 Add ''part_of shoot apex''. This relation is currently there for leaf primordium, but should apply to all phyllome primordia.
-Add ''develops_from peripheral zone (PO:0000225), if this is appropriate for all plant. For angiosperms: ''"The SAM consists of two zones.

 Comment:  Root primordia may arise from pericycle cells (PO:0025261), as in most seed plants, cells of an endodermis (PO:0000252), as in ferns, or from cells on a shoot axis (PO:0025029), in the case of basal root primordia (PO:id) and shoot-borne root primordia (PO:id). Transition from root primordium to root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147).

 comment: A lateral root primordium generally develop from pericycle cells (PO:0025261), but cells of an endodermis (PO:0000252) may also participate in the formation of a lateral root primordium in some species, and in ferns lateral root primordia develop from the endodermis. Transition from lateral root primordium to lateral root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147), which can occur before the lateral root penetrates the exterior of the parent root.

	A possible exception to this is for Asteraceae, in which each floret arises as a buldge which might technically be an apical meristem, but is often called a primordium. We may want to add a term for '''disk flower primordium'''. -''DWS thought it was better to call this a floral apical meristem, and not add special term for disk florets.''
