Arctostaphylos pringlei subsp. drupacea


Higher Taxonomy
Family: EricaceaeView DescriptionDichotomous Key
Common Name: HEATH FAMILY
Habit: Perennial herb, shrub, tree. Stem: bark often peeling distinctively. Leaf: simple or 0, generally cauline, alternate, opposite (whorled), evergreen or deciduous, often leathery, petioled or not; stipules 0. Inflorescence: raceme, panicle, cyme, or flowers 1, terminal or axillary, generally bracted; pedicel often with 2 bractlets. Flower: generally bisexual, generally radial, bell-shaped, cylindric, or urn-shaped; sepals generally (0)4--5, generally free; petals generally (0)4--5, free or fused; stamens (2--5)8--10, free, filaments rarely appendaged, anthers dehiscing by pores or slits, awns 0 or 2(4), seemingly abaxial, reduced or elongate, generally curved; nectary generally present at ovary base, generally disk-like; ovary superior or inferior, chambers generally 1--5, placentas axile or parietal, ovules 1--many per chamber, style 1, stigma head- to funnel-like or lobed. Fruit: capsule, drupe, berry. Seed: generally many, winged or not.
Genera In Family: +- 100 genera, 3000 species: generally worldwide except deserts; some cultivated, especially Arbutus, Arctostaphylos, Rhododendron, Vaccinium. Note: Monophyletic only if Empetraceae included, as treated here. Ledum included in Rhododendron. Non-green plants obtain nutrition from green plants through fungal intermediates.

Genus: ArctostaphylosView DescriptionDichotomous Key


Common Name: MANZANITA
Habit: Shrub to small tree, prostrate to erect. Stem: old stems generally +- red, smooth, bark generally thin, peeling, or generally +- gray or red-gray, shredding and rough; burls at base, woody, sprouting after fire, or generally 0; twig hairs 0 or generally +- like those on inflorescence axes, bracts. Leaf: alternate, evergreen; blade flat to convex, base lobed to wedge-shaped, clasping stem or not, margins generally flat, surfaces with stomata generally both abaxially, adaxially, alike in color, hairiness, less often only or fewer abaxially, generally differing in color, hairiness. Inflorescence: +- raceme (generally 0--1-branched) or panicle (generally 2--10-branched), terminal, nascent inflorescence present following stem growth, generally late spring through winter, remaining dormant 4--6 months prior to flower (except in Arctostaphylos pringlei subsp. drupacea); branches 0 or raceme-like; flower bracts leaf-like, generally flat, or scale-like, often folded, keeled, tips rounded to acute to awl-shaped. Flower: radial; sepals 5(4), free, persistent; corolla conic to urn-shaped, lobes in number = sepals, short, rounded, curved back, white to pink; stamens 2 × number of sepals, included, filaments swollen, generally hairy at base, anthers dark red, awns elongate; ovary superior, on disk, 4--10-chambered, ovule 1 per chamber. Fruit: drupe, generally +- depressed-spheric to spheric; flesh generally thick, +- mealy, occasionally 0; stones 2--10, free, fused, or some fused.
Species In Genus: +- 62 species: North America (especially California) to Central America, Eurasia. Etymology: (Greek: bear berries)
Unabridged Note: Rosatti (1986 Syst Bot 12:61--77) showed that in Arctostaphylos uva-ursi little to none of the variation in hairs (including length, glandularity) is genetically based.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
