%X Procedures for the preparation of perspective drawings from serial sections of shoot apices and similar small structures are described, and the properties of the projection are critically examined. The procedures have potential value for morphogenetic studies, and examples are given for shoot apices of flax and lupin. For lupin it is shown that the folioles arise in an oblique circle at the top of the emerging petiole. After the median member, they appear in pairs at unit plastochron intervals.
