This pretty little flower can only be enjoyed when the sun is out. It is in the same family as okra, hollyhocks, and cotton. Unlike many other members of the Mallow Family, these flowers are small, less than half-inch. Note the bright red nectar guides on the petals.
For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the Bristly-Fruited Mallow, we have 473 observations. Compared to other species in this Class, this species is extremely common.
A two-sample t-test can be used to determine whether the trend in observations of the Bristly-Fruited Mallow is the same as the trend in observations of Magnoliopsida. Is this species just as common, as a proportion of all observations, as it once was? The answer is no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=12.58, p<0.001)
How do observation rates of the Bristly-Fruited Mallow differ from those of Magnoliopsida? To answer this, we examined the percentage of observerations for Magnoliopsida that were observations of the Bristly-Fruited Mallow each year. We then correlated this percentage with observation year. If observations of the Bristly-Fruited Mallow are becoming more common relative to other species of Magnoliopsida, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.32), with a negative slope (m = -.000), suggesting that the Bristly-Fruited Mallow may be in decline relative to other species of Magnoliopsida. This correlation is statistically significant. (F = 24.17, p<.05)
