Gross Morphology of Cladodes.

(A) and (B) Generating position of a lateral shoot in Arabidopsis (A) and a cladode of A. asparagoides (B). Note that the cladode arises at the axil of the scale leaf. cl, cladode; l, leaf; ls, lateral stem; sl, scale leaf; st, stem.

(C) A shoot of A. asparagoides.

(D) A cladode of A. asparagoides.

(E) A scale leaf of A. asparagoides.

(F) Simplified phylogenetic relationship of cladode morphology in the genus Asparagus based on Fukuda et al. (2005).

Bars = 1 cm in (C) and (D) and 1 mm in (E).
