(Concluded from p. 257.) 



Gynura Brownii, sp. nov. Verisimiliter scandens caule satis 

 folioso longitrorsum striate glabro, foliis petiolatis ovatis dentato- 

 lobiilatis basi obtusis rotundatisve giabris petiolis amiculatis, 

 capitulis mediocribus circa 40-liosciilosis in paniculam corymbi- 

 formem subdensam terminalem dispositis, pedunculis propriis 

 involucrum subaequantibus giabris, involucri anguste campanulati 

 pbyllis circa 12 oblongis sub apice angustatis apice acutis dorso 

 carinatis leviter papillosis additis calyculi phyllis paucis parvis 

 linearibus, corollis exsertis liavis, achaeniis adhuc maxime crudis 

 anguste cylindricis pilosis quam pappi setaB scabriusculse albae 

 multo brevioribus. 



Hab. Uganda,- Umbendi road 100 miles N.W. of Kampala ; 

 E. Broivn (Dilmmer 2723). 



Folia ± 3 cm. long., circa 2 cm. lat. ; petioli 7-15 mm. long,, 

 hujus auricuhe late reniformes, amplexicaules, raridentatae vel 

 fero omnino integras, circiter 5x7 mm. Inflorescentiae pedunculus 

 3-5 cm. long. Paniculae 4-5 x 5-6 cm. Pedunculi proprii graciles, 

 5-8 mm. long. Capitula 10 x 6 mm. Involucri phylla 7 mm. 

 long., in sicco brunnea, margine anguste scariosa. Calyculi 

 phylla 3 mm. long. Corollas inferne angustae (ima basi paullo 

 amplificatae), sub limbo subito dilatato, 9 mm. long. Styli rami 

 2-5 mm. long. Ach^enia 1-25 mm., pappus 8-5 mm. long. 



On sight this differs from G. Taylori S. Moore in the auricled 

 leaves and larger heads with more numerous involucral leaves. 

 G. Meyeri-Johmmis & G. Fischeri, both of 0. Hoffmann, are not 

 represented at the Museum, but, according to the respective 

 descriptions, diverge in several respects from the plant under 

 notice ; moreover as Hoffmann says nothing about the style-arms, 

 they may both turn out to be species of Crassocephalum. 



Gynura Buntingii, sp. nov. Herbacea, prostrata vel 

 scandens, fere glabra ; ramis e caule undulato nudo vel fere nudo 

 as«endentibus sparsim foliosis ramulos abbreviates plurifoliosos 

 hac atque iliac emittentibus ; foliis sessilibus subsessilibusve 

 lanceolatis vel lanceolate- oblongis rare lanceolato-ovatis obtusis 

 vel obtuse acutis basi obtusis acutisve integris nonnunquam 

 margine undulatis membranaceis prime sub lente pilesulis necnen 

 margine ciliatis cite giabris ; capitulis homogamis circa 27- 

 fiosculosis pre rata majusculis campanulatis in corymbum ter- 

 minalem ohgocephalum satis longe pedunculatum bracteatum 

 laxum digestis ; involucri phyllis 13 linearibus acuminatis 

 marginibus membranaceis giabris additis calyculi phyllis paucis 

 linear! subulatis quam sese multo brevioribus ; flosculis luteis 

 involucrum subasquantibus ; achaeniis anguste cylindricis 10- 

 costatis giabris ; pappi setis levibus albis.
