BRYOPHYTA OF S. RHODESIA. 327 



Fructus ignotus. 



Habitat: Makoni (Dr. Nobbs, 1317b, in herb Eyles). 



This is, I think, the most robust species of the genus hitherto 

 described. T. bo'rgenii (CM.) from Madagascar comes near it 

 (and if, as Cardot suggests, that should prove to be a robust form 

 of T. fabronioides, it is probable that this may also have to be 

 reduced), but is more slender, with laxer branch leaves, and hence 

 less turgid branches. T. dilatatum Ren. has the stem leaves very 

 broad, wider in fact than long, which is not the case here. 



Stereophi/ll urn odontoealyx (CM.) Jaeg. — Tree Trunk, 

 Mazoe, Tatagura Valley, alt. 4,300 feet (Eyles, 652, 713); 

 Umtali, alt. 4,000 feet (Eyles, 1743); Great Zimbabwe Temple 

 Ruins, alt. 3,000 feet (Sim', 8755); Victoria Falls, alt. 3,000 feet 

 (Sim, 8888, 8889, 8908, 8912, 8918, 8921, 8923; Wager, 913; 

 Eyles, 1304). All fruiting. 



Several of the Victoria Falls gatherings show a dark green, 

 robust, luxuriant form with long stems and large leaves, long 

 seta (to 2 cm.), and usually with fewer capsules — probably a 

 hygromorph. 



General distribution : Cape Province, Transvaal, Natal, 

 German East Africa, Uganda. 



Fabroniaceae. 



Fabronia abi/ssinica CM. — On earth between rock and tree, 

 Salisbury, alt. 4,900 feet (Eyles, 684a); Bulawayo, alt. 4,500 feet 

 (Eyles, 1053); Zimbabwe, alt. 3,000 feet (Sim, 8762, 8769, 8803, 

 8804); Matopos, alt. 5,000 feet (Sim, 8855); Victoria Falls, alt. 

 3,000 feet (Wager, 905). All, or nearly all, fruiting. 



No. 8804 is a lax, dark green form, with short hair-points, 

 which might be a distinct species, but it does not seem to agree 

 quite with any of the other described species, and is probably a 

 shade form of this. 



General distribution: South and East Africa generally. 



Fabronia perciliata CM. — Rua R., near Salisbury, alt. 5,000 

 feet (Eyles, 1323); Victoria Falls, alt. 3,000 feet (Sim, 8907b). 



I have received, by the kindness of the authorities of the 

 Berlin Museum, an original specimen of C. Mueller's species, which 

 shows that it is by no means one of the species with highly ciliate 

 leaves, as the name and to some extent the description would 

 imply. It differs little indeed from the common Torms of F. 

 abyssinica, so little indeed that I doubt much if it be really dis- 

 tinct; but I retain it temporarily. The South African species of 

 this genus need carefully revising. 



General distribution: Cape Province, Natal, Transvaal. 



Fabronia angolensis Welw. and Duby. — Zimbabwe, alt. 3,000 

 feet (Sim, 8815); Salisbury, alt. 4,900 feet, on tree trunk; and 

 on vertical granite in shade (Eyles, 1573, 1575). The latter has 

 short points, and may be referred to var. acuminata Gepp.
