MISCELLANEA BRTOLOGTCA 77 



^ith, is autoicous ; the leaves are considerably wider than in. S. lam- 

 prophyllu^n, the alar cells are quite different, not indeed showing the 

 characteristic inflated cells of Sematophyllum^ usually consisting of a 

 single large inflated cell and several much smaller irregular thick- 

 walled ones. The upper cells show regularly seriate, fine, acute 

 papillae ; the perichsetial bracts also are markedly papillose. In view 

 of the character of the alar cells, and the seriate papillae of the upper 

 ones, I have little doubt that the plant is not a Sematophyllum, but 

 a Trichosteleum. 



The fruit of the true S. lampropJiyllum is to be seen on the plant 

 issued by Max Fleischer as Pungentella scahrella (Lac.) C. M., 

 No. 389, Musci Frond. Archip. Ind. Ser. viii. from West Java. This 

 agrees in habit, leaf-form, and basal cells with the H. scahrellum. 

 The perichsetial leaves are comparatively short, erect, rigid, finely but 

 shortly subulate, practically entire, and smooth. Seta about 1 cm., 

 scaberulous above. No male flowers appear, the plant is undoubtedly 

 dioicous. No. 5417, Perak, coll. Wray, in Herb. Mus. Brit., also 

 appears to be the correct plant. 



In Journ. Linn. Soc, Bot. xliii. 321, I referred to S. lampro- 

 pTiyllum (Mitt.), a plant of Rev. C. H. Binstead's from Borneo, 

 Avhich, however, I find must also be considered distinct, as the fruiting 

 characters do not agree with those of Fleischer's No. 389. Especially 

 it is autoicous, and the perichsetial bracts are sharply and rather 

 closely denticulate. It appears to be undescribed, and may be diag- 

 noted as follows : — 



Sematophyllum decipiens Dixon, sp. no v. Habitu ;S'. lampro- 

 pJiylli Mitt., sed paullo robustius, foliis latioribus, ovato-lanceolatis, 

 concavis, marginibus erectis, acumine breviuscule subulato, denticu- 

 lato. Autoicum. Flores masculi, numerosi, parvi. Bractese peri- 

 chsetiales magis abrupte angustius acuminatae, sat conferte denticulatae, 

 dorso sublaeves. Seta perbrevis, circa 5 mm. longa, capillaris, laevis ; 

 theca minuta, '75 mm. longa, horizontalis. 



Hah. Damp rock in jungle, Sapong, near Tenom (No. 211 5). 



The autoicous inflorescence removes it from the otherwise nearly 

 allied species ; the denticulate perichaetial bracts also from >S'. lampro- 

 phyllum ; the wider leaves from S. suhulatum (Hampe) ; the smooth 

 seta, scaberulous cells and larger capsule from S. microthecium Broth. 

 & Paris. 



Cetlonese Mosses. 



Two or three corrections need to be made in my paper in Journ. 

 Bot. 1915, 257, on the Rev. C. H. Binstead's Ceylon mosses. 



P. 259. — Dicranoloma leucophyllum (Hampe) Par. var. Kurzii 

 Fleisch. appears to be rather a varietal form of D. hrevisetum (Doz. 

 & Molk.) Par. 



P. 289.— Trachyloma indicum Mitt. This agrees quite well with 

 a New Guinea specimen determined by Mitten as his species. 

 Fleischer has, however, pointed out that this species has been con- 

 fused with T. tahitense Besch., a closely allied species with less 

 glossy, shorter pointed leaves and quite distinct areolation. To this 

 latter he refers Ceylonese specimens collected by himself ; and I find
