33. samb&cina, Linn. Differs from /. squalens in its 

 less robust habit, narrower segms. and elder-like odor.

 not hlac-purple; inner segms. emarginate. Lat« May. 

 Cent. Eu. B.M. 187. (According to Dykes this figure 

 is probably /. squalens, while plate 787, 7. squalens, 

 probablj' represents I. sambucina. Both forms are very 

 likely hybrids between I. pallida and /. variegaia.) —
