171. Drosera bulbigena A. Morrison in Transact. and Proc. Bot. Soc. 
Edinburgh, XXII (1905), p. 417. ; 
Stem filiform terminating in a few-flowerd raceme, rootstock forming 
a bulb; stem-leaves with a lunar-peltate lamina, those at base reduced 
to scales, Sepals ovate, with long cilia-like teeth, glabrous, half as long 
as petals. Styles in two, sometimes three, tufts of subacute filaments 
spreading from the base, or occasionally also dividing higher up into two 
or three branches. 
. Plant 3—6 cm in height above ground, quite glabrous, with a root- 
stock of 4 em or less covered with pale brown fibrous remains of the 
old axis and sending out a few long horizontal processes close to the 
surface of the ground; at the base terminating in a bulb covered with 
thick dark brown scales, or forming a series of bulbs developed in 
succession downwards. Stem erect, slender, flexuose, its leaves on 
slender petioles of 2—3 mm dilated at the base but without stipules, 
lamina truncate orbicular 2 mm or less in diameter and reflexed on top 
of petiole which is attached close to the truncate margin, one or two of 
the lowermost leaves reduced in size, and 1—3 lanceolate scales at the 
base. Raceme unilateral on a peduncle of 1 cm or more above last leaf, 
pedicels somewhat longer than sepals which are 2—3 mm including the 
teeth, ovate and glabrous; petals 4—6 mm ovate or obovate, obtuse, 
white; filaments dilated at the top, anther-cells distinct. The flowers 
vary in number from 1—6 in the raceme, and are mostly 5-merous, but 
the styles are only 2—3 in tufts of 6—12 slightly tapering filaments. 
Irregularities have, however, been noted, as a male 4-merous flower; an- 
other hermaphrodite and 4-merous, but with 3 styles; and one 8-merous 
showing 8 petals, but with the seventh sepal a short way down the 
pedicel, and the eighth, like a bract, still lower, while the seventh and 
eighth stamens are connate, and the styles are in two main divisions,- 
with numerous branches spreading from the base. The bracts are 
frequently absent and variable in size, lanceolate and more or less ciliate, 
or setaceous, sometimes in pairs. 
West Australia: Coolup, Murray River (R. Helms). Wet flats, 
Lower Canning River (A. Morrison). 
The affinity of this plant is clearly with Drosera Banksii R. Br., and 
D. myriantha Planch., not only in the important character of the style- 
branches, which are fewer than in any other. species of the cauline type 
of Drosera, but also in the general similarity of most of the othe 
characters, These three species by themselves form, by reason of their 
less divided styles, a small group connecting the long-stemmed species 
of the Ergaleium section with those of section Rorella, in most of which 
the styles are simple or few-branched.
