Metaphloem sieve elements ofLycopodium clavatumL. are elongated cells with steeply inclined end walls. Numerous pores of small diameter are present on all contact walls between sieve elements. At maturity, these elements lack a normal-looking nucleus, and their protoplast is partially degenerated. ...

A new series of methyl and ethyl w-(6-phenanthridinyl) alkanoates is easily synthesised from the acid chloride-esters ROCO(CH 2 ) n COCl (n=0,3 to 8; R=Me or Et). Reaction of these with o-aminobiphenyl leads to the expected amide-esters which are cyclised to phenanthridines ...
