Fruit: generally capsule, generally ellipsoid, loculicidal [indehiscent, 1-seeded].

Genus: DiplacusView DescriptionDichotomous Key


Common Name: MONKEYFLOWER
Habit: Annual to shrub, glabrous to hairy. Stem: generally erect. Leaf: generally +- sessile, generally toothed or entire. Inflorescence: raceme, bracted, flowers 1--4 per node. Flower: pedicel generally < calyx; occasionally cleistogamous; calyx generally green, lobes 5, generally << tube, generally unequal; corolla semi-persistent, shriveling on the developing capsule (deciduous, in D. mohavensis and D. pictus), white to red, maroon, purple, orange, or yellow, tube-throat floor generally with 2 longitudinal folds; anther sacs spreading; placentas 2, parietal; stigma lobes generally included. Fruit: generally ovoid to lanceolate in outline or nearly cylindric, dehiscent to near base along the upper suture, and at least in distal half along lower suture, or sometimes indehiscent, chambers 2. Seed: many, generally < 1 mm, ovoid, +- yellow to dark brown.
Etymology: (Greek: two cake, from the separated placentas in fruit at dehiscence) Note: Limb width measured between most distant points across corolla face.

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.
