However, they can be easily distinguished because C. emarginata has farinose hairless petals and a cuspidate leaf apex, while C. trifolia has slightly to densely puberulent petals and an acute leaf apex.</p><p>Generally in Thai Cayratia the habit type seems to be correlated with seed morphology. Thus, species with herbaceous habit have seeds with an adaxial side with 2 faces and lack a deep cavity and occluding membrane, while species with a woody habit have seeds with their adaxial side possessing a cavity occluded by a membrane. Although no C. emarginata seeds have been seen, it is likely that if this character correlation is maintained, this species has seeds with an adaxial side with 2 faces and no cavity.</p><p>The specimen collected in the Sa Kaeo province, had a sticky secretion on the stems. In addition, all of the specimens examined grow in limestone terrain.</p><p>We have used as a holotype the duplicate of the specimen held in P, because it contains flowers and is a good representative of the species. This specimen was previously identified as Cayratia mollissima . It can be easily differentiated from it because C. emarginata has a herbaceous habit and its leaves are generally much smaller (3–6 by 1.5 –3 cm), while C. mollissima has a woody habit and bigger leaves (7–20 by 2.5 –10 cm).</p></div>	https://treatment.plazi.org/id/03F587C5DD49FFC2FFE1FA31FD478FE2	Public Domain	No known copyright restrictions apply.
