Mlanje District: Mlanje Mountain, 1891, A. Whyte s.n. (Herb. Kew. sub S. 

 aethiopica); ibid., Oct. 1891, Whyte 20 (Herb. Mus. Brit.); southwest ridge, sprawl- 

 ing in shelter of a rock, herb, flowers white, lower lip blotched with purple, 2400 

 m., June 28, 1946, 16492; Luchenya Plateau, gregarious locally in forest re- 

 growths, herb about 1 m. high, subscandent in habit, flowers white, faintly 

 streaked with purple, 1890 m., July 6, 1946, 16700; ibid., gregarious in dense 

 tangles amongst sheltering rocks on grasslands, herb 50-60 cm. high, ascending, 

 leaves rugose, flowers white, flecked with purple, 2100 m., July 11, 1946, 16792 

 (TYPUS in Herb. Kew.). 



This new species, apparently narrowly endemic to Mlanje Mountain, is a north- 

 ern outlying representative of a complex of closely related Cape species. From 

 S. aethiopica, to which it is apparently most closely related, it differs by its 

 constantly 2-flowered verticillasters and dense indumentum, except that S. 

 aethiopica var. hispidissima may have it as dense. 



The distinctions between these species are very small, and perhaps no more 

 than varietal, but if the South African relatives of S. aethiopica are treated as 

 species then I think that the Nyasaland plant certainly has an equal claim. The 

 South African species of Stachys have been revised by Skan in Thiselton-Dyer, 

 Fl. Cap. 5*: 336-367 (1910). 



Leucas milanjiana Gurke, Bot. Jahrb. 22: 141. 1895; Bak. in Thiselton-Dyer, Fl. 

 Trop. Afr. 5: 478. 1900. 

 Zomba District: Zomba Plateau, common on roadsides in Brachystegia wood- 

 lands, perennial herb 30-50 cm. high, stems several, ascending from a thick 

 woody stock, flowers white, 1500 m., June 4, 1946, 16213. Portuguese East 

 Africa, Nyasaland, N. and S. Rhodesia. 



Leucas nyassae Gurke, Bot. Jahrb. 22: 137. 1895; Bak. in Thiselton-Dyer, Fl. 

 Trop. Afr. 5: 485. 1900. 

 ? Leucas villosa Gurke, Bot. Jahrb. 22: 137. 1895; Bak. in Thiselton-Dyer, Fl. Trop. 



Afr. 5: 484. 1900, at least as to the specimen collected by Whyte in Nyasaland. 

 Leucas megasphaera Bak. Kew Bull. 1898: 163. 1898; in Thiselton-Dyer, Fl. Trop. 



*Afr. 5: 488. 1900. 

 Leucas randii S. Moore, Jour. Bot. 38: 464. 1900. 



Blantyre District: Blantyre, in Brachystegia woodlands, herb 20-50 cm. high, 

 aromatic, leaves pale green, flowers white, 1100 m., June 18, 1946, 16359. Kota- 

 kota District: Nchisi, occasional on formerly cultivated ground in Brachystegia 

 woodlands, herb with several reclining and ascending stems about 80 cm. long, 

 flowers dry, colour not ascertainable, 1350 m., Aug. 1, 1946, 17075. Tanganyika 

 Territory, N. and S. Rhodesia, and Nyasaland. 



The type of L. villosa {Stuhlmann 8412 from Ukwere, Tanganyika Territory) 

 is now no longer extant, and nothing exactly matching seems to have been col- 

 lected in that region since. When L. villosa and L. nyassae are combined I there- 

 fore choose L. nyassae as the name, type-gatherings of which (Buchanan 255, 

 460) are in Herb. Kew. The type-specimen of L. randii {Rand 522, from Salisbury, 

 S. Rhodesia) I have examined in Herb. Mus. Brit. 



Leonotis leonurus (L.) Ait. f. Hort. Kew. ed. 2. 3: 410. 1811; Bak. in Thiselton- 

 Dyer, Fl. Trop. Afr. 5: 492. 1900, excl. Whyte 320; R. A. Dyer, Fl. S. 

 Afr. 22: pi. 876. 1942. 

 Phlomis leonurus L. Sp. PI. 587. 1753.
