Atriplex Kershaw Allen Key - Sask

This key is taken from Vascular Flora of Alberta: An Illustrated Guide by Linda Kershaw & Lorna Allen, 2020.  I have added:

1a. Perennial shrubs  (2)
1b. Annual herbs  (3)

2a. Shrubs (10) 80-200 cm tall, with woody branches; fruit-bracts 8-25 mm long, on 1-8 mm stalks, irregular in shape, with 4 smooth or net-veined side wings (without small projections).  Atriplex canescens (Four-Wing Saltbush)  ABS
2b. Subshrubs (woody at base only), 10-40 (50) cm tall; fruit bracts 3-8 mm long, on 0-5 mm stalks, with 4 deep-lobed wings or with wart-like to finger-like projections <= 4 mm long (sometimes smooth, without wings or warts).  Atriplex gardneri (Gardner's Saltbush, Nuttall's Saltbush) CC

3a. Leaves with conspicuous, dark green, netted veins (kranz-type veins), visible at 12X magnification on surfaces lightly scraped with a sharp blade; flowers/fruits all similar, all with enclosing bracts .  (4)
3b. Leaves with normal, dicotyledonous veins; flowers/fruits of 2 types (except A. suckleya and A. glabriuscula), 1 large and 1 small (sometimes 1 type without fruit bracts)  (7)

4a. Leaves usually wavy-toothed and lobed, grayish green; stems sprawling or erect; branches ascending to spreading; seed radicle inferior; exotic weeds in gardens and on disturbed ground.  Atriplex rosea (Red Orache) IN UC
4b. Leaves commonly smooth-edged, whitish-gray; stems erect; branches ascending; seed radicle superior; native species of alkaline habitats, mainly in grasslands.  (5)

5a. Fruit-bracts widest above the middle, 4-8 mm long, deeply toothed and usually with large wart-like bumps.  Atriplex argentea (Silvery Atriplex) C
5b. Fruit-bracts wedge-shaped or oblong, 2-3.5 mm long, usually smooth-edged (never toothed on the edge, but sometimes with small teeth at tip)  (6)

6a. Fruit-bracts wedge-shaped, tipped with 3 tiny teeth, the upper surface smooth or with 1-2 small, wart-like bumps; leaves not conspicuously nerved.  Atriplex truncata (Wedge-Leaved Saltbush) END
6b. Fruit-bracts oblong, about 2X as long as broad, tipped with a flattened lobe, the upper surface usually with many small wart-like bumps below the lobes; leaves conspicuously 3-nerved.  Atriplex powellii (Powell's Saltbush) END

7a. Calyx of male flowers cup-shaped, with 2-3 fleshy-crested lobes, pink; fruit-bracts 2x1.5 mm, inconspicuous, smooth-sided, with edges fused to the tip; leaves thick and succulent.  Atriplex suckleyi (Rillscale)  FC
7b. Calyx of male flowers with egg-shaped lobes rounded on the back, green in the center, membranous near the edges; fruit-bract edges joined at the base only or fused up to the middle; leaves various.  (8)

8a. Fruit-bracts green and leafy (herbaceous) or membranous throughout, without spongy inner tissue.  (9)
8b. Fruit-bracts more or less thickened with spongy inner tissue, especially near the base.  (12)

9a. Fruit-bracts round, always smooth-edged and without side angles.  (10)
9b. Fruit-bracts never round, often toothed and usually with side angles  (11)

10a. Female flowers of 2 types: most with dull brown, vertical seeds enclosed by a pair of showy, 5-18 mm bracts, and a few with shiny black, horizontal seeds with 5 small tepal lobes and no bracts; fruit-bracts notched or broadly rounded at the base, 5-18 mm long.  Atriplex hortensis (Garden Atriplex, Garden Orache) IN C
10b. Female flowers all with vertical seeds enclosed by fruit bracts <= 6 mm long; fruit-bracts shortly tapered to the base but of 2 sizes, 5-6 mm fruit-bracts with dull yellowish brown, 2-3 mm seeds and 2 mm fruit-bracts with shiny black <= 1.5 mm seeds.  Atriplex heterosperma (Two-Scale Saltbush) IN R, but common in Regina at least

11a. Fruit-bracts diamond-shaped, with edges fused almost to the middle and side angles clearly developed; uppermost flower/fruit clusters densely compressed, with fruit-bracts of more or less uniform size; upper leaves green above and below.  Atriplex patula (Spear Saltbush, Spreading Orache) IN FC
11b. Fruit-bracts egg-shaped to triangular-egg-shaped, without side angles, the edges separate to the base; uppermost flower/fruit clusters with loosely spaced fruit-bracts; upper leaves whitish beneath.  Atriplex oblongifolia (Oblong-Leaf Orache) IN VER?

12a. Leaves thickened, strongly 3-veined from near the base; lower leaves linear to lance-shaped or egg-shaped.  Atriplex dioica (Thickleaf Orache, Saline Saltbush, Saline Atriplex) C
12b. Leaves neither thickened nor 3-veined; lower leaves triangular  (13)

13a. Flowers/fruits in small, irregularly spaced clumps, forming loose clusters with leafy bracts to the tip; fruit-bracts thick and spongy, with edges fused from the base to the middle; seeds >2.5 mm wide, usually all dark brown to black, irregularly lens-shaped, all similar; seed radicle more or less strongly pointing upward from the middle; rare native species, ne AB.  Atriplex glabriuscula (Glabrous Orache) ABS
13b. Flowers/fruits close and touching (sometimes irregularly spaced) in spherical clumps, forming tight clusters with leafy bracts only at the base; fruit-bracts thin to slightly spongy thickened, with edges fused only at the base; seeds usually of 2 different forms, mostly <2.5 mm wide and glossy-black but also some larger and dull brown; seed radicle pointing obliquely up or out from near the base; fairly widespread in moist, saline sites in c-s AB, probably exotic.  Atriplex prostrata (Hastate Saltbush) IN C
