Upon senescence and drying, the entire inflorescence snaps off near the base, along a predetermined zone of abscission (Roche, 1991), and disperses as a tumbleweed, scattering hundreds or even thousands of mericarps as it rolls.
The mericarps of some Salvia species are known to float, and they are small enough to be carried by flowing water (rivers or streams) or sheet flow as a result of heavy rainfall (rain wash).
In Salvia, ombrohydrochory occurs when raindrops strike the calyces containing the mericarps. The raindrop depresses the calyx briefly, and then the pedicel springs back to a neutral position, thereby ejecting the mericarps from the calyx.
150 cm above the plants) dispersed mericarps 5-109 cm from the plant (mean = 35.1 cm; mode = 29 cm; n=75).
Even without bristles, hooks, or barbs, the mericarps of some Salvia species may be dispersed by animals, or have been shown to have the potential for epizoochorous dispersal.
They combed mericarps into sheep and cow pelts and shook the pelts for one hour.
marlothii fruits are 5-winged, and asymmetrically schizocarpic with three wings (one median and two marginal) on one mericarp and two lateral wings on the other (Fig.
3C, E in Liu et al., 2006) fruits have eight wings, four on each mericarp. The endocarp is fusiform, longitudinally ribbed and capped by persistent remains of the calyx and styles.
The fruit is cordate-shaped with two laterally compressed schizocarpic mericarps. A fimbrial vein is developed on each mericarp (Fig.
This asymmetral pattern suggests that these disseminules are mericarps of the kind typical for Apiaceae, with three or five longitudinal veins occurring on the dorsal side of each mericarp but only a single vein running medially on the ventral side.
Each valve or mericarp with two auriform wings spreading from an obovate thickened central body; veins irregular in course and spacing, with large areoles.
In some cases the entire fruit is the unit of dispersal and in others the fruits are dehiscent as capsules that shed multiple seeds, or schizocarpic, falling into separate winged mericarps at maturity.
