Pottia Wilsoni B. & S. 2. Growing plentifully in one place 

 near Windsworth on the coast to the east of Looe and running 

 into P. asperula with which it grows. Mr. Dixon wrote, " Your 

 Pottia is P. Wilsoni in very good condition," and after receiving 

 a fresh gathering, " The Pottia must be considered I think the 

 same as before — P. Wilsoni. In the former gathering I noticed 

 many capsules short and truncate as here, tending to suggest 

 P. asperula; but the leaves were octofarious. Here the 'asperula ' 

 form of capsule is in greater preponderance, but the leaves still 

 seem octofarious, and I think it must go as P. Wilsoni, emphasizing 

 what I have said as to the unsatisfactoriness of P. asperula as a 

 species," and afterwards he wrote about the latter gathering, 

 " I think that some bits of the Pottia about which I wrote 

 yesterday might be called P. asperula, having leaves less rosulate 

 and less octofarious and the short truncate capsules almost to 

 the exclusion of the longer ones. But evidently the two plants 

 run into one another." — P. asperula Mitt. 2. Growing sparingly 

 with P. Wilsoni as above. — P. Starkeana C. M. 1, 2. Perranporth 

 (B.) ; on clay sea cliffs at Portnadler, near Looe, Mr. Dixon wrote 

 about the Portnadler plant, " Some of it is certainly very small 

 but other plants here and there are much larger and more normal." 



Tortula aloides De Not. 2. Abundant on clay sea cliffs at 

 Portnadler and occurring elsewhere near Looe. — T.atrovirens Lindb. 

 3. Growing with and running into the following -.—T. atrovirens
