I hope that some Australian botanist will be able to study on the spot the flowering of this species and the development of the fruit, which has several interesting points still unsolved (e. g. the fate of the coats of the ovule). Posidonia sp. I found at Carnarvon, besides the typical broad-leaved P. australis, some narrower leaves like those of a broad-leaved Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dansk botanisk forening.
