306 BRYOPHYTA OF S. RHODESIA. 



3 mm. Folia multijuga, 1.5 mm. ad 1.75 mm. longa, confertius- 

 cula, late elliptico-oblonga, obtusa vel apiculata; lamina vaginalis 

 vix dimidiam partem superans, lamina dorsalis ad basin folii 

 attingens ibique cito aiigustata. Costa validiuscula, infra sub- 

 ferruginea, infra apicem soluta. Lamina vaginalis limbo saepe 

 rufescente sat valido, 2 ad 4 seriato circumdata ; lamina dorsalis 

 et apicalis nunc angustissime limbata, nunc omnino iinmarginatn . 

 Cellulae majusculae, 12/x ad 16/x latae, subquadratae, percldoro- 

 ph yllosae , laeves, parietibus tenuibus. Fructus ignotus. 



Habitat: Palm Grove, Victoria Falls, alt. 2,500 feet (Sim, 

 8819). 



A very beautiful and distinct species, with prettily plumose 

 foliage, almost elliptical, often obtuse leaves, nerve ceasing dis- 

 tinctly below apex, and large, highly chlorophyllose cells. The 

 border (except on the vaginant lamina) is very narrow, often in- 

 distinct, sometimes altogether wanting, sometimes indicated only 

 by occasional elongate 1-2-seriate, but not cartilaginous cells 

 The species might, therefore, be considered to belong to the 

 Semilimbidium ; but the occasional full development of the border, 

 together with the character of the aerolation, leave little doubt 

 that its true place is in Bryoidium. 



Semilimbidium. 



Fissidens micro-androgynus sp. nov. Dixon. 



/'. androgyno Bruch structura, inflorescentia synoica, etc., 

 similis, midto tamen pusillior, vix 0.5 cm. altus ; folia 5 ad 7 juga, 

 remotiuscula, omnino nisi apud laminam vaginant em immarginata, 

 ibique angustissime limbata. Seta perbrevis, 3 mm. alta; theca 

 perminufa, brevis, erecta vel inclinata, sicca urceolata, operculo 

 conico, acuto. 



Habitat: Bulawayo (Wager, 895). 



Almost a miniature of F. androgynus Bruch, but totally dis- 

 tinct in the size and the characters italicised. The synoicous 

 inflorescence and the pale, chlorophyllose, clear, smooth cells, will 

 distinguish it from others of the South African Semilimbidia. 

 The very narrow border is frequently to be found only on the 

 upper, or the perichaetial leaves, the lower leaves being entirely 

 unbordered. 



Fissidens submarginatus Bruch. — On ant-hill in granite 

 country, Umtali, alt. 3,700 feet (Eyles, 1742). 



General distribution : Cape Province, Natal. 



Aloma. 



Fissidens calochlorus sp. nov. Dixon. 



Pusillus; dense caespitosus intense laete viridis. Caulis fer- 

 tilis circa 2 mm. longus, paucijuga ; sterilis paullo longior, pluri- 

 juga. Folia caulis fertilis ligulato-lanceolata, acuta, raro breviter 

 acuminata; lamina vaginalis dimidiam partem folii superans, 

 lamina dorsalis ad folii basin attingens, ibique saepe rotundata; 

 omnes immarginatae, integrae ; costa valida, concolor, flexuosa,
