About This Book

A concise field manual that surveys the alpine and subalpine plants encountered along the Canadian Rockies and the Selkirks accessible by the trans-mountain railway, emphasizing distinct regional assemblages and plant adaptations to differences in moisture and exposure. Species are arranged by botanical families with general keys to families and genera; treatments include ferns, conifers, shrubs and the majority of herbaceous flowering plants while excluding grasses, sedges, and willows. Descriptions are accompanied by plates, watercolour illustrations and photographs, and the text relates local taxa to comparable mountain floras while noting characteristic species, habitats and elevational ranges.

Araceæ
Arum Family

Smooth perennial herbs with tuberous or corn-like rootstocks and mostly basal, large showy leaves; flowers small and numerously crowded on a spadix which is generally surrounded or subtended by a simple showy leaf-like organ called a spathe.

A very numerous family found mostly in the tropics and represented in our region by but a single species.

Lysichiton kamtschatcense (L.) Schott. Western Skunk Cabbage.

A stemless marsh plant with large leaves 1—4 feet long, 3—18 inches wide, oblong or oblong-lanceolate, acute, narrowed below into a short petiole. Flowers appearing before the leaves; spathe yellow with a broad acute blade 2—6 inches long, narrowed below to a sheathing petiole 3—10 inches long; spadix 2—4 inches long, densely flowered, on a stout peduncle 8 inches or more long.

In wet and marshy spots through the Selkirks. Very abundant near Bear Creek Station on the railway, flowering in early spring.
