REMARKS
According to Hassler (1911), J. guaranitica differs from J. evolvuloides by its seeds measuring up to 3.5 mm long, while J. evolvuloides seeds are up to 2.2 mm long. We also found that venation on leaves, ciliate margins and glandular trichomes are good characters to separate the species.
Jacquemontia guaranitica is also very close to J. anomala and J.warmingii , all of them with herbaceous habit and scandent stems up to 50 cm long, turning reddish in sicco, sparsely hirsute stems and leaves, lamina elliptic and with 2-3 pairs of eucamptodromous veins.Useful characters for their distinction are shown in Table 1 View TABLE .
