 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. PI. ? 



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.

LIN. SYST. Tridndria, Trigynia. Calyx of 2, rarely of 3

 are smaller than the other 2. Stamens inserted in the claws 

 of the petals, usually 3 in front of each of the smaller petals, 

 very rarely more. Ovarium sessile. Style very short, 3-parted ; 

 divisions spreadingly reflexed. Capsule 1 -celled, 3-valved, 3-
