M. minutus. I think in all probability all these will have to be reduced 
ultimately to M, pallidisetus (C. M.), of which, unfortunately, specimens 
have not been available.

Compared with Hampe's type at the British Museum.

superne perindistincta, infra apicem percarinatam evanescens. Cellulae 
basilares rectangulares, irregulariter plusminusve elongatae, flavidae, inanes, 
parietibus firmis ; superiores omnes hreviter rectangulares, parietibus trans -

Hob. — On wet stones, Griant's Castle, alt. 7000 ft.. Natal, 1915; coll. 
K. E. Symons, comm. Sim (No. 8665). 
A very distinct species from those hitherto recorded from Africa, and 
showing a connection with a certain Australasian and subantarctic group, 
including D. clathrata H. f. & W., D. vaginata (Hook.), etc., which for the 
most part have smooth cells. A New Zealand species, J), wairarapensis 
Dixon, is still nearer it in the papillose subula, but is very different in habit 
and other respects. 
Gampylopus nano-tenax (C. M.) Par. Woodbush, Transvaal, 1914 ; colL 
H. A. W. (Nos. 56, 130), c. fr. ; Knysna, coll. H. A. W. (No. 507), c. fr. ; 
George, CP. ; coll. H. A. W. (No. 542b), c. fr. 
The different gatherings show some distinctions in length and serration 
of subula, in width of base and of nerve, etc., but they are not constant,, 
even in leaves from the same stem, and they must all be referred to the 
same species. I am not able to distinguish any difference in the vegetative 
characters from 0. Goughii (Mitt.) from India, and the resemblance is 
heightened by a rather unusual peculiarity in the capsule, which here as well 
as in the Indian plant may occasionally be very turgid, glossy, and almost 
entirely without striae. The distribution of the two plants does not at all 
support their identity, and I have not ventured to do more than suggest 
the possibility, but I would draw the attention of bryologists to the 
question.
