| In Florida, Prokelisia are present throughout the year feeding on the phloem and laying eggs into the adaxial surfaces of the leaves. |
| It possessed secondary xylem and secondary phloem, which were produced by a bifacial vascular cambium with ray and fusiform initials. |
| Within the pod wall vasculature, phloem companion cells also appear to differentiate transfer cell-like wall ingrowths. |
| Cytokinins were analysed in leaf extracts, leaf phloem exudate and in the shoot apical meristem at different times during floral transition. |
| The phloem of some stems also contains thick-walled, elongate fiber cells which are called bast fibers. |
| Potassium has the property of high phloem mobility and, as a result, of a high degree of reutilization by retranslocation via phloem. |
