C. inchangae (C. M.) Par. Buccleuch, 4000 ft., Natal, 1912 ; coll. Sim 
(No. 8544) c. fr. ; Kaapsche Hoop, Transvaal, coll. H. A. W. (Nos. 209, 300) 
c. fr. ; Montagu Pass, CP. ; coll. H. A. W. (No. 567p.p.). 
Sim's plant agrees exactly with Rehmann, M. Austr.-Afr. 42. Wager's 
plants are a little smaller, but agree structurally. The fruiting plant is,, 
as often, rather less robust than the sterile ones. C. Mueller's description 
(Hedwig. 38, p. 83) is decidedly misleading ; the description of the stem- 
leaves as " minuta " is absurd, while that of the lamina as " summitate 
denticulato-abruptam " is C[uite inaccurate, as the subula (in Rehmann's 
plant) is sharply denticulate for some way down, both on the back and 
the margins. The perichaetia are aggregate, the capsules rather large, the 
calyptra deeply fringed at base. 
The species appears to be a highly variable one ; the nerve varies greatly 
in width from one-third to three-fifths of the width of the leaf, or more ; 
the subula may be rather short and stout or longly filiform, especially in 
the floral leaves, while the auricles, always well developed and generally of 
a beautiful orange-brown, may be much dilated or scarcely wider than the 
leaf-base. The species is very near indeed to C. purpureo-aureus (C. M.), 
and the two will, I believe, have to be united ultimately. The leaves are, in 
the more robust forms especially, very hygrometric, as in that species. 
This species has given rise to a good deal of doubt as to the proper 
spelling of the specific name. The name as printed in Hedwigia, as above cited, 
is " Bicranum Inerangae Rehm. in Muse. A. Afr. No. 42," and the locality 
is given as " Natal, Ineranga." Now there is no such locality known ; nor 
is it a correct transcription of Rehmann's label, which appears to be un- 
doubtedly Inczanga. (Paris, it may be remarked, has it in Ed. I as Inerangae^ 
which in Ed. II he corrects to Imerangae, making matters rather worse !) 
The point appears to be governed by Art. 57 of the Vienna Rules : " The 
original spelling of a name must be retained, except in the case of a typo- 
graphic or orthographic error." It is clear that C. Mueller's Inerangae falls 
under the first heading, since he definitely cites Rehmann's MS. name, which 
is certainly not Inerangae ; it would clearly therefore be justifiable to change 
it to InczaMgae. This, however, would seem further to involve an " ortho- 
graphic " error. The spelling Inczanga does not correspond to any recognised 
spelling of the locality, but is apparently Rehmann's transcription of the 
native name as it sounded to his ears. The native name has now become 
thoroughly fixed and permanent, and has been, as Mr. Sim informs me, for 
thirty years one of the best known railway- stations in Natal, as Inchanga 
(pronounced Inchanga). It appears to me best, therefore, to adopt this 
spelling. 
Microcampylopus nanus (C. M.) C. M. G-eorge, CP., and Cape Town, 
1916 ; coll. H. A. W. (Nos. 538, 559), c. fr. I found some difiiculty in 
deciding whether these plants should be attributed to M. nanus or to
