BRYOPHYTA OF S. RHODESIA. 329 



7846, 8752 p.p., 8824); Matopos, alt. 5,000 feet (Sim, 8848). 

 Nos. 8824, 8848 have the areolation a little more distinct, and the 

 nerve a little narrower than in the type. 

 General distribution: Transvaal. 



Lindbergia patentifolia Dixon. — Zimbabwe, alt. 3,000 feet 

 (Sim, 8774) c.fr. The fruit has not been observed. It does not 

 appear to differ materially from that of the other South African 

 species. 



General distribution: Uganda. 



Pseudoleskea claviramea (CM.) CM. — Zimbabwe, alt, 3,000 

 feet (Sim, 8759, 8794). 



General distribution: Cape Province, Transvaal, Orange River 

 Colony, Zululand, East tropical Africa', Madagascar. 



Pseudoleskea lesheoides Schimp. — Zimbabwe, alt. 3,000 feet 

 (Sim, 8756, 8775). I find it increasingly difficult to separate 

 this from P. claviramea. 



General distribution: Cape Province, Natal, Transvaal. 



llauia abbreriata (Broth.) Broth. — Zimbabwe, alt. 3,000 feet 

 (Sim, 8774b); Khami Ruins, 5,000 feet (Sim, 8863). 



General distribution: Shire Highlands, German East Africa. 



Thuidium versicolor (Hornsch.) Schimp. — Victoria Falls, on 

 stems of trees (Brunnthaler) (2). 



General distribution: Cape Province, Natal, Zululand, East 

 tropical Africa. 



Thuidium borbonicum Besch. — Victoria Falls, alt. 3,000 feet. 

 (Cheeseman, September, 1905, comm. M. B. Slater; Sim, 8893; 

 Miss Farquhar, 23 ; Wager, 908) St. 



General distribution : Natal, Uganda, Bourbon. 



Hypnaceae. 



Drepanocladus sparsus CM. — Victoria Falls (Wager, 902) St. ; 

 Makoni, alt. 4,700 feet, on earth by running water (Eyles, 787) 

 St. 



General distribution: Cape Province, Orange River Colony. 

 " Amblystegiinn variuni Lindb. — On stones by stream, 

 Mazoe, alt, 4,600 feet (Eyles, 402.)" (8) This proves, from an 

 original specimen sent me by Dr. Sim, to be Isopterygium aquati- 

 cum sp. nov. ; v. infra.] 



Microthamninm pseudo-reptans (CM.) Par. 



Syn. Tlypnum glabrifolium CM. in "Flora," 1890, p. 496. 

 Microthamnium glabrifolium "Par. Ind.," p. 809. 



M . glabrifolium is entirely indistinguishable from M . pseudo- 

 reptans. C Mueller suggests no differences in his description, 

 while he acknowledges the resemblance when he asks whether the 

 planE referred by Mitten to M. pseudo-reptans may not be his 

 M . glabrifolium.
