322 BHYOPIIYTA OF S. RHODESIA. 



with shorter, scarcely spinose teeth, while R. commersonii has the 

 border less marked ( 1 rarely or not reddish) and the teeth densely 

 spinose, almost ciliate. 



Rhizogoniaceae. 



Rhizoyonium spiniforme (L.) Bruch. — In wet forest, Inyanga, 

 alt. 6,000 'feet (Henkel, 2632, in herb. Eyles). 



General distribution : Tropical and snb-tropical zones, gener- 



ally. 



Bartramiaceae. 



Bartramidula globosa (CM.) Broth. — Matopos, alt. 5,0C0 

 feet (Eyles, 1050). 



The specimen I have seen of this, sent me by Dr. Sim, was 

 without fruit, but a single inflorescence was present, which, on 

 dissection, proved to be synoicous. Apart from the dioicous 

 inflorescence (fide Brotherus) and the warted capsule in B. comosa 

 (Hpe. and CM.) T find nothing to separate that species from the 

 present; vegetatively the two appear to me to be identical. 



General distribution: Cape Province, Natal. 



Philonotis androgyna (Hampe) Jaeg. — Victoria Falls, alt. 

 3,000 feet (Sim, 8944). 



General distribution : Cape Province, Natal, Transvaal. 



Philonotis imbricatula (Mitt.) — In various forms and under 

 several gatherings from Zimbabwe, Khami, the Matopos and 

 Victoria Falls. All sterile. 



I have not attempted to give the distribution (which is a 

 very wide one) as the limits of the species are not well defined and 

 it is doubtful whether it be distinct from several other described 

 species that are at least closely allied. It was first described from 

 the East Indies. I have a plant from Fiji which I cannot separate 

 from it, and I doubt if /'. etessei Broth, and Par. from New 

 Caledonia can be kept distinct. 



Philonotis laxissirha (CM.) Bry. jaw — Floating on lime- 

 impregnated water of Sinoia Cave, Lomagundi, alt. 3,900 feet (Dr. 

 Nobbs, 2547, in herb. Eyles) St. Dr. Nobbs wrote that it grew 

 in round clusters, and free, with an accretion of lime below. It 

 strongly repelled the water when submerged. It is a curious and 

 very delicate growth, much encrusted with ( ?) sulphate of lime. 

 It agrees very well with other specimens of P. laxissima which 

 I have from Africa and elsewhere, and though under the abnormal 

 circumstances of growth its specific characters may well have 

 become masked, I think it may safely be referred here. 



General distribution : Assam, East Indies, New Hebrides, 

 Madagascar, Natal, Egypt. 



Philonotis laeviuscida sp. now Dixon. 



Philonotula. Sat. robusta, circa 5 cm. alta, flavo-viridis.
