Each specimen described is actually a letter of the English alphabet, with juvenile and adult variants being lower case and upper case respectively. That is:
Specimen 1: Strong similarities between juvenile and adult specimens - the main distinguishing feature for the fully grown specimen is its upper bough reaches the same height as its trunk.
Specimen 2: Starkly different from specimen 1, this specimen metamorphoses completely between seedling and adult. It almost doubles in height, acquires a secondary root, and its hoop-shaped bough becomes more rigid and is lifted into its centre.
Specimen 3: This interesting specimen raises the level of its canopy with respect to its trunk as it grows without significantly gaining height - the most mature of these have branches only at the very top of their trunk.
Specimen 4: Apart from growing in size vertically and becoming less supple, this specimen sprouts a secondary trunk from its secondary root, which reaches the same height as the primary.
Specimen 5: The seedling of this specimen is most noted for the brilliant blossom that it delicately suspends above its stem. As it ages this blossom is lost, and it becomes a particularly plain, but rather tall, reed.
Specimen 6a/b: The recurve shape is characteristic in these vines, partly because it is shared between the juveniles and adults of the species. The fully grown specimen is significantly larger, perhaps twice the size of the juvenile.
