cnspum, var. rostellatum, B.. & W., in Drummond's Southern Mosses 

 No. lo. Hab. New Orleans, Drummond.— I have not been able to 

 see Drummond's No. lo, but I have a Systegiuvi from the same re- 

 gion, collected by Hall, Mohr and Featherman, which appears to be 

 not rare throughout the Gulf region, and the only species yet found 

 there ; for the diagnosis of Bruch and Schimper describes it with 

 sufficient accuracy. It is Astomum {Sysfegtum) Ludovidanum, Sulliv, 

 Icones, T. i2._ The male flower is terminal, becoming lateral, as B. 

 & S. describe it ; or probably in rare instances becoming dichotomal 

 as shown in the Icones. 



(i6.) Orthotrichum brachytrichium, Schimp. ; O. obtusifoUum, 

 Drummond's Mosses of Brit. Amer., n. 157. Hab. Canada East to the 

 Kocky Mts— There is some mystery here which I am unable to 

 solve. Drummond's moss is identical with the European O, obtusi- 

 /o/ium,ScH^AD., which is most accurately described in Schimper's 

 Synopsis, Ed., i860, p. 263. It is also identical with the numerous 

 specimens which I have from the same region, collected chiefly by 

 l-owler and Macoun. Schimper describes it as having " apiculate 

 acutely carinate most minutely papillose leaves, with the margins 

 subrevolute-reflexed, inflorescence monoecious, calyptra pale straw- 

 colored and with a few short hairs on its apex." I find the leaves 

 to be obtuse, not carinate, mostly clothed with large papillae, inflo- 

 rescence dioecious, calyptra with a pale base, fuscous brown above, 

 epiiose, and papillose -tuberculate. I have picked from among some 

 Urf^o^. 0/iioense colltcted by myself in the JordansviUe Swamps,
