upper part that H. riparium shows. The inner phyllaries of the latter seem to have 

 a more pronouncedly apiculate apex than those of H. pachyrhizum, 



Baum 28 in the herbarium of the British Museum (Natural History) is a form 

 of H. riparium with the stem rather quickly glabrescent and brownish, and the 

 leaves less tomentose. The specimen was enumerated by 0. Hoffmann in War- 

 burg, Kunene-Sambesi Exp. 412 (1903) as H. pachyrhizum Harv., and the locality 

 as "vor Ediva" at 930 m. The cited locality is that on the label of the British 

 Museum specimen.

Mlanje District: Mlanje Mountain; Luchenya Plateau, occasional on rocks in 

 open grasslands, herb 30-50 cm. high, forming a compact grey bush, flowers dull 

 white, 1870 m., June 27, 1946, 16458; ibid., frequent in rocky grasslands, herb 

 30-40 cm. high, habit bushy, flowers yellow, bracts dull white, I960 m., July 16, 

 1946, 16851. Endemic to Nyasaland. 



H. sordidum differs from H. syncephalum Baker in the very branched bushy 

 habit, with numerous and more slender stems, much smaller and more closely set 

 leaves, smaller, more compact and scarcely pink-tinged corymbs. Moeser (I.e.) 

 sinks H. sordidum under H. syncephalum, but I disagree with this opinion. Both 

 species have been re-collected since, and there is no sign of intermediates.
