Hepaticae : Yale Peruvian Expedition of ipii. 313 



V. Lophocolea Dumort. 

 13. Lophocolea diaphana Spruce 



Lophocolea diaphana Spruce, Hep. Amaz. et And. 426. 1884. 



On wet earth, San Miguel, 6,000 feet, July 24, 1911. 



The specimens are sterile and fragmentary, and their reference to 

 the present species is open to some doubt. L. diaphana was collected 

 by its author at several localities in Ecuador and was afterwards 

 distributed in his exsiccatae. In the set examined by the writer the 

 leaf-cells show minute trigones, although these are not mentioned 

 in Spruce's description. In the specimens from San Miguel there 

 are no trigones, but this might very well be owing to the poor develop- 

 ment of the plants. 



VI. Radula Dumort. 



14. Radula andicola Steph. 

 Radula andicola Steph. Hedwigia 23: 114. 1884. 



Radula viridi-aurea Spruce, Hep. Amaz. et And. 324. 1885. 



On rocks, San Miguel, 5,000 feet, September 2, 1911. 



A few fragments only but apparently referable to this species. 

 The plants are sterile except for the presence of discoid gemmae, 

 which are similar to those found in R. complanata (L.) Dumort. 

 R. andicola was based on three specimens, the first collected by Krause 

 in Ecuador, the second by Birschall in Venezuela, and the third by 

 Deventer in Brazil; the original material of R. viridi-aurea was collec- 

 ted by Spruce in Ecuador. In his recent synopsis of the genus Radula 

 Stephani^ reduces Spruce's species to synonymy, and ascribes a 

 still wider distribution to the plant, quoting it also from Cuba, Costa 

 Rica, Colombia, Peru, and Bolivia. 



15. Radula ramulina Tayl. 

 Radula ramulina Tayl. Jour. Bot. 5: 374. 1846. 



On rocks, San Miguel and vicinity, 5,000-6,000 feet, July 24 and 

 September 3, 1911. 



A large and conspicuous species, pale yellowish in color and growing 

 in depressed mats. The original material was collected by Jameson 

 in the province of Pichincha, Ecuador. Spruce collected it repeatedly 

 in the same country, and it has also been definitely reported from 

 Bolivia. Stephani gives no precise localities for the species but states 

 that it is abundant in the Andes.
