366 MR. SPENCER MOORE ON THE 
Hab. Near Lake Tanganyika; G. F. Scott Elliot, no. 8352. 
Caulis 0°4 cm. diam., intervallis brevibus vestigiis vel saltem 
cicatricibus foliorum transitorum onustus. Folia circa 6:0 cm. 
long., 0°6-0°9 cm. lat. Peduneuli circa 20-30 cm. long., 
araneosi, bracteis parvis scalariformibus instructi. Capitula 
circa 2:0 em. long. et 2°5 cm. lat. Involucri phylla extima 
0°3-0°4 cm. long., fere 0°3 cm. lat.; interiora usque ad 1°2 cm. 
long., intima 1:7 cm. long., 04 ecm. lat. Corolle tubi pars 
attenuata 0°8 cm., pars ampliata vix 0°2 cm. long.; lobi 0°7 cm. 
long. Achenia 1:0 em., pappi sete usque ad 1°3 cm. long. 
Judging from Dr. Hoffmann’s clavis (Bot. Jahrb. xv. p. 536), 
this is nearest Pleiotavis affinis, O. Hofim., a species which I 
have not seen. From this it differs inter alia in the shape and 
size of its leaves and pubescent achenes. According to Hoffmann, 
P. affinis is very like P. rugosa, O. Hoffm., which has heads 
differently shaped from those of Mr. Scott Elliot’s plant, with the 
involucral leaves in many series, there being several series of very 
small outer ones for instance. In this characteristic I presume 
that P. affinis shares, this being another and important point 
of difference between it and P. vernonioides.
