A petiole of Kalanchoe tubiflora<\/em> is elongated and a leaf blade is reduced at the tip. Can you explain the curious morphology of the leaf blade?<\/p>\n

Protruded regions are leaf lobes and plantlets are formed on sinuses. When plantlets become bigger, sinus tissue elongate to subtend a plantlet.<\/p>\n

Garc\u00eas et al. (2007) described development of leaf plantlet of Kalanchoe daigremontiana<\/em>. At first, tissue protrude as a dome and then becomes to be resemble to globular stage embryo as well as shoot apex. Then, the tissue becomes similar to a hart-shaped embryo. However, differently from an embryo, adventitious roots are formed. Vascular bundles are formed independent from leaf vasculature. The authors interpret that the development of leaf plantlet is a mixture of embryo and shoot development.<\/p>\n
