compact and rigid, the bark smooth, reddish-brown; branchlets pale-green and glaucous, gla- 
brous or rarely glandular-pubescent; leaf-blades oblong, elliptic, or commonly ovate, obtuse and

entire or on vigorous shoots serrate, very pale-green and glaucous on both surfaces, glabrous 
or rarely glandular-pubescent on the margins toward the base; petioles 7-10 mm. long, glabrous 
or rarely glandular-pubescent, twisted giving the leaves a vertical position; flowers in short 
terminal panicles or racemes; branches of the inflorescence glabrous or rarely glandular- 
pubescent; lower bracts foliaceous, those subtending the flowers 3-6 mm. long, triangular, 
spreading or recurved, firm; pedicels glabrous or rarely glandular-pubescent; calyx-lobes

41. ORNITHOSTAPHYLOS Small, gen. nov. 
Shrubs with erect, stiff, much-branched stems. Leaves opposite, sometimes whorled, 
numerous, persistent; blades narrow, thick, entire, revolute, very short-petioled. Flowers 
numerous in axillary and terminal branching panicles with slender rachis and pedicels, the 
bracts and bractlets minute. Calyx persistent; lobes broad, about as long as the tube, spread-

Ovary 5-celled or rarely 4-celled, depressed, seated on a thick disk, puberulent; style columnar; 
stigma minute. Drupe dry, with a smooth thin pericarp and very thin pulp, the nutlets 2- 
celled by a partition from the inner angle.
