Common Name: PRIMROSE FAMILY Habit: Annual, perennial herb, or subshrub, glabrous to glandular-hairy. Leaf: simple, +- basal, petioled or not; stipules 0. Inflorescence: scapose umbel, subtended by involucre. Flower: bisexual, radial; parts in 4s or 5s (6s); calyx deeply lobed, often persistent; corolla lobes erect or spreading to reflexed; stamens epipetalous, opposite corolla lobes; ovary superior, 1-chambered, placenta free-central, style 1, stigma head- or dot-like. Fruit: capsule, 2--7-valved or circumscissile. Seed: small, few to many. Genera In Family: +- 8 genera, 600 species: northern hemisphere; several ornamental (Primula). Note: Based on molecular evidence, non-rosette terrestrial members of Primulaceae as treated in TJM (1993) moved to Myrsinaceae, and Samolus to Theophrastaceae; based on the same evidence, Primulaceae has been treated alternatively to include all of Myrsinaceae and Theophrastaceae. Taxa of Dodecatheon in TJM2 treated here in Primula. Unabridged Note: Recent molecular work has led to new understanding of relationships in Ericales. As treated here, non-rosette, terrestrial members of Primulaceae s.l. have been removed from that family and inserted in Myrsinaceae. Myrsinaceae, then, is characterized by synapomorphies of dark dots or streaks on stems, leaves, or flowers, short corolla tubes, seeds immersed in the placenta, and -- for woody members -- wood lacking rays or with only multiseriate rays. Primulaceae, Myrsinaceae, Theophrastaceae, and Maesaceae (a recent segregate of tropical trees), now constitute a closely related, monophyletic clade. A more recently proposed, alternative taxonomy treats all members of that large clade within an expanded Primulaceae. eFlora Treatment Author: Anita F.

2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records 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.
