| Popis: | Pollen of Gingidium montanum J. R. and G. Forst. has been compared with the pollen of Aciphylla squarrosa J. R. and G. Forst., Angelica sylvestris L., Anisotome latifolia Hook.f., Ligusticum scoticum L., and Peucedanum officinale L.—type species of genera to which the 11 species of Gingidium have been referred at various times. Ihe results support the opinion that the genus Gingidium should be revived. There are three pollen types within the genus, the largest group containing seven species, including G. montanum. A smaller group includes G. deltoideum, G. geniculatum, and G. rosaefolium; and G. filifolium is in a category of its own. This grouping docs not correspond exactly with that proposed by Dawson in 1961, who places G. geniculatum and G. rosaefolium in the G. montanum group and G. carnosulum, G. diversifolium, and G. filifolium in the group of G. deltoideum. These differences give grounds for suggesting that the genus Gingidium is not yet clearly defined and that a reexamination of the group is ne... |
