Quantitative anatomy of the stomata of Ipomoea cavalcantei (nursery and canga), and I. marabaensis. (A) Stomatal density. (B) Stomatal funcionality. (C) Polar diameter. (D) Equatorial diameter. ns, no statistically significant difference; *, **, with significant statistical difference (p < 0.05). The asterisks mean * = 0.05; ** = 0.01.

Background
Accurate species identification is the first step towards establishing conservation strategies, especially regarding rare and threatened species, such as those studied here. Moreover, understanding the responses to the environment and growing conditions of endemic species is necessary for its conservation. This study compares the leaf an...

... but in I. marabaensis the diacytic type ( Fig. 2F) also occurs. The leaves of individuals of I. cavalcantei grown in a natural environment did not differ from I. marabaensis in stomatal density, functionality, and size (Figs. 3A-3D). On the other hand, the leaves of I. cavalcantei under cultivation conditions showed lower stomatal density ( Fig. 3A) but higher stomatal functionality ( Fig. 3B) and stomata with higher polar diameter (Fig. ...
