lobules on the petiole itself; the phyllaries are very slightly longer than else- 

 where. These do not seem to reflect more than local variation, which it may be 

 possible to classify more satisfactorily in the future. The following specimen 

 in the Kew Herbarium is the same as Brass 16415: 



Mlanje District: Tuchila Plateau, plant 60-90 cm. high, flowers yellow, 1830 

 m., Aug. 1901, /. M. Purves 65. 



Senecio syringifolius O. Hoffm. Dot. Jahrb. 20: 236. 1894. 

 Senecio exsertiflorus Bak. Kew Bull. 1898: 154. 1898. 



Senecio nyikensis Bak. Kew Bull. 1898: 154. 1898; non S. nyikensis Bak. Kew Bull. 



1897: 271. 1897. 

 Senecio subpetitianus Bak. Kew Bull. 1898: 303. 1898. 



Zomba District: Zomba Plateau, climbing on swampy edge of rain-forest, vine 

 6-8 m. high, fruit-pappus white, 1770 m., May 31, 1946, 16117. North Nyasa Dis- 

 trict: Nyika Plateau, frequent on edges of montane forest, vine climbing 6-10 m., 

 leaves more or less fleshy, florets greenish-white, anthers and stigmas yellow, 

 2320 m., Aug. 16, 1946, 17236. Uganda, Kenya, Tanganyika Territory, and 

 Nyasaland. 



Near S. tamoides DC. Prodr. 6: 403 (1838), but with discoid capitula. 



Senecio rectiramus Bak. Kew Bull. 1898: 155. 1898. 



Kota-kota District: Nchisi Mountain, common on edge of rain-forest, vine 

 climbing to a height of 10 m. by means of sensitive petioles, leaves grey below, 

 flowers yellow, 1400 m., July 27, 1946, 16987. Endemic to Nyasaland. 



Senecio auriculatissimus Britten, Trans. Linn. Soc. II. Bot. 4: 21. 1894. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, frequent on banks of 

 stream in forest, subscandent shrub 2-3 m. high, more or less fleshy, just coming 

 into flower, flowers yellow, 1900 m., July 3, 1946, 16635.* Endemic to 

 Nyasaland. 



Senecio milanjianus So Moore, Jour. Linn. Soc. Bot. 35: 359. 1902. 



Senecio tropaeolifolius O. Hoffm. Bot. Jahrb. 30: 437. 1901; "non S. tropaeolifolius 



MacOwan, Hook. Ic. PI. pi. 1011. 1867. 

 Senecio conradi Muschl. Bot. Jahrb. 43: 43. 1909. 



Mlanje District: Mlanje Mountain, southwest ridge, frequent on flat dry rocks, 

 herb 40-60 cm., flowers bright yellow, showy, plant very fleshy, 1 or 2 stems 

 erect from a tuberous stock, 2400 m., June 28, 1946, 16496; Luchenya Plateau, 

 common epiphyte in forest, 30-50 cm. high, fleshy, simple, erect, flowers yellow, 

 showy, 1820 m., July 5, 1946, 16677.* Tanganyika Territory and Nyasaland. 



S. Moore distinguishes his S. milanjianus from So tropaeolifolius O. Hoffm. by 

 the hompgamous heads and more lobed leaves. The capitula on the type-specimen 

 of So milanjianus are so ancient and over-ripe, that I feel that too much hope and 

 intuition entered into the confident assertion of their homogamy; especially as 

 two excellent gatherings from Mlanje Mountain (Brass 16677, Purves 53) agree 

 very well with the type of S. milanjianus except for their obviously radiate heads. 

 At present I am not inclined to give specific importance to the degree of lobing 

 of the leaves. 



Senecio peltophorus Brenan, sp. nov. 



Affinis est S milanjiano S. Moore, sed ut videtur terrestris nec epiphyticus 

 vel saxicolus, foliis multo minoribus, bracteis supremis et bracteolis brevioribus, 

 capitulis multo minoribus, flosculis paucioribus, ligulis et pappo brevioribus 

 differt. 



Herba perennis, glabra, carnosa, 12-40 cm. alta, caulibus erectis e rhizomate 

 crasso ramoso siccitate albido circiter 0.6-1 cm. diametro exorientibus; folia
