 mental vars. the most distinct and decorative is var. 

 lacini^ta, Loud. (var. fllicifnlia, Hort., var. asplenlfblin , 

 Hort.),with narrow, pinnately cut Ifts.; very effective 

 as a single specimen ou the lavn ; remains usually 

 slirubby. Var. monophylla, Hort., has the Ivs. simple or 

 :i-foliolate. Var. pendula.Hort., has pendulous branches. 

 Var. praeparturiens, Hort., is a shrubby var., producing 

 rather small, thin-shelled nuts on very young plants. 

 Var. Bartheriina, Hort. (var. eloiif/afa, Ilort.). Nut

 S.S. 7:335. — The typical form has narrower, more gla- 

 brous Ivs. and smaller frs., while 

 var. major, Torr., the western form, 

 is of more vigorotis growth, has 

 broader, more coarsely serrate and 

 more pubescent Ivs. and larger, 

 less thick-walled nuts. S.S. 7:336. 

 Probably J. longirostris, Carr. (R.
