96 POLYGALE (Harv.) [Muraltia. 
of John von Muralt, a Swiss botanist. The genus naturally divides itself, as pointed 
out by Turczaninow, into two subgenera ; the first (EUMURALTIA) distinguished by 
subsessile flowers, and with few exceptions by fascicled leaves and long-horned cap- 
sules ; the second (PsiLocLapus) by manifestly pedicillate flowers, solitary leaves, 
90 emarginate or ey 4-tubercled capsules.
