Eriocaulon| XXVI. ERIOCAULACE, 101 
floral bracts glabrous, oblanceolate-spathulate, the outer obtuse, 
the inner becoming acute; female flowers on a short glabrous 
pedicel, sepals obovate, boat-shaped, acute, slightly keeled with a 
few short white hairs on the upper part of the back, unequal, the 
outermost the largest; petals close above the sepals, fuscous, 
narrow-linear, tapering downwards, apex blunt, irregular, often 
bearing a few very short hairs, but no glands; ovary trigastrous, 
style with three filiform branches as long as the petals; seeds pale 
brown, striolate; male flowers on glabrous pedicels, sepals linear, 
free or unequally connate below, apex blunt or irregularly broken, 
often with a few short white hairs, pedestal above,the calyx about 
3 to } length of the sepals; petals rudimentary, ovate-triangular ; 
stamens 6, anthers black. 
Plants said to be completely submerged, flowering and fruiting 
beneath the surface, 8 to 14 in. high. Leaves 2 to 4 in. in 
length by about 4 line greatest width; scapes 6 to 13 in. long; 
sheath 2 to 24 in. Mature flower-heads 23 to 32 lines across ; 
involucral bracts 3 to 1 by 3 to 4 line; floral bracts 1 by nearly 
4 line. Stalk of female flowers 3 line long, sepals = to 1 line, 
petals about 1 line; stalk of male flower i line long, sepals 
scarcely $ line by 4, to } line, the broader ones concave. 
Near the last species but distinguished by its submerged habit, 
very narrow leaves, black heads, etc. 
Hvuitia.—Here and there by a large pond near the banks of the 
river Mupanda. A few poor specimens collected during flight ; Feb. 
1860. No, 2456. Somewhat rare in gently flowing rather deep 
streams between Lopollo and Nene, flowering in autumn. Produces 
both flower and fruit beneath the water; end of April 1860. All 
the specimens seen grew at the bottom of a stream 2 to 3 ft. deep, 
and the plant thus seems to flower and fruit beneath the surface. On 
the muddy bottom of slowly flowing streams between Humpata and 
Lopollo, in one place only, but plentiful there ; end of April 1860. 
No. 2457. 
9. E. stoloniferum Welw. ms. in herb. 
A glabrous perennial stoloniferous submerged herb; leaves 
radical, long, linear-tapering, acute, a very bright shining green ; 
scapes solitary or few, far exceeding the leaves, multiangular 
(7- or 8-), flattened when dried; sheath much shorter than the 
leaves, broad, with a bluntly bifid apex; flower-heads subfuscous, 
transversely elliptical, moncecious, flowers trimerous, the inner 
often viviparous ; receptacle broadly truncately conical, glabrous ; 
involucral bracts whitish, glabrous, spathulate-obovate, very 
blunt; floral bracts fuscous, glabrous, oblong-spathulate to 
spathulate, blunt; female flowers shortly pedicellate ; sepals 
rhomboideo-obovate, concave, glabrous, fuscous; petals close 
above sepals, cuneate to oblong-cuneate, the apex and upper 
surface just below it tomentose, with a black subapical gland ; 
ovary trigastrous, the 3 filiform stigmas exceeding the petals ; 
seed yellowish-brown, spherico-pyriform, hilum brown, surface 
faintly striolate; male flowers with a short glabrous pedicel ;
