Leaves Opposite and Simple 



1. Leaves lobed or variable, at least lobed on vigorous shoots. 

 2. Leaves palmately lobed or parted. 



3. Plants dwarf, rigid or matted shrubs of dry, sandy, rocky 

 sites; odor sweet-musky; leaves cut into 3-7 needlelike parts, 

 opposite near stem base, alternate and crowded near stem tips, 

 often with single needlelike leaves in their axils; twigs pale, 

 more or less glandular-hairy; e. Oreg., e. Wash. 



granite gilia (Leptodactylon pungens). 

 3. Plants erect or trailing shrubs or trees of moist sites. 

 4. Leaves shortly 3-lobed above middle, often also unlobed; 

 dotlike glands on leaf margin near leafstalk; margins 

 toothed; flowers white, in flatfish-topped, compound 

 clusters (cymes); "berries" (drupes) red, squashy, each 

 with single stone; tall straggling shrubs of cool sites, e. 

 slopes of Cascades, Wallowa and Blue Mts., ne. Oreg., se. 

 Wash. 



moosewood (or squashberry) viburnum (Viburnum edule). 



4. Leaves 3- to 11 -lobed; dotlike glands lacking; fruits ("keys"

 3-parted; lobes taper-pointed, margins sharply toothed; 

 leafstalks long, often red; fruits hairless, their wings 

 usually spread at a little less than right angles to each 

 other; erect shrubs or small trees; e. slopes of Cascades,

 e. Wash. 



Douglas maple {Acer glabrum var. douglasii). 

 5. Leaves circular in outline, with 5 or more lobes. 



6. Lobes 7-11, irregularly and doubly saw-toothed; twigs 

 slender; fruits hairless, their wings in a nearly straight 

 line; erect shrubs or small trees in open sites, or trailing 

 and with vinelike twigs that dip and root at tips to 

 form thickets in wet shady sites; common w., occasional 

 e. slopes of Cascades and in Wallowa Mts., ne. Oreg. 



vine maple (Acer circinatum). 

 6. Lobes usually 5, deep, entire- or wavy-margined; twigs 

 coarse; fruits in elongated clusters, yellowish-hairy on 

 the "seeds", their wings usually spread at less than 

 right angles to each other; trees; the only native maple 

 of Oreg., Wash, with milky sap (easily seen by break- 

 ing leafstalk); common w., occasional e. slopes of 

 Cascades, Oreg., Wash. 



bigleaf maple (Acer macrophyllum) . 

 2. Leaves (at least on some of the young shoots) pinnately lobed, 

 mostly entire and oval, dark green above, paler beneath, short-
