^18 THE JOL^KXAL OF BOTANY 



Ovarium 1 ram,, stylus 1'75 mm. long. Capsula fusco-brunnea, 

 glabra, 3-5 X 25 mm. 



Near B. quangensis Engl., B. suhcapitata Engl, and B. pulchra 

 Skan, but distinguished on sight by the indumentum and retention of 

 colour when dried. It would seem closer still to B. affinis De Wild., 

 known by description only, which has much larger lower leaves and 

 more or less amplexicaul upper 'ones, lowermost bracts as long as, or 

 a little longer than, the inflorescences, differently-shaped upper bracts, 

 smaller calyx with only 4 (and smaller) teeth, narrower corolla lobes, 

 and larger beaked capsules. 



To get the above measurements of bracts, bracteoles, and cal3^x, it 

 is necessary to select perfectly expanded flow^ers, as those not quite 

 so advanced have those organs smaller. 



Buchnera Gos^weileri, sp. nov. Caule ascendente simplici vel 

 perpauciramoso leviter scabriusculo ; foliis sessilibus caulinis oblongis 

 vel oblongo-lanceolatis obtusis basi 3-7-nervibus supra scabridis subtus 

 leviter scabriusculis ; sj)icis densifloris primo ovoideis postea oblongis 

 pedunculis folia superantibus insidentibus ; hracteis calyce paullo 

 bi*evioribus ovatis acuminatis margine ciliolatis dorso scabriusculis ; 

 hracteolis spathulatis acutis longit. bracteas circa semisequantibus ; 

 caJycis late cylindrici 9-nervis lobis 5 inter se inaequalibus triangu- 

 laribus acutis ; corollce tubo calycem duplo superante lobis suborbicu- 

 laribus margine leviter ciliolatis; filamentis omnibus glabris antheris 

 optime acuminatis. 



Angola, forests of Mudobua ; Gossiceiler, 1059. 



Planta circa spithamea. Folia plerumque 3-4 cm. long., 8-11 mm. 

 lat. Pedunculi segre usque 10 cm. long, saepius vero breviores. 

 Spicse primo 10-15 x 10-12 mm., posthac usque saltem 2*5 cm. elon- 

 gatse. Bracteae 3-3*5 mm. long., inferne 2'5 mm. lat. Bracteolse fere 

 2 mm. long. Calyx 4*5 mm. long., 2 mm. lat. ; lobi 1-1 "5 mm. long. 

 CoroUae tubus 8x1*5 mm.; lobi segre 3 mm. diam. Filamenta 

 longiora 1 mm. long. Ovarium ovoideum, segre I'O mm. long. ; 

 stylus ovario sequilongus. 



B. ensifolia Engl., to which this comes closest, has narrower 

 (linear-lanceolate) leaves, broader bracts glabrous except for the 

 ciUate margin, a shorter and broader calyx, and corollas with smaller 

 lobes. In addition, its leaves have but one nerve, and though the 

 nerves of the other are difficult to see on the upper side of the leaf, 

 they are very plain on the lower face, especially near the base. 



Buchnera grranitica, sp. nov. Herba hispidule scabrida circiter 

 spithamea; caule subsimplici erecto angulato folioso ; foliis ssepissime 

 oppositis basalibus rosulatis oblongis vel oblongo-ovatis obtusis mani- 

 feste (interdum obscure) trinervibus ceteris linearibus vel lineari- 

 oblongis mucronatis ; spicis foliis brevioribus ovoideis basi parum 

 interruptis ; hracteis lanceolatis acutis uti caWx extus hispidule 

 scabridis ; hracteolis calyce multo brevioribus linearibus acutis ; 

 calyce 9-nervi lobis 5 abbreviatis subulatis ; corollce tubo ex calyce 

 plane eminente sub limbo hispidulo lobis obovatis obtussimis ; jila- 

 mentis omnibus glabris antlieris acuminatis.
