Flora of North America species comparison

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.

bark smooth to vertically furrowed, shredding;

twigs sparsely to moderately scattered, multicellular stipitate-glandular-hairy and eglandular-hairy (hairs unbranched), also unicellular-hairy, glabrate in age.

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.

deciduous;

petiole multicellular eglandular- and stipitate-glandular-hairy and unicellular-hairy;

blade elliptic to obovate, 2.3–17 × 0.8–5.5 cm, thin, membranous, margins entire or undulate, plane, widely scattered to densely eglandular-hairy, apex acuminate, abaxial surface scattered stipitate-glandular-hairy, adaxial surface scattered stipitate-glandular-hairy and eglandular-hairy, especially near margins.

slightly rounded, 10–35-flowered;

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

5–15-flowered;

bracts similar to bud scales.

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

5–26 mm, stipitate-glandular-hairy.

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.

opening before development of leaves, erect to horizontal, fragrant;

calyx lobes 0.3–8.5 mm, glandular-ciliate, often also scattered, stipitate-glandular-hairy;

corolla pale to deep pink, sometimes white, with orange-brown or red spots on upper lobes, widely campanulate and appearing ± 2-lipped due to more extensive connation of 3 upper lobes and 2 flaring, slightly longer lower lobes, 18–37 mm, glabrous on outer surface, petals connate, upper lobe 10–18 mm, lateral lobes 14–24 mm, lower lobes 15–30 mm, tube gradually expanding into lobes, 3–8 mm (to 1/4 as long as lobes);

stamens (5–)7, not or only slightly exserted, ± unequal, 12–38 mm;

filaments glabrous.

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.

borne on erect pedicels, 9–17 × 3–6 mm, very sparsely to moderately multicellular stipitate-glandular-hairy.

somewhat elongated beyond narrow ends;

testa closely appressed.

with ± stellate-globular tails;

testa tightly appressed.

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

bud scales glabrous or nearly so abaxially, stipitate-glandular-hairy, often also unicellular-hairy along margins.
