Bebbiana: 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
bullet

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]

bullet

Low to tall shrubs or trees; not confined to subarctic regions.  NOT [Dwarf shrubs <= 0.15 m (15 cm) tall; subarctic regions]

bullet

Shrubs, usually with several stems; ovaries glabrous or hairy.   NOT  [Trees, with a single trunk, or with several trunks of tree stature; ovaries glabrous]

bullet

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]

bullet

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]

bullet

Ovaries hairy.  NOT [Ovaries glabrous]

bullet

Ovaries sparsely short-silky; stipes long (1.4 – 6 mm); styles short (0 – 0.5 mm. NOT [Ovaries without the above combination of characteristics – if appearing sparsely short-silky, then stipes shorter than 1.4 mm or styles longer than 0.5 mm]

bullet

Stipes 2 – 6 mm; floral bracts 1 – 3 mm, tawny; catkins 16 – 80 mm, stout, slender or subglobose; flowering branchlets 1 – 26 mm; leaf blades narrowly oblong, narrowly elliptic, elliptic, oblanceolate or obovate, 2 – 3 – 4 times longer than wide; leaf blade veins protruding on lower surface; ferruginous hairs absent on leaf blades and ovaries.  NOT [Stipes 1.4 - 4 mm; floral bracts 1 – 2 mm, brown, tawny, light rose or bicolor; catkins 12 - 39 mm, stout to globose; flowering branchlets 1 – 11 mm; leaf blades strap-shaped to very narrowly elliptic, 5 – 7 – 9 times longer than wide; leaf blade veins flat on lower surface; ferruginous hairs may be present on leaf blades and ovaries]
