Oban ; nn. 2021, 2074. 



Twining by means of a rather slender chocolate-coloured, when 

 dry prominently striated, somewhat verruculose stem. Leaves drying 

 brown-green, covered with very short scabrous emergences and 

 provided with a vast number of minute glands pellucid in transmitted 

 light, mostly 10-13 x 6-8 cm., though occasionally only 7-8 x 4 cm., 

 -the terminal cusp about 1 cm. long; lateral nerves about 7 pairs, 

 inserted upon the midrib nearly at a right angle ; petioles ± 2 cm. 

 long. Stipules rigid, chocolate-coloured, about 3 mm. long. Panicles 

 7-11 cm. long and about 3-5 cm. across. Peduncles 8 cm. long; 

 pedicels 5-8 mm., and bracts barely 2 mm. Segments of calyx 

 1-5 X 1-1-25 mm. Corolla bright j)urple inside, paler within ; tube 

 scarcely 2 mm. long ; lobes 7x3-5 mm. Corona ■ 3 mm. long, its 

 lobes erecto-patent, -75 mm. long. Free part of filaments -5 mm. 

 long; anthers 1-5 mm. long. Pollinia rhombic, including the stalk 

 1-25 mm. in length. Obtusely conical apex of style about '5 mm. 

 long. Follicles dark brown, 8-8-5 cm. long, about 2 cm. broad. 

 Seeds 5 mm. long, 2 mm. broad, ovate-lanceolate unilaterally keeled, 

 •except for the 2-5 cm. long (pale brown) coma glabrous. 



Easily distinguished from B.ptirpurea N.E. Br., hitherto the only 

 known species, by the scabrid leaves drying brown, the Jihort in- 

 florescences and the much smaller flowers. 



Var. grandifolia var. nov. A typo discrepans ob folia 

 majora, sicca fusca, necnon corollas majores. 



Oban ; n. 63. 



Stems purplish, warted. Leaves 15 x 9 cm. Corolla-lobes 



10 x 4-5-5 mm. 



This looks very different from the type, and should possibly be 

 regarded as a distinct species. 



Secamone conostyla S. Moore sp. nov. Planta caule volubili

 superioribus oriundis simplicibus dichotomeve paniculatis paten- 

 tibus paucifloris ; hracieis minimis lanceolatis ; pedicellis ut 

 peduncull tiliformibus glabris ; floribus quam pedicelli manifeste
