Burke: Delphinium nudicaule vs. Delphinium multiplex

	Delphinium nudicaule	Delphinium multiplex
		Kittitas larkspur
Habit		Rather stout perennial from thick, fibrous roots, the several stems simple, erect, hollow, 5-10 dm. tall, glandular-pubescent at least above.
Leaves		Basal and lower cauline leaves thick and fleshy, long-petiolate, 5-12 cm. broad, 2-3 times lobed into oblong, rounded, entire segments; mid- and upper cauline leaves sub-sessile, crowded, more narrowly lobed and acutely segmented.
Flowers		Inflorescence simple or compound, with yellowish, glandular hairs, the racemes elongate and spike-like; sepals 5, purplish-blue with a greenish-white mid-stripe, 9-11 mm. long, oblong-elliptic, spread with the tips cupped forward, the spur much longer than the blade of the upper sepal; petals 4, pale to dark blue; stamens numerous; pistils 3.
Fruits		Follicles 8-13 mm. long, glandular-pubescent.
