PLANTS COLLECTED IN NYASALAND 



89 



Kniphofia sp. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, scattered in open grass- 

 lands, perennial herb about 2 m. high, leaves contain a very strong fibre, cf. col- 

 lection from Zomba Plateau, I960 m., July 15, 1946, 16850*. 



This may well be K. ensifolia Bak. and conspecific with 16323, but as the 

 most important characters are floral, and 16850 is in fruit, I feel that it is best 

 left unnamed. No flowering Kniphofia that could correspond with 16850 has so 

 far been collected on Mlanje Mountain. 



Aloe buchanani Bak. Kew Bull. 1895: 119. 1895; in Thiselton-Dyer, Fl. Trop. Afr. 

 7: 457. 1898; Christian, Fl. PI. S. Afr. 20: pi. 763. 1940. 

 Zomba District: Zomba Plateau, occasional in Bracbystegia woodlands, per- 

 ennial herb about 1 m. high, leaves weak and spreading, channelled, fleshy, 

 green, mottled with white, roots tuberous, peduncle erect, flowers brownish-pink, 

 tipped with green, 1500 m., June 4, 1946, 16228. Confined to Nyasaland.

PI. S. Afr. 20: pi. 762. 1940. 

 North Nyasa District: Nyika Plateau; Nchena-chena Spur, common in short 

 grass of slopes, shrub 60-80 cm. high, leaves pale green, spotted with white, 

 whole inflorescence orange-red except for green tips of sepals and petals, 2000 

 m., Aug. 10, 1946, 17147; ibid., common in open grassland, shrub 70-100 cm. 

 high, underside of leaves mottled with white at base, flowers orange-red, apex of 

 petals and sometimes of sepals green, 2000 m., Aug. 20, 1946, 17369. Tanganyika

Aloe sp. nr. lateritia Engl. Pflanzenw. Ost-Afr. C: 140. 1895. 



North Nyasa District: Nyika Plateau, gregarious on dry rocks in grassland, 

 shrub 35-50 cm. high, stem simple, very short, leaves purplish-brown, incurved 

 and forming a cup-shaped rosette, flowers and pedicels orange-red, peduncle 

 brownish-purple, covered with a glaucous bloom, simple or once-forked, erect, 

 fruit 3-angled, soft, up to 2.5 cm. long and 1.5 cm. in diameter, 2250 m., Aug. 11, 

 1946, 17184. 



This differs from A. lateritia (Tanganyika Territory) in the inflorescence 

 which is simple or only once branched, and in the leaves which form a cup-shaped 

 rosette; it also resembles A. duckeri Christian, but likewise differs in that the 

 inflorescence does not have 5-6 branches as in that species. 



Aloe chabaudii Schonl. Gard. Chron. III. 38: 102. /. 34 (1905) var. mlanjeana 

 Christian, Fl. PI. S. Afr. 18: pi. 698. 1938; Reynolds, Aloes S. Afr. 342. 

 1950. 



Mlanje District: Mlanje Mountain, plentiful in both wet and dry situations on 

 open rock-faces, 50-80 cm. high, leaves in a basal rosette, very thick and fleshy, 

 numerous, curved upward and surrounding the panicle, panicle about 35-50 cm. 

 long, not much exceeding the leaves, branches spreading, flowers yellow to 

 orange or red on different plants, a very attractive species (colour photos.), 1420 

 m., June 24, 1946, 16411. The var. only on Mlanje; the species in Portuguese 

 East Africa, Nyasaland, N. and S. Rhodesia, the Transvaal, and Swaziland. 



I do not feel quite certain that Mr. Brass* plant is the variety.
