Maichantiaceae. 



Lunularia [Mich.] Adans. 



*3. L. criiciata (L.) Duniort. Comm. Bot. 116(1822). — Syn. JllaichaJiiia 

 cniciata L. Sp. Pi. 1137 (i753)- Several other synonyms might be cited. 

 Earth, roci<s and decayed logs, mostly below 500 m. 



Masatierra: Q. Juanango, on ground in forest, 250 m. (no. 8). 



Masafuera: Q. de las Casas, on rock wall (no. 9), at entrance (no. 9 a), 

 and in the outer part (no. 10); same locality, Skottsberg, 1908 (no. 11); Q. 

 de la Loberia, forest soil, 280 m. (no. 12); high ridge between Sanchez and 

 Token, on the ground and on decayed logs, 515 m. (no. 13). 



As noted obove L. cruciata occurred in Skottsberg's earlier collection 

 but is here recorded from Juan Fernandez for the first time. The earlier spe- 

 cimens were mixed with Marchantia foliacea. Probable all writers at the present 

 time regard the genus Lunularia as monotypic. 



Area of distribution: Mediterranean region of Europe, Africa and Asia; 

 Australia, Chile and Juan Fernandez; present also in many other parts of the 

 world but usually appearing as if introduced and confined to greenhouses in 

 cold climates; absent from most tropical districts.

 originally cited from Juan Fernandez by MoNTAGNE, 308, no definite locality

Area of distribution: almost cosmopolitan but especially abundant in 

 northern regions; becoming rarer southward and sporadic in the tropics, often 

 appearing introduced; in South Temperate and Antarctic regions now known 

 from Chile, Kerguelen Island, the Crozet Islands, South Georgia and New Zea- 

 land, as well as from Juan Fernandez.
