Table 1. Comparison of morphological characters Michaelmoelleria, Cathayanthe, Deinostigma and Tribounia.
| Characters | Michaelmoelleria | Cathayanthe | Deinostigma | Tribounia |
| Life form | perennial | perennial | perennial | probably annual |
| Stem | glabrescent to glabrous when ageing | rhizomatous, stemless | multifarious, from short and constrictive to procumbent; from glabrous to pubescent and puberulent | with hairs and often hooked at the tip |
| Leaves | alternate on elongate aeriald stem, 12-20 or more | few, 4-8, basal | alternate, numerous | opposite, numerous |
| Lea-blade | ovate to elliptic, both surfaces glabrous | oblanceolate to obovate or elliptic, adaxially whitish to brownish sericeous, abaxially appressed pubescent | multifarious, slightly peltate or not, glabrous or eglandular pubescent on both surfaces | ovate, densely pubescent adaxially and abaxially mostly with eglandular pubescents (occasional glandular pubescent present in Tribounia grandiflora) |
| Calyx | Actinomorphic, 5-parted to the base | zygomorphic, 2-lipped | divided to base, elliptic, those on ventral side slightly longer and wider | equally 5-partite almost to base |
| Corolla | tube narrowly curving to zigzag infundibuliform-tubular, and bent at about 90° angle in the middle of corolla tube, and gradually slightly swollen from the middle to the base of the tube; dramatically enlarged to be trumpet-shaped from the middle of the corolla tube toward the limb | tube tubular, nearly straight to slightly bent, slightly gibbous abaxially toward limb, much longer than limb | tube infundibuliform, lower lip 3-lobed, upper lip 2-lobed, lobe apices rounded | zygomorphic, of a narrow lower tube which widens into an infundibuliform upper tube which has a prominent boss on the dorsal surfacew |
| Fertile stamens number | 4 | 2 | 2 | 2 |
| Ovary | cylindric-linear, glabrous, 3.5-4 cm long | narrowly ellipsoid, ca. 6 mm long | fusform, long or short, with different indumentum, from glabrous to glandular- and eglandular-puberulent | cylindrical, densely glandular pubescent, ca. 6 mm long in T. venosa, 7.5-11.0 mm long in T. grandiflora |
