0 a strong feeling of disapproval that most people in a society have about something, especially when this is unfair -- 恥辱;(尤指不公正的)惡名
1 the top of the central female part of a flower, where pollen is received -- (花)柱頭
By 18h45-19h15 the flowers were open and the anthers and stigmas were exposed.
Their stamens were light green and the stigmas pink.
Four out of 24 stigmas (17%) had less than 30 conspecific pollen grains, while the rest had 270 grains or more.
In these cases, pollen was transferred from staminate flowers to pistillate stigmas with a small paint brush.
Moreover, because they seldom find their way to piassava stigmas, they are at best casual pollinators.
The insects touched stigmas and anthers when collecting pollen and nectar.
Although general morphological stigmas are immediately recognizable, most notably the common atrioventricular junction, small differences can help define the specific forms within this spectrum.
Apart from exposure to societal stigmas, a second community-level risk is the dysfunctional informal social networks.
