308 BRYOPHYTA OF S. RHODESIA. 



rigide falcata vel hamata, 2 mm. ad 2.5 mm. longa, e basi latiore 

 /(iff oblonga apice abrupte obtuse acutata, apiculata, nee acu- 

 minata; lamina vaginalis circa 2/3 folii longitudinem attingens; 

 lamina dorsalis ad basin folii accedens ibique auriculata margines 

 omnes tenerrime crenulati. Costa valida, concolor, superne plus 

 minusve sinuosa, percurrens. Lamina folii superne madida •plus 

 minusve for titer transverse rugosa. Cellulae perchlorophyllosae. 

 pellucidae, laeves, 9/i to 12/i, latae, subrotundatae, marginales hand 

 distinctae. 



Cetera ignota. 



Habitat: Victoria Falls, alt. 3,000 feet (Sim, 8885, 8904, 

 8924 p.p. 8928); Matopos, alt. 5,000 feet (Sim, 8878). 



This species appears best placed in this section rather than 

 in Amblyothallia. It has no near allies among the African 

 species; the nearest perhaps is F. procerior Broth, and Bryhn ; 

 but there, as in F. cymatophyllus CM. and F. amblyophyllus 

 CM., the texture is quite different, the leaves much longer and 

 narrower, ligulate, and with a different nerve. They are also 

 without a transverse corrugation which is very constant here, and 

 a marked feature when moist. 



I must confess to a little suspicion as to the origin of No. 

 8878. Dr. Sim tells me that he thinks there is no doubt that the 

 data are correctly given. The species is, however, in all the other 

 gatherings definitely hygrophytic in its habit and associates, and 

 it seems a little remarkable that a single gathering should come 

 from the Matopos, while betraying no difference whatever in 

 character. The collecting number, moreover, is the last of those 

 belonging to the Matopos, the following and succeeding numbers 

 being from the Victoria Falls. 



OCTODICERAS. 



Fissidens julianus (Savi) Schimp. — Mazoe, alt. 4,600 feet, 

 submerged (Eyles, 401) ; Palm Grove, Victoria Falls, alt. 2,500 

 feet (Sim, 8917) ; Victoria Falls (Wager, 911) ; Umtali, in running 

 stream, alt, 3,800 feet (Eyles, 1663). All sterile. 



General distribution. — Aquatic. Very widely spread in north 

 and south temperate latitudes. 



Calymperaceae. 



Galymperes victoriae, sp. nov. Dixon.

 circa 0.5 cm. altum, viride. Folia sicca convoluta. Hamato- 

 incurva, madida explanata, concava, 2 mm. ad 3 mm. longa, 

 supra basin brevem angustiorem paullo 1 constricta, inde oblongo- 

 ovata, apice paullo angustata, obtusa, marginibus ad medium 

 folium feriebus duabus cellularum bistratosis, crenulatis vel hie 

 illic minute denticulatis ; costa validiuscula, 45/x ad 50/a lata; 

 per totam longitudinem subaequalis, seu sensim superne paullo 

 angustata, dorso papillata. Cellulae basilares endohyalinae
