304 BRYOPHYTA OF S. RHODESIA. 



This agrees well with an original specimen in Hampe's her- 

 barium. The guide-cells of the nerve are very small compared 

 with the cells of the ventral face. 



General distribution : Cape Province. 



Campulopus trichodes Lor.- — Zimbabwe, alt. 3,000 feet (Sim, 

 8749, 8829); Matopos, alt, 5,000 feet (Sim, 8950). All sterile. 

 A highly variable species in colour, size and development of hair- 

 point. 



General distribution : South Africa generally. 



Var. nov. Perlamellosus. Dixon 



Elatus. Costae lamellae superioris altissimae. 



Habitat: Rhodes' Grave, Matopos, alt. 5,000 feet (Sim, 

 8858), St. ; Bed of Tugela River, Natal, alt. 6,000 feet (Dr. 

 Bews, 8374 in herb. Sim) St. 



The dorsal lamellae are pronounced in C . trichodes, and vary 

 considerably, but they are so highly developed here that the plant 

 seems worthy of varietal rank. A section of the nerve near the base- 

 scarcely shows them, but in mid-leaf their height is sometimes 

 actually equal to the thickness of the whole of the rest of the 

 nerve-section. Both the plants referred to the var. are unusually 

 robust, but this may not be more than a coincidence. 



C ampul o-]iu$ inandae (Rehm.) Par. — Zimbabwe, alt, 3,000 

 feet (Sim, 8739, 8740, 8784, 8827) St, ; Rhodes' Grave, Matopos, 

 alt. 5,000 feet, (Sim, 8874)" St, ; Wet Forest, Inyanga, alt. 6,000 

 feet (Henkel, 2635c in herb. Eyles) St. 



This is one of the most striking of the South African species 

 of Campylopus, generally growing in tall, loose tufts with a bronze 

 sheen. It varies greatly in habit, and a single tuft may exhibit 

 several distinct forms. The hair-point appears to be usually only 

 slightly developed, but it may be long and conspicuous. Henkel's 

 plant is shorter, bright green, with falcate leaves, probably a shade 

 form . 



The anatomical structure is distinct, the nerve in section 

 being thin, with the guide-cells very near the front, the ventral 

 layer extremely thin, of very small stereid or substereid cells. 

 The auricles are large and conspicuous, the supra-alar cells all 

 shortly rectangular, not or little narrowed at margin. 



General distribution : Natal. 



Sim's collections contained one or two other species of sterile 

 Campylopus, one quite probably an undescribed one, but their 

 condition scarcely allowed of accurate determination. 



Leucobryaceae. 



Octoblepharum albidum (L.) Hedw. — I have received five 

 gatherings from Southern Rhodesia of this moss, almost cosmo- 

 politan in the tropical and subtropical regions of the world. It 

 reaches as far south as Natal. Recorded also from the Victoria 

 Falls by Brotherus (2).
