T’. ambigua, however, are connate throughout in a narrow funnel- 
shaped tube with only the stigmas free. The known Tropical 
African localities of 7. ambigua are as follows :—British East 
Africa: Kibwezi, Kaessner, 706. German East Africa: Rosallo 
Thal, Holst, 3861 ; Kerematonto, 1700 ft., Engler, 3347. Portu- 
guese East Africa: Moramballa, 3500 “ft, Kirk ; Gazaland ; 
Chirinda Forest, 3700-4000 ft. , Swynnerton, 446, 795. The known 
P. ambigua, s. “pee the species described as 7’. anomala is 
readily cieickel by its pubescence and diifors further from its 
ally in having the style-column swollen into a pyriform or sub-globose 
mass quite as large as the ovary when in flower. In this character 
T’. anomala therefore agrees with the Madagascar plant described 
by Baillon (Etud. Euphorb., 466, t. 21) as Sphaerostylis Tulasneana, 
This genus had ety Some which has been doubtfully maintained by 
Mueller (DC. Prodr., xv., 2, 768) and by Bentham an ooker 
(Gen. Plant., iii., 327), as described by Mueller differs from T'ragia 
in having a central staminal column, 2-partite stigmas and a globose 
inflated style-column. As described by Baillon the stigmas are said 
to be channelled but not said to be 2-partite. The description given 
of the androecium both by Baillon and by Mueller is such as might 
apply to that of the androecium of most of the Tragias of the group 
T. anomala resembles, which have extremely short or quite 
ohaslebe filaments ; Baillon’s description and figure of the style- 
column and stigmas of Sphaerostylis Tulasneana accord very 
closely with the conditions met with in 7. anomala. It appears 
probable therefore that sphamoriyt Tulasneana may be only a 
rather distinct species of gk agia
