142 THE JOURNAL OF BOTANY 



block," contains two species, one of them similar to 0. rupestre, 

 but showing a very remarkable development of peristome, the 

 teeth being almost covered to "half their length with irregular 

 lumps of preperistome. The material is, however, too poor to 

 found a species upon ; but it may be hoped that the plant will be 

 rediscovered. 



AuLACOMiTRiUM. A scrap was sent for study, labelled in 

 Mitten's hand " Nilgiri, Beddome, 195 pt. c. Thyridiuvi Indicmn." 

 1 have compared this carefully with original specimens of Aula- 

 comitrium humillimum Mitt. (Japan ; leg. Maingay, det. Mitten, 

 Aug. 1891) at Kew, and the two plants are certainly identical. I 

 asked Mr. E. S. Williams to be kind enough to examine Mitten's 

 specimens of Thyridium indicum, to see if any trace of an Aula- 

 comitrium occurred there, but he replied : — " Under 195, Beddome, 

 I find a sterile plant named Thyridium indicum Mitt. MS., of 

 which there are three separate specimens, all alike, and no mixture 

 of any sort in the packet. It is very easy to believe, how^ever, as 

 you suggest, that so small a bit of moss, as is the specimen of 

 Aulacomitrium, might have been accidentally mixed with the 

 Thyridium, and really belong to a very different region." More- 

 over, the scrap so labelled appeared in every particular of condi- 

 tion identical with the type-specimens of A. humillimum, and I 

 think the conclusion is inevitable that it is a fragment of the Japa- 

 nese plant which had casually become placed with the Thyridium. 



Macromitrium Perrottetii C. M. Binsar, Almora, 1910 ; 

 leg. Miss E. Shepheard (no. 18), c. fr. Macr. squarrulosuvi C. M. 

 would appear to be nearly allied to M. Perrottetii, but I have not 

 been able to see an authentic specimen of the former. Mons. 

 Cardot writes that a specimen from the Nilghiris (leg. Perrottet), 

 so named by Bescherelle, does not agree with C. Mliller's descrip- 

 tion, in that the leaves are not spreading in the dry state, and 

 does not therefore appear to be correctly named ; it agrees with 

 Miss Shepheard's plant, and both only differ from M. Perrottetii 

 in having the leaves a little smaller, and the seta shorter. I have 

 examined M. Perrottetii at Kew, where it is well represented, and 

 shows considerable variation in size and length of seta, several 

 specimens being quite identical in these respects with the Binsar 

 plant, e. g. " No. 221, Herb. Ind. Or. Hook. & Thorns., Chongtoom, 

 ISikkim, 9000 ped., J. D. H." No. 239 in the sanie set (Nunklow, 

 Khasia, 5000 ped., H. & T.), it may be mentioned, is something 

 quite different, and incorrectly named. It is also perhaps worth 

 noting that the specimen of " M. squarrulosum MillL, Perrottet, 

 Neilgherries," in Herb. W. P. Schimper, at Kew, is certainly in- 

 correctly determined, being a species of quite a different affinity, 

 with leaves curled when dry. The distribution of M. Perrottetii 

 is from the Sikkim Himalaya to Ceylon.
