Paris, Ind. Ed. ii. 343, has several errors in his citation of this 

 species. 



Gymnostomum oranicum Kehm. 



The Hyinenostoma and their allies of South Africa are difficult to 

 grasp, and will probabty not be satisfactorily elucidated without an 

 examination of C. Mueller's types at Berlin. One misconception may 

 as well be cleared up, however. Eehmann issued No. 19, Musci 

 Austr.-Afr. as Gymnostomum oranicum. C. Mueller published this 

 in Hedwig. xxxviii. 112, as Weisia {Jlymenostominii) oranica Rehm., 

 but makes no reference in his description to the capsule orifice beyond 

 the terms " theca . . . microstoma . . . annulo nullo." 



On examination of Rehmann's No. 19, however (Bloemfontein, 

 Orange Free State), I find a peristome distinctly present. The 

 16 teeth are very minute, very little exserted above the capsule 

 mouth, and sometimes not at all, very narrow and pale ; but they are 

 regular, articulate, linear, smooth and hyaline. It is therefore a true 

 Weisia, not Hymenostomum. The dioicous inflorescence appears 

 to be the principal chamcter by which it can be separated from 

 W. viridula (L.). 



Ancectangium scabeum Broth. 

 Among some mosses collected by Wm. Leighton in 1917 on 

 Mt. Meru, German East Africa, at 5-6000 ft. altitude, sent to me 

 for determination by Mr. T. R. Sim of Maritzburg, were two gather- 

 ings of a minute Anoectangiuyn, one shorter and much more dense 

 and compact, but both belonging to the same species. They agreed 

 with the description of A. scabrtim Broth, precisely, and with an 

 original specimen of Hoist's gathering at Kew ; they also agree with 

 the description of A. 2ms ilium Mitt., with the sole exception that 

 Mitten (in Journ. Linn. Soc, Bot. xxii. 305) describes his species, 



collected by Bishop Hannington on Kilimanjaro, as ** nerve 



dorso laevi," and notes "a small species, which agrees very nearly 

 with A. Mariei, Besch., from Nossibe ; but the apices of the leaves 

 are wider and their nerve is not papillose."
