548 ANNOTATIONES IN PIPERACEAS. 



In proceeding from Pau to Paris, I went out of my way to 

 pay a last visit to Dr. Dufour, at St. Sever. Here I remained 

 two days, and added the following interesting mosses to 

 my collection, viz. Tortula ambigua and cuneifolia, Funaria 

 Muhlenbergii and Hibernica ? Bryum Muelleri, MSS. (Br. pla- 

 tyloma, B. & S. non Schwgr.), and finely-fruited specimens 

 of Trichostomum subulatum, B. & S. I stayed ten days 

 in Paris, and from thence taking the route of Dieppe, I finally 

 landed at Brighton, on Good Friday, the 10th of April, along 

 with the treasures I had amassed, the latter all safe and in 

 excellent condition.

My dear Sir William, 



By desire of Dr. Miquel, I send you for your Journal the 

 following " Annotationes" upon some species of Pipe- 

 race<e, about which I wished to consult him. All Dr. Wight s 

 collection are comprehended among them, except apparently 

 one species, which Dr. Miquel has marked " Piper Nepalense, 

 perhaps, however, inadvertently. 



Yours faithfully,
