Zeyher’s plant was quoted by Harvey under B. filiforme, Harv., but is not the 
plant he figured and described under that name. According to an excellent 
drawing of B. Zeyheri in the Kew Herbarium, made from a plant introduced by 
Bowie in 1823, it flowered at Kew in August, 1824. 
28. B. filiforme (Harv. Thes. Cap. i. 58, t. 93); tuber flattened, 
2-2} in. in diam., with 1 or more stems, branching at the base, 
erect, 6-8 in. high, minutely puberulous, with internodes up to 2 in. 
long; leaves spreading, sometimes undeveloped at the time of 
flowering, 14-6 lin. long, 4-1 lin. broad, linear or narrowly linear- 
lanceolate, acute or obtuse, tapering into a short petiole at the base, 
longitudinally folded, sometimes undulated at the margins, glabrous 
above, minutely puberulous beneath ; flowers 2-6 together at the 
nodes or forks of the branches ; pedicels 4-3 lin. long ; sepals 3 lin. 
long, lanceolate, acuminate, and like the pedicels puberulous ; 
corolla cage-like, lobed nearly to the base, with the lobes connate at 
the tips, “‘ brownish-purple” (Mrs. Barber) ; united part flattish or 
saucer-shaped, scarcely } lin. long, shorter than the corona, glabrous 
outside and within ; lobes 2-2} lin. long, linear-filiform from a 
deltoid-ovate base 3 lin. broad, with a few exceedingly minute 
papilla-like hairs on the back, otherwise glabrous ; outer corona- 
lobes } lin. long, apparently erect and equalling or slightly over- 
topping the staminal column, divided to the middle or beyond into 
2 subparallel linear or subulate teeth, sparsely ciliate with very 
minute or papilla-like hairs ; inner corona-lobes } lin. long, linear or 
narrowly deltoid-linear, obtuse, closely incumbent on the backs of 
the anthers and exceeding them, with the tips incurved over their 
apex, very minutely papillate-puberulous at their base on the back.
