Transvaal, Lydenburg, Pilgrim's Rest and Sabie ; nn. 14319, 

 18670. 



Planta verisimiliter 1-2-spithamea. Folia inferiora +12x6 mm., 

 superiora pleraque 12-15 X 4-7 mm., in sicco viridia vel brunnescentia ; 

 petioli dum adsint summum 3 mm. long. Pedunculus 3-7 cm. long. ; 

 hujus bractese sparsa? lineares vel lineari-lanceolatse, i 6 mm. long. 

 Capitula pansa circa 15 mm. diam. Involucrum 5*5 x 7 mm. ; hujas 

 phylla 4-5 mm. long. Ligubne 5 mm. long. Achaenia 1 mm. long. 



Has all the floral characters of the plant figured in Hook. Tc. 

 Plant, t. 1109 and so belongs to a very small and little known genus. 

 In foliage it is ver}" distinct.

Folia pleraque 2-3 x 1*2-2 cm. ])etiolo 7-15 mm. long, et 2 mm. 

 lat. exempto, in sicco viridia vel brunnea. Pedunculi circa 1 cm. 

 long. ; horura bracteie lineares, hii-tuhe, circa 2 mm. long, Capitula 

 pansa (sicca) 1x1*2 cm. Involucri phylla pillida, extima 2-3 mm., 

 intermedia 4-6 mm., intima 7 mm. long. Ligulai albie, oblongse, 

 apice bidenticulatae, 7*5 mm. long. Floseulorum int. corolke lutea?, 

 6*5 mm. long. ; harum tubus infei-ne tenuis superne gradatim 

 ampliatus. J^tyli rami 1 nnn. long. Aelueuia 1 mm., pappi seta? 

 5 mm. long. 



The plant upon which Klatt founded this genus is a native of 

 South- West Africa ; by the discover^', therefore, of a Transvaal 

 species the distribution of Pentatrichia receives a notable extension. 

 The new plant can immediately be recognized by its winged petioles 

 and radiate heads. Tliis latter character necessitates a slight modifi- 

 cation in the generic description. 



The outer pappus of P. alata consists of very minute scales 

 almost invisible except under the compound microscope. 

 (To be concluded.)
