Roem. et Schultes, syst. 3. p. 200. A very obscure species, 

 and syn. in Rheed. mal. 10. t. 31. cited for this species is re- 

 ferrible to Porluldcca Meridiana.

N. B. Oldenlandia nudicaulis, Roth, nov. spec. p. 96. and 

 Old. maritima, exclusive perhaps of the synonyme of Lin., 

 differs from this genus in the flowers being of 4 distinct petals, 

 and in the want of stipulas ; they therefore even do not belong 

 to Rubmceae, but are probably Caryophyllaceous plants. 



Cult. The species are not worth cultivating, unless in bo- 

 tanic gardens. A very sandy soil suits them best, and cuttings 

 of the shrubby kinds will root in sand, under a hand-glass, or 

 by seeds. The annual kinds should be treated like other tender 

 annuals, by being raised on a hot-bed, and afterwards planted 

 ouf. All the species require a considerable degree of moisture.

LIN. SYST. Tetrdndria, Monogynia. Calyx with an obovate 

 tube ; teeth acute, separated by acute recesses while in flower,

 throat. Style shorter than the anthers, bifid at the apex. 

 Capsule globose, membranous, crowned by the teeth of the 

 calyx, 2-celled, dehiscing at the cells. Seeds innumerable, 

 small, half immersed in pits on the placentas, which are glo- 

 bose and stand on short pedicels. Erect, twiggy, glabrous, 

 branched herbs, with the habit of Asperula. Leaves op- 

 posite, linear, or linear-lanceolate. Stipulas joined to the 

 petioles, furnished with one or few bristles. Cymes terminal, 

 corymbose, or loosely spicate.

bose ; lobes of corolla oval, mucronate. Tj . S. Native of
