Family 64. BALSAMINACEAE Lindl. Nat. Syst. Ed. 2, 138. 1836. 



JEWEL-WEED FAMILY. 



Succulent herbs, with alternate thin, simple dentate petioled leaves and showy 

 very irregular axillary somewhat clustered flowers. Sepals 3, the 2 lateral ones 

 small, green, nerved, the posterior one large, petaloid, saccate, spurred. Petals 5, 

 or 3 with 2 of them 2-cleft into dissimilar lobes. Stamens 5, short; filaments 

 appendaged by scales on their inner side and more or less united ; anthers coherent 

 or connivent. Ovary oblong, 5-celled ; style very short, or none ; stigma 5-toothed 

 or 5-lobed ; ovules several in each cell. Fruit in the following genus an oblong or 

 linear capsule, elastically dehiscent into 5 spirally coiled valves, expelling the 

 oblong ridged seeds. Endosperm none; embryo nearly straight; cotyledons flat. 

 Later flowers small, cleistogamous, apetalous. 



About 220 species, mostly natives of tropical Asia. The family consists of the following genus 

 and the monotypic Asiatic Hydrocera, differing from Impatient in its indehiscent 4-s-seeded berry. 

 In our first edition it was placed at the end of the order SAPINDALES, but is here grouped in the 

 GERANIALES.

 waste grounds in Pennsylvania. It is native of southern Asia.
