Male flowers about 50 to the head, 5-0 lin. long, interspersed with 

 subulate bracteoles 1-1 J 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-;i lin. long, 

 dehiscing longitudinally. Female flowers very numerous, very slender, 

 1-1 i lin. long; ovary about as long as the exserted style, usually dis- 

 tinctly o-toothed, teeth acute, unequal.

Perhaps not spccirtcally distinct from T. sanyuuica, but the larger flower-heads 

 with relatively longer involucral scales, the more fully developed perianth of the 

 male flowers and otlier slight differences seem to justify separation. 



3. T. ugandensiSy Ilemsl. Tuber and rhizomes wanting. Volva 

 about J in. deep, almost truncate or irregularly lobed ; lobes broad, 

 rounded. Peduncles J-2J 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 fin., female Ih in. in diam., globose or 

 subglobose; receptacle 4-0 lin. in diam. Male flowers 40-50 in a head, 

 interspersed with filiform bracteoles, (1-8 lin. long; perianth more or 

 less adnate to the staminal column ; lobes o, 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 10,000 in a head, 1-2 lin. long, but mostly about Ij 

 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. — " 2\ sanguinea," M. T. Dawe, Report on a

Excellent specimens of intioroscenees 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, tliis 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 

 irregular lobes. Peduncles i-lj- in. long ; scales thick, glabrous on 

 both sides, lower ones obtuse. Scales of the involucre lanceolate or 

 oblong-lanceolate, the longest 1-lJ in. long, acuminate, very acute, 

 intermediate, thin, narrow-oblong or almost linear, innermost quite 

 small. Flower-heads ovoid, unisexual; male only present, 1-1 1 in. 

 long, 5-10 lin. in diam.; receptacle convex, 3-5 lin. in diam. Male 

 flowers 50, or more, in a head, interspersed with small bracteoles, 7-1) 

 lin. long; perianth more or less adnate to about the middle ol the 

 staminal column ; lobes usually 3, linear, acute, unequal, 1-2 lin. long. 

 Stammal column clavate; anther-cells elongated, subequal.
