Three independent patterns of vein formation in Cyperus involucratus Rottb. were identified based on rare spontaneous interruptions of scape vein development. A number of developmental anomalies of vascular bundles in Cyperus involucratus Rottb. were identified and they include "turnabout", "absent", "twins", "doublet", amphivasal and various stages of "arrested". These were used to develop a computer program to explain the three vasculature patterns of the scape of (a) ordered deployment of vascular bundles, (b) arrangement of tissues within vascular bundles and (c) orientation of vascular bundles with respect to stem edge. The computer model is a cell-by-cell determination of cell types and facet states.
基于花葶叶脉发育中罕见的自发中断，确定了风车草叶脉形成的三种独立模式。在风车草中发现了许多维管束发育异常情况，包括“反转”“缺失”“孪生”“双生”、周木型以及不同阶段的“停滞”。利用这些情况开发了一个计算机程序，以解释花葶的三种脉管系统模式：(a) 维管束的有序排列，(b) 维管束内组织的排列，以及 (c) 维管束相对于茎边缘的方向。该计算机模型是对细胞类型和小面状态进行逐个细胞的确定。
