of South America, in the shady woods of Javita. Perhaps this 
plant ought to be removed from the genus. ex H. B. et Kunth, 
nov. gen. amer, 6. p. 80. The plant, according to Bonpland, 
has a quadrangular stem; opposite petiolate leaves; terminal 
dichotomous spikes ; a 5-parted calyx; a semi-5-cleft corolla; 
a short style, 2 stigmas, and a 1-celled, many-seeded capsule. 
Grove Claytonia. Pl. ? 
Cult.. The greater part of the species of Claytonia are very 
delicate little plants, especially those with tuberous roots: these 
grow best in a border of peat soil, and are increased by seeds, 
which sometimes ripen plentifully. The fibrous-rooted kinds, 
being all annual, the seeds of them only require to be sown in | 
the open border, in a rather moist shaded situation; and if they | 
are allowed to scatter their seeds, plants will rise every year in 
abundance.
