Ditrichum ( THchostomim) sululatum, Bruch. — Mr. E. M. Holmes, 

 F.L.S., having been good enough to send me specimens in fruit of this 

 rare moss from a ne-^y locality, perhaps a few remarks upon it may not be 

 uninteresting. The (English) history of this moss is as follows : — It was 

 first discovered many years ago by the Rev. IVIr. Tozer, at Trethowell, 

 Dear Truro, in W. Cornwall, and, according to Wilson, a specimen was 

 sent to Prof. W. Arnott, named Didymodon pusillum operculo rostrato." 

 At the time when Wilson's ^'Bryologia" was published, this was tho 

 only British locality and specimen. More recently it was found by Mr. 

 Holmes sparingly at Bickley Vale, in S. Devon, but not at the time 

 recognised, owing to the capsules being old and without lid. The third 

 find was at Saltash, in E. Cornwall, by Mr. F. Brent, of Plymouth, and 

 on specimens being sent to IVIr. Holmes, he at once recognised it, the 

 plants being in good condition. Again it was found by I\Ir. P. V. Tellam, 

 at Sunny Corner, near Truro, in 1871 : possibly, but not certainly, the 

 original locality of Mr. Tozer. And lastly, JMr. Holmes has found it in 

 fruit, at Easter in the present year, at Tamerton Ffolliott, in S. Devon, 

 about four miles from the Cornish locality at Saltash : Bickley Yale is 

 about eight miles further east. There are thus two Cornish and two 

 Devon locahties. It seems at present to be confined in Britain entirely 

 to Watson's first province. Peninsula, sub-provinces 1 and 2 S. peninsula, 

 and ]\Iid-peninsula, and its comital distribution is 1, 2, 3, W. Cornwall, 

 E. Cornwall, and S. Devon. It differs from D. homomallum (some of 

 the smaller forms of which it resembles), in its time of fruiting — March 

 and April — the latter ripening its capsules in the autumn ; in its shorter 

 seta and shorter oval capsules, not ovate-oblong or elliptical, and in its 

 obhquely rostellate, not short and conical lid, and also by its old capsules 

 being usually a little bent to one side, and in its monoicous inflorescence. 

 It always grows in shady hollows, in hedgebanks, lanes, &c. , on yellowish
