late ovati, obtusi, apice inflexi, glabri. Petala calyce duplo longiora. Stamina 5. 

 Stylus 3-fidus. Semina tuberculata. 



A small succulent herb, branching at the base, with branches 2-3 in. long, glabrous, 

 with the exception of the tufts of long white hairs in the axils of the leaves and around 

 the flowers. Leaves 1^-3 lin. long, -|-§ lin. broad, flattened, linear-oblong or oblong- 

 lanceolate, obtuse, tapering at the base into a short petiole, glabrous. Flowers small. 

 Sepals f lin. long, rather more than \ lin. broad, broadly ovate, obtuse, indexed at the 

 apex, concave, not keeled on the back, glabrous. Petals lij lin. long, only seen in a 

 withered state, apparently obtuse. Stamens 5, shorter than the petals. Style filiform,

 tuberculate, the tubercles on the sides very much larger than those on the back, black. 



Ireng Valley, McConnell & Quelcli, 237. 



Allied to Portulaca parvula, A. Gray, but differing in its shorter leaves, fewer 

 stamens, and larger and more coarsely tuberculate seeds.

Ceusia Planchoniana, Engl. (?) in Mart. El. Bras. sii. pt. i. p. 131. 



Ivukenaam River, McConnell & Quelcli, 130. 



I am doubtful of my identification of this plant, and it may prove to be a new species, 

 but the specimen only consists of three flowers and two leaves, all detached. They agree 

 fairly well with the flowers and leaves of C. Planchoniana, with the exception that the 

 leaves are rather more obtuse and have stouter petioles.
