Flora of North America species comparison

creeping or prostrate;

bark ± smooth;

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

bark smooth to vertically furrowed, shredding;

twigs multicellular eglandular-hairy (hairs branched basally, crisp/matted), glabrate in age.

persistent, (fragrant when crushed);

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

blade ± linear, 2–5 × 1–4 cm (often much longer than wide), coriaceous, margins entire, revolute, glabrous, apex acute, abaxial surface with sparse to dense, glandular-peltate scales without broad rim, scales often obscured by dense (to sparse), ferruginous, long-crisped, multicellular hairs sometimes forming dense, ± uniform mat, adaxial surface rugose with scattered, lepidote scales and sometimes also with white, unicellular hairs along impressed midrib, midrib usually lanate.

persistent;

petiole multicellular-hairy (hairs ± branched), often glabrescent;

blade elliptic to obovate or slightly ovate, (5–)6–12(–17) × (2.5–)3.5–6(–7.7) cm (length/width ratio 1.3–3.5), thick, coriaceous, margins entire, revolute to plane, glabrous or sparsely hairy along margins (hairs branched, ephemeral), apex rounded/mucronate to obtuse or acute, surfaces sparsely eglandular-hairy (hairs basally branched, crisped, quickly deciduous), abaxial surface minutely, obscurely papillose.

slightly rounded, 10–35-flowered;

bracts lepidote abaxially, margins ciliate, long-crisped-hairy, sometimes also unicellular-hairy.

12–20-flowered;

bracts similar to bud scales.

5–26 mm, sparsely eglandular-hairy (hairs ferruginous, elongated), with ferruginous, long-crisped, unicellular and/or peltate scales, sometimes also long-stalked, multicellular glandular-hairy.

10–50 mm, sparsely to moderately multicellular eglandular-hairy (hairs ferruginous, branched, crisped), glabrate in age.

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

calyx lobes ca. 1 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 often densely unicellular-hairy, petals appearing distinct or only slightly connate basally, lobes 5–7 mm;

stamens 10, exserted, ± equal, 4.4–8.5 mm.

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

calyx lobes 0.5–1.7 mm, glabrous or eglandular-hairy;

corolla deep pink to purple, rarely white, usually with yellowish-green spots on upper lobe, campanulate, 27–50 mm, glabrous on outer surface, petals connate, lobes 15–30 mm, tube gradually expanding into lobes, 12–28 mm;

stamens 10, included, ± unequal, 19–39 mm; (ovary multicellular eglandular-hairy).

borne on apex of sharply recurved pedicels, 2.5–5 × 1–3 mm (only slightly longer than wide), with sparse to dense, lepidote scales, acropetally dehiscent.

borne on erect pedicels, 10–23 × 3.5–7 mm, eglandular-hairy (hairs ferruginous, branched).

somewhat elongated beyond narrow ends;

testa closely appressed.

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

testa expanded, dorsiventrally flattened, loose.

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

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