Plate 24. Structural features of the raphide system in Vitis vulpina. 1. Raphide packet in situ in a leaf. Note the elongate nature of the packet and the cell wall surrounding it. 2. Two isolated packets showing their elongate nature and a large “hole” in one of them. 3. Two isolated packets showing narrow ends and wide centers. 4. Fractured packet showing the disposition of the raphide crystals contained within. 5. TEM showing the twin nature of the calcium oxalate raphides. Adapted from Arnott and Webb, 2000; Webb and Arnott, 1995. 58 Tex. J. Micros. 38: , 2007
Plate 25. Calcium oxalate crystal twins isolated from Vitis vulpina. 1. Isolated raphide crystals without their crystal matrix. Note also the three isolated druses. Each group of raphides contains about 120-200 twin crystals. 2. Raphide crystals spread out by the addition of water to several packets. Note that there are several small initials seen on the surface of the group of raphides. 3- 4. Isolated mature raphides and raphide initials. Several of the initials are intermediate in size. 4. Inset shows two intermediatesized initials. Two isolated mature raphides show the narrow and the sharp pointed ends of the twins. 5. Enlarged view of several raphide initials. 6. Two raphide initials with holes between the individual twins. Adapted from Arnott and Webb, 2000. Tex. J. Micros. 38: , 2007 59
