BRYOPHYTA OF S. RHODESIA. 321 



agrees and is characteristic. The nerve runs out into a stout yel- 

 lowish cuspidate point or even arista, little narrower even at the 

 extreme tip, and there usually ends with a few sharp teeth. The 

 leaves are acute but not narrowly acuminate. The fruit is mostly 

 immature, and it is not quite easy to determine the position in 

 the genus ; the only peristome in at all good condition has the 

 endostome imperfect, and I have not been able to see well-developed 

 cilia; the form of the capsule, however, and its bright red colour 

 in the one or two nearly mature examples, seem to indicate that 

 its position is in Doliolidium, with which the foliage quite agrees. 

 The neck is scarcely narrower than the sporangium, somewhat 

 corrugated, and passing quite abruptly into the seta in immature 

 capsules, but the mature ones seem to show a tendency to taper 

 very slightly and very shortly. 



Bryum mundii CM. — On rock ledge, Salisbury, alt. 5,000 

 feet (Eyles, 2426). 



General distribution: Cape Province. 



Bryum truncorum Borv. — Victoria Falls, alt. 3,000 feet (Sim, 

 8933). 



General distribution : East African Islands, Cape Province, 

 Transvaal, Australia, Tasmania, New Zealand. 



I surmise that this species will be found to have a still wider 

 distribution than the above (? B. andicola Hook., Syn. B. lechleri 

 CM., in South America); the Australian plant (B. leptothecium 

 Tayl.) is certainly identical with Bory's plant. 



Bryum truncorum Bory, nov. var. pycnophylhnn Dixon. 



Folia hand rosulata, ubique aequaliter disposita, dense con- 

 ferta, parum patentia; habitu formarum minorum B. wightii 

 Mitt, indici, sed foliis argute denticulatis. Caespites intus pallidi; 

 folia plerumque breviora quam ea formae typicae. 



Habitat: Zimbabwe, alt. 3,000 feet (Sim, 8737); Umtali, 

 on rock in shade, alt, 5,000 feet (Eyles, 1725). Sterile.

 228 and 557, belong to this species; 228, 228b, 557, 557b, 557c, to 

 the type, 228c to this variety. The variety is very different in 

 habit and leaf arrangement from the type; it exhibits little or 

 none of the interruptedly comose leaf arrangement, and therefore 

 forms a rather undesirable transition between the groups into 

 which Brotherus divides the species of the section Rosulata. 



The plant is in no way a Rhodobryum, under which genus 

 Paris has placed B. syntriehioides CM. 



Rhodobryum commersonii (Schwaegr.) Par. — In mountain 

 bush, Umtali, alt. 4,500 feet (Eyles, 1736) St, 



There appears to be some confusion between this and R. 

 umbraculum (Burch.) Par.; but, as I understand them, R. um- 

 braculum has a more strongly bordered margin, often reddish,
