Flora of North America species comparison

bark smooth to vertically furrowed, shredding;

twigs with basally branched, crisped/matted, eglandular hairs, very quickly glabrate.

erect and/or prostrate;

bark smooth, sometimes peeling or shredding with age;

twigs unicellular-hairy and with flattened, glandular scales, scales often obscured by dense, ferruginous, long-crisped, unbranched, multicellular hairs.

persistent;

petiole glabrous;

blade elliptic to slightly ovate or obovate, (6–)8.5–14(–20) × 2.5–5.5(–7.5) cm, thick, coriaceous, margins entire, plane to revolute, glabrous, apex acute to obtuse or slightly acuminate, surfaces scattered eglandular-hairy (hairs branched basally, crisped, very quickly deciduous), abaxial surface ± smooth.

persistent, (fragrant when crushed);

petiole with unicellular and/or peltate scales and sometimes ferruginous, long-crisped, multicellular hairs;

blade ovate-lanceolate, sometimes narrowly elliptic to linear, 2–5 × 1.5–2.5 cm, coriaceous, margins entire, weakly to strongly revolute, glabrous, apex acute, abaxial surface with sparse to dense glandular-peltate scales without broad rim, scales often obscured by dense (to sparse), ± even covering of ferruginous, long-crisped, unbranched, multicellular, eglandular hairs usually concealing midvein, adaxial surface ± rugose with scattered, lepidote scales and sometimes also unicellular-hairy along sometimes impressed midrib.

10–20-flowered;

bracts similar to bud scales.

slightly rounded, 10–35-flowered;

bracts densely lepidote, sometimes with long-crisped hairs abaxially, margins ciliate, hairs long-crisped.

30–60 mm, glabrous.

12–25 mm, with unicellular and/or glandular-peltate scales, sometimes multicellular-hairy (hairs ferruginous, long-crisped).

opening after development of leaves (of flowering shoots), erect to horizontal, fragrant;

calyx lobes 1–1.5 mm, glabrous, except margins eglandular- and stipitate-glandular-hairy;

corolla white to pink or rose-purple, with yellowish green spots on upper lobe, broadly campanulate, 24–48 mm, outer surface glabrous, petals connate, lobes 14–30 mm, tube gradually expanding into lobes, 10–23 mm;

stamens 10, included, ± unequal, 16–37 mm.

radially symmetric, opening after leaves (of flowering shoots), ± erect, not fragrant;

calyx lobes ca. 1–1.5 mm, outer surface densely to sparsely unicellular-hairy (hairs tan) and multicellular stipitate-glandular-hairy (hairs red) on margins;

corolla white to cream, without blotch, ± rotate, 2–8 mm, inner surface densely unicellular-hairy, petals appearing distinct or only slightly connate basally, lobes 5–7 mm;

stamens (5–)8(–10), exserted, ± equal, 3.8–9.5(–11) mm;

filaments glabrous or proximally unicellular-hairy.

borne on erect pedicels, 13–25 × 4–7 mm, eglandular-hairy (hairs ferruginous, branched or unbranched) and, often, stipitate-glandular-hairy.

borne on broadly recurved pedicels, 3–5.5 × 4–6 mm (slightly longer than wide), with sparse, lepidote scales, sometimes also long-crisped-hairy, acropetally dehiscent.

without distinct tails, flattened portion of testa well developed at each end;

testa expanded, dorsiventrally flattened, loose.

somewhat elongated beyond narrow ends;

testa closely appressed.

bud scales multicellular eglandular-hairy (hairs branched basally), and unicellular-hairy (hairs short to elongate) abaxially, margins eglandular-hairy (hairs branched).

bud scales with lepidote scales, unicellular-hairy abaxially, margins unicellular-hairy.
