both sides, apparently olive-green ; corona-lobes apparently white ; 
lobes of the outer series 1 lin. long, simple, narrowly oblong-linear, 
often bifid or emarginate at the apex, gibbous or thickened on the 
inner face ; lobes of the middle series divided nearly to the base 
into 3 segments 3—1} lin. long, rising to the level of the apex of the 
style or exceeding it, the middle segment linear, with a compressed 
gibbosity or thickened keel at the middle, sometimes nearly obliterated 
in dried specimens, the lateral usually linear, without auriculate 
inflexed sides at the base; lobes of the inner series 3—} lin. long, 
entire, narrowly oblong-linear or linear-lanceolate, subacute or 
obtuse, with the tips pressed against the basal part of the style apex, 
which is either stout and oblong or ovoid-oblong, or more slender, 
much elongated or narrowly conical, and apparently angular, 
produced about 3 lin. beyond the very short erect rounded anther- 
appendages ; staminal column } lin. long. Spreng. Syst. Veg. i. 854 ;

The apical part of the style in this species seems to vary very much in stoutness, 
and E. Meyer founded 8 species upon the character of the style, but the distinction 
seems unsupported by other differences ; in Thunberg’s type of Apocynum filiforme 
it is very stout,
