5. T. sessilis, Lecomtc in Journ. de Bot. x. 229-285, t. 1. Tuber 

 1-^ in. in diam. Rhizome solitary, hairy, 2-3 lin. in diam. Peduncles 

 none or very short, not scaly. Scales of the involucre multiseriate, 

 glabrous, ovate, acute, outermost and innermost small, not more than 

 a line long, intermediate 4-5 lin. long. Flower-heads spherical, about 



1 in. in diam., bisexual ; receptacle subglobose, constricted at the base, 

 7-8 lin. in diam. Male flowers relatively very few, in one or more series 

 outside of the female flowers, destitute of a perianth (?), reduced to 

 flattened clavate bodies 2 J lin. long ; anther-cells 4-8, linear, more or 

 less curved, unequal in length, dehiscing longitudinally. Female flowers 

 very numerous, 1-2 lin. long; perianth tubular, inflated, 4-5-lobed; 

 lobes deltoid, obtuse ; style clavate, papillose, about as long as the 

 perianth ; ovary linear, almost equalling the perianth ; ovule none, ] , 



2 or 3 free embryo-sacs being formed in the tissue of the carpel. Fruit 

 an achene crowned by the withered perianth. Seed without integument, 

 reduced to albumen surrounding a nearly spherical embryo, seated in 

 the centre of the upper part of the albumen.

Descripti(m compiled from Professor Lccomte's account of tlie plant, which is 

 evidently allied to T. nuffolensi.s, Hemsl., differing in the snniller flower-heads, 

 relatively small male llowers and the much more highly develoi)ed perianth of the 

 female flowers. 



6. T. angolensis, Jfentsl. Tuber not seen. Rhizomes branching, 

 3-5 lin. thick, densely tomentose, bearing numerous, almost crowded 

 flower-heads. Volva distinct, truncate or obscurely lobed. Peduncles 

 J-l| in. long, numerous, contiguous, constricted below the flower-heads ; 

 scales thick, ovate, 3-4 lin. long, subacute, very hairy on the covered 

 surfaces. Scales of the involucre similar but larger and glabrous on 

 both sides, longest 9-10 lin. long, intermediate scarious, mostly very 

 broad at the base, abruptly acute, innermost very small, 1-3-toothed at 

 the apex. Flower-heads spherical, |-lj in. in diam., bisexual, "rose- 

 coloured " {Monteiro) ; receptacle hemispherical or almost spherical by 

 constriction at the base. Male flowers in one or more circumferential 

 series, 2J-3^ lin. long. Perianth of usually 3 linear acute unequal 

 lobes, the free part \-2 lin. long, the longest about half the length of 

 the staminal column. Anther-cells 1-5. Female flowers very numerous, 

 1-1-| lin. long ; ovary longer than the style. — "• T. sainjiuneaf Monteiro,

It is quite probable that this may ))rovc to be the same as T. sess-ilis, Lccomte, in 

 spite of slight described differences in both mule and female flowers. The length of 

 jteduncle varies considerably on the same rhizome and contiguous flower-heads. 

 Allhough tubers are wanting, Monteiro's specimens are otherwise excellent and 

 uuiple in other respects and they are preserved in iilcohol.
