petals. Ovary half-inferior, 2-celled ; ovule 1 in each cell ; 

 style cylindrical, simple ; stigma obtnse. Fruit a somewhat

 1-celled, 1-seeded. Seed without albumen. 



Water plants, floating on lakes and ponds. — T. hispinosa, Eoxb., occurs 

 at Natal, where its singularly-formed fruits, which are full of farinaceous 

 substance, are eaten by the Zulu Kaffirs. The submerged leaves are opposite, 

 pinnatisect, with vei'y narrow lobes, the floating crowded in a rosulate 

 cluster, petioled, rhomboid, toothed, the petioles swollen and hollow in the 

 middle, forming floats ; flowers axillary, solitary. The black-brown oval 

 nut is crowned with 2 straight barbed horns ; and its either side, in the spe- 

 cimens I have received, is curiously furnished with prominences arranged 

 like the features of a diabolical face ; a long, hooked nose, a pair of peering 

 eyes, and a pursed-up mouth. Specimens sent to me bv Mr. Sanderson, of 

 Natal.
