leaves, as in Pirea cymhifolia. Dr. Small and Mr. Carter also collected it in 

 Andros Island, Bahamas, in 1910, and in hummocks at Grassy Key in subtropi- 

 cal Florida, January 1909. Mr. Williams found abundant and well-grown 

 material at Cana, Panama, in 1908, also sterile. It occurs also in Porto Rico, 

 near Mayaguez, and I have collected it growing on twigs and bushes near Guana- 

 bana in the Trinidad Mountains of Santa Clara in Cuba. It appears to be 

 dioicous as these last were archegonial plants. 



For many years I have wondered what Neckera {Pilotrichum?) floridana 

 Aust. was, for all the specimens in Austin's Herbarium agree with Pirea Ludo- 



Leucodoniopsis Floridana.

viciae (C. M.) Broth. At last I have seen authentic specimens, collected on 

 trees, near Dr. Kellum's on the Caloosahatchie River, near Caloosa, Florida, by 

 John Donnell Smith and Coe Finch Austin in March, 1878, and to my great 

 surprise, they prove to be identical with Leucodoniopsis plicata R. & C. The 

 description in Lesquereux and James' Manual is a translation from Austin's in 

 the Botanical Gazette and evidently they had seen no specimens, for the ques- 

 tion mark after {Pilotrichum?) was printed as Austin had it and this species 

 evidently has no alliance with that genus, which has bicostate leaves and belongs 

 with the Hookeriacece! 



Austin added the following foot-note to the original description: 

 "Leaves usually with a plica near the margin at the base, or often extend- 

 ing to near the apex; costa very light and usually extending a little way above 

 the middle. Possibly a Meteorium. "
