33. sambftcina, Linn. Differs from /. squalens in its 

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

 The outer segms. are colored and veined with claret 

 not lilac-purple; inner segms. emarginate. Late May. 

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

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

 probably represents /. sambucina. Both forms are very 

 likely hybrids between 7. pallida and 7. variegata.) 

 Tall and handsome. 



34. squalens, Linn. Lvs. glaucous, 1-1 M ft. long: 

 st. 2-3 ft. high, much branched and many-fld.: spathe- 

 valves subscarious: outer segms. obovate-cuneate, 

 upper part plain lilac-purple; claw yellow, veined with 

 lilac; beard yellow; inner segms. as large, obovate, 

 dull lilac and yellow, or brownish and yellow. Cent. 

 Eu. to Caucasus. B.M. 787. (See note under 7. 

 sambucina.) J.H. III. 48:481. Many of the German 

 irises of cultivators belong to this form. Var. Jac- 

 quesiana, Hort. Outer segms. dark red-violet, yellow 

 at base; inner segms. tawny yellow. Late. One of the 

 best.
