Orpen XX. BALSAMINACEA Dumort. Anal. Fam. 46. 
Succulent herbaceous planis with bland colorless juice, sim- 
ple opposite or alternate leaves without stipules and irregular 
axillary flowers. Sepals 5, imbricate in the bud, deciduous, 
the two upper usually connate, the lowest spurred ro gibbous. 
Petals hypogynous, usually 4, and unitedby pairs, rarely 5
