erigeron karvinskianus, Karwinsky's fleabane, Latin American fleabane, Mexican fleabane, Santa Barbara daisy, Spanish daisy
|
| Perennials, 3–20(–30) cm; taprooted, caudex branches relatively short and thick. |
Perennials, often short-lived, 10–100 cm; fibrous- or taprooted, caudices woody, usually simple, stems sometimes rooting adventitiously. |
erect, loosely to closely, sparsely to moderately strigose (hairs 0.1–0.9 mm), usually minutely glandular (glands barely evident), sometimes eglandular. |
erect to sprawling or decumbent (small leaf tufts in axils of larger leaves), sparsely strigose to glabrate, eglandular. |
basal (usually persistent) and cauline (petioles prominently ciliate at least on proximal portions, hairs spreading, thick-based); basal blades linear-oblanceolate, 20–100 × 1–4 mm, margins entire, faces strigose, eglandular; cauline usually restricted to proximal 1/2 of stems, slightly reduced distally. |
basal (and proximal cauline withering by flowering) and cauline; cauline blades elliptic to obovate, mostly 10–40(–50) × 5–13 mm, usually relatively even-sized along stems, margins entire or with 1–2 distal pairs of acute, mucronulate teeth or lobes, faces sparsely and loosely strigose to hirsuto-villous, eglandular. |
3.5–5(–6) × 7–12 mm. |
2.5–3.5 × 7–10 mm. |
(35–)45–100; corollas white, sometimes pink or bluish, 5–10 mm, laminae (0.8–1.1 mm wide) primarily reflexing, sometimes also weakly coiling at the tips. |
45–80; corollas 5–8 mm, laminae not or slightly coiling, white, sometimes drying pinkish. |
(2.5–)2.7–4.2 mm (throats indurate and inflated, densely puberulent). |
2–3.1 mm. |
in 2–3(–4) series, coarsely hirsuto-villous, sparsely to moderately minutely glandular. |
in 3–4 series, sparsely strigose to hirsuto-villous or glabrate, sometimes minutely glandular. |
1(–3). |

Plants from Chaffee and Fremont counties, Colorado, have strigose leaves and the compact habit of Erigeron engelmannii but sparsely spreading-hirsute stems; they may be intermediate between E. engelmannii and E. concinnus. Unusual variation in the pappi of E. engelmannii also suggests that the species needs study and better definition. A. Cronquist observed that “Erigeron engelmannii intergrades completely with E. pumilus, yet has two geographic subspecies of its own, and shows no distributional similarity to the [taxa] of E. pumilus,” and that E. engelmannii is “smaller and more delicate, with shorter finer hairs, and [has] smaller heads with usually fewer ligules.” (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron karvinskianus is most abundant in tropical and subtropical regions; it is widely cultivated and escaped. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
