In 1916 Skottsberg (22) described the ecological relation- 

 ships of many of the species he had collected. Stephani's last 

 paper dealing with Chilean Hepaticae (33) appeared in 191 7. The 

 new Aneura species of the Skottsberg collection were here rede- 

 scribed, and two other species, A. Lindaviana and A. nitdiinitra,
