Saxifragaceae
From Natural History of Southeast Alaska
Family: Saxifragaceae
Group: Vascular Plant, Species
Scientific Name | Common Name | Summary |
---|---|---|
Chrysosplenium tetrandrum | Northern Golden Saxifrage | Collections in ARCTOS from northern Admiralty and Northeast Chichagof as well as near the border outside of Haines and Skagway. |
Heuchera glabra | Smooth Alumroot | Common wintergreen herb of cliffs, rock outcrops and rock walls. Collections in ARCTOS from across the region. (Though none mapped from Baranof Island.) |
Leptarrhena pyrolifolia | Leather-leaf Saxifrage | Collections in ARCTOS from across the region. |
Micranthes ferruginea | Alaska Saxifrage | Collections in ARCTOS from across the region. No collections mapped from Chichagof or Admiralty Islands, nor most of Prince of Wales. |
Micranthes foliolosa | Leafystem Saxifrage | Three collections in ARCTOS from Chilkat Mountains and near Juneau. It appears to be similar to Alaska Saxifrage (Micranthes ferruginea). |
Micranthes hieracifolia | Hawkweed-leaved Saxifrage | A 1937 collection from Mt. Roberts is the only one mapped in ARCTOS from the region. The nearest other collection appears to be from the mountains of Southwestern Yukon. |
Micranthes lyallii | Red-stem Saxifrage | Collections mapped in ARCTOS spanning the region, but significant gaps, including Baranof and Admiralty Islands, and the mainland between Cleveland Peninsula and Skagway. |
Micranthes nelsoniana | Heart-leaf Saxifrage | Collections in ARCTOS from across the region, though concentrated in the southern half, and the northern mainland. |
Micranthes nivalis | Alpine Saxifrage | Three collections in ARCTOS, one from Admiralty Island, one from the mainland near Wrangell, and another near Haines. |
Micranthes occidentalis | Western Saxifrage | Two collections in ARCTOS, one from the Taiya river near Haines, the other from Revillagigedo Island. |
Micranthes razshivinii | Alaska Saxifrage | No collections in ARCTOS from the region. Based on overall distribution of collections, this species seems unlikely to occur in Southeast Alaska. |
Micranthes reflexa | Reflexed Saxifrage | A single collection from Mendenhall Glacier is the only one in ARCTOS from the region. This species' overall distribution appears to primarily restricted to the continental side of the coast mountains. |
Micranthes tolmiei | Tolmie's Saxifrage | Several collections in ARCTOS from the eastern part of the region (mainland and near islands) as far north as Juneau area. |
Mitella nuda | Naked Mitrewort | No collections in ARCTOS from the region. Hulten has a single record mapped near Skagway. Records mapped in e-Flora BC are all from the continental side of the Coast Range at latitudes corresponding to Southeast Alaska. |
Mitella pentandra | Alpine Mitrewort | Collections in ARCTOS from across the region |
Mitella trifida | Three-tooth Mitrewort | The only record of this species from the region appears to be a 1979 collection from near Haines. This collection is hundreds of miles from the nearest other record mapped on e-Flora BC (well to the south and east, inland from Prince Rupert). Collection notes indicates many plants. Verification of the collection id is probably warranted given the outlying nature of this record. |
Saxifraga adscendens | Wedge-leaved Saxifrage | A few scattered collections from the region mapped in ARCTOS including Prince of Wales Island, Hecata Island, Chichagof Island and the mainland near Haines. Associated with limestone sites in the region? |
Saxifraga bracteata | Pygmy Saxifrage | Nearest mapped collection in ARCTOS is from Kayak Island a bit to the west of the region. Hulten includes a record from the vicinity of Yakobi Island. |
Saxifraga bronchialis | Yellowdot Saxifrage | Collections in ARCTOS from the northern mainland (Juneau and north). |
Saxifraga caespitosa | Tufted Saxifrage | A few collections in ARCTOS from near the northern border with British Columbia, but also from northern Prince of Wales Island and Coronation Island. |
Saxifraga cernua | Nodding Saxifrage | Three collections in ARCTOS, one from near Juneau, the other two approaching the border outside of Skagway. |
Saxifraga cherlerioides | Hulten shows an isolated collection from Juneau, but no collections in ARCTOS from anywhere close. | |
Saxifraga eschscholtzii | Cushion Saxifrage | No collections in ARCTOS mapped from the region, though this species has been photographed on mountains of Baranof Island. Hulten shows an isolated collection from near Haines. Refugial candidate? |
Saxifraga hyperborea | Pygmy Saxifrage | Collections in ARCTOS mostly from northern mainland, but also alpine sites on Admiralty, Baranof, and Revillagigedo Islands. |
Saxifraga mertensiana | Wood Saxifrage | Scattered collections mapped in ARCTOS from across the region. |
Saxifraga oppositifolia | Purple Mountain Saxifrage | Collections mapped in ARCTOS from southern islands and the mainland from Juneau north. |
Saxifraga rivularis | Weak Saxifrage | Taxonomic review needed. It appears this species probably does not occur in the region as such - it appears plants that had been called this from the region are now called Pygmy Saxifrage (Saxifraga hyperborea). FNA indicates only one subspecies of this species occurs in Alaska, and it appears to be one from the arctic. |
Saxifraga serpyllifolia | Thyme-leaved Saxifrage | No mapped collections in ARCTOS from the region. Hulten's map includes dots near the Taku River and White Pass that appear to be from within Southeast Alaska. |
Saxifraga tricuspidata | Three-toothed Saxifrage | Collections in ARCTOS mapped from the northern mainland as far south as Juneau. |
Tellima grandiflora | Fringecup | Collections in ARCTOS from across the region. |
Tiarella trifoliata | Foamflower | Many collections in ARCTOS from across the region. |
Tolmiea menziesii | Youth-on-age | Collections in ARCTOS primarily from the far southern part of the region (southern half of Prince of Wales and Revillagigedo Islands. Also an isolated 2014 collection from Taku River area (Hulten mapped a single isolated record from the Taku River area as well) |
