Pedicellaris: Answers
to key questions in
Conifers & Catkin-Bearing Trees and Shrubs of
Saskatchewan, Fascicle 5, Flora of Saskatchewan by Anna Leighton leading
to this species. The answers are in the order you would normally work
through the key.
 | Catkins usually
flowering as leaves emerge, sometimes just before leaves emerge or
throughout the season, subtended by small green leaves of the flowering
branchlet that supports them. NOT [Catkins usually flowering
before leaves emerge, borne directly on bare branches (sessile) and
subtended by 1 - 3 short, greenish or brownish, caducous bract-like
leaves] |
| Low to tall shrubs or
trees; not confined to subarctic regions. NOT [Dwarf shrubs <=
0.15 m (15 cm) tall; subarctic regions] |
| Shrubs, usually with
several stems; ovaries glabrous or hairy. NOT [Trees,
with a single trunk, or with several trunks of tree stature; ovaries
glabrous] |
| NOT [Plants flowering as
leaves emerge or throughout the season, often bearing branched catkins;
leaf blades linear or strap-shaped, 9 ? 14 ? 24 times longer than
wide, up to 11 mm wide with margins remotely spinulose-serrulate, the
teeth widely spaced; hairs on leaves white, ferruginous hairs lacking;
plants forming extensive colonies by root shoots] |
| Petioles without
glandular dots or lobes at distal end, or with occasional, inconspicuous
dots; floral bracts not as above, if conspicuous and pale, then not
deciduous. NOT [Petioles with glandular dots or lobes at distal
end; floral bracts pale tawny, 1.2 ? 4 mm, conspicuous during
flowering, deciduous after flowering] |
| Ovaries glabrous. NOT
[Ovaries hairy]. |
| Lower surfaces of leaf
blades glaucous, sometimes obscured by dense hairs. NOT [Lower surfaces
of leaf blades not glaucous, usually glabrous but sometimes hairy.] |
| Catkins stout to
subglobose, 11 - 32 mm; styles immeasurably short (0.1 - 0.24 mm);
ovaries often reddish; leaf blade upper surfaces glaucous, margins
entire; plants to 2 m tall. NOT [Catkins slender or stout, 16 - 85 mm;
styles usually measurable (0.2 ? 0.6 mm); ovaries rarely reddish; leaf
blade upper surfaces not glaucous, margins toothed or sinuate; plants to
7 m tall.] |
