_ This plant is evidently variable in the colour of its flowers, as, according to 
Wood's 5369, they are greenish-brown, in 5383 yellow and white, and in 5760 
green; the corona-lobes also vary. In the size, shape and structure of its flowers 
f is almost identical with 9. bidens, H. Meyer, but it is a stouter and taller 
plant, with shorter peduncles and pedicels, and more numerous flowers in an 
umbel, and is much more pubescent than 8. bidens. Krook, 794a, has been 
erroneously distributed with the number 7945 and named S. carinatum. 
15. 8. Wallacei (Schlechter in Journ. Bot. 1895, 268); plant 
dwarf, slightly branching from the base; stems erect, densely leafy, 
unifariously villous ; leaves exceeding the internodes, 3-1 in. long, 
2-4 lin, broad, linear or linear-lanceolate, obtuse, subtruncate- 
hastate at the base, with revolute margins, scabrid-pilose above, 
glabrous beneath; umbels lateral at the nodes, few-flowered ; 
pedunele as long as the leaves, erect, pilose ; pedicels unequal, 3-4 
times as long as the flowers, pilose ; sepals half as long as the corolla, 
lanceolate, acute, pilose ; corolla-lobes erectly-spreading, 3 lin. long, 
12 lin, broad, ovate-oblong, obtuse, with reflexed margins, glabrous 
on both sides; corona-lobes ovate, 3-toothed at the apex, with an 
appendage on the inner face; lateral teeth erect, much larger than 
the minute inconspicuous middle tooth; appendage deeply bifid, 
with erect obtuse segments not exceeding the lateral teeth of the 
lobe; anther-appendages ovate, very obtuse, inflexed on the style- 
apex; caudicles attached to the middle of the ovoid pollen-masses.

16. S. bidens (E. Meyer, Comm, 220) ; tuber fusiform, producing 
1-3 simple or branched stems 4-9 in. high, pubescent with rather 
minute curved hairs; internodes 2-14 lin. long ; leaves ascending, 
alternate, opposite or 3-4 in a whorl, often on the same stem, mostly 
1-22 in. long, 1-2 lin. broad, linear, with revolute margins, obtuse 
or acute, cuneate to subhastate at the base, minutely scabrous- 
pubescent above and on the midrib beneath ; petiole 1-12 lin. long; 
umbels 3-6 to a stem, usually subcorymbose, pedunculate, 2-6 
flowered ; peduncles usually 6-19 lin. long or the uppermost less, 
puberulous; bracts 1-1} lin. long, subulate ; pedicels unequal, 
slender, 3-9 lin. long, puberulous ; sepals 2 lin, long, 3 lin. broad at 
the base, thence tapering to an acute point, pubescent ; corolla-lobes 
11-21 lin, long, 7-1} lin. broad, oblong, acute, suberect, replicate, 
with the tips incurved and the apex itself shortly recurved, quite 
glabrous or with a very few minute hairs on the back, apparently 
brownish; corona-lobes shortly overtopping the style-apex, 1-14 hin. 
long, 3-2 lin. broad, ovate or ovate-oblong, often narrowed into 4 
short linear-oblong upper part, bifid or emarginate at the rather b 
apex, with an appendage and 2 parallel keels on the inner face;
