 Hab. On hills, near Eio Janeiro. 



The seeds, in the single specimen gathered, are obscurely muricate ; 

 while in the North American plant they are strongly muricate, as in 

 the figure of Gaertner above cited.

Portulaca villosa, Cham, in Linnsea, 6, p. 565; Walp. Repert. 2, p. 234. 



Hab. Sandwich Islands : on Diamond Hill, and on the plains near 

 Ewa, Oahu. 



"Flowers fine purple;" the petals 5 or 6 lines long, rather longer 

 than the sepals. It appears scarcely different from P. pilosa, except 

 in the seeds, which are smooth, or, when considerably magnified, 

 minutely marked with sinuous areolations.
