Male flowers about 50 to the head, 5-6 lin. long, interspersed with 
subulate bracteoles 1-1} lin. long; perianth-tube about 2 lin. long ; 
lobes usually 4, linear, about as long as the tube, erect, equal or 
unequal in length ; staminal column clavate; anther-cells 2-3 lin. long, 
dehiscing longitudinally. Female flowers very numerous, very slender, 
1-1} lin. long; ovary about as long as the exserted style, usually dis- 
tinctly 3-toothed, teeth acute, unequal.

Perhaps not specifically distinct from 7’. sanguinea, but the larger flower-heads 
with relatively longer involucral scales, the more fully developed perianth of the 
male flowers and other slight differences seem to justify separation. 
3. T. ugandensis, Hemsi. Tuber and rhizomes wanting. Volva 
about } in. deep, almost truncate or irregularly lobed; lobes broad, 
rounded. Peduncles }-24 in. long, slender ; scales thick, ovate, 3-5 lin. 
long, lower ones somewhat obtuse, keeled, slightly hairy at the base 
inside. Scales of the involucre continuous with those of the peduncles, 
similar but larger and very acute, longest 1 in., obscurely serrulate. 
Flower-heads unisexual ; male 3in., female 14 in. in diam., globose or 
subglobose; receptacle 4-9 lin. in diam, Male flowers 40-50 in a head, 
interspersed with filiform bracteoles, 6-8 lin. long; perianth more or 
less adnate to the staminal column; lobes 3, or rarely 4, linear, acute, 
of unequal length and attachment ; staminal column only slightly 
overtopping the longest perianth-lobes ; anthers usually 5, confluent, 
dehiscing longitudinally. Female flowers exceedingly numerous, some- 
times more than 10,00U in a head, 1-2 lin. long, but mostly about 14 
lin. long ; perianth about twice as long as the free style ;-tube almost 
capillary, but relatively thick and fleshy in the outermost flowers, which 
are nearly as long as the innermost scales of the involucre ; limb obscurely 
dentate; bracteoles none.—‘“ 7’. sanguinea,’ M. T. Dawe, Report on a 
Botanical Mission through the forest districts of Buddu and the White 
Nile Province of Uganda, 1906, 55.

Excellent specimens of inflorescences in alcohol. 
Careful counting of the number of female flowers in a head of average size gave 
a total of 10,808; but, judging from superficial comparisons, this number is at least 
equalled in other species. 
4. 'T. elegans, Hemsl. Tuber absent. Rhizomes cylindrical, 
about 3 lin. in diam., pubescent. Volva well developed, with broad 
wregular lobes, Peduncles 3-1} in. long; scales thick, glabrous on 
both sides, lower ones obtuse. Scales of the involucre lanceolate or 
oblong-lanceolate, the longest 1-1} in. long, acuminate, very acute, 
intermediate, thin, narrow-oblong or almost linear, innermost quite 
small. Flower-heads ovoid, unisexual; male only present, 1-1} in. 
long, 5-10 lin. in diam. ; receptacle convex, 3-5 lin. in diam. Male 
lowers 50, or more, in a head, interspersed with smail bracteoles, 7-9 
lin, long; perianth more or less adnate to about the middle of the 
stamina] column ; lobes usually 3, linear, acute, unequal, 1-2 lin, long. 
Stammal column clavate; anther-cells elongated, subequal.
