Remarks, Affinities, &c. 

 ( Only one other species is known in this genus, P. cytisoides, Wight 

 1 and Arn. , a plant of the tropical eastern Himalayas. 

 J Annual. Next to T. hamosa, Linn., a plant of Nile-land, Egypt, 

 \ and south Africa. 



i Both allied to L. Oarcini, DC, a plant of Nile-land, Persia, and 

 < Scindh. Those three species diverge so much from the generic 

 ' character as to form a distinct subgenus Ononidium. 



c The solitary axillary flowers are unusual in the section Brissonia, to 



\ which it belongs. 



r A trifoliolate species allied to T. lappacea, DC. from Nubia, and 



I T. Stocksii, Boiss. and T. spartea, DC from Beloochistan and 



l Persia respectively. 



( Probably nearest 0. Kirkii, S. Moore, an east tropical African species 



I reaching Somali-land. 



( One of the Hedysareae ; its generic alliance is with Ormocarpum, and 



\ some south American genera. 



Differs in important points from the generic character. 

 J Has affinity with A. abyssinica, Hochst. of Abyssinia and A. 

 \ nubica, Benth., a plant of Nubia and Arabia. 

 / Near A. arabica, Willd., an Arabian species, and A. Wightii, Baker 

 l of the Indian Peninsula. 



f Second species of the genus, differing markedly in its gynaeceal 

 I characters from the generic type. 



J Species of a genus only elsewhere represented by a species in Angola 

 \ and one in central Africa. 

 Unique in the family for its arboreous habit. 



Allied to the south African B. geranioides, Hook. fil. 



T. microptera, Fenzl. and T. echinata, Ait. south African species, 

 are nearest allies. 



Allied to Bupleurum. 

 ( Annual. Has near alliance with 0. dicholomum, Benth. and Hook. 

 \ from Marocco. 



Annual. 



J- These species entail some modification in the generic description. 

 Allied to Dirichletia. 



Curious fruit. Perhaps not of this genus. 



Allied to E. Wallichii, Kurz, from Tenasserim and Nicobar. 

 t Close to M. luteola, Del. from Nile-land. The capsular fruit is 

 \ peculiar in the genus.
