Var. robustum * var. nov. (fig. 132). 

 Plant grey-green, not bright green as in type, stouter and more 

 branched, specially above. Inflorescence more leafy and often irregular 

 in form. Flowers paler, sepals longer and broader, petals broader.

A curious form obtained at the Botamc Garden at Hamburg. 

 Its greyish colour and stouter, more branched growth, give it a very 

 distinct appearance, but no difference which could be called specific 

 in the ordinary sense is to be found in the flowers. My plant sends 

 up occasionally a variegated shoot.

 ILLUSTRATION.-Henderson's -■ lUustrated Bouquet, 3. pi. 60. 



Leaves with a marginal stripe of white or cream, stems very pink 

 This is a rather stout form of the species, approaching m this respect

S lineare appears to be a variable plant, as Miquel describes (/oc. 

 cit.) several varieties, differing from the type in stature and habit. 



The specific name refers to the narrow leaves, which were ongmally 

 described by Thunberg (perhaps from dried specimens) as tereti- 

 linearia."

A floriferous and showy species with a wealth of golden-yellow 

 flowers. Easily recognized at any period of growth by its hght-green
